Ford Fuel System :: 2001 Excursion Started Missing / Loss Of Power
Jun 17, 2013
2001 Excursion 7.3 started missing the other night. Great loss of power, but made it home. Rough idle, "clacky". Next morning, did the following in order: 1) Pulled the fuel filter inspected, 2) removed all fuel from the bowl 3) replaced bowl fuel with Seafoam 4) installed new filter (my typical procedure). Without starting, I then 5) removed HPOP oil from reservoir and 6) filled with fresh oil using exact amount removed as a gauge for what to replace.
Started, idle smooth for a time. Increased rpm by depressing accelerator. Began running rougher and rougher accompanied by white smoke. Finally quit and would not restart. Cranking easily, tachometer showing RPM during crank. Suspected no fuel getting to fuel bowl. 7) Drained fuel bowl using valve on back of bowl. 8) Turned ignition to "on" to get fuel pump to run 9) removed new filter, no fuel in bowl 10) With fuel filter out of the bowl, removed fuel filter and quickly cycled the ignition to "on" and back off -- no fuel entered the bowl. 11) Removed leads from fuel pump. 12) Checked voltage across leads as ignition cycled to "on": 6.5 volts. 13) Checked fuel pump fuse (20A Maxi fuse in location 112 -- BLOWN!) 14) Replaced fuse, performed voltage test: 11.55 volts 15) Checked battery voltage: 12.44Volts.
So, with all that, how in the world does the fuel pump get 6.5 volts with the fuse blown? I looked closely at the fuse and there was no slag or connection in the element. Today I have pulled the 9-pin and 42-pin connections on the valve covers as well as the connectors to the glow plug relay module (used on Ex's) to inspect wires and connections. All looked fine. I plan to us some LP5 electro contact cleaner to clean all the connections and put some electrical grease on the connections, but the big question is where did that 6.5V come from with the fuse blown. I plan to pull the fuse and do the same test to see if the 6.5V is still there.

My father owns a 2003 Santa Fe GLS with the 2WD 2.7L V6 engine.
Recently it has been having lots of power loss issues. It vibrates/misses when idling, if you put your foot down on the gas pedal, whether under load or not, it sometimes stalls or just sits there. We took it to Hyundai, and they had no error codes. They charged us $150 to tell us nothing is wrong with it, when clearly something is. The car has become downright dangerous to drive because it cannot make it up hills without stalling/losing power.
The most recent thing we had done to it was the wires/spark plugs changed, which I think was at 65k on the odometer?

So my 1987 Econoline Van was running fine until recently we noticed loss of power going up the slightest of hills and it will only hit 55 max with gas to the floor. Its shooting out black smoke and also dying when we stop. We are getting very poor fuel economy as well.
We got a tuneup, oil change, new air filter, etc. We also had a few electrical issues due to a short we thought we had fixed completely... So I'm wondering if it could be the timing? Cause it'll idle low, then high, then bog down and lose power...
Also was thinking maybe bad fuel pressure regulator or fuel pump....but how would I check this? And since we did experience a short, could we have blown a sensor too?

I purchased an '03 V10 Excursion back in '13 with about 145000 miles on it. I've added another 30,000 in the last year and a half. It's been good but has started missing and has gotten to the point where it will shut off at times and I don't know how to troubleshoot it. The MIL has never lit from the missing. Twice after it cut off the MIL was lit with a speed sensor error.
I've purchased a BAFX Products Bluetooth OBD2 interface and I've tried a couple of different Android apps with it, right now I'm using Torque Pro. It says it's an OBD I system which I saw references to in the "Why your MIL doesn't turn on" thread. I'm seen references to using Mode 6, but everything I've read seems to indicate that's an OBD II feature.
The missing gets better and worse. Some days it will seem to be fine and then other days I have to keep it rev'ed up to keep it from dying while stopping for a red light.
When it dies, it dies while stopped in drive or reverse. It has also died a couple of times while moving in reverse while connected to a 3,500lb trailer. Every time it's died it has started right back up.

I have a 1988 Ford F-250 Lariat, 7.5L 460, four-wheel drive. I have two fuel tanks on it, and I've been having a really annoying, obnoxious problem with it lately. After running it for a while, I noticed that I keep losing fuel pressure, and the truck stalls. When I try to start it, it does nothing but roll over. It just won't start. I've changed the fuel filter, I know both fuel pumps are working (I turn over the key, I can hear front, back, and high pressure pump attached to the left side frame rail kick in.) It's Fuel Injected, not EFI, hence that third pump. The problem happens a lot, and it's random. I could drive for 100 miles, stop to get something to eat, come out, and it won't start.
I thought maybe it was the fuel pressure regulator, but I don't think that's the case because it still runs. I would assume that if the regulator was bad, it wouldn't run at all. I also thought that maybe it was the relay, but according to some mechanics I spoke too, if I can hear the pumps kick in when I turn the key over, then the relay is fine. The only thing I could think of is that it might be the fuel selector switch. Maybe it's going bad, shorting out or something. When I flip the switch though, it switches between fuel tanks, and the gauge reads how much fuel is in it from the sending unit.
There's a schrader-type valve up by the fuel injectors. When I push it in, it barely squirts any fuel out, if at all, so I know the pressure is low. When I push it in on a good day, it sprays out like a water fountain. Just tried starting it again - no good. Pushed on the valve, it spurted out some fuel pretty well, but still won't start. Occasionally tries to, but ultimately won't. I know the spark is good, checked the plugs/distributor cap. Can't get the sucker to start.

I got a new ipr an looking in the oil pump end there's a small spring with a screw n the middle. Is this a pressure adjustment for the valve or what any body no. I have a 97 power stroke that when i start it cold idles fine as engine warms it starts to miss . I have changed everything i mean everything but ipr and map sensor.

The other day I was driving down the road on a long, flat section and all of a sudden my truck started missing out of the blue. Ever since it started missing it hasn't stopped. The truck is an '89 Ranger, 2.3l, 5 spd. The plugs and wires were replaced last year along with the timing belt and fuel pump. It has been running great since then until now. I thought maybe it might be a clogged fuel filter so I replaced that but it didn't work. Also, it doesn't miss all the time. It doesn't miss when its idling or if you are going down the road while it is missing and slowly release the gas pedal it reaches a point while you are letting the pedal up where it will even out. It definitely seems like it is an "under load missing" scenario. Also, the Check Engine Light is not on. Where should I start looking?

I was driving down the road and the car was driving great. all of the sudden I heard a clunk and the car lost power and started shuddering. I made it home and cut the car off. When I start it now, the car runs rough and stalls out. I can't get it to a place to check the codes so I am trying to self diagnose. I was thinking it might be the MAF so I took it out and cleaned it well. there is still no change in the way the car runs. it seems like the fuel isn't getting to the engine as I put my foot on the gas pedal it stalls out. I'm not too excited about buying a throttle body if it's the MAF. It could possibly be something else.

I was looking around under the hood and I'm pretty sure I'm missing a bolt and maybe a nut too. The bolt hold the fuel line I think. Is there supposed to be a nut holding the fan shroud on here?
I know I could go to the hardware store and eventually find something that works, but that is a headache and they don't like me test fitting until I find the right size. What is part number?

My truck will be running real good then all at once start missing so bad it shakes gear shifter,spits and pops and then goes back to running fine.

I have a 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.

My 02 excursion is missing at idle and jars the whole truck around going approx 50mph feels like good amount of power loss but still pushing 30psi boost, just got autoenginuity all injectors buzz fine on the test, contribution test show balance fault in cylinders 1&8, should I look for o-rings to be bad, uvch, cups cracked or what ----- turbo fine, hpop great condition, new IPR, new fuel pump and hutch mod, about. 250k miles on truck nothing else major showed up on ae.

We have a 2002 Sante Fe with v6 and 270,000 km on it. Just had extreme loss of power and jerky acceleration from a stop. This has happened a few times in the past year and each time with a 1/4 tank of fuel? We pulled into a gas station, filled it up and away we go like nothing was wrong?

I have a 2001 Ford Windstar SE. 220,000 miles. A few months back it started missing ... I drove it like that just local for a few days but then I was leaving town for about a month and just parked it. After I got back I changed the plugs and all was fine on the test drive (ran perfect ... fixed the misfire). What has happened since then has been frustrating. Althought it runs great, now it stalls randomly and always when it's under acceleration and usually going up slight or a bit steeper hills (think So Cal terrain). It doesn't jerk or miss or sputter ... it just cuts out.
If you try to turn the engine over without turning the key off it won't start. Turn off the key then turn it on and it starts like nothing ever happened. No codes whatsoever. Sometimes you can drive it for 30 to 50 miles or more and have no problems at all, then all of a sudden it will stall in an area that it had no problems with over the previous week or so. It seems to stall out at about the time it wants to shift from 1st to 2nd or from 2nd to 3rd ... or at least that general rpm or accelerator pedal position. It's happened with light acceleration and heavy (pulling a long hill) acceleration. Never at idle or decelerating or just cruising on a flat piece of roadway ... never. It also seems the pedal needs to be at a constant position (not pushing down or letting up but just at a certain position under acceleration). I've had my mechanic with me 3 different times and each time it never stalled with him along. Fuel pressure was fine when he checked it (while driving).
Once in a while it will cut out (just enough to notice) then cut right back in and keep running but most of the time it just cuts out and that's it. I've changed the camshaft sensor, the crankshaft sensor, the PCM relay, the fuel pump relay, the throttle position sensor and the fuel filter. I'm hoping to set it up next week where if it stalls I can call the mechanic and have him come over to where I am and see if a code comes up (and check the fuel pressure also) without me turning it off (since that seems to reset whatever the problems is).

2002 ranger edge 3.0 5spd. Truck idles perfect, but when you get rolling and higer rpms feels like the engine is missing. loos of power and shakes. I replaced the usual, plugs and wire's, seemed to work for a bit but came back. I cannot get any info on the scanner and have checked all the fuses. I am thinking coil pack but don't understand why it idles perfect and only misses under acceleration. No check engine light on.

I've got a 01 f150 yesterday stopped running (like it ran out of gas). Has half a tank. Fuel pressure at rails good but truck will not turn over. Fuel pump and filter less than year old.

My truck is a 2003 f250 / 2wd automatic, 7.3 powerstroke, 284000 well maintained miles.
Just last week I sprug a large oil leak and had to replace the hoop outlet o rings..problem solved. This week I can drive 15-20 miles on the freeway and the truck starts to act like ota running out of fuel. Bogs down to 40mph then starts missing. I pull over, and when revving I have un burnt fuel and oil smoking out of my tailpipe. I let it sit for 5-10 minutes and it will be fine for the rest of the drive and this happens intermittently, there is no pattern.
The truck has a ton of power, starts great hot or cold. I did a ton of research and found a IPR could possibly cause this, as could plugged screens in the fuel pickup. Then I read about all the injector harness issues but I don't think that I my issue.

While driving home the other night at highway speed my truck lost power. I just filled the tank about 15 miles before then and everything was running fine. No lights came on the dash before the truck died and now can't get it started. Bad fuel? Clogged filter?

1987 f150 302 4spd 4x4. When I bought the truck 4 years and 12K miles ago the orig owner had just installed a new front pump (in tank) and new switch thing on the frame rail. He said shortly after that the rear pump stopped working so he just ran off of the front tank. That's what I've been doing also except as of the last few months it has started to leak from the rear tank (I don't ever put gas in it and was empty when I bought it) and dies periodically from time to time? Where the leak could be coming from. I do suspect the dying has to do with the leak though.

So I have been fighting a rough running, missing problem. My truck started running rough one day on the way home. I got it scanned, it showed injector contribution balance 1&2. Made sense to me that it threw those codes. I replaced 1 and 2 with oem replacements. Got that all done, truck still ran like crap. I changed fuel filter with motorcraft ones and drained the water separator. That didn't work. I am getting it scanned again, so i will have codes shortly.
Also, for a while it would run with absolute no problem. It was intermittent like that. Run bad run bad run bad and then one day run flawlessly. I though it was electrical. Checked all the common places for chaffing, saw nothing. Even did the wiggle test while it was running, no change. But it hasn't been intermittent for a while now.

A few weeks ago I replaced my CPS on the 99 7.3. Today was the first day I drove my truck in the rain. When I turned my wipers on, I noticed that I lost power and my truck started hiccuping. I read on these forums that an aftermarket CPS is most likely the problem, so I am planning on getting a ford CPS this afternoon. My biggest concern is that before I replaced my CPS, my wipers only had 2 speeds. Also, if I pressed the end of the blinker switch to squirt the cleaner the wipers would not turn off until I turned the truck off. I am not sure why this would be happening and I wanted to ask if there is more than just the CPS involved with this.
