So my oil pump went out and i pulled and rebuilt my motor. i put sti injectors in and a tuned ecu in along with other stuff that wouldnt effect fuel. i have fuel up to the rail and good pressure i just cant hear the injectors clicking and the plugs are dry. I have spark so we put fuel in the cylinders and it hits. i appreciate all the help.

this crap happened to me on the ride home yesterday!pop the hood and wiggle the wires going into the plug to the injector, very easily.see if it cuts on/off or anything changes.mine was acting as if it would jump out of the bay, i touched the wires and poof back to normal

EDIT: damn i just saw that its all your injectors not one or two....but still check the wiring for loose or shorts etc.

Check your ecu maybe its fried or the tune maybe messed up. Try finding a stock ecu and see if it's firing.
