Still No Start. How to rule out faulty ECU 200 1989

posted by  someone claiming to be Miike on  Fri Mar 12 13:42 CST 2004 [RELATED]

I wrote last week about a continuing no-start situation with my vehicle.

I was driving while I noticed a loss of power, then the car died. After having it towed to my house and waiting three hours, it started up twice. That was two weeks ago. It has not started since then.

OBD-I codes were 1-1-1 for ignition and fuel injection. I checked the starter, alternator, battery, fuel pump, fuel filter, spark plugs for spark, distributor and timing belt for rotation; all were normal.

There is no spray from any of the fuel injectors on cranking the engine. On removing the fuel rail, I heard a hiss, which I believe was fuel pressure (I have not tested fuel pressure).

I went to the ECU and found all signals were normal (ie voltage and resistance for AMM, rpm sensor, fuel injectors). Ground is normal.

I spent all last weekend looking in junkyards for the infamous 0 280 000 561 ECU, but couldn't find it.

Is there a way to test the ECU itself? Am I missing anything else?
