If your car has spark and runs on starting fluid you have a fuel problem not a cam sensor. 41 lbs of fuel pressure is not enough. Try pinching off the return fuel line and check the pressure. Let me know what you find.

    If the fuel pressure is still 40 pounds than you fuel pump is junk. When pinching the line the pressure should jump

    I will lok up the fuel pressure specs tonight and post them tomorrow

  • mikehumble Dec 18, 2008

    And why are you unplugging the cam sensor?

  • mikehumble Dec 19, 2008

    One other problem these cars had is a bad fuel pressure regulator. Pull the vaccuum hose off it and see if there is gas inside the hose. I am still trying to find the fuel pressure specs. I usually get them out of my scan tool but it does not have them for this car.

    Have you fixed it yet and if so what did you find?

2002 Chevy Avalanche 1500 5.3 will crank but not start. Changed cam crank sensor fuel pressure regulator and got 52 pounds of fuel pressure


Why did you replace cam , crank sensor's an the fuel pressure regulator too ? What is or was missing ? fuel or spark ? did you pull a plug wire an check spark . Does the check engine light ,light when the key is turned to the run position ? Do you have a professional type scan tool ? Do diagnostic's ,not guessing an just replacing part's .

1991 Pontiac Firebird Starting Problems


probably lost spark or gas when it gets warmed and wont restart.

Do these two tests when it acts up: test the fuel pressure with a fuel pressure gauge. I believe you can rent them at Autozone. You don't have to start the engine, just hook up the gauge, turn the key to on, and check the pressure. It must be within Pontiac (GM)specs, which for multiport injection is pretty high around 40-45 psi. Parts stores can look it up for you, I believe.
Also pull a spark plug wire and check for spark with engine cranking over. The easiest and safest way to do this is to buy an inexpensive spark tester. The plug wire fits over the tester, then you clip the tester to a ground, like a metal bolt or bracket on the engine. Verify there is a strong blue spark- if not the ignition system must be diagnosed. Cam or Crank sensors are often the problem-the engine computer uses them (especially the crank sensor) to determine spark timing. If sensor malfunctions, you will get no spark.
You should also check for trouble codes. Post back if you don't know how. It just takes a short jumper wire or paper clip to have the codes flashed out by the check engine light.

The car will not start. the engine turns over but will not start i have spark and gas... 3.4L 1994 firebird


1.= HOW MUCH FUEL PRESSURE DO YOU HAVE?
YOU NEED AROUND 30 TO 45 LBS.
2.= MAKE SURE YOUR FUEL PRESSURE DOES NOT DROP RAPIDLY AFTER YOU SHUT YOUR KEY OFF.
IF IT DROPS REPLACE YOUR PRESSURE REGULATOR.
3.= YUOR PLUGS COULD BE FOULED TOO, IT HAPPENS.
IF YOU DO NOT HAVE ENOUGH FUEL PRESSUR THIS WILL CAUSE YOUR INJECTORS TO RUN RICH.

Ensure you have spark first, if confirmed, you do not have FUEL !

MUTIPORT FUEL INJECTION PONTIAC FIREBIRD 3.1


My 92 Bird with the 3.1 did the same thing after it sat for about 2 months. The car had aways started right away before. I had to jump start it and I thought it would never start.Same as yours after it started. Seem to get better after I ran it awhile. It was getting good spark and was getting fuel. I checked fuel pressure, it seemed to be within specs.then it started to sputter and the pressure dropped to almost nothing. Seems that the fuel pump was going bad, but still would pump enough fuel at times to run. When the car was parked the fuel pressure would bleed off, and when I tried to start it the pump had trouble pumping enough fuel to pressure the system.Long story short! Replace the fuel pump, and filter.....
