90 F250 7.3 idi COld/Hard start...HELP!

[UNDERCOVER_73]

SO my grandpas 90 7.3 idi is having trouble starting when its cold, he said it would take him around 2 minutes of cranking b4 it will even start.

but when its warm it starts like normal.

My guess is its The Glow plug relay, OR the glow plugs....anyone ever had trouble like this b4???

Im trying to keep the Blue Oval in the family

any help would be great ....

Definatly not a glow plug problem. Let me guess, the longer it sits the harder it is to start.
What you have here is a classic "idi air intruson" problem. The truck is loosing it's prime. air leaks in and the fuel runs back to the tank. then you spend a couple minuets pumping fuel back up to the injection pump. Thats a good way to burn upa starter quickly. Then the weak starter will not spin the motor fast enough to crank it right away either.
It's commonly the rubber lines and/or the o-ring under the plastic caps on the injectors. The repair kit's are pretty affordable from many different vendors.
Mine ended up being a check valve inside the fuel lift pump. And another new starter. After i did my lines and hoses first, and that still didn't solve my problem.
Do a search and you will learn allot about that classic Ford idi problem.

Figures, a day late and a dollar short.
I've been fighting with mine for like 2 yrs. Just recently threw in the towell and finally found a local shop that could work on the "Old Diesels" that arn't plug and play.
Money well spent! Cranks right up after sitting more than a day. FINALLY! Now I an put a bed on it and put it to work!

Dually is a 97 powerstroke auto 2wd with 210,000 on it. I use to own it and sold it to a buddy that lets me borrow it anytime i need it. He pulled the 4.10 gears and put in 3.55's to streach it's legs and drop some rpm's.
I would've bought it back except I need a 4dr 6 seater now with my new larger family.
It actually has a full "Choo Choo Customs" package on it and inside and out. Body colored running boards, air dam, visor, tail light covers, even had body colored vent gaurds, plus leather and wood grain inside. It needs a repaint, but thats what he dose.
