Fuel pumps not running, went through troubleshooting,understand how relay board works, pin37 etc.Followed wiring back to main board, where i found the metal strip printed on the board that runs from pin 37 to the leg on Q3 then to D7 had come off the board and curled up.This suggests to me that it has been hot!
Now the question is. What is likely to be the cause.I did have some wiring issues in cable from MS to power board. Now rectified.Orientation of Q3 and D7 double checked and correct.
What will i need to replace. Other than the strip.

Any suggestions would be well received. Regards Wayne.

It would help if you posted what main board this is.

Sorry Matt. Its a V2.2. I have had the engine running but only with a bridge wire in the FP relay.

Q3 is probably damaged along with the burned spot on the PCB.

Thganks Matt i will put a new Q3 on and replace the trace and see how it goes

Problem solved, replaced Q3 and Q5 replaced the trace with thin wire on the back of the board. Also found the small crystal on the clock circuit damaged from manhandling, replaced that and it is all go.
