No cold start without starting fluid and will not rev up at all until warm??

[slopoe]

I just purchased a 99 f250 has 300k miles on the only way it will start when its cold is with starting fluid and will idle rough and die several times until warm you also cannot rev it up at all until it warms up any help would be greatly appreciated.

Yeah was actually on top of my list of things to check in the morn thanks for link

Winter Operation, Hard Starting, Hissing Sound Etc...
Good one here too.
Also what kind of oil do you run and how cold is it?

good idea and u might want to check the glow plugs with what strokinearly99 said in step 5 .. it sounds more like a gp issue that a gpr issue i just replaced the gpr and im replacing the glow plugs this week ... if u need glow plugs go to oriellys they have good prices and if u need a gpr go with the stancor

also try starting it with the bullydog off ... that could (doubt it but could) be adding to the issue ... i know starting mine in stock mode makes it easer to start when it drops below 20-30 ish

Just a quick thing. Try to get Motorcraft plugs. Other plugs tend to swell up on the tips and stick in the heads

Have you checked your battery connections? They could be dirty.

Oh I didn't know they sold the Beru's. Good to know

That would cause slow starting and maybe cranking but no start. That's always a good thing to clean anyway.

To the OP, the part about not being able to rev it up is because of the EBPV. It closes to help warm up the engine faster.
