hard start
 

my 99 7.3 wont start if i let i sit outside over night even pluged in, but if i put it in the garage it starts just fine and the garage is just about as cold as lettin it sit outside:humm: any sugustions on what it could be.

batteries going dead? sounds like the batteries are weak after the wind hitting em all night long, cause u have to have so much oil pressure to get fuel to injectors, if your truck isnt cranking fast enough you wont reach the 300 or so oil psi

its got two brand new bateries in it. i thought that to but it didnt help, the block heater heats it up in the garage but not when i leave it out side.

weak glow plugs, or glow plug relay? getting to cold and the glow plugs not able to heat up enough? the cold wind could cause problems, it sucks

thats what i thought im going to change them tomorow, what kind would you sujust

ive asked and people say there aint no better than the stock motorcraft glow plugs, they arent cheap tho, around here there 12 a piece, i ordered mine, im low on money so i did research and i found out that diesel rx are almost the exact same they heat up to 800 degrees, they run less than 10 a piece

thanks for the info. i apriciate it its a pain when you have to go some where and your truck dont want to start.

yup i know how that is, i cant drive mine till they get here cause it wont start :dang: so im driving a chevy blazer :scare2:

that aint no fun i had to tow mine 6 miles on a tractor with nocab in th snow to git it to start

damn, when my cps went out we had ta get the ol case out ta haul it to the farm, in 2 or 3 feet of snow, lucky us it was the 970 which has a cab
