at a complete loss, cracked injector nuts on all cylinders except #6 ( must be some special tool to get this one ) and have fuel leaking at all except #2 when cranking. not sure if it's enough to make it run though.

cannot believe it is a fuel problem now

this is refering back to original 99 will not start

 

Well if you have that many cracked and the fuel delivery and VP are ok you should have a substantial mess under the truck by now. My internet blindness is saying your VP has left the building.

 

I agree.
It's time to start finding a replacement IP.

 

Get the codes, guages, a new IP & a new LP.

You'll be set!

 

Try to find those nuts on a ford, no pun intended. Besides, there's two more of 'em. I hope I don't get booted for this one. Get your mind out of the gutter and back under the hood.

 

A 19mm or a 3/4" "crowsfoot" is what you need for the rear injector. I bought a 3/8" drive crowsfoot for $12.00. It's still not easy, but it works.

The "line wrench" type like this one works best, but you may need to grind the opening up a bit so it goes over the injector line. They make them in a regular open end type but they are harder to use for this job.
