Today i installed a new hpop in my early 99 and now its having some trouble starting. Its taking a about 7-10 seconds to start but when its running better than it ever has before. While the fuel bowl was off i also shimmed the fuel pressure regulator with a BB. i dont think that would have anything to do with the excessive cranking. What do you think?

This is your problem. Remove the BB, your AB injectors will be happy.

Not only that, but how many miles have you put on her since the install?

Last time I had my HPOP off it took about 10 miles and 3 or 4 restarts to get her to run normal again.

Best of luck budd!

so the BB was a bad idea. ill take it out. I drove it about 15 miles after the install and restarted it about 4 times since then.

When did the FPR shim start causing starting problems? I personally have shimmed the FPR over 10 trucks and they all run and start just fine. Or is it just an AB injector thing? :crazy:

I'm not sure what it is. My truck did the exact same thing. When I checked the fuel pressure, it was over 75psi. I did it to my friends truck.. same thing.

I did notice one thing. It started fine when cold, because I let the glow plugs cycle. The pump had already kicked off. When hot, jump in and hit the key.. looooooong start.

I have a (I think) late 99 with the 7.3 L and have had a progressively hard(er) start problem... I've replaced the GPR with the industrial 200 Amp unit, and the Cam Position sensor has also been replaced. New batteries, etc... But every day the engine gets a little bit harder to start every time... It's only slightly better when warm. I've been reading about this HPOP problem where the oil in the reservoir drains down, and replacing a check valve solves the problem(?). Can someone here confirm this and if so, where the valve is located? :dunno:

Thanks!

p.s. ...what the heck is a "BB" ?? (I'm assuming this isn't referring to a small spherical metal ball used in my old Red Rider BB gun... )
