1992 olds royale, suddenly shuts down while

87, ouch old iron.....
which engine?
is it a CARB? engines.
ever tune it up, fully? if not why not.?

A loose or bad ground could cause this problem. Also loose connections on Positive cable

Hi,
Get your Automatic Transmission Fluid (ATF) checked, it could be old or low. May be time for Transmission flush, too.


GL,

Sounds like a bad starter. When a bad starter is cold, it will still start the car. Once warm, the starter requires more power to engage. Eventually, the starter will fail under all conditions but from what you describe, it certainly is showing all the signs of a bad starter.

DO you have any engine codes still remaining? IF car restarts right away its gonna be tricky finding out what is dropping out. Engine codes are the best clue to start the hunt for problem. From experience however, I have had a few of these come in for same symptom. There are two wires that run from Ignition module/coil pack to the crank sensor, insulation falls off and they melt to each other or to hot engine, intermittent short disruption of signal, hence car stalls whenever wherever and restarts right away.

We had this same problem. It turned out to be the computer. We had the computer replaced and it worked great for awhile but now there's something else wrong with it. Hope this helps and good luck.

Try turning the key to the on postion-not crank, just to he postion right before cranking. leave it in that postion for 15 min, Do this three and after the third time go ahead an try to start it. Hopefully this will reset your security for you.

I may not be the fuel pump, it will be an ign-module or cam/crank sensor defecting.

could be a transmission problem which is stalling the car when stopping had a van that used to do it and it was a sensor controlling the transmission also could need just a simple tune up plugs wires ect

It sounds like you have a clogged fuel filter or the fuel pump maybe weak. I would change the fuel filter first and see what happens. Or you are having a distributer problem with the coil. Also check for a wire grounding out around the engine.
