PCM needed

Here is a link to your previous post about this issue:

No Crank No Start Dodge Van

1997 dodge grand caravan LE 3.8L The van started okay, let it warm up for a couple of minutes. Then put it in reverse backed up a few feet then it died. When I went to restart it I had a no crank no start problem. Checked the battery it was okay, but tried a jump start anyway but nothing. Checked the fuses and relays even swapped out the relay just in case still nothing. Checked that the starter is getting power and it is gave it a few taps and still nothing. If you put a jumper wire across pins…

In that previous thread you stated that pin 8 of C1, going to the PCM for the START RELAY, went to near zero volts in the START mode. That is exactly what should happen in order to activate the relay, make a connection to ground. If that information is correct and the wire connection going to pin 85 of the relay is making solid connection then the relay should work.
