So I have a no start issue with my crx.
1. It is not the main relay, I bought a new one checked if it would start the car/fuel pump did not fix it. Also borrowed a working main relay from a friends and still did not work.

2. ended up replacing the fuel pump and that still did not do it.

3. pulled the fuel rail and turned the car on, no spray.

4. Checked the wires at the main relay for voltage and this is what i got.


So all of the wires are getting power except the black and yellow one on the top right. I have been told that it's the wire that goes to the fuel pump. Next i checked the rear cargo area going to the fuel sender and got this:


The black and yellow wire are still not getting power on that end either.

Can anyone tell me what this means?? Is that wire even supposed to get voltage? And also can someone tell me where to trace the wire going from the main relay to?

 

Can anyone help??

 

Is the fuel pump the only thing not working? Does it turn over? Any electrical issues?

If your answers are no, no, yes(or no)...check the thermostat housing ground. If that engine harness isn't grounding properly, it can keep your car from starting and the fuel pump from priming.

 

Yeah so far the only thing i know isn't working is the fuel pump. It turns over just no vroom. And the distributor is brand new.

The car just stopped running one day. I couldn't even pop start it. After diagnosing more stuff I've come to the conclusion that the problem lies between the fuel pump, fuel pump wires, and the main relay. Because what I have been told and read, is that the yellow/black wire going from the main relay goes straight to the pump. But that wire isn't getting power and I don't know what that means...
