No fuel to new rebuild
ok so i just got my new rebuild in and am ready to fire it up. I turn it over and all i hear is the good sound of great compression 
so i check my primarys by holding the rail and pointing the injectors up. i get some fuel out of #2 about once every 5 seconds. My plugs are all broken and look nasty so im thinking no big deal and go out spend $10 for a new harness come back and plug it up this time i get no fuel from any one. i can see on my old harness the injector plugs where red these are a brownish yellow and this new harness has a plug for a resistor relay that i did not have. is this relay my problem? what all effects the injectors opening ? and why are the harnesses different when both cars are s4 n/a?

Lives on the Forum
if the connectors on the "new" harness attach to the injectors without any drilling, sawing, or dynamite, then it should be good, I THINK...hmmm, list of anti-injector things...
1)40A EGI INJ fuse (engine compt.)
2)main relay (should be good if you're getting spark/ tach movement)
3)harness ground at the top of the rear rotor housing (under the 12mm bolt)
4)engine-to-firewall ground (at the back)
5)ECU

Thanks wayne
1)40A EGI INJ - its good
2)main relay - i get spark no gauges move but thats another problem
3)harness ground at the top of the rear rotor housing - got it bolted to the int housing where the egr would be on a 6 port
(4)engine-to-firewall ground - i have one from the bell housing to the firewall
5)ECU - ecu i got from 1revvin7 on nopistons and he says its good
How could i check to see if the injectors are clogged ?
would a bad afm have enough of a effect to not let any fuel through the injectors
