Looking for help.
I have been dealing with a no crank no CEL issue, as asked in my other posts.
This weekend i decided to investigate further and removed the signal wire (Brown Red - RN) off the starter in order to check if i had 12 volts at key position II.
With a helper at the wheel in order to turn the ignition key on, he then stated that i had a CEL.
It now seems that there is continuous 12v to signal wire regardless of key position, in fact with no key in it is registering 12v.
the other thing i noticed when testing for the 12v was that with the signal wire off and the key on, i could hear the fuel pump excite.
SO it dawned on me to remove relay 19 out of the fuse box to check if it interrupted power which it did, when i put the relay back in and turned the key, i could hear the fuel pump again so tried to start. at this point i have crank no start.
to summarize, i can repeat this cycle of crank no start and have the fuel pump excite. i checked for spark and fuel.
fuel i have but there is no spark.
In short it appears that something is interrupting the start cycle.
I now throw it you guys for the answer.
IS it the ignition switch?
IS it the Immobilizer on the Ig Switch?
IS it the BECM and ECM coding issue?
What would keep 12v at the signal wire?
