Help 85 F250 6.9 wont start

^He said he was getting fuel to the injectors

Sounds like air intrusion to me. Fuel leaks down after it has sat for a bit. Twist off the fuel filter and see if it is full or not. You should hear a little "psst" sound of the vacuum release and filter should be to the brim with diesel.

Oops, I may have misread... Did you say it won't start when warm, but fires up right away in the morning?

White smoke out the tail pipe when cranking and no start. When engine is cold. As in waiting till next day to start. It will fire right up after turning over two or three times. Once it has been run and at operating temp. If you shut it off and then restart it right a way starts fine. let it sit for 5 min or longer and it will just crank and crank.

I'm confused by the punctuation in this statement...

Better?
I'm still betting heat soak.

I already contacted RockAuto and they are sending out a new IP. Lets see if it solves the problem.

I checked power at the IP and its good.
I am also going with the heat soak problem. I already have a different IP coming. I will see if it help with the new one coming. IP that is.

The new IP came yesterday. I had time today to work on the truck. Got in there and replaced the other new IP. This new IP took care of the starting issue when at operating temp. I've got changing the IP's out down to a science now Took me only 1 1/2 hour to get the job done and the truck fired up. I will be timing it tomorrow with my neighbors Kent Moore J33300.

Good deal. Now start saving for a moose pump.
It's not if it happens again, it's when. And it will.

If it was my truck I would have done that. This is my dads truck. When I first bought my truck. The 1991 f350 I did not know about Mel. But when the time comes I will be getting one of the moose pumps.

I'm glad Rock Auto took care of you though. Cheap pumps aside, good customer service is key.

 

[FoolhardyIDI]

Right, with out good customer service they would just lose business.

When you attempt timing the engine with the J33300 and have some questions pm me and I may be able to help you understand whats going on. We do have others here that can help when using the kent moore meters. They really are a built proof meter.
