i have b20n vtec in a 91 civic. car ran strong every single day.i added msd 2 step the full kit with the external coil and all, car still was fine. the next day it wont even turn on and still wont. battery is fully charged, car does not even attempt to turn over just clicks.i put a new starter and it does the same thing. i have never had this problem i would appriciate any help. Oh yea if you pop start it it starts and stays on until i turn it off. when it is running it is fine if i turn it off i cannot turn it back on.

 

First, check all grounds and positive cable, from one end to the other. Have someone turn the key to start it and someone check for voltage at the starter solenoid. If none at the solenoid, check fuses and key switch.

 

what box are you running?SCI, 6AL,ect..?
