you can get pressure specs from your local parts dept, and check injector signal with a noid light

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

you need to check if you have spark as well if not, the crank sensor may have failed

Any one know 4by4 Mitsubishi triton no codes cranks need help urgent


the tachometer ( rev counter) get its impulses from the ignition system or in the case of a diesel from the crankshaft position sensor
if it runs with introduced fuel ( dangerous for a diesel) but then dies, that indicates insufficient fuel pressure to the injectors
could be a diesel pressure pump ( test to 25,000 psi) not producing sufficient pressure to work injectors
problem fuel supply to pump, tank venting, filters , air in system etc

1999 volkswagon jetta v6 cranks but wont start


I'm having a similar issue with my '97 Golf K2 with a 2.0 I checked the resistance to the crank sensor and it was almost 900ohms with the replacement one being 500 ohms. Changed it, didn't work.


Mine was running fine driving 70MPH on the highway and just shut off. Now it cranks, fuel pump runs and it seems to be getting fuel but still no spark. I have a coil/module on order and will try it tomorrow.


UPDATE

Replaced the coil. Coil sparks once when you first turn the key on, that's it. crank sensor has already been replaced yesterday.
Injectors seem to fire (I smell fuel if I crank it a while) but still no spark.
I have 12V to the coil and 12V when cranking.

I see tons of posts with this issue but no resolutions. Come on somebody has to have been here before....

UPDATE #2

I do NOT have an injector pulse or a pulsed signal to the coil. When I crank the car the oil pressure light blinks on and off (just noticed this not sure if it is relevant)

I do get a check engine light when I turn the key on and when cranking, thought this meant ECU was good?

Any other way to test the ECU?

Could the pick up in the distributor be bad? Doesn't the pick up signal the ECU to fire the coil and injectors, I thought the crank sensor was just a TDC reference point?

Car wont start but battery is good


"assuming" the engine is cranking normally then you need to identify what is missing

is the fuel pump running
do you have fuel to the injectors
do you have injector pulse

do you have spark

is the security module disabling the engine?

and finally what is the crank/cam timing
however, IF the vehicle is cranking normally then this should not be the cause

99 Tahoe engine cranks, wont start


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 63-64 lbs.
If you have all 3 then move on to injector pulse to all injectors.
I think each injector is on a separate driver on that one.
Check for pulse to all of them.

You may be weak on fuel pressure . even a couple of lbs low on a cold start will cause a no start.
Double check cold start cranking fuel pressure. If under 63-62 lbs you have problems.
one test is to give it a squirt of carb cleaner not starting fluid. If it starts then you have a fuel pressure problem.
Run the full fuel pressure test and post back pressures.
Here is the guide lines on testing.
Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
Later V6 and V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel.
Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.


The 75-85 is only a check on the capable full pressure of fuel pump.
If you can not find the rubber return line check full pressure by plugging return line or just or the true full pressure can be taken direct at the end fuel filter.
What are the pressure readings that you have done.
What are your cold start pressure readings?
Post back what you have.


The other thing to that is common is the (ICM) under the distributor cap. There is a breather screen on the bottom of the distributor that get's clogged with dirt causing condensation promoting corrosion, this was gm TSB for replacing the cap and rotor to make sure it's clean.

Good luck and hope this helps. Merry Xmas.

I have a 2001 camaro with a 3800 v6 it cranks but wont start. no feul and the injectors are not firing. i can jump the feul pump relay and get feul pressure but the injectors will not fire.


The crank sensor is what pulses the ijectors,and makes the spark,so I would start at the crank sensor.Let me know how you come out.Check for any blown fuses also.Ecm fuse would cause this,but it may be called anything ,so check all fuses.

Isuzu trooper starts briefly then dies


check your fuel delivery from the pump to the "dry" pulsing injectors leave the crank sensor alone! open the intake and, spray either (engine start) into the engine then attempt to start; it should start and, run until the either is used up then die. most likely your fuel filters are clogged

Have 99 sierra has spark and fuel to intake but wont start sometimes sputters but no go please help


You need to find out if you have enough fuel pressure, and if you have injector pulse. A noid light is a simple kind of test light that you can get at a parts house to test injector pulse. Unplug an injector and plug the noid light into the harness. Have someone crank the engine, if it flashes then your injectors are firing. Check all the fuses under the hood. You should have 55 to 60 psi fuel pressure.
