so i was driving down the road and my car just turned off. i checked the fuses and the ecu fuse keeps blowing. any ideas on why this would be? do you think it could be a bad ecu? any way to test the ecu. i also have a 94 camry le both auto, could i pull the ecu out of that one and put it in the 95 to test the ecu? any help would is much needed, thanks mike

 

Exactly which fuse is blowing?

You can swap ECU's if they have the same part numbers. Part number is based on engine and trans model, emissions certification-CA or Fed, etc.

 

i belive its a 15amp fuse the ecu one.

 

There may be 2 ECU fuses:

ECU-IG powers

A/C pressure switches
ABS
Antenna motor
Seat belt buckle switch
Combination meter
Cruise control
Cooling fan ECU on V6
Tran shift solenoids
Coolant sensor for radiator fan
Trans shift lock ECU
Radio fan relays


ECU-B powers

ABS
Day time running light relay

 

well i had a machanic look at it, and he said its the fuse that gives the fuel injectors power, same with the fuel pump, ecu, dizzy, the car cranks over but it has no spark or fuel? does this help?

 

Guesing AM2 Fuse.

The fuse powers the:

Coil
Ignitor
Injectors
Fuel pump via the Circuit Openning Relay

Wire colors going from the fuse are Brown/Orange and White/Red.

You can start by disconnecting the power wire to the coil (White/Red) and determine if it is shorted.

The Circuit Openning Relay is behind the glove box in a relay panel. You can pull the relay to disconnect the fuel pump.

Check wiring to each injector to make sure it is not shorted to ground.

The ingnitor has its own wiring plug the can be removed.


Is the a V6 or 4 cylinder?

Did the mechanic check the timing belt and make sure it was not broken.
