Hi,

I have a 93 Accord EX that won't start. Please read all.

I have been having intermittent transmission shift problems for a
couple weeks now but they would dissappear for a day or two after I
disconnect the neg. battery cable to reset the Transmission ECU. I
suspected the problem to be the Transmission ECU after checking the
solenoids and sensors. I also tried getting the diagnostic code but my
check engine light would just stay on and not give me any codes.
Anyway...

Last week I got in the Accord and it would not start. It turned over
strong but would not fire. I thought that the Transmission ECU finally
went and that it would not allow the engine to start. Well here are my
findings...

I disconnected the battery, pulled the Trany ECU and also the Engine
ECU. I first opened up the Trany ECU, everything looked normal,
nothing burnt or discolored. Then I opened up the Engine ECU and there
it was, one of the transistors was totally fried. I was able to get
the numbers off of it (c2655) to get a replacement and the resistors
around it checked okay. I figured I'd give it a shot so I ordered a
couple of new transistors.

Today I installed the transistor, checked all the fuses and put
everything back together BUT the darn thing still won't start. Took
the ECU back out checked the transistor, checked my solder joints
again and checked a few other components. Everything that I could
check was okay on the board. Obviously something else is fried
probably a chip, I just can't see it.

Now to my questions.

Is this a frequent problem? (the transistor or ECU frying)

Could the Engine ECU have caused the intermittent transmission
problems all along?

Do you think that the transmission problem/Trany ECY could have caused
the transistor in the Engine ECU to fry? (The two ECU's share some
information/wiring)

What do you think could have caused the Engine ECU to fry?

Should I take the chance and get a new Engine ECU at the junk yard or
off the net and hope that it works?

Do you think that a new ECU will also get fried?

What do you suggest?

Thanks,
Tom
