Sent ms back to brain and he discovered the ignition inputs crossed.
Still cranks low at 150rpm while jumped to a good running truck battery.
Brainy suggests going back to stock ECU, and testing for fuel and spark, so that's what I will do over the next couple weekends.
BUT, I did cut the wires to the post cat O2 sensor and removed it. Must I wire it back in when testing?
Need some help with procedures to test for fuel and spark. When testing spark, how do I disable the fuel system?
- Do I put lay a plug on the valve cover?
- Use an inline light (have one)?
- Use a timing light? (have also)
Testing fuel: what can I do other than hearing the fuel pump turn on?
(WB was showing fuel while cranking. If I put post-cat O2 back in I lose WB)
Assuming I do not have spark at the plugs, do I just start working backwards and check the coilpack? What do I check after that if coilpack is ok?
Found this diagram in a thread:
Will also edit to add last cranking log and msq.
