Heres the deal,I just installed an HKS turbo FMIC Larger injectors Reprogramed computer new spark plugs and a gtr resistor pack. However i started the car and it was running like ****. it would only run about 500 rpm.

I took some **** apart and found that cylinder 4 and 6 were the only ones that we firing. I checked spark, they all work.

I pulled out all of the injectors and hooked a 9 volt up to them and they all click.

I had fuel pressure cause it sprayed out when i took the injectors out.

Any suggesions on what to do next?

I want to hook my stock computer up and see if it will work

What fuel pump do you have and whats your fuel pressure?Spark plug gap?Loose ground wire?

Fuel pump is walbro 255

All of the plugs were pree gapped ngk's what gap should i put them at?

Havent checked the acual fuel pressure though.

All of the plugs were sparking

gap em at .8mm if they are copper plugs.

check your injectors! make sure you wired them correctly!

Injectors i triple checked.

The plugs i have are not copper but i will regap them anyway.

Cannoball-r reprogrammed it. I have 2 stock computers i am going to hook one up and see if that one will fire all the injectors.

Sounds like a bad coil pack. This happen to me, but it was a loose connection that kept my rpms up to 3000 rpm. If you have a bad coil pack, it might not even idle because it's not firing all your plugs.

I checked the coil packs all of them were fireing the plugs, This would lead me to belive they are all fine

Sorry, I meant the resistor pack (Grayish thing) on the back of the center cover that is 4"X4" in size and plugs in from the top and bottom.

i think you're referring to the transistor ignition unit. thats the 4x4 square that looks like a heat sink.

the resistor pack is something else (fuel injector related, not spark. it looks like a mini silver stick of butter)

I got the resistor pack brand new from nissan. I hope this wouldn't have gone bad.

I was talking about the transistor ignition unit thing. Not the resistor pack.

are you sure you wired the resistor pack for the injectors correctly? test the car with the the stock ecu and report back--let me know.

This is what i did last night:

I installed the 440 injectors onto the fuel rail. Hopefully i hooked the lines in correctly.

But I disconnected my injectors and connected them to the stck injectors that i held in my hand. I turned it over and could feel nothing with the aftermarket ecu.

I then plugged in my stock ecu and cracked it over, i could feel everyone fire over.

I then dicided to plug in the 440's and try to start it with the stock ecu, i still wouldnt start.

It seems that the ecu wont fire the 440 but it will fire the stock injectors. That is ****ed up!

Mind you i took out the spark plugs again and they all spark.

Ohm your injectors out they might have an open. Either that or they are shorted or stuck closed. Try Putting a noid light on each plug and see if it fires. Its a little light you stick on the injector plug and flashes on the ecu pulses. Crank it over and have someone tell you if it flashes. It it flashes then ECU and wiring are okay. Then condemn the injectors. Get an ohmmeter and ohm it out by placing the plugs on both the pins it should read. If not the injectors are open. If they read then your injectors are stuck closed. Lemme ask 1 question... you sprayed the tips of the injectors with carb cleaner to think it would clean them out didn't you? Do all of that and get back with us, Don't do the carb cleaner thing.

I didnt spray the injector with carb cleaner, Tonight i am going to istall the stock njectors so that i can hold the 440's while i am cranking the engine and either noid them or see if they are clicking.

thank you

Ok this is not getting any better.

I have the stock injectors installed and the stock computer installed.

I had all the injectors unplugged and i plugged in the 440 (held them in my hand) and turned it over. They all clicked.

I then plugged in the stock one installed on my car and turned it over.

It sounded like it wanted to start but never did.

I then put in the reprogramed ecu same thing.

Now i am clueless.

I have pressure to the rail. The injectors are being told to fire and i have spark. ( maybee the spark plugs dont work when installed) They work fine when you ground them to the engine.

Any suggensions im getting pretty pissed off considering the gays *** ****ing car was running fine before i decieded to **** with it.

I got pissed off and dumped fuel down the intake and it ran on all cylinders.

It has to be fuel related.

Here is anouther happy note

I was driving home from work last night and a tire blew out from the car in front of me and i now need a new hood and front bumper for my WRX.

LIFE SUCKS!!!!!!!!!!!!!!

my old man had the *exact* same problems on his KAwe tried evertyhing, injectors clicked, spark, fuel, and everything worked, or so we thoughtturned out to be the fuel injectors cloggingmassive huge clogstake off the rail, blow cleaner through *everything* and get your injectors cleaned. if they have been sitting a while, they will close up a lot of the time.

How did you unclog the injectors without ruing them

easy, send them to rc engineering to have them clean and flow bench them.you could also try filling the fuel rail and filling a fuel filter with seafoam or some kind of injector cleaner and that way fuel pressure forces the cleaner thru the injectors.......

Sounds good.

This weekend im going to take the rail off and zip tie the injectors on and turn the engine over.

Then i will be able to see if they are infact firing.

Here is the latest news.

I unrapped all my wiring and checked it, it is all fine.

I installed my stock ecu and injectors. I took the rail off and watched for the injectors to fire. They all worked.

I then put the 440 injectors on and none of them worked.

I installed my reprogramed ecu and used the 440 and it didnt work again.

That is the wierd thing.

All of them are stuck. I could belive 2 or 3 of them,

And also why would my stock injectors work they have the resistor pack hooked up to them.

All right here is the deal, i got the car running using the stock ecu and injectors. I still have the resistor pack hooked up.Cannonball-r told me that it shouldn't run with the resistor pack on but i couldn't figure out why.

All the ohm readings are correct, showing that the resistor is hooked up right.
