ok i have a h22 swapped eg
i used a noid light on the injectors it flashes as it should and i have 12+ at the injectors i have tried 2 diff sets of injectors and none will spray.... I have the right fuel pressure i can't figure anything out my ? is should i have 12+ since it has a resistor box someone please help i have searched and searched or any ideas would help

 

I have also tried 2 ecus and 2 main relays timing is right it will run if i spray starter fluid in the intake

 

did you check continuity from the injector plugs to the ecu? 4 of the 8 wires from the injectors go into a 4-p connector on the passenger side, then they go into the ecu. check all those connections.

 

Yes I did I have the 4 hot wires from the resistor box going to the injectors the one wire left on resistor box I took one of the 12 volt key on wires that was left over and wired it in. So when key is on I have 12 volts @ hot side of injectors and when key is turned over the noid light flashes but injectors will not spray... I don't understand what's going on cause i can turn the car over with injector pluged up but holding it up to my ear and hear it clicking so if its clicking and I have plenty of fuel why am I not getting fuel?

 

how do you know they aren't spraying? and where are you reading fuel pressure from?

 

Because it won't start I have turned it over with the fuel rail out of the motor and me holding the injectors in the rail and it does not spray at all... and I have a new walbro 255 in it and also pulled one out of a running gsr hatch it is getting plenty of pressure

 

If they won't spray that is ether a fuel pressure/supply issue or a wiring issue.

What resistance are the injectors and how do you have them wired?

 

It's just oem h22 injectors. They are wired hot side through resistor box as I said earlier to the best I can tell it is wired right I know I have the 4 hot wires from the injectors to resistor box. I have one of the 12 volt with key on out of the dead end plug to the resistor box for my 12 volt to injectors the negative side is ran through factory harness to the right pins on the ecu for each injector.. but what I don't understand is if I can hear them click that means they are actually opening right? I plugged a extra injector in had my buddy spin it over and injector clicks just as it flashes with a noid light. So if its clicking could it still not actually be opening?

 

can you take a pic of your setup? where are you measuring fuel pressure from? do you hear the pump priming? pull the fuel rail off the fuel supply line and get your buddy to turn the key on and see if fuel sprays out. hold a bucket up to your open line. it sounds like you have a complete blockage.

 

I haven't measured fuel pressure I have just used 2 diff walbro 255s 1 out of a running car one new... I'm getting plenty of fuel if you turn the key on with the fuel rail out of head but injectors still in it will blow all of them out with the quickness you have to hold all 4 very tight before key on its not a fuel problem the pressure is there its coming through AN line and inline earls fuel filter its getting plenty of fuel... I have quite a few pics on my MySpace but prob none that would help you see how its set up...

 

What ECU are you running? What year injectors? Do/did they work before you installed the resistor box?

 

I've got the stock h22 ecu and also a chipped p06 I believe may be wrong and I know both are good... the injectors came out of a running 93 h22 swapped hatch so its not the injectors I'm at a absolute loss I carried it to a shop and they can't figure it out either... thanks for trying to help tho

 

And I never tried it without resistor box don't wanna kill my ecu will it hurt it if I just try it for asecond without the resistor box to see if it will run? Like literally no more than 20 seconds the drivers shouldnt get to hot that fast

 

no it won't hurt, try it.

 

Test the impendance on your injectors, verify they are indeed stock H22s. Then verify you have all your wiring installed correctly. Black/Yellow in and out. Other wires direct to the ECU as expected. Then double check your continuity on your wiring....as I have had a bad wire previously in life.
