I am having trouble and need help! When the van has been running for awhile, It will not restart! It turns over fine! After Waiting for about 15-20 minutes it will re-start again. Any suggestions?

Ok so after it gets warm it will not start? Typicaly this means that some electronical part is making contact when it is cool and not when it is warm. This was common on lots of Ford products with an electronic module in the distributor. It is now common on GM vehicles with coil packs.

IMHO it might be you electronic module mounted to the bottom of your coil pack. Test it with the motor cold, IE see if you have spark. then after the engine is warm, test it again. You will need to test at least one wire from each coil (there are three of them). Good luck and I hope this helps.


Remember: Using used parts saves not only money, it also helps save the environment.

Same thing happened to me with my '94 Lumina APV. It does have the ignition module in the distributor. Had it tested a number of times and it looked fine. Finally failed just at the right time (mechanic driving it into the bay). Replaced ignition module and haven't had the problem in years!

I have had simular problems on 3 different GM's I've owned and it always turned out to be an overheating fuel pump that eventualy failed completly. the fuel pump is in the fuel tank and uses the gasoline as a coolant so never run your gas tank down to the low fuel light (about 2 gallons left) or you're just asking for problems.

What engine do you have? What you describe is typical of crank sensor failure, (though it could be something else) and has been described and solved like that in multiple cases in this forum and other GM forums. the pain to get to it is very different on the 3800 than on the 3.1. WIth the 3800 you must remove the crank balancer...but with the 3.1, just like my sister's Mazda 626 recently, it is part of the the ignition module in the distributor.
Check for spark when it refuses to go: remove one spark plug wire and connect another spark plug resting on the engine block to see if you still have spark...most probably not.

Ive had this problem with 93 & 95...replced 3 ign modules in 93. The 95 was a bad ground at the crank sensor. Ground comes from PCM. I grounded direct & has been good ever since..I verified this before & after with ohm meter though...you can pull the plug on your crank sensor...check for either voltage or ground to verify..
