Look for damaged wiring in the engine compartment and under the dash. Look for and smell for burned wires and also look for rodent damage to wiring, see it a lot, look for signs rodents are trying to nest. If the computer needs to be tested or rebuilt I have great luck with Fuel Injection Corporation in Livermore CA, great company to deal with in my experience. Make sure ECU is isolated from water/corrosion.
the car was running when it got to the smog shop, and when it got hook up is when the ECU fuse burn up, what do you think that could of cause the ECU to go bad?
