Oldsmobile Silhouette Stalls and Won't Start

Unread post by Kenny » Mon Feb 15, 2010 12:14 am

1994 Olds Silhouette 3800 3.8 engine Mini van 3.8.
My friend had the fuel pump changed and gave it a standard tune up.
Hello Guys.
My friend recently purchased a use 1994 olds mini van Silhouette with the 3.8 engine its a very clean car and runs great but after awhile for no reason it dies out and has a hard time restarting ? he had a standard tune up done and new fuel pump installed. it ran great for a few days then started doing it again dying out ? Another friend said to ck or change the mass air flow sensor ? I think its in the brain or control modual myself ? Has any of these issues popped up on these vans before or do you know where we should ck ?
Thank you.

No, it would not be the MAF sensor. That would cause a stall or hard to re-start.
Need to find out what it missing when it stalls and wont start.
Is it missing fuel pressure, spark, fuel injector pulse?
Assuming fuel ressure is good, then find out if loosing just spark or injector pulse is the key.
Is missing both, then it could be crank position sensor or ignition module.
If just missing fuel injector pulse, then may be a PCM. Would need a "Noid" light or test light to check injector pulse.
A way to test the crank sensor is to tap on it to see if you can get the van to stall, or is to poor some water on it to cool it off after a stall, then see if it starts back up right away.
The crank position sensor is behind the crank shaft pulley.

Well, that's really hard to say without hearing it. It may be the warning chime is going off for some reason- like the seatbelt is unbuckled, but the chime is just broken. The chime is internal to a module.

Try turning the van off, then turn on the headlights. This will cause the chime to activate. If it sounds funny like that, you can determine that the chime is broken, but will still need to find out why the chime is activating in the first place.

here is a picture for some sensors on the engine. Why are you looking to replace the sensors for an overheat problem?
