i went and got a ecu from crazy rays...our local big junk yard and when i put it in the feul pump stopped working..so i put my old one back in and it worked again..im prolly going to go and get another one to make sure tho...is there a way to test it and make sure its all working good?

 

I would check the wiring if all the parts have been replaced and it still doesn't work. If any of the wires in the ignition system is broken, then it won't work.

 

i checked everything..i check all the wires leading into the ECU and i found continuity with every one...
