1995 Bonneville: i have 1995 pontiac bonneville fuel all the way to...

Do you have a security light lit on the insturment cluster ? Check engine light etc.... Could be a lot of thing's , testing should be done . Fuel pressure testing using a fuel pressure gauge , before replacing parts . If do not know this , do yourself a favor , take it to a qualified repair shop . Would cost you less in the long run.

Replace your fuel filter and check the fuel regulator for proper p[ressure to the injectors.

crank position sensor...if the engine will start and run for a second or two then it dies. If, however, you can press and hold the gas pedal slightly and keep the engine going, then I would suspect the IAC-idle air control valve. This can be cleaned with spray carb cleaner.

do your have injector pulse (will need to puchase noid lite to check)

WOW a 94 with 46K on it thats rare. Your computer may be bad it sends the pulse to the injector.

my pal jojo had this problem just 3weeks ago and his fix was plugs and wires.hope this helps.

For the fuel injectors to pulse (open and deliver fuel to the engine) they need a command from the computer. The computer gets information/signal to operate the injectors from the ignition module. The ignition module receives its information from the crank and camshaft position sensors. For the computer to pulse the injectors yet the engine is not running indicates there is an erratic signal being created. About the only way this can happen is if there is a bad ground wire. The computer, ignition module and sensors rely on a good power supply to operate. But more importantly these systems require a good electrical ground. There are several ground wires that are dedicated to these components. Failure of just one of these wires can send the system into total chaos. The result is a confusing condition much like you’re describing. Prove the condition of the grounds and you’ll likely be up and running again.

the cam and crank position sensors are common failure items that would cause these symptoms

When was the last time spark plugs and wires where done? That could be a possible cause, also check the timing through the distrubotor cap.

Hope this helps

Unscrew it and replace the "O" ring at the fitting. These "O" rings like to get old and crack.
