So i have 1999 k1500 4x4 with the 5.7l vortec. I have installed the following within the past year (alternator, fuel pump, fuel lines, fuel filter, distributor cap, plugs/wires, starter, ignition switch). I just did the mpfi conversion and now the truck won’t start, the truck ran and started fine before i did the conversion but with a po304 missfire. I’ve double checked all the plugs twice. The only thing i think it could be is the fuel pump relay but it worked just fine the day before. Thank you for any help, i couldn’t find a thread with my same issues so i created this one.
