Doesnt want to start
Hey guys I need some ideas.
When I try to start the engine when it has sat overnight it doesnt want to start. I am not getting any codes either. I will crank it for 15-20 seconds and have a huge amount of white smoke. After a do this 4 or 5 times it will start. It just doent want to "ignite". By the way it is getting into the 60's at night (burrr)
The glow glugs were replaced about one year ago, new napa GPR replaced about 2 months ago. Just replace the CPS a week ago, I thought it was the problem because I got a 0344 code from it. It would fire right up this whole winter when the temp was in the teens. Where should I start looking? Thanks

still sounds like a glow plug issue. try jump the two big terminals on the relay then start it and see if it fires up better. jump it with a screw driver or pliers and hold it for about 1 minute. if it starts good your glow plugs are good but your relay is not working correctly. could be the relay itself, signal to turn it on or a connection on one of the four terminals.

I just jumped the GPR for about 1 minute and no change. fired on the second try but really did not want to, had to keep the starter on before it would stay running. It 75 degrees out. By the way after the first hard start of the day it is normal, cranks right up, even when the engine cools off. Engine oil is right in the middle of add and full.

maybe the high pressure oil reservior is leaking down back into the crankcase. let it set for the normal amount of time and then pull the allen head plug out of the top of the reservior and check the oil level. it should be nearly full. iif its not fill it with oil and see how it starts then.

I dont have any allen head wrenches
. What would cause the HPO reservior to leak? If I did fill it and it started fine wouldnt it just leak down again? I'm no mechanic but I do need to get more tools! This issue happened out of nowhere, it just started doing this last week. When it does try to start it will fire a couple of times but I have to keep the starter on longer for it to actually run. Oil pressure gauge went up. Tach worked showed about 200rpms.

i am not sure exactly what is in the HPO reservior but low pressure oil is pump up there by the low pressure oil pump then is futher pressurized by the HPOP. but i would guess there is a check valve or something. also could be a leak letting going into the timing cover or maybe an issue near or at the injectors that let the oil drain down but if that much oil were to drain you would have to crank much longer than you are. maybe somebody has had the hpop reservior off and knows what is under there. mine will be coming off next week as i have an external leak.
filling it will simply help us figure out/ verify the problem.

Thanks for helping diagnose this problem, I bet it is hard to do without seeing the truck and knowing what it is doing with your own eyes and ears. So there is a low pressure oil pump that fills the HPOP resovior? I will go buy some wrenches tomorrow, do I need std or metric? Also I remember someone saying that the IPR could be loose, I think that was for a rough idle (which I have), but could that cause a hard start too?

Hey 1997F-350
You were talking about a loose IPR a while ago, what did it cause the engine to do? Do you have any ideas what could cause this hard start. It will start, but not very easily. I might have to buy both metric and std sets to be able to take anything apart on this thing

i'm on my second napa gpr in 4 months
. they fry easily. when i find the place that sells the stancors i am buying one. with a correctly working gpr your voltage meter should be down to 9.
the ipr is on the back of the hpop. it has a tin nut on it that holds the solenoid on. they sometimes come lose. usually a hard start when hot is when you start looking at ipr orings.
tj's right about the check valve in the hpop res. i wouldnt look there until you rule out the gpr and the level in hpop after sitting over night.
"""""I will crank it for 15-20 seconds and have a huge amount of white smoke. After a do this 4 or 5 times it will start. It just doent want to "ignite". By the way it is getting into the 60's at night""""
my truck did this also. when i had gpr issues. below about 65-70 are trucks have a helluva hard time starting w/o gp's due to the low compression(17.5:1) our psd's have compared to other diesels..
to have white smoke which is fuel you gotta have OIL pushing it out of the injector so i wouldnt sweat the oil system.
this is what i would do:
either buy another napa cheapy gpr or a stancor.
check all plugs, vc gaskets and uvc's.
ohm the gp's (you did replace with ford zd-11's when you did it right??)

I jumped the two posts on the GPR for about a min and tried to start it and there was no change. My voltmeter is around 9-10. It will start all day long just fine but if it sits overnight it is a pain. I will try to check the HPOP res tomorrow. So there is a check valve that could allow oil to drain down?

ive added to my above post a few times.
"So there is a check valve that could allow oil to drain down?"
yeah but just check the level tomorrow morning before starting. bum a allen tool from a neighbor.

what is a uvc?
The dealership replaced the gp's so I would hope so.
"my truck did this also. when i had gpr issues. below about 65-70 are trucks have a helluva hard time starting w/o gp's due to the low compression(17.5:1) our psd's have compared to other diesels.."
I started it today and it was 75 out, and still took a long time to start
