Okay, so I have been having trouble with the truck recently. If I let it sit longer than a day, I have to cycle the lift pump to prime to get the truck to fire. Takes a couple tries before it will fire too.

If I drive it daily, no problem. I've posted recently about this sort of problem.

Today, I primed by cycling the lift pump doing a bump start. Cranked and tried to pop off once. Every time after, no go.

So I primed 3 times no go. Then I cracked the injector lines and primed multiple times, no go. I've done everything I think of to try to get it to fire. I have fuel supply to the injection pump, but anything after the pump, dry.

Scan gauge show no codes. Is my injection pump giving up the ghost?

When you say sealing Washers are you talking g about the copper washers on end of injectors that seal injector in THE BOTTOM OF INJECTOR BORE???  

No. The sealing washers on the return fitting on the back of the head.

The trucks been doing pretty good. Although it has not Sat more than a day at a time, so it's hard to tell at the moment if I'm still having the problem.

I have noticed that my fuel pressure has evened out. I replaced the lift pump back in winter and the pressures sucked. Worse than before replacing. I would see a 6psi or more fluctuation.

After bleeding the injectors, pressure has not had as much a swing. I dunno what odds going on...

When I get the chance the truck will be put down and I'm going to tear into it and get things fixed,etc. Maybe I will find out then...
