I have a 1988 crystler landau. I have replaced the auto shutdown relay, dist, rotor, and coil! I was expierecning the vehicle stalling and not fireing for a few hrs. So I done a spark test and here is what I done, I unplugged the coil wire from the dist and arked it to metal. After the vehicle stalls I do the test and no spark. Im wondering if my ecu is going out? Does anyone have a clue?

Which engine do you have? Engine Computer is the least likely suspect.

I think you mean the 3.0L V-6, I hope. The 3.3L didn't come out until '89 and doesn't have a distributor. The 3.0L does have a distributor, but so does the 2.5L four cylinder. Both were available in your car in '88, that's why I asked. Their systems are quite different in the distributor, but the automatic shutdown (ASD) relay works the same.

I just solved the same problem on my '88 Grand Caravan with the 3.0L engine. I fought that intermittent problem for 11 months before it finally died permanently. I had the advantage of owning a Chrysler scanner and I was driving with it connected. After it would stall, by the time I got under the hood it had spark again, then would start up again. When it stalled, the scanner still showed that everything that the Engine Computer monitored was working.

Since you can catch it acting up, grab a test light or an inexpensive digital voltmeter and check for voltage on the small positive wire on the ignition coil, or on either small terminal on the back of the alternator. You should see 12 volts there for just one second after a helper turns on the ignition switch. What's important is that voltage must come back during engine cranking. If it does, that means the Engine Computer is turning on the ASD relay, and that means the distributor pickup coil is working. That just leaves the ignition coil which is what was wrong with my Caravan.

Sorry it is a 3.0 6 cyl.I have not done a test like that yet but I can say I have replaced my Coil cap and rotor and asd relay. It drove for a week and the car stalled like it did in the beginning. From the get go it was the coil. Heres where I found out it was the coil. I first replaced the asd, then the fuel filter, then the cap and rotor, the last part was my coil. After inspecting my coil it was the original one from whev the vehicle was purchased, it ran fine and had no problems for the week. Then I on off 3 times and gives me a code of 42 I think whitch is the asd and a 46. So im going to replace the asd again and see if it is the problem. But ill deffinately do a volt test on it as well. Thank you for the help again. Gil.
