Ford Super Duty (1999-2016) :: V10 Won't Start When Cold
Oct 31, 2016
I'm having a problem with starting the V10 in my 99 E350 cube van. It refuses to start when cold unless I stick my finger in the idle air control valve and force it shut, or use starting fluid, or a combination of both. Once I do get it started, it will die if I touch the throttle, but once warmed up, it runs fine. I have replaced the IAC, the cylinder head temperature sensor, the fuel filter and fuel pump, and cleaned the MAF. My code reader shows no codes, and like I say once warmed up it will run fine and restart no problem.

I normally just troll the existing threads and find what I need, but I am stumped. Just had the HPOP replaced and ran fine for 2 months. Then I started getting a hot no start. So it sat for a couple of days. Then I went to pull it in the shop, it started, I backed up 10 ft and it shut off. I started it back up and it died. I am going to hook it up and figure out my AE software tonight. So question, can an IPR valve get clogged after the fact? Or could it be a bad HPOP?

Truck: 1999 Ford Truck F 350 4WD Super Duty V8-7.3L DSL Turbo VIN F
Problem: Especially when it is cold outside . . . The truck takes forever to start and while doing so a ton of white/grey smoke comes out of the exhaust.
My starting schema: Turn the key on have the gas pedal pushed to the floor until the "wait to start" light goes out. Then, I turn the key off and back on while still pressing the gas pedal all the way down. When the "wait to start" light goes out again I remove my foot from the pedal and try to start it. I never leave it cranking for more than 5-7 seconds. If, after trying this process several times I will not push the pedal in at all. Also, sometimes I will leave the pedal pushed in while I am cranking it over.
The truck used to start after a couple of tries but lately it won't start at all, even after 20 tries. Sometimes it will spin up for a second as if the engine gets going but then just doesn't continue running. When it is warm out it will usually start after a few tries but doesn't seem normal to me. After I first bought the truck(used) it would start up within half a second after turning the key.This all started after I had to fix an o-ring that was damaged on the top/back of the motor that was dumping all my oil out of the top/back of the motor.

I have a 2002 f250 superduty 5.4 4x4 around 317xxx original motor and trans. When it's cold out it won't start at all I have to use starting fluid but once started it will start right back up. Did the plugs fuel filter cleaned the intake and sensors still have a problem plenty of fuel pressure plenty of cranking amps brand new battery and Alternator. It just cranks and cranks when it's warm out fires right up. Runs smooth no lack of power or misfire no codes are being thrown also.

Here's what's happening:
I can have it on hot and be driving along, then it will start blowing cold air. I can move the temperature switch to cold then back to hot, and it'll start blowing hot air again.
Need to know if that would be temp or the motor? I don't want to just change parts randomly.

I'm looking to buy a 08 f250. It has 70k miles on it. The guy is running a mini max tuner on it. I did notice on a cold start as soon as he hit the acceleration it had alot of black smoke. Is this normal? And is there anything I should b aware of when looking this truck over.

05 6.0 72,XXX miles. Will not start when cold (below 40ish) outside and engine is cold. Throws a P1378 code and no others (per the BullyDog Gauge Tuner that came with the truck). Checked the FICM with the voltmeter test on a morning it wouldn't start. Never dropped below 48 volts through the whole test. I can clear the code, try and start the truck and it comes back as soon as I try to crank it again. Warm days=no problems at all.
Oh yeah...I did go through the harness from the FICM to the injectors a while back and found a couple spots that were rubbing on various bolts. Peeled the insulation back and taped up the bad spots to keep from grounding something out so I don't think it's a harness issue. Also found a ground wire off on the back side of the FICM and reconnected that on the nearest valve cover bolt.

I picked up my 05 F350 dually 5 speed w/ the 6.0 powerstroke motor in august... It only had 38k on it when I bought it... its got 43K miles on it now...
Ran great in the warm weather but ever since it got cold out its been a struggle. It was running rough on the way home and kept stalling while i was driving it.. (acting like it was starving for fuel).
I went and replaced both fuel filters and started the truck... let it warm up and it stalled while sitting in my drive way and haven't been able to start it since...
I have fuel additive in it but since I don't drive it all the time (maybe 3 times a week for 30 miles) could it be possible that the fuel is gelling?
I was going to check the EGR valve tonight...

2002 7.3 running rough.
This is my symptoms : On cold start ups engine runs rough. Idling it knocks worse than normal on the road she runs really rough. If I get on here she smooths out ( but still runs rough a bit) but normal driving at between 1200 -2000 rpm she runs so rough it shakes the whole truck. It will do this until she gets up to operating temp & then it goes away. The more she warms up the better she runs.
Once up to temp she will run perfectly. The colder it is outside the worse it is & the longer it takes for it to go away. I have replaced the valve cover gaskers and new harnesses, new glow plugs. Still same problems. I have AE and one time it gave me a #2 cylinder code. have not been able to repete this code. What to check next.

I changed the IAC valve 2 months ago because my truck kept stalling when idling down on a cold start and that fixed the problem. A few days days ago when starting it started revving to 2 - 3 K and won't IDLE down now? I changed the IAC again and that didn't work. What else should I be looking at to stop it from revving so high?

2011 SD 6.7 with factory remote start will start normally when the temperatures are above 20F or the vehicle is warmed up. If the temperature is near or below O F and the vehicle is cold soaked for 12 hours the remote start fails to work. Push the lock button and the lights flash, push remote start twice and the lights flash once and nothing happens. Subsequently can manually start vehicle with key without any delay or problems. Once vehicle is warmed up can remote start normally. Only recently have the temps been low enough in the area to experience this problem which has repeated 3 times. Unable to find any troubleshooting in the service manual for this.

My 2001 6.8 L V10 runs great all day & night without issue, but first thing in the morning when below freezing it has a hiccup. It'll fire right up and stutter and stall within less than 2 seconds. Usually twice. Third time it fires and keep running. Is there a fuel check valve somewhere on this thing? Not sure what that would have to do with the temps. Wondering if it's/there's an easy fix or not?

I have a 2003 F450 PSD which won't start cold. I leave it plugged in overnight and it won't start in the morning without starting fluid. I spray a little while cranking and it turns right over. It runs really rough for a few minutes but as it gets hotter it settles down and runs like it's brand new.
Once at operating temp it will start up again no problem. I changed the GPs, the GPR, the valve cover gaskets and GP harnesses, 2 brand new batteries, oil change, fuel filter, air filter. I can't imagine what the problem can be.
I know the icp sensor is bad, I checked it and it has oil in it, but it still won't start unplugged so that isn't the main problem. I noticed it has a minor oil leak, not sure of where it's coming from, but it seems to leak when the truck settles.

My 2000 F-250 6.8L V10 has a choppy idle during the first 30 or so seconds after a cold start up in the morning then it smooths out and drives perfectly. If I were to place the truck in gear during the choppy idle, it would not die and throttle response would be fine.
I cleaned the MAF sensor and checked the PCV elbow for cracks (no cracks). It idles at about a 1000 rpm during a cold startup then drops to about 750 rpm according to the dash tachometer. The truck has 187,000 miles on it.

So, I have a 2007 f250 with the 6.0. When she's cold she starts fine but runs rough like she has a miss. When she warms up the miss goes away and it runs pretty good. But if I shut it off it won't start for about an hour or so.
ICP sensor has been replaced.
FICM is putting out 50v

Just bought a 02 f-250 7.3 with 115k miles. A couple days after I bought it I noticed a lot of white smoke on cold starts for about 20-30 sec at 50 degree temperature. So I tested the GPR which ended up being bad a replaced with the one that is double in size(name escapes me atm) and also did the 50 cent mod to keep the through-valve cover harness from losing connection since both sides were lose.
After that the temp warmed back up and it would only blow a "puff" of white smoke. The past two days it has gotten down to 30-32 and the truck has a rough time starting. Cranks fine but it's almost like it's getting choked or flooded then it will blow smoke for 3-4 minutes after it starts. The truck does have a FASS fuel system on it with stock injectors. Should I try to Ohm out the glow plugs again or where should I start trouble shooting?

Cold no start goes nowhere. I have a 2001 7.3 that will not start in the cold if I forget to plug it in....like last night. I have to plug in the block hater and give it a while before it will start. I tested the glow plug relay,it works fine. I can not find a test for the fuel bowl hear, and I'm not one to throw parts until I accidentally fix it. Any test procedure for the fuel bowl heater? Why this POS is so bad in the cold? Glow plugs tested fine at diesel shop in December, and this problem has been around since before that.
