Alright, 90 Civic, B20B, running obd0 will not get fire to the injectors. Good Spark, Good Fuel Pressure, but injectors no worky! I purchased a noid light today and i am getting no voltage whatsoever at the injectors. Double checked all my MPFI wiring and it is correct. Tried a diff ECU and same thing. I know the Main Relay controls the fuel pump but would it also make the injectors pulse????? Any help would be greatly appreciated.

 

Yes it also controls injectors, try one that is known good or try that one in another car

 

i was told that if it clicks 3 times before crank up (1. when the key goes to acc and CEL comes on 2. When CEL goes off before cranking 3. Crank up. It does that and i hear the fuel pump buzzing.
