I parked the car then came out the next morning and it turns over but no start. I check everything(compression, spark, timing, fuel) and long story short it turns out that it is flooding, fuel pressure is good, cts and maf checks out and no problems with the wiring harness.

The only way I can get the thing to even pop and sputter is by pulling the fuel pump fuse and cranking it, if I put the fuse back in it stops poping with in about 3 sec of cranking. If any one has any ideas of what can be causing the thing to hemorrhage fuel I'm all ears.

Also I'm running a larger turbo with deatschwerks 740's, z32 maf and enthalpy tune, all on a s14 sr.(wc ecu)

check your o-rings by removing the rail and turn the pump on you will notice fuel dumping if it is the issue...I have deatswerks 740cc injectors, z32 maf and GT2871r with emance tune that is doing a very similar thing except my injectors are not leaking so I am now going to suspect that the fuel I smell isn't igniteing due to a faulty starter signal wire....this thread might help you too zerothread/328569

by the way that thread worked for me, led me to a blown fuse for the starter signal wire

I checked that after I pulled the plugs and noticed that number 2 was a little black where the rest were starting to turn a little brown as they should. Number 2 injecter had a very slow drip, so I changet the oring and solved that issue.

I found that thread and looked into that, I'm getting voltage to the ecu at that pin when cranking.

Thanks for the help.
