Question about 1992 Pontiac Sunbird

1 Answer

My sunbird stalled on me a few days ago while in normal operation. It would start, but not run for more than a couple of seconds. I thought it might be the fuel filter, but the next morning it would start but ran really rough. I changed the fuel filter but it still ran rough. A friend suggested it might be the fuel pump. I tested the pump pressure and discovered the fuel wasn't under a lot of pressure, only a trickle. I changed the fuel pump, but with a used one. No change in the running of the vehicle it still runs rough. Could me problem be and power to the sparkle plugs or perhaps the computer?

94 jeep grand cherokee stalls after the first 5 min of operation


Sounds like the automatic choke is either binding or gone bad.

On a cold start, that's why the RPMs are bumped up for a few minutes...the choke is allowing the engine to warm up, before dropping the intake mix to normal "run" level.

However, should the choke remain closed once the engine is hot, the stalling will happen for lack of air.

The choke-control is mounted on top of the manifold, near the throttle cable-cam.
Look for a small (about 3" wide X 2" deep) cone-shaped metal can with a linkage to the throttle cam.

With the engine off, spray the linkage at both ends with Liquid Wrtench and work the linkage in and out of the can a few times to check for smooth operation.
You should feel slight back-pressure when you move the linkage toward the controller.
With the linkage pushed in, spray and wipe the exposed surface inside the controller body.

Allow the cleaner to dry for a few minutes (it's just oil, I know...but if you used a spray, the propellants could be flammable) and start the truck.
Allow it ti idle at least 5 minutes until the auto-choke pulls back on the throttle...then take a short ride around the block to see if that cured the stalling.

I think your problem might be your fuel relay which is situated next to the fuse box in the engine compartment.

Hard starting


check the battery cable connection that is sandwiched between the battery and the outside cable, It runs the computer and if it is corroded, clean it with sandpaper. Mine was loose and corroded and I would stall out of no where.
