The security system will keep it from turning over on that model. You need to try a 30 minute theft learn. Follow these instructions closely. Try to start the car, then leave the key on for 10 min. Turn the key off, 2 or 3 seconds. Turn the key back on, do not try to start the car this time, leave the key on for 10 min. Turn the key off again, turn it back to run, do not try to start it again, leave it for 10 more minutes. Then turn it off, and then try to crank it. If it is a security problem and it is not the ignition damaged it will crank. Good Luck. Mike From Texas.

Mr.Beckett. I just read your questio. My Advice for this issue is: If you have any experience on mechanics, just clean your Throttle body, from dirt oil mud sad on the edges where the accelerator plate works. For a better job if you can remove it for cleaning. I have to inform you if your throttle body is electronic one just leave the work to the specilist mechanic of yours. If it is a mechanical one clean it but always carefully. Best of Luck.

Could be any of several things but most likely to be fuel starvation caused by anything including a foreign body in the fuel tank, tank breather, weak fuel pump or semi-blocked filter. Lots of checking which might not reveal much due to needing to drive a couple of hours before the problem happens.

Under passenger side of dash down by the kick panel. Remove battery cables before disconnecting the ECM. Then remove the connectors from ECM.

Check for a sticking torque convertor solenoid/clutch causing the transmission to stall the engine just like a manual trans would do if you never pushed in the clutch pedal. You can disconnect the valve body round wiring connecter going inside the trans and see if the problem goes away... Hope this helps

Sounds like a bad fuel pump or fuel regulator also cold be spark plugs if occursthe worst when it cold

Gray is the B+ power for fuel pump , black is ground for the fuel pump ! The other two wires are for the fuel level sending unit .( gas gauge )

I have a 94 buick park avenue ultra for 3 yrs. and it started stalling out. Going on line, some people replaced most sensors and gas filter. My problem was vacuum lines that were shot and one, going yo the fuel pressure regulator wasn't connected, which was the main problem.
