Fuel injector/timingbelt I was told that my fuel injectors where damaged because the timingbelt was not properly. My question is, what has the working of the fuel injector got to do with timingbelt. 2000 mitshi spacewagon

Silverado 1500 or 2500 or 3500 or HD? no pickup told
not told the job you are doing>??
remove them all ,or scope them or just what, no job told
no end goal or task told. sorry can guess it.

like most V6/8 now , it is a sandwich.
the service manual covers all,l buy it rent it.?
toss dice and land on 1500
the rail on this engine, fuel rail like all , intake manifold injectors used;. all injector held down by both rails. left and right
now the steps to off them if is the job,
pull the isolator seen photo 1, far below.
1: pull left rail and right rail
Remove and discard the fuel injector retainer clips by installing EN-51097 injector retaining clip installer and spreading both sides of the clip evenly.
Always use NEW fuel injector collars supplied with injector when installing the new injector. If reinstalling the injector, it is not necessary to remove the collars unless the collars are being replaced.
Replace the injector seals as needed. Refer to Fuel Rail and Injectors Cleaning and Inspection.
Note
Inspect the injectors to be sure that they are clean and free of debris prior to installation. Do NOT lubricate the injector seals. Rebuild the fuel injectors whenever the injector has been removed from the fuel injector rail.


now I will past the other page rails off per the manual read to you.
just bank 1, i am to lazy to post both
step 1 rail off bank1.
Note
Inspect the injectors to be sure that they are clean and free of debris prior to installation. Do NOT lubricate the injector seals. Rebuild the fuel injectors whenever the injector has been removed from the fuel injector rail.

1. Remove the fuel pump insulator. Fuel Pump Insulator Replacement
2. Remove the fuel injector intermediate pipe position?1. Fuel Feed Intermediate Pipe Replacement - Position 1
3. Clean the cylinder head pocket around the injectors of any dirt or buildup.
4. Disconnect the electrical wiring harness connectors from the fuel rail.
5. the fuel rail fasteners are retained in the fuel rail by keepers and may be difficult to remove.Remove the fuel rail fasteners?(1) securing the injector rail?(2).
   Install two sets of EN-49248 remover?(3).
6. Install one remover in each of the fuel rail fastener bores.
7. Remove by turning each section of the EN-49248 remover an even amount to pull the fuel rail and injectors out evenly.
8. CAUTION
9. Remove the fuel rail assembly carefully in order to prevent damage to the injector electrical connector terminals and the injector spray tips. Support the fuel rail after the fuel rail is removed in order to avoid damaging the fuel rail components.
10. Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering open pipes and passages.
11. 1. Simultaneously lift both ends of the fuel rail?(2) and remove the fuel rail assembly from the cylinder head.
12. Remove and DISCARD the fuel injector seals.
13. Some vehicles were not originally equipped with fuel injector dust seals. A NEW seal must be installed when the injectors are removed.
    Remove and DISCARD the fuel injector dust seal (1).
14. NOTE
    Note
    Whenever the fuel injectors are removed from the cylinder head or fuel rail, they will need to be rebuilt. Fuel Rail and Injectors Cleaning and Inspection
    If replacing the fuel injection fuel rail, remove the fuel injectors. Fuel Injector Replacement

Installation Procedure, skipped me. the service manual lists 4 tools
per

Special Tools

1. EN-49248 Injector Rail Assembly Remover
2. EN-51105-1 Injector Seal Installer and Sizer
3. EN-49245-3 Fuel Injection Seal Installer Sizer
4. EN-49245-4 Fuel Injection Seal Installer Sizer

this is first. pull the isolator.

this one step is the GET TO ANSWEREd
Injector work 10x more complex and special tools needed x4

low miles for age, a USA car? ENgine told at all and is and engine EFI problem.
5.6L V8 engine????????? NISSAN
all fuses tested good, skip NONE.
scan show not one DTC error right>?
no starts have 50 causes. guessing is super expensive and invites big time adding 2nd or 3 problem from just 1.
not old are all injectors bad? or just 1.?
the PCM fires the injector, and cuts them all for many reasons.
you did not scan the PCM after the no start event>?
all car parts stores sell injectors. uses and new and rebuilt.
I send them out for reverse flow ultr sonic cleaning,
they have 10 micron screens inside so must be reverse flow cleaned
so the engine starts and runs on spray instant start in a can?
3sec blasted to intake and runs for 3 seconds and the enigine sounds good try it 3 times to be sure that????????????????
if yes, we do check 2 or more things.
we use NOID lamp to see if all injectors pulse x8
or scope tested any scope works
and check injector pins for ohms good $15 dmm meter and bingo all are same ohms. 15ohms is common.
fuse 55 powers all injectors here, daisy chained.
the PCM drives all injectors (low ) with on board, PCM drivers.
there is no such thing this Injector pulse module at all , like we say in early 1990 or late 1980s, sorry NO SUCH THING
am not arguing names but the PCM runs all 8 injectors ALL BY ITSELF for sure.
nos scanning the PCM is a huge error. what if you had dtc codes for shorted open injector coils.
the PCM has 122 pins on 3 or more connectors
if input to the PCM are wrong he PCM cuts fuel.
if the PCM detects spark is hard dead, the PCM cuts fuel to prevent crash and burn as seen on TV (jive)
the PCm cuts fuel if any cmp or CKP sensor dies
see why I asked if all injector pulses are dead
and the p55 fuse is hot key on as are all injector pins hot key on?
the PCm cuts fuel also for IMMO failures of ANY KIND
the PCm cuts fuel for SRS system crash detectors tripped.
the PCM cuts fuel for any gross error of TBW.
THROTTLE BY WIRE HERE, IF SAY THROTTLE TV VALVE MOTOR STICKS OPEN IT FOR SURE CUTS FUEL DEAD.
F22 FUSE BLOWN GEE KILLS THIS TBW DEAD.
NO MORE DRIVING OVER KIDS NOW. OR 1BILLION $ LAWSUITS. AS TOYOTA SUFFERED AND WAS NOT THEIR FAULT AT ALL.

IF YOU WANT TO DO DIY, YOU MUST HAVE TOOLS.
A REAL SCAN TOOL
A FUEL PRESSURE GAUGE
AND ANY CHEAP DMM. $15 UP.
IF ALL INJECTORS ARE DEAD SAY SO.
IF ONE IS DEAD REPLACE IT OR CHECK OHMS FIRST.
IF NOT SAME OHMS AS OTHERS THERE IT IS BAD. FOR SURE.
IF ALL ARE DEAD NOW YOU KNOW WHY THEY ARE.
CUZ I TOLD YAH.


LEARN NOT TO GO TO STEALERSHIPS AND FOR SURE WHEN SUPPORT IS ZERO. !! WOW WHY BUY NISSAN? GO JEEP.
ANY ASE SHOP IN THE USA CAN DIAGNOSE THE CAR AND NOT WAX LAME LIKE THE DEALER DID.
PULSE MODULE LIES TOLD TOO.
POWER-TRAIN CONTROL MODULE IS IT.

I use SMP a top maker,!!!!!!
injectors are not some rarity ever. huge huge industry support.
case in point not RARE AT ALL.
AND REBUILTS AND LOST OF SHOPS THAT DO ONLY INJECTOR CLEANING LIKE NEW.
AND WILL TELL GEE INJECTOR 4 IS NOT GOOD.
IF IS,.

WE SCOPE ALL 8 LOOKING FOR BAD WAVEFORMS
THEY ARE IN FACT PWM , MODULATED TO KEEP THEM COOL
A WHOLE OTHER LONG TOPIC SEEN STICKING INJECTORS ON A REAL SCOPE. I CAN EVEN SEE THEM OPEN? ON THE SCOPE
IF ALL DO FIRE RAIL PRESSURE TESTS ARE NEXT.
OR EVEN FIRST.
FUSE
SCANS
FUEL PRESURE
AND TEST ALL INJECTORS FOR CORRECT PULSING
IF ONE IS DEAD JUST SWAP WITH ADJACENT INJECTOR
NOT FLEX FUEL ENGINE NOT E85 RIGHT>
THE BOSCH INJECTOR DOES ALLOW E100
62640 STOCK INJECTOR (FLOW RATES) DO NOT NEED REPROGRAMMING ANYTHING.
THE COILS ARE 12-14 OHMS
0 SHORTED COIL
INFIRMITY I BURNED UP COIL
24 OHMS IS COIL DAMAGED.
WE JUST BE SURE THEY ALL READ ABOUT THE SAME 12.
I ALSO HAVE A NICE SONIC INJECTOR TESTER THAT HEARS THE INJECTOR CLICK PROPERLY.
NOID TESTS
SCOPE TESTS
SONIC NOISE TEST.
KEEP IN MIND THE PCM HAS HUGE FET TRANSISTOR TO DRIVE THE INJECTOR AND HAS 2 FAILURE MODES ANY SCOPE SEES IN 1 SECOND FLAT
1: DEAD DRIVER
2: WEAK DRIVER ,OVERHEAT DAMAGED.
OR 12VDC POWER ON OTHER PIN IS GONE, THE DRIVER SEEMS DEAD. AND IS NOT.

Well depending on what it is. Most of the times you have 2 banks. Banks 1 and 2. Each bank controls 3 injectors each. When one injector is bad, usually shorted it shuts off the whole bank to protect the engine

Opel Corsa bakkie 1.7 dti , NO YEAR TOLD! WOW HARD. in AFRICA?
fuel tank empty
OR gauge fuel lies.
or level sensor bad and lies.
some cars if oil pressure is dead it cuts fuel.
fuel is bad and or is water soaked,
fuel filterS bad.
fuel injector pump BAD (No year impossible answer)
FUEL PUMP BAD, OR NOT PRIMED.
GLOW PLUGS DEAD.
yes i can be any of that'
and more,
does spray test fuel work to engine intake? by hand.? work? (short time)?
check all fuses first so glow plugs work?
engine compression ok if test fuel test fails?

only remove fuel injectors after you have properly marked all the fuel pipes for what cylinder to go to (it matters!!) also carefully bleed off high pressure fuel from lines before removing them all the way (watch your eyes!!) use only a six sided socket to remove fuel injectors or you may damage them , try to avoid using an "IMpact" gun to remove , and allways reinstall with using a torque wrench to assure proper tightness , make sure you get fuel lines back exactly on new injectors exactly as you took them off , its also a good idea to replace glow plugs if equipped at same time

Never heard of what your saying

You were told something you don't understand
about drive cycles & if they are required a shop
is to look up that procedure & do it for you before
giving you the car back

They don't know what their doing ,period

Your car was not diagnosed properly for your original
drivabiltiy complaint

They may have found & replace something that wasn't
as it should be, but it should have run as poorly for them
as it does for you,should it not

If that was a dealer,they may have never road tested it

There are no drive cycles that require any miles to relearn
& no relearn for an injector

Need to get back to them on what you were told,but your
not responsible to drive any distance,pure nonsense &
sloppy work & untrue advice

What test told you it is not firing?

You may have valve damage &
little compression

You can try the fuel cleaner but more then likely, it is something other then that. Check the fuek pump and make sure it is working correctly. Test the wires. It should be 12 V. Follow the line down to the fuel filter and check that. Make sure fuel is getting to the filter. The filter may be clogged. If that checks out, follow the gas lines down and make sure there are no leaks or damage. Next, move to the injectors. Make sure they are working properly. Check the fuel regulator as well. You should find your problem at one of these points. If you have a question, let me know. I am here to help in anyway I can. Thanks for choosing FixYa.

Have you replaced the spark plugs?? Use good plugs such as ngk. Look for signs of carbon tracking on porcelain (black dirt looking marks that can NOT be wiped off. If present replace spark plug and coil boot to repair.

I have been told on some cars that the cam sensor provides the pulses for the fuel injection. Hope it works for Ya!!
