you need a walbro 255 fuel pump atleast, HOWEVER the stock fuel pump would not cause your car to not start.

have you checked to see if it is getting fuel? is it getting spark?

ran same set up with no injectors untuned, ran fine except the car would take a **** after the beating, the walbro 255 installed ran a lot smoother.

if the basemap is good, then yes.

if it doesnt start then, put the stock injectors back in it with the stock ecu JUST FOR START UP.

before you do anything.....check to make sure the car is getting spark, and make sure it is getting fuel. any CEL's?
