injector problem maybe?

sen2two · 05-20-2009, 04:02 PM

ok, so the fuel pump is brand new and i can hear it running (inline walbro 255). and i can actually hear the fuel running through the lines on the motor. also, i can see the fuel pumping back into the fuel cell. its in my trunk. so i know the fuel is getting through to everywhere... i swapped the primary injectors because i thought this was the problem. i "checked" them to see if they worked by putting a 12v source to one prong on the injector and grounding the other. i heard them click. so i figured they were good.

if my injectors are fine, and im getting fuel pumping just fine to everywere, what else could it be? ecu? air flow meter? something else?

i know the injectors are not firing because the spark plugs are brand new and i pulled them after cranking for a little, and they are still brand new. not a drop of fuel on them. also, i got it to start while spraying starting fluid...

if you apply voltage to them out of the car and you can see them actuate or hear them click but when they are installed in the car they dont? you may have a wiring fault.

Sounds like a wiring, CAS, or ecu fault to me
