I have been a lurker in the shadows absorbing all information I can but don’t have much to help anyone. My problem with my 2003 LT with 157,000 miles on it is it cranks but won’t start.
At first we decided that the fuel pump went. The relay was good but pump wasn’t charging. So I changed that out yesterday. No codes were present on my reader. But it didn’t fix the problem of course!
Checked the relay again that’s still good so started to check the panel. The relay gets juice but the panel isn’t sending it out to the pump. Jumped the panel and the pump charges but still won’t start. Checked codes again with another reader and these came up in this order:
C0235- rear wheel speed signal circuit open
U1000- no state of heath from module
P1682- ignition 1 switch circuit 2
Any suggestions? Should I replace the ignition switch or start chasing grounds first??
