Shut off while driving and would not start, does it have an ASD?

My husband has changed the ignition before it did not help. It totally cutoff at high speed. It seems not to be getting fire.. No I cant do a video. It just spins over. Has no crank fuse. Changed a relay that works with coil pack. Still same turns over no crank. Its a 93 so its different from newer ones.

Husband has a scanner we will check those tomorrow. Trying simple things first.

He said it wasn't getting fire coming out of coil to plug, I believe. Yes, I was thinking crankshaft sensor too, but I have to wait for husband to check it since you know how things go. I have to order it from different stores just in case. I'll pick one up tomorrow. But he is frustrated with it, so I have to let him do as he does to check it out. He is a mechanic but gets stumped sometimes. I let you know. But there were right many codes relating to transmission speed sensor and the shifting and so on. But he said those don't matter as far as engine running. But would crankshaft sensor shut down at 50 MPH wondering.

Well, nothing seems to be helping. We changed the crank sensor. Spins and no cranking /starting. Even changed the cam sensor. Has fuel pressure. So not sure what to do. Starting to be money pit. My husband is a mechanic but stumped. It's not reading the codes, no communications between scanner and van. Seems it's something to do in the wiring. All fuses are good. Need the correct wiring diagram for fuse box and relays beside it behind the steering cover and the engine coil and starting diagram if you know what I mean. The part where it comes through the coil output input. 1993 dodge grand caravan es 3.3.

Okay.

Snap-On scanner does have it on there just not communicated with scanner. Under hood has a plug and under the steering wheel has a scanner plug one is Chrysler 1 adapter and one is Chrysler 2 adapter. One is for body scanner and one is for engine scanner.. It spins over fast I haven't tried starting fluid but I'll tell him to see if it will still not sure which relay is the auto shutdown relay. So many of same thing they all look alike. There are replays behind the cover at steering wheel that are not accessible until you remove large cover.

Thanks for your help and info we had some help from another friend mechanic tonight checking it out and have come to the conclusion that the engine Computer is needing to be replaced. It is. Not putting out enough power from it to make spark and power to all things. It has some voltage but just not enough.

Our friend followed the sensor book we have with the testing instructions with test light and other things.

The computer is the best choice since relays are doing as they should. Together they ran quite a few test and this seems to be best choice. I have ordered one but it takes a while to get it to store they said by Friday a week from now unless it comes in sooner. Not really as much as I was thinking it would be.
So I can't really complain the van has been a wonderful van. It hasn't been down many times.

The main thing I love about the van is the amount of space that is on inside of it. They sure don't make them like they used to. Hopefully it will be fixed soon I'm sure missing it. Thanks all.

Well, installed it and nope it did not crank of course only few minutes was spent on it. Husband was tired from work all day. I'll let you know. At this point I'm frustrated with it.

No running at all. Spins over no crank. Not enough spark. Replaced the ECM computer still same thing no change.

Reply that was the first thing but didn't help. So, the solution last night was since we had replaced crank and cam sensors and a few other things. ECM computer included and it did not crank only spun over not start. Someone suggested we unplug the transmission control module and see if it would crank up and guess what it did start I was doing the happy dance. But then we decided to change the computer back to the old one to see if it indeed was bad too and yes it did not crank with the old ECM computer, so we put the new one back on. So, we now know for sure the emc was bad and the transmission control module on passenger side firewall was bad too. The transmission control module cut the van off at 50 mph and locked where it couldn't start again the solution was figured out. We are now ordered the part and waiting on it the ship to store to get it to put on. We never thought the transmission control module could shut down the van while driving down the road. But we do now know.

Sure it has been a roller coaster of things to which we still don't know the cause of it, but at least we will get it fixed soon when part comes in.
