ITS RUNNING!!

I check Inerta the other day it was in the down position.
I rechecked today still in down position so i pushed it up and grounded pin 6 still clicking at relay.
pushed inerta back down 6 pin to ground and fuel pressure gage at rail jumped to 40 psi and truck started right up. Reset?
Couldn't have done it without you all.
Thanks so much
I have this odd feeling i didn't have to spend any money at all. Ouch

You should start your own thread for your issue.

The constant running fuel pump and lack of getting codes point to a bad computer. Dozens of threads here with the exact symptoms as you are having.
