Ill start by saying i have a 92 civic with a d16z6 swap. The car run for about two months after the swap and the starter went out. Replaced it and now im noticing that the fuel pump isn't priming. I have replaced the pump and the main relay. It has p28 ecu and the cel stays on. Im stumped.

 

Is the G101 ground wire on the thermostat housing disconnected?

 

I dot see a ground wire on there or where it would bolt up.
Does it just bolt from the thermostat housing to the manifold?

 

 

Would that also explain the cel light being on?

 

yep

 

Thanks, ill check and get back with the the result.

 

no it wouldnt if the ground at the thermo housing wasnt attached there wouldnt be any cel's that ground is for the ecu

wow RonJ@HT you have over 20 thou post and still provide false info

 

You sir don't know what you are talking about. Did you read the thread? A disconnected G101 ground will cause the CEL to remain on steady (not blink) both with and without the service connector jumped. This is referred to as CEL code 0. Familiarize yourself with the CEL sticky at the top.

 

Okay so I checked the g101 it looks good, I tried pulling the cel codes and it wasn't giving me any. While checking for them the fuel pump came on the cel went off and it stayed at a steady idle for a min or so and then shut off. The cel came back on and now im back were I started.

 

Unplug ECU connector A and then turn the key to ON(II). If you ground the A7 or A8 terminal (Grn/Yel wire), does the fuel pump run? Try this test multiple times to see whether the pump always runs.

Okay I found the grn/yelw wire on a7 on the harness, so to ground it I need to do what exactly?

 

Ecu was the problem. car is now running good. thanks for all the help.
