SR20DET fuel issue's....Please help....I dont ask much.....
Ok ..... I was having major problems getting my car started after the swap (blacktop S13 into an S14) I have found out now that my injectors (50# MSD's) are not working, they leak a little but do not spray fuel, they also have no signal while testing the plug with the test light....??????
I can get the car to sputter with carb cleaner, and I know its not the timming, I pulled my fuel rail and injectors out and even tried to start the car with the injectors out to see if they sprayed, they did not....This is the only thing holding me back from meeting my goal on the 14th of this month (sat)......
I really need help......

It is wired fine, they were getting continuity about 2 months ago and now they arent.....
Thanks for the obvious dipshit, But i dont think I'll be getting rid of brand new never used MSD injectors.....
Anyone else got an idea of what the problem is? I've never had a problem with this on any of my SR's or the ppl ive done swaps for......
I'm thinking it something stoopid and simple but im just too burnt out on it to figure it out.....this has been the longest swap I have ever done..........

WTF?! he has pressure...just no NOID
what are you lacking? are you having 12v on one side of the inj? or are you having the ground pulse? check with a voltmeter to see if you have 12v key on ign voltage on one of the inj. wires. if you dont, you need to see why you dont have it, i dont recall exactly how they are wired (wiring schematics are your friend!) but if you have a schematic, i can figure it out for ya.
it isnt a honda, so i am not gonna make fun of you...i will actually help on this one

its a signal issue...not fuel pressure (more then likely...)

IIRC, the trigger signal from the ecu to each injector is only 5 volts- not too sure if you will read that with a test light- try a voltmeter. Do you have good continuity between each injector plug to the ecu? What type of ecu?
Edit:You might want to recheck the ecu harness for disconnected grounds also.

you wont get a test light to light up if you are testing injectors. Hook it up to a relay and listen for a click. power the 85 to 12volts and power 86 with the - injector lead. (the injectors fire by ecu giving a - trigger)
