90 Lumina APV Stalls

I need some help. I have a 90 Lumina APV 3.1L. The problem is when I drive for long periods of time and turn off my van I cannot start it up again for at least an hour. Now it has taken to stalling out at low excelleration. IE: Turning a corner, or at a stop light. When I try to start her back up again she wont turn over until I wait for a half an hour. No codes or engine light on. I have replaced the starter, fuel pump and now this. Any help would be appreciated.

I had that same problem FOREVER. After lots of speculation, and even having the ignition module tested for a long time, van finally died while at the mechanics on the scope. Turned out to be the ignition module in the distributor after all. Apparently not uncommon but first time for me. Problem has not recurred for over a year now! Good luck!

Yes. module or pickup coil.

Hey Watso! What happened! Is it fixed?

I agree with the Jeffs, it's either a module or pick-up coil.

Well we changed the plugs. Seemed fine for about a week. Then it started stalling out on me again. However usually after a few min I can restart it up again. Its almost like the car is flooding out. Going to try what you suggested. This is the weirdest damn thing. No problems before the new starter and now the car wont friggin start if its too hot. I have to wait till it cools down

hey can you give me an easy way to change the modual?

The module is under the distributor cap. Once the cap is removed, two screws, two wire harness connectors, and it's out. Put some dielectric grease (it should come with the new module) on the plate under where the module mounts and screw it back down. If you have a digital multimeter, you can test the pick up coil while the cap is off. On one end of the module, there should be a 2 wire connector (wires should be green/white or green/yellow). Set the meter to 2k ohms, and put one lead on each terminal (it doesn't matter which color lead goes where). The reading should be between 500-1500 ohms. Any more or less and the pick-up coil is bad. Be sure to wiggle the wires while testing, as the wires could be broken internally which could cause an intermittent problem. The resistance reading should remain steady while wiggling, as long as you hold the test leads tightly to the terminals. If it jumps all over while you wiggle the wires, the pick-up coil needs to be replaced, as this indicates the wires are broken internally.
