ICP related issue.
 

My truck when you start it lopes an throttle pedal is unresponsive.. Unplug the icp its fine.. Replaced the icp sensor... twice... new hpop, lines, ipr, cps, fresh oil. Any ideas?

It drives fine with the ICP unplugged?

yes

I would check the engine wiring harness...sounds like an electrical issue to me. Check the icp and ipr well for any rubbed, melted or broken wires.

Is your truck chipped or have a programmer? Do you have acess to a scan tool?

Yes its chipped ts 6 pos and it does it with chip out. An yes I have snap on scan tool

On the datastream with the icp plugged in what is the icp psi reading? Unplugged icp should read about 700psi...

It will not run plugged in

It will not run at all plugged in? Did you check out all of the wiring?

Do you have a cel/ses? Any codes?

Only has codes when icp is unplugged

Did you figure anything out with your icp issue? Find any rubbed, broken or shorted wires?
