Car Forum / Ford / Ford Falcon / October 2003EA ECU
I have been working on the dashboard area of the 1989 4 speed auto EA falcon, and after putting it back together, it won;t start. I have checked all the connectors under the dash again, and think that they are all back in correctly. Checked all the fuses and all are ok, checked the power at the injectors and get the 12volt pulse when cranking. Checked the fuel pump and get the fuel pumping for one second before the cutout operates. Checked the fault codes and get a 11, so either I have cleared them or there were none. Battery voltage is ok. However, the cranking sounds odd, like there could be a timing problem. Hard to explain, but that is the kind of sound it is. I will be going over all the sensors and detectors in the next week or so, but was wondering if there was somewhere I should look first. Yes, I know the EA should be in the crusher, but that aside, what next? PeterG I took the ECU out of the car and stored it for about two months. Is being removed from the power source important?

Possibly the ecu is fried, try one from a known good same model car. > I took the ECU out of the car and stored it for about two months. Is being > removed from the power source important?

Is there any one thing that would indicate a fried ECU, or is the only way to put in a another one see what happens? PeteG > I took the ECU out of the car and stored it for about two months.

He used to be an NRMA serviceman and has volunteered it to the cause, so I will let you know how it goes this weekend. Thank you all for your advice...
