I'm in need of an ecu maybe. Well what happened was, i was hooking up an amp to my car and when i went to go start the car, there was no fuel coming to the front and the fuel pump wasnt pumping. I checked every single fuse, and relay. Cranks but doesnt start. I looked at where the old owner tapped the remote line and its tapped into the fan relay. I checked it using a test probe, and putting + power to the line. Last resort is to swap ecu's and reprogram. I'm thinking this because everything powers up. I even check all the grounds and everything and its all good. I use my probe to test my fuel pump and the pump, pumps. So i know for sure its not the fuel pump. So ill be towing my car to a master mechanic tomorrow. Just wanted to see if anyone had a similar problem.

 

You may have blew the immobilizer unit. A new ECU isn't going to fix that.
You may have shorted it out. Always disconnect the battery 1st.

 

yea. how much do you think the immobilizer unit cost? btw how would i check to see if i messed up the immobilizer?
