Im stumped, but may have missed something simple
my wagon stranded me at the airport,so after having it towed home have started trying to sort things out.
I have spark (plug sparks when grounded on the body)
I have fuel pressure, at least as far as the rail (both pumps and the filter are new and working, but i dont have a gauge to measure pressure at the rail)
I have a new (to me) ECU, no start on either the original 561 or the new 951
Fuel relay tests good on the bench
Car cranks but does not start.
I have tried to run the system check on the diagnostics box, but other the red light coming on when i press the button i get no response to either read codes (1 push) or run the system check (3 pushes)
I suspect the injectors are not injecting, hence the ECU swap, but dont know how to verify this.
is there a way to test an ECU for function?
