My 93 voyager will crank over but not start. It has the 3.3L motor in it. So far we have checked to see if it is getting spark. It isn't getting spark, but we checked the wiring by the battery and have no power coming out of the main wiring harness to the coil. Everything else has power to it. The only thing I notice is the check gauges light is on in the dash once all the others go out. I thought mice had chewed through some wires, but I haven't found any chewed wires. It was running about 3 months ago and now it won't start. I replaced the battery just recently since the old battery froze this winter from not being used. I am at a loss where to look next so I thought I would ask and see if someone here might have an answer for me or some place else to check to get the van running.

Try the ASD relay (Auto shut down) sounds like it may be stuck and not supplying power to the PCM

When the ASD relay goes bye-bye you get no spark/and injection pulses it powers the coil and injectors -this is the most important relay in this vehicle get it checked out and report back.

Also check fuse the no.17 20amp in the power distribution box-

This Plymouth Voyager doesn't appear to have a power distribution box under the hood but I cannot see it anywhere else.

Hello,

The relays are scattered under the hood of this vehicle. See attached diagram.

Let me know if you are able to locate what you are looking for.
