no pcm power

I think you need a new connector, that's going to be fun rewiring it...

sounds like it , that connecter has ever even been messed with until now, wonder how it just crapped out like that

could this also eb cause by one of the relays under the hood? i know when i was there wiggling the connector around i heard of them of clicking rapidly every time i moved the connector

It doesn't hurt to swap the pcm relay with the horn relay.

ill do that , considering my horn has never worked , may be cause of the bad relay but will do some sapping,

no go , nothing changed switching the relays around , what does re flashing the pcm do?

 

[Bugman]

All re-flashing a PCM does is to put another set of programs or program onto it, it will do nothing if the PCM is DOA.

Alright , looks like i may need a new pcm

If you leave it barely plugged in, like when you say every thing is working, will it start? If so, your PCM is fine. If you swapped the horn relay and the PCM relay, and you know the horn was not working, you may have two bad relays. There is also a blower motor relay and an IDM relay.

my batteries have slowly been going dead with me turning the key on and off , as as we speak they are charging up and i have found that sweet spot in the connector where it will turn everything on so i am leaving it alone and am gonna try and start it, i will most likely end up getting a few of those relays like you said just to be sure , the horn use to work years ago but then stopped so we never really fixed it because it has train horns on it

got it running just now , started up then died a few times , fired right back up then started lopeing then cleared out , while running if u touch the connector the truck instantly dies

Sure sounds like a connector....

Picked up the only connector I could find out if a truck , wires it all up but am left with 3 wires with no where to go

 

[Patrick Feeley]

Extra wires on the connector side or on the harness side? I'm assuming you wired it pin for pin? Cheers!

wired it pin for pin like the other, the connector i got does not have the two locations for these wires like the other connector did

What year truck/van did you get the connector out of and what year truck did you start with? And what color wires/pins are left over?

will double check on the color wires , im almost certain the motor that came out of the van was a CA van, i know for a fact it is a 97, now the connector is from a 97 truck but not from CA, i found that out after i went and bought the dang thing

Which relay is the PCM relay?
