Dont toss a plugged CAT as the culprit, my fathers Avalanche had a similar code list that was the result of a clogged cat. His truck did start, but anything more than a pink toe on the throttle and it would misfire and start to die.

 

Even if the cat was clogged I would still get spark. I've checked the grounds and cleaned them up, not much but a little corrosion. Still no spark.

 

Good point on the battery Oldblue
. Well worthy of checking.

 

 

Look at the harness, especially where the wire bends around the EVAP purge valve bracket.
The EVAP purge valve is probably stuck open, or the tube is cracked, causing a few of those codes. The purge vale is NO.

 

I found the ground wire that goes to the ignition coil module isn't providing ground I ran another ground wire to the connector and hooked it up, checked it with a test light and now have ground. All my check engine lights have gone off but now I'm having 1 code b1325-03. FYI I am now getting spark and fuel but still not firing

 

That means you probably blew a fuse. SDM, radio, Instrument panel or BCM. Or just a battery below 9 volts. Or the ground is also for 1 or more of those.

One of the things the code does is inhibit setting other codes.

 

Battery is 12 volts, 530 cca, tests from new and no blown fuses.....

 

It takes "the control module detects a system voltage less than 9 volts for 5 seconds" to set the code.

Do the modules I noted work? SDM is the restraint system.

If it was a one time thing it should clear itself. You could clear it see if it comes back.

 

Don't really know. Gave up on it for the night but I cleared the code which was originally showing through my scanner as a transmission code. Cleared it, tried to start it again to see if the code came back. My auto scan ran, then the only code showing was through the parking brake system but it was the same b1325-03 code.
