is it getting gas?
try cranking the car with the plugs out and see if your getting fuel to the motor

do you have a wideband? a single wire 02 sensor can only see from 14.5 -14.9 afr.....doesn't tell ya much.

But I would try and diagnose the fuel system, sounds to me like something is messed up on the delivery end of things

ya know i was thinking the same thing ... only problum is ... getting my fuel pump out is impossible ...... and when i checked my plugs after the car wouldnt start they were bone dry .. and i mean bone dry ...... but to me it doesnt seem like somthing major ...... because injectors dieing usualy fail open .. not closed ... causing a flood ... im praying to god that its a cloged fuel filter .. but i cant seem to get my fuel lines off ... i tryed for 2 hours today and they just wont budge

Do you have spark?

Have you checked for 12V at the injector plugs (with the key on IGN)?

If you don't have 12V at the injector plugs, the injectors will never fire. You NEED a multimeter. $10 at Canadian Tire.

Sounds like you have an electrical problem. Check the EGI fuse.

egi fuse is fine ...tryed to do the remove and crack thingy b 4 i took the plugs out and nothing .... that and the fuse is still whole not blown .. and yes i do need a multi meter ... so you are sudjesting that im not getting 12 volts to the injectors hmmm ...... by any chance could my problum be caused by my safc ?.... ive been running with it for nearly 2 months not with no problums .. but after the first time it died on me i reset all my tunings to 0 correction for fear that i was starving my engine of fuel .... either way .. i have an safc .. and have had no problums untill now ...

start with the easiest stuff - figure out if your pump is pumping:

jumper the plug under the hood (can't remember which one)

if the pump is pumping, check your filter

just start working your way down the line of fuel delivery until you find your problem

maybe a wire from the safc fell off, or the conection to it is bad now.....
location would help too, so that someone near by could help out

You don't have to touch the fuel pump at all. Find the hose that runs from the top of the fuel filter to the pipe beside the oil filter. Disconnect it from that pipe and stick it in a deep cup, like a large Tim Hortons cup. Make sure it isn't going to fall or tip over. Now get in the car and crank the engine for 1 sec. Get out and look in the cup - is there gas in it or not?

make sure your checking the correct 2 wires at the fuel tank connector.

1 wire is the ground the other 3 wires go to the pump, fuel level sender and low fuel light on the dummy lights.

if the car is not running you should get close to if not 12V (depending on battery charge of course which may be low now that you've been cranking over toi get it started).

Note that unless you use the jumper wire on the (i think it's yellow) 2 prong connector near the stock airbox, you will only see power at the pump for 2 - 3 seconds at most when you turn the key to the second position. Otherwise you would see power during cranking.

Need to be clearer than that or he'll never find it. And he has an s4...

The plug will be hanging off of the harness, below and a little astern of the variable resistor. The thing is, the plug is covered by a black rubber boot. So don't look for yellow, look for the boot. Find it and pull the boot back - is there a big yellow plug there? If so, jumper it.
