I bypassed the rpm relay and the pump was buzzing so all good there. Reinstalled the relay. I then bypassed the inertia switch and low and behold the car fires up like nothing had happened. Went for a drive, everything was fine. Got back on the drive, switched off, waited 20secs, tried starting the car and got the same result. Was cranking but wouldnt fire up. Bypassed the inertia and it fired up. Im pretty confident its the switch. I was meant to see if i could start the car without bypassing tonight but finished work late so will have to wait till tomorrow now.
