Hello
My 87 Model 240 with 2.2 Jetronic injection died on me while driving up the road.

It was as if I had turned the ignition off...no sputter or anything.

I have fuel pressure and ignition, and the timing belt is intact, so I suspect the Jetronic CPC, although I've never had one fail before.

The engine is not getting any fuel. I confirmed this by pulling a spark plug....totally dry.

I cleaned the injector ground at the manifold.
All of the fuses are good.

My question....The car at present has a 544 CPU. I have a good spare 511.
Will they interchange?

It's cold here and the car is 10 miles from home (in my cousin's driveway), so I haven't done much investigating. If the computers will interchange, it will go a long way to helping me troubleshoot the problem.
I'm trying to avoid pulling it home.
Thanks in advance for any response.
steve
