Ok so thank you first to dDub for all his help in answering my questions as I have worked on this S4 NA I just got. Now though I have come to the true problem behind the non starting and it is the wiring. There is no continuity between my injectors and the f-32 main relay nor to the computer. I would like suggestions as to any aftermarket harnesses and or places to purchase harnesses. Also if there is anybody of mention near the Reno, NV area that can help me with the install or would be highly recommended to do the install please do tell.

I have a S4 NA ECU wiring harness laying around, if you need one...

It would be truly amazing if all 4 injector runs were open (considering each injector has its own wire to the ECU) to the ECU- are you SURE you've checked all of the connectors? Do you have any voltage at all on any of the ECU pins for the injectors with the key on?

monday I have eight hours that I will put into making damn sure but here is what I have done so far. First off I finally discovered that something to do with the injectors was the problem when I was able to manually atomize gasoline into the injector ports(with injectors removed) and then crank the engine and have it fire till it burned that small amount of gas. I've already checked the fuel lines and there is significant fuel pressure and flow. Thus I first thought bad injectors. So I pulled the injectors and tested them on a car battery and they ohm meter and they all tested good. Built up a quick home made flow checker and all sprayed freely when manually powered. Reinstalled, tried again, no change. Thus I came to the wiring and ecu. First off I reffered to the wiring diagram and located and double checked that the injector are wired direct to the ecu. I then tested the secondary injector wiring to the ecu thouroghly only to find a lack of continuity. I then turned to the ground. Checked straight from the injectors to any grounded object. Nothing. Backed up to the only relay that the wirign goes through. Nothing input or output. Bypassed the plugs to test for the possibillity of cold or broken solder points. NO continuity what so ever. That is where I decided to call it a week and close the garage till monday.
On a somewhat related topic I am curious as to why I cannot get my alarm to arm. Could these two be related at all? Mind you this vehicle has not been broken into or stolen before and the starter still cranks.
