Ford Super Duty (1999-2016) :: 2003 6.0 - Intermittently Not Cranking
Jul 2, 2016
I have a 2003 6.0 Auto that has an intermittent non cranking issue. Once it does crank it fires right up. Usually when it doesn't crank, I just keep trying the ignition until finally something connects and it will begin to crank and then start. Sometimes I can try it twice, other times I may sit there for 5 minutes fighting with it. My only issue is, I need to get this problem fixed before it becomes a bigger issue.
I don't think it is the ignition itself. When I am attempting to crank I can see the window switch lights and other things going off when I crank it which I though was normal when the starter is operating.
My first thought is the transmission range sensor which I am trying to locate. I looked on the transmission itself which seemed to make sense but I wasn't seeing anything familiar. Someone hinted it might be under the dash above the brake pedal but I am not seeing anything jumping out at me.
I also question the starter itself, but I hear no noise coming from it at all when the problem shows itself. No clunk or anything. Which makes me think something is causing the circuit to not function properly.
The other thought I had is a possibility in the wiring somewhere. Maybe a bad ground on one of the batteries? I have a brand new factory positive aux cable so I think I can scratch that off the list. The batteries are also charged as well, but cannot rule out the possibility that maybe one is bad since I did not install them. But I can make sure they are both charged, and the issue remains. Where I should check?

My 2003 F-250 (gas V8) will always start right up when it is cold. However, once it has warmed up, it often will not start. Cranks fine, but not even wanting to start (like someone pulled all the plug wires) and has left me stranded until I wait for 3+ hours for it to cool back down. Doesn't trip the check engine light, but seems to be due to the engine being hot. What this could be?

I have a 2003 F250 with 157,000 mile. Left the house last week and got about a mile down the road when I realized I had forgotten something. Pulled off to turn around and had no power to get back onto the road. RPMs wouldn't go over about 1500. Finally got it on the road and it completely shut off. Was able to get it home and have been tinkering with it. Stats from Scangauge are as follows:
Key on not cranking.
IPR 14.81%
FICM 47.6-48.0
Sync=0
ICP 32
Data while cranking.
IPR 43-47%
FICM 38-42
Sync=1
ICP 1532
I'm leaning towards a bad FICM but the ICP pressure seems to be high to me.

I have a 2003 f250 super duty with a v10
i was towing a trailer up and down lots of hills and the battery light on the dash came on. there was no effect on the performance right away. as i kept driving into town i was starting to worry if i would make it.
as i pulled into the carls jr parking lot, the ABS light came on, all the gauges shut off and the truck died just as i pulled into a parking spot.
i figured it was the alternator, had it tested at AutoZone (failed twice) so i swapped it out for a lifetime warranty AutoZone one (very small town, nothing other than an AutoZone)
the truck started after being jumped but the battery light was still on. i figured that the bad alternator killed the battery. the battery was 4 years old and they usually only last 3 years in the AZ heat so i bought a new duralast gold.
the battery light was STILL on after that. the Autozone guy ran his test--- engine off- battery tested fine starting---he said something was wrong with the starter (but it cranked awesomely!) running--alternator tested fine
i just can figure out why when i drive down the road i dash light will turn on and off at random times. the truck seems to run fine. I've even been under the hood shaking the wire while i had someone watching the dash and i cant seem to make the light go on or off

Bought 02 350 DRW, started hard first day, now not cranking. Seen a post on neutral transmission switch and mine is not lining up, but need to adjust the rod out of transmission also? I was able to match lines on switch but with flanges on fitting it will move back out of place when moving it to fit in bolts.

My 06 f350 power stroke has a viper 2way remote starter.
When I try to start it when the truck is cold it doesn't crank long enough for it to start the truck. It will try 3 times when I hit the start button and normally won't go. It almost starts most times but stops cranking right before it starts. This is driving me nuts.
I just tried 3 times to start the truck and it in ally went on the 8th time trying to crank.

I'm in a real jam because my work truck won't start. 1999 F250 7.3 Diesel 157k mi. - Air and fuel filters were replaced in the last 500 miles. This pup ran fine when I parked it last Wednesday before the holiday.
Checked for start last night because I'd been having battery issues, Both were replaced the previous week. It's cranking good but just won't start, not even a bit. No wait to start light, oil level is good, can not get obd reader to link.

I have an 08 f350 lariat with the 6.8 with 66000 miles. A month ago took it to the dealer with a plugged catilityc converter. All covered under warranty. Got the truck back, starts great when cold including 18 degrees the other morning. I drive 7 miles to work, shut it off and restart, it acts as if the starter is struggling to turn the engine over. Once it cools off, starts fine again. I took it back to dealer, they replaced the starter. No change. Took it back again, they replace battery. Cranks a little faster, but you can tell it's still struggling. It always starts, I'm just wondering how it will be when it's 80 out and in pulling my 9000lb camper....

So, back in July I had some issues with my V10 F250 not cranking after a bad rain storm. (New battery was installed May 2011) and ended up recharging the battery & replacing the alternator. Have not had any problems since until yesterday as I was going to use the pickup. I drove it on Thursday with no problem and Friday Tropical Storm Lee came in with TONS of rain. Now NOTHING AGAIN. I also noticed a drop of water coming from overhead console (trip computer module that has not worked since I've had it).
So I pulled the overhead console out and water was beaded around the center overhead clearance light opening. I dried that one with a paper towel and looked under the headliner and others were slowly leaking. After looking the center one already had a drop beaded again. Would this cause a short that would drain the battery? Also having the battery drained so bad twice in 2-3 months is this going to degrade the capacity of my 5 month old battery?

I have a 2006 F450 6.0 Super Heavy Duty. The Problem that I am having is when I turn the key it wont crank over. In order for it to start I have to hold the key in the crank position (like i am trying to start it) for about 20+ seconds, and then it will start cranking over. After it cranks over it starts just fine no problems. This only occurs when I start the truck up for the first time each day. After the initial start of the day its fine. (FYI I turn the ignition to the on position and just let it set it still takes me turning the key to the crank position and holding it 20+ seconds).

I drive a 2002 F-250 7.3l and have been having a lot of issues. The most recent one is that my truck won't crank unless I've had the block heater plugged in. Like I said in the title, the batteries are supposedly fine. They've been tested by a mechanic and Advanced Auto Parts. But when I crank the truck, it will only turn over for 10 seconds or so before it loses enough juice to even turn over. So it's kind of cold, but only 40-50 degrees, so I didn't think the truck would have that much of a problem starting. I'm wondering if my issues are a combination of an electrical problem and a heating issue.

Went to run errands today, and noticed a slight hitch in the engine cranking... I'm on a brand new battery that isn't even a year old, so it seemed a bit odd. After running the first errand, the hitch in the cranking got a lot bigger and I noticed the voltmeter was reading lower than normal. In addition, lights, HVAC motor, radio, and even brake lights would move the needle. To me this says my alternator isn't working...at all.

2006 F250, 6.0, AT, 59K. Week and a half ago, started cranking slow. I charged the batteries and checked with a professional load tester. Both batteries good, but voltage was fluctuating and tester said charging system needs service (no battery light). I swapped in a remand alternator as a new was not available that day. It lasted 6 days and this time the battery light was intermittent.
I checked voltage and again it was fluctuating. I swapped in another remand unit and 3 days later, same thing, intermittent battery light and fluctuating voltage. I'm installing a new, not remand unit tomorrow. However, could a bad FICM cause this problem? I noticed that the engine seems louder (not the exhaust note) at idle. This truck is clean and I have no corrosion issues. What is the right direction to test the FICM?

2005 F350 crew cab with 6.0 currently cranks but no start with a P2291 error code. Using scanguage 2 it shows icp 0, IPR 67.7, FICM 47.5 while cranking. Disconnected ICP and still no start. removed icp and hooked up air and I do not hear/see any signs of air leaking. When I disconnect the air it then whooshes out. About 2 months ago got a #1 cylinder contribution error code and changed out that injector and it has ran fine up until this issue.
Can this be a IPR? I am leading towards the HPOP, but as it costs a pretty penny would really love to make sure I tried every other avenue.
I have 197K on it, and 2 years ago did a EGR cooler delete. In May this year replaced the oil cooler, and then in August changed out the #1 fuel injector.
Oil cooler screen was broken. Cleaned the entire reservoir out. Could this just be a clogged IPR? or seeing the change while cranking an indication that it is working?

ESOF not going into 4wd at all, except once in a blue moon... for a few times. All relays and fuses tested, swapped with known good units.
NO 4x4 light. so its electrical related. My hubs function like they should. when they are told to. I recently just swapped esof motor/gearbox on the TC. Worked 2x in the garage, went for a spin down the road, went into 2wd and stayed, wouldn't go back into 4hi brought it back inside, dinked around with resetting the GEM fuse. started working good. drove around and switched in and out of 4wd like 20 times no issues. next day, tried to go back into 4wd. nothing. Bring it back in the garage.
CURRENT DIAGNOSIS: Siting inside right now, If I flip the switch, I don't get anything. normally, that triggers the vacuum pump to suck hubs in. That doesn't turn on, the relays under the hood don't click. so it seems I am back up to the switch or GEM, or wires between.... Any test layout for how to test the switch in the dash? seems to be fairly simple, but I just wanted an exact view of what i need to test.

I have a 07 F650 crewcab with a Cat engine. The air-condition and heater fan work intermittently no rime or reason to it, be driving down the road and it quites, then maybe a few hours later and it will start. A few days ago my wife turned on the key and the fan was working and then yesterday she turned the key on and it wasn't. When I bought it I watched them replace the fan and it worked for a few hundred mile then stopped, for the rest of the trip it was on and off. I replace the resistor and spliced on a new electrical connector, but still have the same problems....

I have a 2011 F250 6.2 xlt 221k miles. I have an issue where my AC works sometimes and other times it doesn't work. On the occasion it will work kind of, meaning that it will blow cold for a few seconds (when the compressor clutch engages, but as soon as the clutch disengages I get warm air. My low pressure is at about 30psi and the high is about 140psi (seems low to me). When I bought the truck the a.c. didn't work at all. I pulled a vacuum and put the recommended 29oz of 134a in it. When it works its VERY cold. There doesn't seem to be any ryme or reason (temp, humidity, drive time) as to if it works or not. On occasion (not working) I have been able to turn off the a.c. for a couple minutes and when I turn it on it works.

ABS light has been coming on intermittently the last few days. Checked the resevoir for fluid level...topped up a bit. Changed the oil today and looked at the sensor connectors on the front brakes...ok... Got a new speed sensor and installed it....ABS is still on. Checked the old sensor with my meter and it is open circuit....no continuity, so I'm thinking it was the problem.. Is there something that has to be reset for the fault to clear, say with a code reader etc?

My fan control went out yesterday (hot day with no A/C), It comes back on at times, but if it's on three it may only blow like it's on one. What I need to replace??
