ECU not telling Fuel pump to cut on
I installed your unit when installing a turbo kit on my car. It worked find, and the car fired up with no issues. Now that I have swapped motors and stuck with a NA setup the fuel pump is not cutting on.
I have trouble shooted the following:
(The pump was orginally didnt get the 12V it needed to start up)
I bypassed the relays and got the car and fuel pump to fire up. However after some extensive tests of the relays, they are working as they should (I pulled the cover off and manuallly tested them).
The continuity of the wire going from the relay to the ECU was check and checked out
Everything is getting voltage as it should
So I am left to conclude that the ECU is not telling the fuelpump to cut on or off.
I am still running my Calum ECU, and to make sure there is nothing ECU I am going to run my stock one tommrrow to see if it comes on.
Is there something I need to check again. I have been using the FAQ threads and factory service manual. I couldnt find anything to specifically trouble shoot the ECU
