HELP! Car died, fuel related!

[USAFguy22]

Yeah, and the car if getting fuel just fine. I pulled the last CEL (should have just done this to begin with....) and it's throwing code 15 at me, ignition output. I'll be running through the flow chart in the service manual to try and narrow down the problem. I didn't think to check it before since the car would just turn most of the lights on for the bulb check.

Yep still looks like the igniter module or the ecu.. I would also check the g103 ground

 

[USAFguy22]

Igniter was just replaced, where is that ground located? 1 step closer

I think its the one under the igniter rear bank

suddenly statioairy!


There is a relay behind the passenger seat. It's a dual relay: 1st supplies power to fuel pump for 5 seconds after turning on ignition. 2nd supplies power thereafter. (PGM F1 MAIN RELAY) Mine has failed 2 x due to vibration cracking the soldering where the relay mounts the pc board- inside the PGM F-1 outer box. I re-soldered mine & it works fine. Ill try to attach photo.

If it's the ground wire that connects to the throttle body I checked that one, is there a main one that grounds the engine sensors any everything else?

I replaced the main relay even though the fuel pump and ecu were still getting power.

Check page 11-56 in the manual and 23-19. Seems like it is a ground or like you said a bad ecu

 

[USAFguy22]

Success! So I decided to check the grounds and the ground for the igniter was the reason it wasn't firing.... I don't understand how it would work for 6 months and all of a sudden not. It didn't move, the threads and terminal were clean, and bolt was tight. Anyways I just extended it to a different bolt on the throttle body and it fired right up. What an Easter egg hunt...

Sweet!!! Glad you got it!!

Sometimes a seemingly expensive fix is something very simple.

Glad to see you found the issue.
