It is very difficult to fix a car over the phone or internet. However, I will give you one possibly problem you may. It sounds like lack of fuel to me.

 

Get a fuel pressure guage and ck pressure at the fuel rail.

 

When DIYs install 255 pumps, occassionlly the supply tube falls off or it fits very loose and the engine gets only a small amount of fuel or non at all.

 

drop the tank and ck the fitment of the tube to the new 255, most likely that will be your problem. if you continue to have problems, feel free to call me at my shop at 740-964-3503.

Quick and easy check. Grab the injector harness and wiggle it with key on. Listen to and see if you here the any clicking. I know it sounds stupid but my car would do the same thing. The injector harness had a short in it somewhere

Awesome....I have to fore-warn you though, I can only do cars up to 2000hp. That thing looks like it might just break anything you stap it to.

 

 

Realistically it should be around 650 to 700, anymore and it might put the crank on your floor. "Stock block and pump gas"

 

Sorry to hijack thread
