I really need help!

thats real weird that the coil AND the injectors both arent getting power... trace the circut on the injectors untill you find the spot that isnt getting voltage, thats my best suggestion and im sure youve done that already...is it throwing a code at all? too bad its not obdII or else that would be a lot easier to figure out

on foxes (not sure about SN's since you have a little bit different stuff), the PIP is responsible for injector 'timing' signals and static spark signal. i would recheck the PIP and its wiring.

good luck.

hall effects sensor as u call it..or stator..

i know you did, but if you dont have spark or injector pulse, i would double check it and the wiring to it (the latter might not have been checked).

also, how do you know the injectors are not getting power? if an SN is like a fox, there is constant 12 volts to the injectors and the puter modulates ground to make them fire. a noid light is a good way to check if they are getting power and ground.
*I post generic info like that as i would be surprised if it is different for SN's vs a fox, but if it is, the SN guys can correct the info*.

good luck bud.

No spark...look at 12V at injectors (red wire), check for 12v at coil...if good and no spark..look at TFI. My TFI went out and replacing brought her back from the dead.

whats a tfi?
one of my commercial customers is gonna lend me his breakout box so I can try to get to the bottom of this.

TFI = Thick Film Ignition. on an SN, it is on the pass fender - under the MAF, IIRC.

does the engine crank normally? i know it sounds stupid, but is the rotor turning? u did replace the pickup in the dist? if you did all that and it still is missing the spark and injector pulse its almost gotta be the tfi module- its fairly common for those to go out, but in my experience they usually restart after they cool down.

you plugged your light bulb into both wires on the fuel injector harness and its lit constantly?
