injectors not spittin gas

[madafye]

ive changed the cas ,changed the fpr got plenty of pressure try starting cranks just wont start check the plugs after trying to start and there dry as could be. could the throttle position sensor possibly b the problem?

Doubt it. Have you checked for power at the injectors? That is where I would start.

[madafye]

ya i got power at the injectors

If you have the CAS out and spin it by hand, you be able to get something from the spark plugs. If you don't that will tell you there is something wrong wtih the CAS or the wiring. If you don't get anything at all, then you either have bad wiring, a bad cas, or a bad ecu.

ive really been wanting to think its the ecu but didnt want to i know the wiring is good and i have a brand new cas welll i guess thats the next investment if not that than the car will be brand new by the time im done replaceing everything

Are your lines for the fuel rail hooked up right? Lot of people mix them up :/

[S13_love]

Are they clogged?

sorry, thats just about all i can contribute.

[madafye]

thats what i was thinking b4 but all 4 wouldnt clog at the same time

[madafye]

ya the lines are right the 1 that pushes out the gas frome the fuel pump is hooked the fpr

Man you are not correct at all. The line that the fuel is flowing from should be connected to your filter, and then to the section of the rail that is in the middle of your intake. The return line is always hooked up to the FPR, as it is a restrictor that maintains pressure in the rail

[madafye]

ok lines are hooked up right gas is running through the rail injectors still are not spittin ne thing plugs are still bone dry

if you are getting power and ground at the injectors then take a volt meter and check the resistance at the injector you shouldnt have more than 18oms at any injector and make sure the pump gas is going str8 to the rail no fpr is in the path and the return line shoud have the fpr on it if that dosent work check the pump and make sure you dont have the terminals crossed meaning in stead of pumping it will push fuel out that should work now

[madafye]

ya thats all straight im thinking its the ecu ....just for kicks i tried reseting it and when i did the led never even came on or blinked n yes i had the key in the on position

[cd_three]

well you can open the ecu and look at the chips in side to see if they look burnt but to be honest the ecu controls the ground side the the ecu hey heres one of my head but just check it u kno that little blue relay close to the ecu yea that one change or swap it out and try that and you could lift the fuel rail with the key on and disconnect the injectors and put power and ground to them with some regular wire to see if they spray fuel if not then your not getting gas

[madafye]

i already know im not getting gas im really starting to think that its aground somewhere

whoa whoa! Sorry to thread Jack here but I am having the same problem....and I saw you mentioned something about the blue relays. There are two off the harness correct? Well can you tell me what this other blue relay (looks identical to ones off harness) needs...please tell me it does need a relay. If you believe that might be why mine isn't inform me please or call me 6018329545 thank you!

are u sure u lined the marks on the cas up the right way best way to do it is to remove valve cover have all timeing marks aligned and tdc and reinstall cas we have had the same problem b4 and it was that the cas installed wrong. if its not done right it wont give no fuel what impedence injector u runnin hi or low ?

[Jadesr20det]

We figured it out (ecu fried)..... thanks to all who posted up to help my boy out.....

That sucks, but I'm glad that you got it sorted out.
