What brand of MPFI? What is your fuel pressure?
The CPI or SFCI is very critical for fuel pressure. Did the kit come with a pump?
The CPI unit has a minimum fuel pressure of 55PSI and typically wont start at 50PSI
I assume it came with a distributor. Are you confident it is triggering injector?
A test light would be easiest. Do you have the wiring schematic that came with engine? If not I can get an idea from a CPI engine. How many wires hook to injector?
