I'm having real issues with the DOHC EJ25 in my buggy. It won't run and is showing a heap of fault codes. This aftenoon it only had four fault codes, now it's showing six.

The fault codes are for; crank angle sensor, MAF meter, O2 sensor, Idle air control motor, throttle position sensor and water temperature.

A mate and I spent a few hours going over the car tonight and couldn't fine any obvious problmes. There computer appears to be fine and we had plenty of battery voltage. All the relays seem to be working and all the earths are good. We doubt the faults are the real issue. Instead, we think there is something else, simple, but causing the electrical issues.

If anyone has any ideas as to what to try next, they would be highly appreciated,

miserable and soon to be broke,

Pete

figured it out, bad ECU main power relay, led to voltage drop, led to cranky engine. :o
