Ok well the vehicle isn't mine but is at my house, so I'll give what info I can.

05 Caravan 3.3l auto.
Starter does not turn over (does fine when jumped though, and already checked the wiring for good measure).
Fuel pump doesn't prime - no power to pump no switching of the relay, but pump is good.
All gauges work fine and the battery is fully charged.

When you go to start the vehicle there is no click, no drag, no anything.

My questions: Is there a way to check the TRS switch? What are the resistances to look for?

Anyone happen to have a wiring diagram to boot?

Aside from the pcm and TRS is there anything else in the circuit that would cause a no crank/fire/fuel condition? (not sure about no fire, but I'd bet on it at this point)

 

Welcome to DF
Could be the FCM/BCM, or the ASD relay is not switching power and ground. But may need to take it to a shop to have it looked at.

 

Thanks for the reply,

The owners have taken it to a few shops apparently (nobody reliable). I used to be a mechanic but without a good scan tool checking the pcm/bcm is out (man I miss having access to all the cool tools!), I was hoping to get lucky with the TRS (hoping the shops that had it before missed the TRS but ruled out the comp modules).
