5.8 liter engine. At home I park on a angle part on the drive and part on the grass so my wife can get out in the morning. I work at nights. The problem started after I changed out the air bypass valve and installed a new fuel filter. I used to be able to turn the key on and the truck would start ok. Now, If I miss hitting the gas when the engine first turns over it takes a long time to get it to start again. It doent matter which tank I have selected either. Once it gets warmed up and I leave it appears to choke a little after leaving a stop sign. Once at work and make the trip home it starts fine. Each time I try to start it I cycle the key off/on to activate the fuel pump again and it takes several tries to get it to start.

I'm having the exact same problem with my f150, even down to the cyclng the key on and off. I was wondering if you ever sourced the problem or not?

As silly as this may sound the cure was quite basic. I changed the distributor cap and rotor. Added a new fuel filter and stuck in a bottle to clean my injectors. Seemed to work for me. Good luck.

The injector wires can be connected either way.
