A little history on the car. i have a s13 sr20 with a AEM EMS V2 installed with MAP and IAT. Before this problem the car would prime normally and the car would start normally. Im tuning this friday so i double check all hoses and found out that my IACV was leaking so i ordered in a new one and replaced it. After the replacement thats when the problem started. Now my car wont start and the fuel pump keeps priming. I replaced the EGI relay and it worked at first, but then when i try to crank the car it just clicks and starter does not engage. After this my fuel pump would just keep priming again. I've read that most likely it's a bad ecu. I dont have my old ecu so i cant confirm that. Could someone help me please so i can get it tune this friday??!! I'm at a lost as to what could cause this. I have my 2 grounds on my intake manifold off the harness, ground from intake manifold to chassis and ground behind the head all bolted down. Also, every time my fuel pump primes, my battery gets weaker and on the 4th prime my battery would be out of juice. Checked the battery with a meter and it's giving me 11.89 volts. thanks for any inputs!!
