well are the injectors not firing or the the fuel pump not turning on? make sure also that the injectors are getting 12v on crank and run.

the fuel pump does come on and i took the injectors and tested if they open and close.. and they do....

could fuel pressure be the case?

i think it might be because the gauge on my FPR is under 10.. and ive tried adjusting it but the fuel pressure will not go up... is my FPR bad... and could that be causing the gas problem?

Either your fuel pump or reg are wrecked or both. That will be the start.

Also have you done an injector test?

You need to look for a function called CONFIG_CYL=04

Once you find this. Press the mode button and bring it down to 0.

This will fire all the injectors and switch the pump off, put your hand on each injector(or disconnect it while the test is active) and make sure they are all pulsing). This rules out injector driver or wiring.

Also i sent you a pm.

yea the injectors are good... they are pulsing... but one injector was leaking from where it went into the fuel rail... and when i took it out the O-ring was broken. Could that make me lose Fuel Pressure? i mean it was leakin bad.. i could hear it when the pump primed.....
So i ordered the O-ring kit and i hope that helps..

and the fuel pump should be good because its brand new... but how can i test and see if its broken?

Can you hear it?
If its on and still no fuel pressure means you got a dud. A small fuel leak wont make you loose allyour fuel pressure or most of it. Only some of it.
