I've got a ej20g (coil pack on top style) in a porsche 914 and wired to a Stinger EMS.
It won't run. The closest I can get is holding the throttle open I can get it fire a but but not run on its own. I know I have fuel, spark and I believe my cam and crank signals are correct because it is reading a steady RPM on the ECU. Unless I am really messed up, the timing is set correctly.
This is a very simple ecu. It needs cam and crank signals to send the signal to the coil, fuel and air and not much else. I am missing something though.
Any ideas?
I'm going to do a compression and leakdown test tomorrow.
Here is the wiring diagram. I told you it is simple!
