  1. 1G 90 AWD won’t run, ground problem?

    Anybody have any ideas? I’ve gone through so much diag and have come up empty handed.
  2. 1G 90 AWD won’t run, ground problem?

    I had my alternator unplugged during this startup and completely forgot about it. (Just repinned a new alternator connector). Cable from the fuse box to better is actually brand new. I previously had a battery relocated in the trunk, but recently made a low mounting bracket to bring it back into...
  3. 1G 90 AWD won’t run, ground problem?

    I went out today and got 2 logs of each individual issue. One of it trying to start. One is it starting up and then dying down.
  4. 1G 90 AWD won’t run, ground problem?

    Here is a log of both the car cranking over like it wants to start, and finally starting up and dying after. injectors are 1250cc FIC. Fuel pressure is consistant.
  5. 1G 90 AWD won’t run, ground problem?

    Car has ECMLink and there are no codes unfortunately..This is the thought process I was thinking but needed verification. I don’t know where to turn with the car. It has some incredibly weird issues and my options are very limited to correct the issue. Money is not a problem, but getting on...
  6. 1G 90 AWD won’t run, ground problem?

    Car cranks, will eventually fire up but there is zero consistency in it firing up. When it does run, I can keep it throttled to 2500-3k rpm, and then eventually it’s just dies all together.ECU pins 101/106 to any ground point with key off have zero resistance. When the key is turned on, the...
  7. 1G 1990 No spark. Resistance on ground circuit...

    I apologize for the super late response..So problem is still intermittent, but I’m onto something. I swapped in an unmolested 90 harness after swapping out every broken chipped connector. After install problem still persisted, no injector pulse. Key on I had 12v to each pin on the injector...
  8. 1G 1990 No spark. Resistance on ground circuit...

    The car is currently not starting and injectors don’t fire with the car cranking. The ground are verified to be good.
  9. 1G 1990 No spark. Resistance on ground circuit...

    So upon having weird issues with my car (no spark on 1/4 and weird injector firing issues) I decided to backtrack and check out some basic things.The battery was relocated half a decade ago, and the engine bay was painted last winter. This brought the idea of a grounding issue. I verified all...
  10. 1G 1990 No spark. Resistance on ground circuit...

    Welp after more diag, I still have come up with no spark. Anybody have any suggestions? CAS and PTU tested good. Coil pack is brand new. Swapped the ECU, and went thru the wiring harness with a full pin out. What am I missing here
  11. 1G 1990 No spark. Resistance on ground circuit...

    Hoping this is the issue. Haven’t got to hear this new motor come to life yet
  12. 1G 1990 No spark. Resistance on ground circuit...

    I think I’m gonna go ahead and take mine apart and see what the inside looks like. I have a spare 91-94 cas I can wire up if need be.
  13. 1G 1990 No spark. Resistance on ground circuit...

    I tested my PTU according to the manual, as well as the light bulb test and it registered good according to those tests.Is it possible for the cam sensor to be bad and still give me pulse for the injectors?
  14. 1G 1990 No spark. Resistance on ground circuit...

    Yes. As far as I know it is good.When I turn it by hand all of the injectors pulse like they should. I’m pretty sure I’m getting a pulse At the two wires (yellow 1/4 and yellow/red stripe 2/3) from the ECU. I tested my PTU according to both the factory manual, and the light bulb method and it...
  15. 1G 1990 No spark. Resistance on ground circuit...

    Trying to continue my diagnosis of this no spark issue I’m having. I blew my motor last fall, and finally rebuilt it and swapped it in.This issue started out as a no spark on 1/4. Swapped out my coil for a spare and still no 1/4 spark. I checked the wiring at the pigtail of the coil and found...
