I already read the posts it brought up pertaining to this problem, none help or explain my problem.
To start had an EPROM ECU blow #C201 leaking all over C4 and Resistors R255 & R256 so I bought another EPROM (Both MD312464) and installed. After driving for a bit started getting rapid clicking coming from the MPI relay that runs the fuel pump, injectors and ECU. I bought brand new relays thinking it was that and installed and they still clicked and gave fuel cut-out while starting off in first from lights and stop signs.
Did some looking up and found it may be the fuel pump going out. Bought a Walbro 255 and installed just today and drove the car for a lil bit and it seemed alright. When I got back to the house and sat parked for a bit it idle surged for a couple hundred RPMs then the clicking started again. I read some of the posts and have not opened the other EPROM, some of them say it may be the ECU resetting the relay for the fuel pump because of a leaking CAP. I need to know if the CAP and Resistors I stated above work for anything to do with the MPI relays?
If not are there any Ideas what it may be? I've heard injectors, and I have 1200cc injectors waiting to be put in but I do not want to put them in till I have an EPROM fixed and set with ECMTuning and put my bigger turbo in and go for a Tune and Dyno.
Need some help, wanna get this beast going.
