Greetings,
My car decided to die while driving the day, seemed like it ran out of gas, would not restart. I've been reading here the past couple days, have run a few tests and believe my ECU has decided it's time for a rest. Here are some details:

1991 240 wagon
LH 3.1
Car starts/runs when fuse #4 is jumped to #6.
12V present at Fuel Pump Relay, red and orange wires
Car starts/runs when the blue/green wire at Fuel Pump Relay is jumped to ground.


The car has ECU, Bosch # 0 280 000 572

Person at local scrap yard tells me I should run a 0 280 000 951

He claims the only dif. LH 2.4 to LH 3.1, is the AMM and the TS and that the computers are totally interchangeable.

I'm hoping Art and other FI experts will have some knowledge here and know weather I can run the easier to find ECU.

Thanks,
Scott
