93 Caravan: crank/ no start
So for the past 3 year I've been battling gremlins in my 93 Caravan SE.
To start, the problem started after I replaced the PCM and wire harnass. I notice that the blower motor stopped working and then I have an intermitting starting issue.
So I replaced place the ignition switch, fuel filter and fuel pump relay.
What weird is when I use my test light and test the ignition coil and injectors, it gets 12v for like 2 seconds during start and then stop.
So I'm thinking there is either a problem with the PCM getting power or the PCM is toast again.
Does anybody know if the PCM has a relay?
Can anyone help?
thanks

the problem is intermitting, the van starts probably once a day which is weird and it runs fine when it's running, but the minute I turn it off and go to start it, cranks but no start.
I tested the power going to the fuel pump, injectors,and ignition coil and the power goes on for the first second during crank and then stops.
since the PCM supplies power to these, I figured thats where my problem is. So I wanted to know if there is a way to just test the pcm but before ripping out the wire harass and testing continuity to each connector...

to give a little history on the van,
it wasn't starting, so I bought a harnass and used computer from a local junkyard. The van ran good for two weeks, then back to square one but this time it's intermitting.
