Hello, haha,
WOT is Wide Open Throttle. According to the sjmautotechnik instructions, full throttle triggers each injector test.
I was able to test the injectors successfully by unplugging the Idle Switch and jumping the correct pin to ground. The ECU is able to fire all eight injectors.
What I meant was, the previous owner replaced the ECU once already as an attempt to solve this issue.
Is there a good way to test whether the injectors are firing during cranking or not? Could this be a problem with the fuel pressure regulator? I know for a fact that fuel is getting through the rail and out the return pipe but I can't say how much pressure it is under.
What is this second fuel pump relay? It is not on the wiring diagrams I have been using.
Thanks for the reply!!!!
