ok so im working on a friends car and we have spark i pulled all 4 spark plugs out and laid them on the valve cover and had spark..

we drained the tank got new gas in it new fuel filter and swaped out 3 sets of injectors! we have fuel pressure everywhere but the damn injectors wont spray! main relay is working and clicking on and pump is coming on! any ideas?

 

they not wired properly or resistor box is going out?

 

no resistor box and stock injectors. car was running and then this happens

 

maybe its the ecu
swap ecus to see

 

nope not the ecu
