What to look for on 91 240SX ECU injector problem

[alexh]

I have a problem with the car running very rich intermittently -

I have run through all the checks in shop manual and many others.

I'm down to -

Injectors- can an injector get stuck open on it's own?

FPR - haven't checked this.

ECU - Initially I didn't believe that water in the ECU would affect every car the same but a few people have reported on this problem.

After taking the cover off the ECU, what should I look for?

If I'm not able to correct this problem soon I'll have to junk the car so I would appreciate any help.

Sounds like your car got flooded. If so, disconnect every harness connector and use a hair drier to dry out the pins; if the ECU has water in it, do the same thing.
