Most likely fuel pump is out , It could be not pumping hard enough to get through the injectors. good luck

More than likely it's the distributor. They have a tendency to build up corrosion and rust and have personally went through the same situation three weeks ago on a suburban. Check to see if you are getting spark from the distributor first. Have the ecm in the distributor checked at Oriellys for free. It's under the rotor and has two 8mm head bolts with wires plugged in at each end.

SOURCE: my s10 will turn over, but wont squirt gas through injecter

Does it crank? Do you have any codes? Check engine light? Do you have spark? No spark check coil, and connections, also it would be nice to know what year it is. Get codes read. No crank check battery and starter. No codes or lights check crank position sensor, make sure your pcm is good after replacing your ignition mod you could have blown it if you did do it right. (engine computer) Check cam sensor if applies. Crank and cam could prevent it from starting and I know one I think cam controls pcm's fuel delivery on gm's

Do your switch turn over? You have to have the cover on top of the motor on before it will start!

SOURCE: 1997 Dodge Intrepid cranks over won't fire

I have this same NO START problem...
Began with tach giving readings not exceding 1200 rpm with strange 4000 + spikes.. Cruse control would not turn on or off at times and indicator light would only work sometimes..Had several episodes of excessive cranking to get it to start.. Stalling out while driving and even at freeway speeds.. Pulling the negative cable for 10 min. allowed it to start although with lots of cranking and put it in limp mode which required another computer reset to get out of.. Had thrown error codes related to cam and crank sensors which were replaced along with coil and manifold temp sensors.. Had the 9 volt power to sensors when key was on but the check engine light does not stay on with all the other idiot lights..
I wish people who respond would read the post first..
Original post states,
Cranks,No spark,No fuel pump run, changed some sensors ect...
If it cranks it ain't the neutral safety switch, starter or battery!! WAKE UP!!
Seems the computer is not turning on the coil, injectors or fuel pump for a reason.. Find that reason and you will find the solution to the problem.. Seeing as that the computers logic states are a dealer secrete the poster as I have changed many parts in blind hope that it will fix the problem.. Relays, sensors and ecu computer.. Did a visual check of all harness potential wear spots like where it crosses over the power rack..
Could it be in the wiring harness inside the dash??
Could it be a bad ground??
Can an alternator that has failed cause the computer not to start??
Can a bad oil pressure sensor cause the computer not to start??
Can signal loss from the TCU or BCU to the ECU cause this??
Is there an undocumented kill if the ECU thinks it was in an accident??
I can ground the relay line from the ECU and the fuel pump runs and pressures up and the other relays turn on as well..
This crank but no start problem seems to be common with a lot of 1994-2001 Dodge and Chrysler owners.. All these systems have become interlaced with undocumented safety features that baffle the DIYer..If you have seen this and have fixed it PLEASE RESPOND!!!!

My '99 chevy truck with 5,7L 350 will start but wont stay running. put new fuel pump and relay switch in

First you must determine if the fuel is stopping or the spark is stopping..If the fuel is stopping this could be a computer problem.. If the spark is stopping then it could be the IGN Module in the distributer. or any nomber of sensors. Squirt a little fuel directly into the Throttle body on the intake manifold.. If the truck runs longer its probably loss of fuel.. Do this several times to make sure, be careful and only use a small amounty of fuel.. you do not want a fire.. RE: Spark: Take a plug wire and an old plug..put the wire on the plug.. hold the plug against a good ground .. have someone crank the engine .. does the plug stop firing? The engine dies.. and will not restart for a minuet or so.. during this "no start" time do the plug test. If the plug will not fire during this time take the module out and take it to Orillys Auto parts.. They can test it.. really expensive part. Don't replace until you know it is BAD..

98 jeep put new crank sensor ' coil pickup' and coil ' i have no power to the fuse block on finder no fire to plugs and dont here fuel pump

No power to fuse block? This may be the problem. Check all your maxi fuses in the power distribution block. I think all the maxi fuses are hot at all times-check if they are getting power, and fuses are good.

Also in the power distribution center is fuse F15- a 30amp fuse for fuel pump relay, and fuse F6- a 15amp fuse, also for the fuel pump wiring. Check that both are good, and have power-F15 is hot at all times. F6 is hot in run or start.
This is the 4.0L inline 6, right? That is the engine diagram I have. The coil signal is from the ECU. Does the check engine light come on with key on, so you know the ECU is powered?

1994 CHEVROLET C1500 PICKUP 4.3L V6 vortek cranks no start backfiring thru the Throttle body fuel injection system. The Distributor has a small hairline crack under the reluctor wheel could this be the...

100 psi per cylinder is way too low--should be in the vicinity of 150-165 per cylinder
back firing indicates wrong firing order and as you have replaced the plugs etc check that you have the leads on the correct plugs in the correct order
the timing for the engine should be around the 10 degree btdc and not tdc

2001 blazer wont start ran fine before turning off has fuel pressure has fire check timming ok relaced coil ,ing moduel crank sensor dist cap could it be the anti theft ?

You say it has fuel pressure, if it has sequential fuel injection it needs about 70psi to start the engine.
If it cranks and has spark to the plugs, the anti-theft system is not involved.
You did not mention the rotor, I assume you have spark to the plugs not just out of the coil.
If you have not yet checked cranking fuel pressure, I would start there. The pump could be weak or the filter stopped up.

1/ Have you fitted the spark plug leads in the proper firing order.
2/ Look inside the top of distributor Top (this is not the first time a new distributer cap has very small crack) or the rotor arm is fitting the cap properly. Hope this helps Best Wishes, Malcolm Campbell.
