Does anyone know what might be the problem? There are 2 fuses for the ECU... for some reason my car died last night and all the mechanic did was replace my 15 AMP ECU fuse and it cranked right up... but now it wont start again, and everytime I crank it with a new fuse in, it keeps blowing... can anyone help? my car wont start and I have no idea how to fix this.

15A? The one under steering wheel is 7.5A and one under hood is 10A. Maybe that's your problem... or maybe I'm wrong.

no its 15a, it says so right on the fuse cover under the steering wheel

Oh, strange. Must be the year differences.

There is a 15amp fuse for the SRS, Trans, PGM-FI, Radiator Fan Control Module, VSS and charging system. It's # 23 under the dash on the SRS fuse block.

15a is also for the ECU, so i guess no one has ever heard of this happening...someone told me to check the wires at the ECU to make sure nothing is touching metal or anything ...

Fuse #19 (ecu fuse) is 15a and it blows when I just turn the key to get power, the other fuse that blows is right above #19 right next to the SRS fuse which is a 10a. On the diagram on the back of the fuse box cover it is listed as an ECU fuse (15a). Those are the two fuses that blow right away even before I even get a chance to start the car. Does anyone know what could be the source... I have my ECU out and have been looking at it, but I'm not quite sure what I'm looking for. please help. Thanks.
