No fuel to injectors


John,
Probe one injector to see if you are receiving voltage pulse as you crank the engine to narrow you problem area. You can test if it is a fuel problem by a squirting a small shot of fuel into the throttle body.

1997 chevrolet suburban with 7.4 engine will not start after being turned off without waiting 10 minutes.


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

Wont start it cranks but nothing happens.wont turn over. put a new what you would call distributor. still nothing.


If the Starter isn't turning the engine over, but you hear a clicking sound, you may have a bad Starter.
If the Starter is turning the engine over, but you are getting no Spark, you may have a failed Camshaft or Crankshaft Position Sensor, or your Timing Belt may have jumped or broken(common on the neons).
If the Starter is turning the engine over, but you are getting Spark, you may have a failed fuel pump, fuel pump relay, or fuel pressure regulator.

Before you start replacing sensor, double check the Timing belt to ensure it hasn't broken or jumped, and check to see if you are getting a spark or not.

I have a 1987 fiero gt with a 2.8 v6. After setting for a winter, the car would not start. Fuel pump wasn't running, so I replaced it and it now pumps but still car will not start. Removed and cleaned...


You need to do a little detective work here. Based on your question it appears the engine is not getting gas. You changed/cleaned the injectors, yes. Do you test them somehow to see if they were actually squirting fuel. In the injector system the fuel pump fills and holds constant pressure on the fuel rail. The injectors get their fuel from the rail and an electric pulse causes the injector to open for a split second to shoot fuel into the cylinder. If you have the right tools you can test the fuel rail pressure to see if the pump is actually delivering fuel and pressure to the injectors. If so, you need to verify that the injectors are being electrically "turned off/on" to squirt fuel into the cylinder. Usually you can hear them clicking when the engine is turning over before it starts. It will be clicking pretty quickly but you can hear it if you get close. You can also put a screwdriver (big one) by your ear and touch the metal end on the engine near the injector. The screwdriver acts as a poor mans stethoscope. Try it it works, just be careful you don't touch anything electrically charged! My thought is that the fuel pump and fuel delivery system is not getting fuel to the injectors. Could also be caused by a dirty( maybe plugged) fuel filter. You said the fuel pump was not running, that should be a big clue to the final problem. Look for fuel to had dried or jelled when the car was sitting. Fuel doesn't stay in good condition very long and the injection system uses very small ports so they can become clogged pretty easily. hope this helps, good luck, worm1855

Will not turn over already changed the fuel filter and the fuel pump was changed two years ago its fuel injected. battery is fine and so is spark plugs


fuel rail, injectors, of possibly the max fuse in the underhood fuse box that powers the fuel pump. see if you turn the key to accessory if you can hear the fuel pump. and if it is getting fuel test the plugs and wires.

I have a 1987 2 wheel drive suburban 5.7 v8 and I just stopped a signal light and it died. I put it in park it started right away and when I depressed the brake and tried to engage it to drive it died...


No. It is either a fuel or ignition problem. Check for spark, and then fuel. Your filter could be plugged, or fuel pump may have given out. I assume it's fule injected? You should be able to hear the pump cut in for a couple of seconds. If it's carburated , just take the breather off, and pump the gas a couple of times. You should see gas squirting in the carb.
If there's no spark, check wires, distributor, etc.

1997 chev. suburban new fuel pump and regulator WILL NOT START


Check fuel pressure and fuel flow, If the pressure is lower than what is recomended injectors will not function correctly , no start condition (trys real hard though)

I have a 1995 Chevy suburban, and I'm trying to figure out why is it when we go to start the truck it churn and churns, so then we dump a cap full of gas in where breather is before it actually kicks off....


have you checked your cold-start injector? these injectors will just deliever one "squirt" of gas into the intake when starting the vehicle - much like your cap of gas down the breather does...
