BUMP ANYONE PLEASE?

 

check the grounds on the thermostat housing.

 

all your fuses good?

 

yes there good

 

take the cover off your ecu and look for any parts that look burnt. Usually when ecu's go bad it's because a resistor fried up. It dosen't happen too often, though.

 

i have put in 2 good ECUs so that can be the prob

 

did you hook up the terminals up wrong? my friend did that on his and he fried everything in the car well we replaced all fuses relays and ground and power wires but after that the radio would come on with the light switch and the lightsd came on with the ignition turned on CHECK EVERY THING!

He's right. If you accidentaly hooked up the battery charger wrong you would completely fry your electrical system. Ground wires would melt, your ecu could fry...

 

check the fuse in the fuse box for ecu and check the one that says back up.
