If it's taking a long time to crank then there is probably another leak in the system. You may try looking at the fuel pump seal as well as looking through the lines going from the fuel tank to the injectors to check for anymore leaks.

I have the same problem with my truck ! lol ive done the fuel pump, plugs, wires, cap, rotor, fuel pressure regulator, rear 02 sensor, tps, iac motor, crank positioning sensor, and i think thats it lol either way, i still have the problem. it does it when it sits for more than like 20-30 mins maybe..? but if you ever figure it out, id be glad to know what the trick is lol

you will think im crazy but unbolt one side of your fuel rail and bolt it back down should give you 1 start with no pedal assist then go back to its bullo sht cranking.

I am beginning to think I have a hole in the straw some place and the pump is air raiding the fuel before it sends it down the rail.

makes me feel good I am not 100% alone on this issue. I too replaced all 3 manifold sensors fuel pump plugs cap rotar cam sensor 02's o rings like wtf!
