Hi,

I have a 97 plymouth voyager with the 3.0L engine and 3 speed transmission.

A few days ago I decided to wash out the engine area at the car wash (I've done this dozens of times before). About 15 minutes later, I made it home and left the car running in the driveway as I was going to leave somewhere again. Well, it stalled. I tried to turn it on and it wouldn't turn on.

I did do some checks as I am a pretty good hobby mechanic and found it had no spark.

I thought I would change the crankshaft position sensor first, which did fix the problem. However, about 20 minutes later it stalled again.

I changed the CPS 4 times now and it won't run for more than 5-20 minutes before I need to replace the CPS again.

I did try changing the computer & then the CPS but the same thing happened.

I tried to wait a few days and then try again but that didn't help either. I did change the CPS as part of a tune up I did a year ago.

What would cause the CPS to short out so much? It's been atleast a week now that that I washed out the engine and would think all the water would have dried up.

Could there be a different problem, and changing the CPS is just partially helping it?

Any advice would be great!

Check in the fuse and relay box
looking for an ASD relay
mark it and switch around with a similar one
give it a try
also check and suspect the coil if the relay check out OK

Hi,

I replaced the ASD relay & CPS today. The van ran for about 4-5 minutes and died again. I am not getting a spark just as before.

Any other ideas?

Thanks
