My T died on me today and now won't start. I gone through some checks after reading the no start procedures and so far I'm leaning towards ignition. Haven't ruled out a crank/cam sensor yet though.
First thing I tried was resetting the ECM, then trying a different chip. Checked the fuses and all were good. I also unplugged the MAF but that didn't help. I noticed there was fuel pressure present and after sitting awhile and letting it go down, it goes back up to normal when I try to start it. Listening to it crank, it sounds normal so I'm thinking its not anything serious like timing chain jumped and such.
I hooked Turbolink up and all the data seems normal. No codes and temps are reading normal, TPS reads normal, no clear flood. I did notice that there is no rpm when I try to start the car though. I then checked spark and I'm getting no spark from all the wires.
I need to get a noid light but I did verify 12V+ on an injector plug. I was using a crappy little multimeter that was too slow to respond to pulsing so I want to verify that the injectors are pulsing with a noid light. Since I am getting a voltage, I don't know if that rules out crank or cam sensor or if I need to verify its pulsing. I assume if the injector harness was bad or something was loose that wouldn't explain why I'm not getting spark.
So I figure its ignition module/coil pack, but I'm not sure what the no rpm on startup means or if I definitely need to verify that the injectors are pulsing even though I know they are getting 12V+. Hopefully I'll find a noid light tomorrow and verify that the injectors are indeed pulsing and not stuck at 12V+. If the injectors are pulsing my understanding is that the ECM is receiving good cam/crank sensor data and that would rule them out and leave the ignition as the culprit.
So, does my reasoning seem right? Anything else I should check?
(Edit: maybe this should have been in tech area.....oops)
