Last week I was driving and my 7.3 F250 shuttered like it sucked up some water. After a few seconds it went back to normal. I have been noticing the fuel pump getting louder and vibrating. I changed it out. It pumped up like normal and shut off when up to pressure. I then started the truck. It started fine but was missing out. I let it run a few minutes to let air work it's way out if any in there. Came by next morning and tried to start. It turned over but would not start. The pump ran continouslly and didn't sound like pumped up any pressure. It filled the water separator but would not start. Any suggestions?

 

Are you getting any smoke out of the exhaust while cracking? if so what color?

 

It put out a big puff of white smoke when it started no smoke while cranking

 

Do you have a scanner

Does your tach move while cracking?

 

I just tried it and it started blew out a puff of black then white missed for a few seconds and then leveled out, went for two or three mile drive and it seems to doing fine for now.I do have a scaner and it said pass. Thanks I'll be back if anything goes wrong

 

I drive it and let the engine get to operating temp and just floor it a few times

Yup just drive her like hell for a few miles after she's warm and see if the bugs work out of her.

 

i'll take out on the freeway, it seems to be okay for now , still worried about the fuel pump running continously.

 

You need to check fuel pressure at the fuel bowl to make sure you have good pressure, cause if not you need to back track the problem to the origin.
