Ford Super Duty (1999-2016) :: 2000 F250 - Choppy Idle During First 30 Or So Seconds After A Cold Start Up
Mar 26, 2017
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.

I have a 2011 F250 with the 6.2 gas engine. I have been having a problem that the dealership says there is nothing they can do and have never heard about.
After the truck sits all night I get in and drive it for 10-15 min. It gets warm and I get out turning it off. When I come back about 15-45 min later I start it up and go to leave. As I pull out and start to accelerate in first gear the truck goes to an idle for about 2-3 seconds. I push the gas pedal and get no response. After a couple of seconds it picks up wherever you have the gas pedal. If you have the pedal to the floor it jumps you forward. This is not putting on any lights and the computer is not throwing any codes. According to the dealership the computer is telling them there is nothing wrong.
This has happened 12 times in the past 6 months. It has happened since I bought the truck. I have just started documenting it as of 6 months ago. It is not something I can make it do on command. After it happens once it doesn't seem to do it again for a week or two. I have 31000 miles on the truck. The dealership has had it for 4 days now and can't seem to get it to happen for them.

I'm getting a really choppy low RPM drive. If I'm above 2-2.5k rpm it runs okay but as soon as it drops under 2.5k it starts to run very choppy and loses power and Boggs in and out of power regardless of how much throttle input I give it. I had a tune up done last year and a recent oil change...

6.2L F250 truck is just shy of 60k runs good however on cold startup there's now a pretty loud ticking noise for a short period (30 seconds) until it warms up then it slowly goes away. Once its warmed up there isn't much of anything.
Did these have exhaust manifold gasket problems like the 5.4? Hoping that's it if not, any other common problems that would make that ticking noise and then go away quickly once the engine is warmed up.

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 2000 F-250 V10 that misses (cylinder 10) at the idle, once you give it gas it runs correctly again. I am at a loss. I have replaced the plug, tried moving coils from one cylinder to another to see if it shifts the miss, and it has new injectors. What this could be?

I have a 2000 Ford-F250, V10, 6.8 liter Gas. The issue is that when I try to start the vehicle it will start, but then start to idle real low and then die. If I try to restart sometime it will and sometimes you have to let it sit. I can also pump the gas and it will sometimes start.

My 2000 F250 SD 5.4 AWD's A/C wouldn't blow cold suddenly the other day. I confirmed the A/C relay (engine compartment, 3rd down from firewall)was "clicking" but compressor clutch was obviously not engaging with dash switch on Max A/C and engine running. When I take of the 2 wire connector to compressor to see if it is getting power, the truck won't start..if I disconnect the A/C compressor plug while running, the engine similarly quits. I have never had another vehicle do this on me before..I could unplug the compressor on my Jeep GC, for instance, measure 12+ volts with A/C ON w/car running and no problem with Jeep engine turning off.
I have searched for A/C wiring schematic w/o success. I checked every fuse in cab/engine for continuity since I don't know which ones might deal with A/C..jumped hi/lo pressure switch connectors with engine running/A/C ON w/o compressor clutch engaging. Clutch turns easily, have banged it a few times, and air gap looks good. More bizarrerly, I hooked the compressor to a 12V/ground via its 2 male prongs and didn't get the clutch to engage.

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.

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?

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?

I just bought a 2000 F250 SD, 4x4, 5.4, Quad Cab. I drove it off the lot, stopped to put air in the tires, jumped back in and it wouldn't crank. All of the dash lights worked fine. Tried jumping at the starter solenoid and got nothing. Got under the truck and jumped it off the starter, vroom, fired right up. Replaced the starter solenoid and had no issues for about 2 hours. Then it did it again. This time it wouldn't start at all. I towed it back to the dealer and they had it for 3 weeks.
Then yesterday I called and they said it was done. Picked it up, drove to the barber shop, got my hair cut, came back out and it did the same thing AGAIN. After jacking around with the shifter and turning the wheel back and forth 100 times it started. The key is kind of hard to turn sometimes in the ignition, so I'm thinking that the ignition cylinder needs to be lubed real good, but that shouldn't stop it from cranking the motor over, right? I was going to swap out the ignition switch, but I don't know if that will do any good either.

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.

2000 f250 V10 ...
Problem: More often than not when the key is turned to run (?), prior to engaging the starter, the fuel pump does not turn on for its 5 seconds. I have installed a fuel pressure tester gauge to watch the fuel line pressure. It was a little shaky to diagnose because if the line had pressure/fuel from the previous run it will start and run a short time and then die from lack of fuel. Unless the fuel pump activates when the key is turned to run, prior to full start, then there will be no fuel coming from the pump. No start. If you work the key to run a few times until the pump engages its good to go. The truck has never died while driving, once it gets that initial pump activation it runs good until the next start up cycle. When the pump does work it builds up to good "book" pressure and holds it at 39 when the engine is shut off.
We have put off changing the fuel pump for obvious reasons but can not see how it could be the problem since it has never quit once after we get it started. Are we wrong? We know the fuel shut off is on as it will run. We have changed the key lock tumblers, the ignition switch and the fuel pump relay. (behind the radio). Next up is to re-seat all the fuses and relays in the main fuse panel box under the hood. I just read that today on FTE. Is there a test we can do or some engine codes we need to look for? This problem is getting old fast.

I have a super duty with the 5.4 in it. it just quit while off road n wouldn't start back up. pulled it back to camp, wiggled wires around cam n crank sensors n it fired up n stalled numerous times then just wouldn't even fire back up. loaded on trailer n brought home, buddy put his tester on there n said there was no rpm reading so I replaced the crank sensor, it fired up n stalls still. wires seem to be good to crank n cam sensors. don't have a manual to tell me what relays are what.

I recently caught up on some maintenance with my truck, changed the turbo pedestal seals, replaced both batteries, brakes, e-brake cable etc and installed new 10k hid headlights. its a single cab 250 with a 7.3 and zf6 4x4 with 133k. a couple days ago I turned on the headlights and the truck died, restarted no problem and would die the next 5 times I tried to turn them on, then it worked fine. yesterday I got in my truck to leave for work and got no wait to start light, no glow plug chatter, no fuel pump running. turns over just fine but no fire.
I got a ride to work and tried it when I got home, fired right up. I pulled the pCM, checked it out, no weird smells and my TS chip wasn't corroded or anything like that, worked fine. drove to 711 to get a 6 pack and it did the headlight thing again. I removed the HIDs because this all started after I installed them and reinstalled my silvanias and it didn't die when I turned them on. this morning went to leave for work, same no start condition. I disconnected both batteries for 30 seconds to reset anything and same problem. I was about ready to light it on fire this morning.

I have a 2000 f250, 5.4l triton v8 that cranks like crazy, but won't start. When I spray a little starter fluid in it it will run until the spray wears off. Brand new battery and full gas tank. it does have check engine light on dash, probably from the o2 sensor as the exhaust has almost completely rusted out. Also on a side note the cruise control will not engage.
