BBB Industries have diagrams for free online. Check for power to fuses and relays to the injectors and a pulse signal to the injectors would be a first step. Check YouTube for "injector voltage test" will show you how visually.

Well, it sounds like it is a problem in the fuel pump circuit. A lot of problems don't set a code, but if you know someone with a code reader or scanner, or if you get it running to drive it to Autozone or O'Reillys, Pep Boys, or most auto parts stores , you can get a free code scan service. Only takes a few seconds, good to know if your engine computer has detected anything.

So you put a new pump in. If it turns on, it should put enough fuel pressure up to the engine. Here's how to check if the pump is turning on as it should to start the car: turn the ignition key to on, not start, and listen for the fuel pump to turn on for 2 seconds. You should hear a hum or buzz from the tank for about 2 seconds. If you do hear it, and the fuel filter is not plugged up, the engine should have enough gas to start. If the filter is not plugged up, and the only way to start the engine is with starting fluid, then the problem may be in the fuel injector circuit.

Now if you do not hear the fuel pump turn on (2 seconds) with key in on, then the problem is in the fuel pump circuit. This can be difficult to diagnose, not feasible without a voltmeter and a wiring diagram of the car, so you would probably need experienced help. If you put the pump in yourself, you are a good gear head. buy a digital voltmeter and a repair manual and go to learning while you fix it your self.

    Ronald, the most important verification of the fuel pump (and the fuel filter as well), WHEN you have a no start or hard starting situation and you want to know if the right amount of gas is getting to the engine, the most important verification is to check the fuel pressure at the pressure test port on the engine. If pressure is correct to Mitsubishi specification, with just key on, not start, then your pressure at the injectors should be spot on, and if the computer signals the injectors, the engine should start at the first impulse. I'm pretty sure that some national parts stores will loan (or at least rent) fuel pressure gauges. At the pressures required for multiport injection -upwards of 45 psi and above- the correct pressure is critical for proper operation.

SOURCE: the check engine light comes on and then the engine dies

If you check under the hood and see if the fuel pump relay is clicking on and off. This may be your problem.

SOURCE: No Fuel??? Not starting.

You have fuel flow but the question now is are the injectors pulsing. Given the year of the truck my gut says your ECU, Engine Control Unit, has failed. Mitsubishi had issues with the capacitors in their early 90's cars, trucks SUVs. I have been thru this with two monteros and one 3000GT, very common. To check your injectors rent a set of NOID lites from Autozone our such. Remove an injector plug and itstall a noid light. Turn the engine over, if no flash, no pulse. Remove the ECU and carefully open it up. Look for the capacitors, there should be 3, look under the capacitors on the board; if there is a grease like substance, often time it has a green hew to it, then the capacitor(s) have failed. It may be possible to replace the capacitors or simply purchase a rebuilt ECU. Be ceratin the MD number matches on the new unit.
Please let me know your results and if this had assisted you.
Thanks, Tom

SOURCE: no fuel

It could possibly be a faulty Crankshaft Position Sensor. If the computer doesn't see that the crankshaft is spinning, it won't activate the fuel pump.

Intermitent dieing


metro, 1.0Liter>? 3cyl

or the LSI with the 4 cylinders.? TBI and not MPI

yours is TBI, One injector engine MPI came out in 1998.

your car has OBD2 computer so any scan tool will show

why spark is gone (if). (precursors ) cranked for 5seconds,



(what does has fuel mean? wet spark plug tips?)

got spark? it stalls and wont restart have half hour>?

intermittent engine stalling. seems starts cold and fails hot engine.



on all EFI, (besides a tune up) we check this.. (a full 60k tune up?)



1: if you loose 12vdc main power, at stall>? (dash lamps dim or die,

head lights dim or die? bingo!

no.

2: can you save the stall with a fast right foot?

a: easy (isc stuck closed?)

b: tad hard. (EGR main stuck open or or low fuel pressure)

c: impossible. (lost spark or near zero fuel pressure, 10PSI is no good.

which is it? and is #1 key to solving any EFI stalls !!!

3: lost engine compression say hot, never set valve lash ever? or cam belt slips or has slipped. ever do a 60k belt on cam, ever?



4: bad spark, weak, or dead, at fail, if spark timing is way off (check it) that mean the cam belt is bad and slipped. 60k mile service skipped.

5: bad fueling, (last) and the most complex.





that is the correct order, you can skip around but it only delays the discovery.

1 Bad DC power, 2 bad compression,3 bad spark 4bad fueling.

Example1:

you key on, and get CEL glowing, most likely the ECU has power

as that lamp tells you it has.

then you find its flooding, 99% are never tuned up, or lost spark

you check spark its gone, you check that cam spins (oil filler hole)

you connect scan tool and crank for 5seconds, the tool shows

CKP or CMP bad. the DTC error codes will tell you!!!

if spark is good, use the operators guide , for flooding

it says :crank at wide open throttle to clear foods"

it starts, and floods again. oops.

you check spark timing.and find the timing way off, retarded.

bingo the 60k belt slipped, fix belt.

you check compression (it should have been first) and find its 80psi

not 150 PSI (W.O.T)

belt slipped. (they all do , ignored, )



lets do one more,

: example.2

spark good,!

timing good on dizzy!

compression as spec. 150 x3 or 4.

it floods.

i find fuel pressure at 60PSI , 2 times spec.

i find the regulator bad, it fails all 6 tests in the fSM on this device.

or the fuel return line is clogged.

hope his helps. post engine size, and cyl. count.

and if ever tuned up this decade.

The engine turning over with the starter & cranking
is the same thing
You have a No Crank or No Start?
You may hear the fuel pump, but have to check

You may have bad ignition coils

The fuel pressure sounds too low. Is it multi-port injection? Check the fuel pressure against your specs for the car and engine. MPFI systems usually require 40-50 psi.

1997 Jeep Grand Cherokee keeps cutting off and won't start some times


I would start by going to an auto parts store and having them scan the computer for codes, even if the engine light is not on. i have heard about auto part stores saying they can not scan if light is not on. i am not sure if it is the scan tool they use or what but sometimes there could be a pending code where the computer is waiting to see the problem again before turning light on. if this is the case then ask them to scan it anyway or go to a shop and ask them to do it. the reason for this is that these trucks have crank sensor problems.

the next time is dies check for spark, remove a sparkplug wire and place a screw driver into the boot of the wire and place it near a ground, a metal surface and then have someone crank the engine and see if there is spark. if there is no spark or you got a code of the crank sensor then i would replace the crank sensor, but if you have good spark and truck will not start then try spraying starting fluid into throttle body and see if it starts and dies out if it does then fuel pump problem.

If you have a fuel pressure gauge then hook that up and crank engine and see if you have fuel pressure and how much.

I will say that this does sound like a bad crank sensor, it dies and then wont start for a while ...

I have a dodge caravan, started up fine, ran 5 seconds then dies. Go to restart, no crank. Came back a few hours later. Started up just fine, 5 seconds later dies. No crank again. Code P1193 is the only...


Diagnostic Test Code (DTC) P1193 is a manufacturer specific code (not listed in SAE J2012 as a standard generic fault code). Dodge lists the code definition as "Inlet AIr Temperature (IAT) Sensor Voltage High"
This code can have an affect on how your engine runs because the engine controller uses input from this sensor to adjust fuel and timing controls.

However, the symptoms you are describing do not sound like something that an IAT sensor would cause. It sounds more like your immobilizer is shutting things down (security system "thinks" somebody is trying to steal the vehicle)

I would recommend scanning your Body Control Module (BCM) and checking for active codes for your security/imobilizer system. It would probably also be wise to scan the REST of your computer network (ABS, IPC, etc.) to check for any fault codes there or network communications faults.

2003 mitsubishi outlander died at stop light. wont start. turns over and has a full tank of gas. is getting fuel to engine.


very poss it could be crank sensor ,broken wire ? timing belt? advise installing scan tool that reads live data check eng rpm on scan tool see if shows eng rpm while cranking , poss remove upper timing belt cover make sure is turning and not damaged, poss computer related problem or power to eng systems would have to check for power at fuel injs and check for ground pulse with logic probe or led test light if crank sensor ok also check for spark at plugs with special plug tester and check codes first

Was driving and check engine light came on than stopped and would only crank but wouldn't start


Yours sounds like the ignition module finally died out. That happens only upon driving and the engines dies completely and will not start. Check the fuel supply first before you run and buy a module for the ignition. You may not be getting fuel up to the engine also. One is bad so check the obvious first

times the starter will continue to run until key is turned off.
that is starter relay bad or the puter running it gone nuts.
or bad starter
next time when starter latches up, pull the relay
if it kills the cranking its bad relay or puter
if not, bad starter. all in 1min work..
and a very very serious first ORDER fix first problem
runs on test fuel. but you failed to keep it running for the 2 -3 second JEEP RULE.
if you had here is the results. (logic) hard.
1: i can keep it running with spray need a video?
yes, means ASD is not dropping out
2: no? ASD is killing the engine on purpose. and scan tool told you.

cranks no start
you said,
"No codes." if really true , there is no fuel pressure.!
if not true, its done wrong. so scan correctly THIS time.
is the skim light glowing in the dash cluster, if yes, it will not start
by DESIGN. SKIM is the immobilizer and DOES!

you must scan WHILE l its failing, not after, WHILE.
HOW TO SCAN correctly on JEEPS, (no starts)
key on, see scanner working? now, it must, if not ask.
crank or 5 seconds, (1 potato , 2 potata, 3,4,5.
release key, ( 4 and 5 are overkill but why not?)
do not turn key off or say 2 minutes, get PCM time to REPORT.

scan (2008 or newer scan tools work, CAN-BUS certified)
the tool then tells you why the ASD RELAY dropped killing starting (by DESIGN)
try to know SKIM is and option, so.... me blind can see car
http://jeepdied.com/ASD.html

runs on test fuel longer that 3 seconds, by hand, means.
all is working mostly, the fuel pressure gauge needs a jeep hose kit to work so/....... the pump needs power to work,



now the acid tests
i have 2. acid tests lacking a real scan too;..
spark timing light connected up.
you crank and spark dies, AFTER 2-3 seconds into crank/start
cycle means ASD dropped.
connect meter to injector 12vdc power feed its a daisy chain
12vdc dies, at 3seconds of crank, or dies
at 3 seconds of running,
if true PCM did that , and is ASD drop doing that
running any jeep for 1 second on test fuel is a waste of time
it tells too little
learn that jeeps can drop a ASD at 100mph
any time it wants. and only scanning while it drops
tells you why, unless the SKIM lamp glows,
