SOURCE: 2000 buick lesabre stall after starting or after running for 30 minutes

I have a 1996 Lesabre. I had a similar problem that slowly got worse. I brought it to two different mechanics that did diagnostic checks and could only "suggest" what to replace to fix the problem. Their problem was that it wouldnt stall out while they had the mv. After replacing a bunch of sensors and the fuel pump/ filter, I solved the problem by replacing the Crank Sensor. Its located behind the lower crank pulley on the 3.8 lt motor. Hope this helps!

SOURCE: 1990 Buick Century 3.3L Check Engine Light comes on, stalls.

Need to check for fault codes. Possibly a faulty sensor causing the fuel system to run rich or lean.

SOURCE: I have a 1987 Buick Century. That stalls out

I'm not Roger but can tell you this....if you have a bad crankshaft position sensor or a corrupt ECM....your car will do that.....last things could be the timing belt.

SOURCE: I have a 1990 Buick Regal that stalls while

most likley a fuel pump issue. The only way to know for sure is hook up a pressure gauge and when you have symptoms check the pressure. If you spray some brake cleaner or quick start when it doesnt start and it does start then this is an indication of a failed fuel pump or fuel pump relay. If it still does not start when you spray then you have an ignition issue like a crank sensor or ignition module.

My 1996 Buick Roadmaster LTD engine intermittently stalls.


U DON'T HAVE A CARBURETOR SO FORGET THAT, THE FUEL REGULATOR WOULD NOT CAUSE THIS PROBLEM. I AM A GM FACTORY TECH AND KNOW THIS WITH CERTAINTY. U COULD HAVE SLUDGE IN THE IDLE SPEED CONTROL AIRBYPASS VALVE.

92 Honda Accord has intermittent stalling


Hi,

Hey, good job ordering the "main relay" honda have a BIG problem with this issue. That sounds like your right on target. Some other ideas to kick around if that doesn't work.

1. Clean the throttle flap

dirt get on flap restricting air flow causing stalling issues. (Clean with B12 cleaner in the white can and a rag. Don't use too much B12 cleaner. 10 seconds is more than enough. )

2. Check Idle Air Control Valve
check the Idle air control valve on the back of the intake manifold ( firewall side on engine) remove the two bolts and inspect the screen in the valve for dirt and carbon. You can replace it, but it just may need to be cleaned.

Good luck with the project and hope I'ved helped.
