Question about 2000 Chevrolet Monte Carlo

1 Answer

2000 chevy montecarlo 3.4L, Engine cranks but dont start.

The fuel pressure is 50-60psi. The fuel injectors are spraying. Checked spark plugs and regapped. They do spark. Changed the IAC. Checked all fuses and relays for ignition and fuel systems. I cleaned the mass air flow sensor. One thing that didnt make sense to me is that I sprayed brake cleaner to the intake manifold and it would not **** in the brake cleaner it sat there.

Hook up vac gauge and test cranking vacumm should be at least 3 to 5 inches while cranking if not suspect plugged cat converter or timming jumped also check compresson that will tell you whatz up .

If you have spark at all the plugs, the crank sensor should be ok. You should use a gage to check fuel pressure? I don't know engine size? For the 3.1L engine, my info says 40--46 psi.
It is possible to have spark at the plugs, but, the computer doesn't see rpm signal. If that is the case, no fuel injector pulse. The purple wire with white tracer carries rpm signal from ignition module to pcm, that wire has dc pulse, engine cranking. If nothing there, have to check ignition module.
How long since a tune-up? Any applicable trouble codes?

Fuel injector spraying too much fuel


Excessive cranking will put too much fuel into the engine. Have you tried holding the gas to floor and see if it starts. That will help clear out excess fuel from continued cranking.
Check for spark at a sparkplug wire. This will tell you if ignition system is working. You need to see a blue snapping spark to know ignition is good. If you are not sure how to check for spark, have someone help you. Easy to get a shock when checking for spark. You need the metal end of the plug wire just 1/8 inch to 1/4 inch away from a metal bracket or bolt on the engine. Hold it steady while someone cranks the engine over-watch for a strong blue spark to jump from metal end of wire to the engine. If no spark, your ignition system needs checked. If spark is good, have the fuel pressure checked-maybe it is getting too much gas.

listen for fuel pump when u turn key to on [not start] should hear a hum-check for pressure at fuel port -if pressure need to start checking sensors a bad crankcase position sensor--camshaft position sensor --bad egr valve--can shut down and not allow start those components sometimes dont throw a code

My 2004 yukon xl wont start


You need spark at the right time, fuel pressure at the injectors, and normal compression.
Have the spark plugs been changed in the past couple of years ?
Have you checked the fuel pressure to see if it is enough ?
Have you sprayed carb cleaner into the throttle body to try to make the engine try to start ?
Does it sound like it has normal compression when cranking ?

2003 vibe will not start


It has good spark then? Have you pulled a plug or two after prolonged cranking to see if plugs are wet with gas? You said pump was working, have you checked the fuel pressure? Nothing in your comment about the injectors-that's why I asked if plugs were wet.

Check the fuse for injectors, verify that power is available at all injectors with key in ON. You can check the injector circuit with a "noid light" available at any parts store-different sizes, so get the one that fits your injector connector. Just plug the light in and crank the engine over. If circuit is good, the light will blink. If it doesn't blink or if it lights up and stays lit-the circuit is not right.

All of this is to see if injectors are pulsing and spraying fuel. Do the same with spraying starting fluid into the air intake and cranking motor. If engine now runs for a few seconds, then you know it was a fueling problem.

If you are getting spark and the engine tries to run on starter fluid, then you have lost fuel. Check that you are getting injection pulses at the injectors and check the fuel pressure at the fuel rail at the injectors. Check for power to the fuel pump when the engine is cranking, If you get no power to the fuel pump when cranking the engine, check fuses and relays. If the pump is running but you have no fuel pressure, check the fuel filter and fuel pressure regulator and replace any that are faulty. If the injection pulses are missing, check the supply relay which supplies power to the injectors first ( the injectors are earthed by the ECU) Disconnect one of the injector plugs and using a test light (buy one from a auto parts store) clip the end to a good earth on the vehicle body, switch the ignition on but dont start the engine, then probe the two connections in the injector plug. One of these connections should be active all the time with the ignition switched on. If it is, you may have a sensor failure (crank sensor etc), if it is not, check fuses and supply relays. A word of warning, the wiring you are dealing with is connected directly to the engine control, if you make a mistake, you can cause irreparable damage so if you have any doubts, take the vehicle to a professional..

1997 Chevy Silverado 1500 4x4 will not start. Getting spark checked all fuses, changed rotar - spark plug wires,


Have you checked the fuel pressure? Fuel pumps are a common failure item on those trucks. Pick up a cheap fuel pressure gauge and hook it up to the shrader valve on the fuel rail. With the ignition on and you should have 55-65psi. Even if it's a few psi below spec it could stop the engine from firing.Once you determine the fuel pressure isn't adequate make sure you have a good power and ground at the fuel pump. If that checks out, time for a new fuel pump module. I recommend only replacing it with an AC delco unit, I've heard bad stories about aftermarket replacements.
You could also spray some carb cleaner or starting fluid in the throttle body and crank the engine over. If it runs for a few seconds after spraying starting fluid in you know you have a fuel delivery problem.
