f1race79 Posted April 16, 2010 Share Posted April 16, 2010 I picked up an 83 280ZX NA at a car shop, the PO charged backwards. They have lots of things pulled out and laying around. Shop put in a new ECU, I think they zapped it. I got it home no fuel pump or start, swapped ECU and pump is running with about 40 psi of fuel. Injectors not working will start and run on starting fluid. I have run test in manual. Everything seems to be OK but injectors still won’t work. The question I have is the negative side of the coil seems to send signal to ECU to ground and fire. Where does the ECU ground to? Which ground? Any info on this would be helpful.
