Why Won't You Start?!?!?!

[RumRunner21]

New to the forum, and thank god i found it! Just bought my first Ford Diesel (01 Excursion 130k miles). Bought it to tow boat and trailers around, but has turned into my daily driver.

For some reason getting the Excursion started has become almost impossible. It took me 10 min to get it started this morning, and even when it is warm, it still needs to crank for about 30 sec. to get her running.

First guess was fuel pump, but when i turn the key on, the pump turns on and has pressure when i turned the fuel drain lever by the fuel filter.

Maybe glow plugs... was 75 deg when i tried to start it.

Wait to starts light comes on for 10 sec.
runs perfect once it is started.
reprogrammed it back to stock settings
no fuses are blown
cranks no problem.... just no fire


I have only owned one other diesel.... and it was a 93 dodge, with none of these craxy sensores on it. So i am a real rookie when it comes to these engines.

Any help would be greatly appreciated!
Thanks

Well it could be your GP system....but if it was that hard of a start at 75° Id say worn rings...Is it smoking at all? Amount of Oil Consumption? Blowby been looked at?

change the GPR and that might be it. would be a good place to start. u can also check it with a multi meter

[RumRunner21]

What is the GPR?
no smoke
uses no oil.... but i have only put 2k miles on it since i bought it last month.
Thanks

If not the GPR , I'd look into injector O rings and HPOP . Get it scanned with Autoenginuity and it will tell you what the HPOP is putting out while cranking. You need at least 500 psi for it to fire. Bad injector o rings will cause it to crank long .

GPR - Glow Plug Relay, its on your pass side of the motor, there are tons of threads on it. my truck was doing the same thing. changed that and it started right up. also when cranking it is any white smoke coming out?

You don't need Glow Plugs to start your engine at 75 degrees, might be much worse in the cold but it's something else....

Could your HPOP res be empty? Take the little plug at the top out and see where the level is, should be an inch or so down.

How does it restart? After an hour or so?

Does it have a K&N filter on it could you have low compression?

check the codes, if it is a 1212. You have air in the HPO system, bleed it and your good. our your ICP went bad.

It's been mentioned a few times, scan it and look at different sensors that will tell you what's wrong. Gotta be a good scanner to read any codes and even better to interact with live data.

[RumRunner21]

scanned it with two scanners and no codes.
checked the HPOP res, and it had fluid in it.... but there is no dip stick to determine how much should be in there.

Today it won't start at all (about 60deg out).... yesterday it took for ever, but once it was started and warmed up, it would fire up.... but not as fast as it should.

Thanks for the help.
