Thanks in advance for your time taken to read this thread! So to start off, I was wondering, if I blow a relay (not sure if I have or not) will my ipdm fail? I have no throttle response, and was thinking it could be a relay, so I switched the throttle relay out, and also the ecu relay, but no luck. Could this be my ipdm, and what could be other symptoms if any? Any help would be greatly appreciated.
Thanks in advance!

 

You state that you don't know if you blew a relay, which is just about the easiest thing you can check under the hood of your car. You're replacing relays just to see if it does something?? That makes absolutely no sense. Following the path you're taking, this is going to get real expensive for you real quick.

Check the relays. If you've got a bad relay, trace the line and look for shorts or bad grounds (all the way from the power source to the terminus.)
