ok i got a b20vtec that ive built this past winter and i have it in the car and i am having trouble with it starting and staying running. heres the run down... b20b block b16 head gsr trans cp 11.5;1 pistons eagle rods all super tech valve train skunk 2 cams intake manifold 450cc blue top injectors. neptune base tuning software. i have a resistor box on there and on the fourth cylinder the injector is having continuous power. im gonna get another one tomorrow. i have went threw and make sure i had good connections for the grounds. any suggestions what could keep it from running?

 

Not sure I understand, "on the fourth cylinder the injector is having continuous power".

The injectors are supposed to have "continuous" power as long as ign. switch is on, the injector is "fired" buy a ground pulse from the ECU/ECM.

If you mean the injector is on all the time, [flooding cylinder 4] the problem is the ECU/ECM or the injector lead from the ECU/ECM to injector 4 is "shorted" to ground 94

 

whats ground 94?

 

Ignore the 94, ground= 12V-, [neg.(-)] the ECU/ECM supplies a ground pulse to trigger the injectors. 94

94= me saying ten four. 94
