Ford F-150 (2004-2008) :: No Power To The Starter Solenoid
Yesterday after work, i got in my truck and it started right up, no problem. my stereo has been giving me some fits the past few days, looks like everything is on but no sound, and was thinking it might be a fuse so i proceeded to shut off my truck and take a quick look at the fuse box. didn't find anything quickly fuse wise, so i got back in the truck to go home and turned the key and nothing. no whine from the starter, no click click click like a dead battery, but i do here a single click from the relay switch as i left the case off to do a more thorough investigation on the stereo when i got home. anyway.. here is all i have ran through.
1. Made sure the battery is good, even tried jumping it for good measure..took cables off and made sure they had clean connections.
2. Switched out the relay, and fuses related to the starter in fuse box.
3. Put the truck in Neutral, thinking safety switch.. wiggled it around while trying to start it as well
4. Crawled under the truck, took a screw driver and bypassed the switch all together to make sure it wasn't the starter, starter kicked in like it was new, but no truck start. (key was in the on position)
5. Checked the solenoid post with a test light to see if it had power on key turn, nothing.
6. Checked the fuse box and surrounding wires to make sure i didn't bump anything when taking off the cover..
From all of this it sounds like some safety switch that isn't giving power, otherwise i would have thought the truck would have started when i bypassed the switch on the solenoid. Just seems very odd the timing of it and i have not had any previous issues like this.. just out of the blue, literally less than 5 minutes from starting the truck without issue.

Ford F-150 (2004-2008) :: Cylinder 2 Misfire And Lean Fuel Bank 1
I am getting cylinder 2 misfire and lean fuel bank 1. change the coil and didnt fix the misfire.
View 2 RepliesFord F-150 (2004-2008) :: Lean Condition Bank 1 And 2 / Random Misfire
2006 f-150 with a 4.6L. Its got 175k on the clock and ran like a sewing machine despite little maintenance other than oil changes. Recently it started running like crap; no power and missing so he borrowed a scanner and it was giving multiple codes. Here's what we have done so far, not necessarily in this order :
1.Checked for vac leaks with carb cleaner (this can be tough as engine runs crappy and hard to detect minor changes in rpms while your under the hood) no leaks detected yet
2. Changed the plugs, all looked good except for one which was heavily fouled and the electrode ate away mostly, I wasnt there and he doesnt remember which one but have a suspicion, more on that in a min
3. Changed most of the COPs and checked them all with a spark tester, all are firing.
4.Cleaned the MAF sensor with MAF cleaner
5. Checked back pressure on the exhaust by removing an upstream o2 sensor and holding a plastic fitting hooked to a pressure gage long enough to get a reading, about 1 lb idling to maybe 2 max when engine is reved, gage is not the best and fluctuates a 1/2 lb or so. Exhaust does not smell of rotten eggs.
6. Changed the fuel filter, it was terrible
7. Ran a bottle of Seafoam in the tank
8. Took the throttle body and egr valve off and checked for carbon stoppage, the holes in the egr were not blocked
9. checked the PVC valve and line and both elbows
7. checked the injector connectors with a noid light for signal, they all flash, checked the injectors them selves with a multimeter set for ohms, all about from 13.5-14.5. This should mean they arent fried but could they still be stopped up? They all sound like they are pumping when you listen with a mechanics stethoscope
9. Changed all 4 o2 sensors as this had never been done anyway
10. Compression check on cylinders, all within 10% of each other at about 180 lbs. When we pulled the plugs they all looked good except for # 7 which was heavily fouled ( I suspect the same on the original plugs) and again with a bad electrode, the part coming out of the porcelin. Intrestingly, this was an autolite plug, the rest were motorcraft, I hoped this was somehow just a bad plug but no change with a new MC plug
11. Changed the injector on #7
The scanner reads lean condition on banks 1 and 2 and random misfires on #4 and # 7 still. Per a troubleshooting tip online, we sprayed some carb cleaner in a small vac line coming off the manifold to induce a rich condition and the scanner showed the o2 sensors go to .900 which is what they are supposed to do per the guide. This means they are functioning correctly and a bonafide lean condition exists. I am leaning towards a vacuum leak around the plastic manifold under the aluminum one, maybe the gaskets but would like to rule out the egr valve, could it be the culprit?
I have even considered the possibility that the PCM is bad, though not likely. I have read to detect a vac leak you can hook the scanner up and spray the carb cleaner around on the manifold and lines with the scanner hooked up watching the scanner PID for the o2 sensors and when they detect the cleaner, they will hit that .800-1.0 meaning the engine sucked the cleaner in and you have found your leak. The exhaust smells rich. If it is a vac leak, you would think it should be a massive leak and not hard to detect, as crappy as the truck runs. I have searched the forums for days and exhausted about all I know to do.
Most important note: early on I suspected low fuel pressure as a possibility; with no schrader valve on the fuel rail and no easy spot to T into the system, we were scratching our heads how were gonna measure psi but the scanner reads absolute fuel rail pressure, gives about 40-43 psi. I hope the scanner is telling us what we need to know there, would prefer a mechanical gauge on the rail!

i have a 2005 f150 4x4 5.4 3 valve. it ides good but when it is in on it splutters, and also feels like dead cylinders in passenger gear. i checked the codes the other day and i had a cylinder 5 misfire. so i cleared it and today checked again and had running lean bank one and cylinder 8 misfire, then checked one more time and had cylinder 7 misfire. I am sure it is a bad coil but how do I know which one?

Truck has been taken care of, new Motorcraft plugs done 15,000 ago, never had any issues with truck until recently. Started bucking and kicking, threw CEL light, pulled codes. P0018, P0022, P0300, 305, 307 and 308. All of the misfires seem to be happening only on my left bank. I threw in a new camshaft position sensor just for the hell of it. This issue goes away and comes back intermittently. I drove it for a day and it did fine. Had power and then started it later to go home and it was misfiring, got to a stop light, cycled key and everything went back to normal. 2007 Ford F150 Lariat 5.4l Triton....116,000k....

Once winter arrived I started having problems with my truck running like crap after warm up. However, I noted that during initial start up and lasting till the engine got to its Normal Operating Temp, it would run like a BAOH! Once the engine reached Normal Temp, it would fall flat on its face if I got into it down the road. I wasn't getting any codes, so knowing about the EPU and timing; I opted to change out the O2 sensors. Bought all 4 sensors, Bosh, installed them and within a day got a P0420, P0303; known as Cat system efficiency below threshold and a #3 misfire. (side not all plugs, timing chains, COP's, Phasers, cam positioning sensors have been replaced within the past 18 months) So I decided to take the COP off of the #3 cyl and swapped it with the #5 cylinder; still getting a misfire on #3.
Didn't pull the plugs, knowing they have less than 50,000 miles on them. The problem lasted about a week, off and on with heavy acceleration. Then last Saturday I was driving around town, came to a stop light and the engine shook hard while stopped, missing for a few seconds but not sending a code. Upon acceleration I noticed a loud ticking coming from the right (passenger) bank. The truck practically fell on its face through 3,000 rpm's. No power, and still no codes. I got home, pulled out my steth and listened. I got a loud ticking on the cover at the #3 and #4 Cyl. I know ya'll acclaim ticking to the phasers but it's a totally different sound. Its not coming from the front of the cover as it did when my phasers went out. This is strictly confined to #3 and #4. Took it to FMC., for diagnostic fee and a day later they said, symptoms of lash adjusters. I told them I'd pick up my truck.
Got in it, and drove it home and that noise is loud, echoing through the right exhaust. Seems to be running very rich, still no power what so ever and now I pull up in my driveway and instantly get these codes. P0316 (misfire on startup), P0420 Cat efficiency below threshold, and p1000 (due to resetting my computer back to stock before taking it to FMC) I thought about doing the job myself, but working 120 hours a week I don't see how, and I'll need to buy the valve spring compressor and timing chain wedge (260.00 set) So I started calling around to mechanics, 10 to be exact, none of which, will even look at the truck.
Ford F-150 (2004-2008) :: Missing On And Off - Check Engine Light - Bank 1 / 2 Too Lean
I bought 04 Lariat (5.4 3v around 100k miles, Roush Off Road side exit exhaust, DWV intake mod, SCT 3015 tuner).
The truck has had a miss on and off for around a month I've changed plugs and tested all the coils. Which cured the problem for around a week, the FPDM had some white stuff on back and soft spot but not ate through. The only Check Engine Lights have been bank 1 to lean (which went away as soon as it came. But yesterday and today I've got bank 2 to lean.
Below is a quick data log pull... The misses is about ready to ship her out if she don't straighten up..
Ford F-150 (2004-2008) :: Rough Idle / P0012 - Misfire Codes Associated With Bank 1 And Cylinder 3
5.4 3v. my last few weeks have not made me a fan. Here are the details:
I bought a 2008 F150 XL 5.4 3v with a cam phaser knock. Have done other timing jobs in past with no trouble so I was not too afraid to tackle this one. famous last words...opened the motor (shout out to the passenger side valve cover and its designer here) and found semi damaged roller follower on driver side. Worn cam lobe on the corresponding lobe and a loose chain on passenger side. proceeded to :
Change all timing components: phasers, chains, tensioners crank sprocket, all applicable bolts and BOTH cams as well as all lash adjusters and roller followers. most looked fine in fact all really did with a bit of wear on a few roller followers but only one bad one. engine didn't look to bad pretty clean.
Double and triple checked my timing chains and it was spot on. dark link on spot on crank, two dark links on the L and R dead on. put it back together. oh yes, changed all plugs with motorcraft ones, didn't even break one. did not change vct solenoids because I falsely assumed I could change the later easily if needed. they looked ok. screens intact etc... silly me for not realizing how kind Ford was in 2007 and later to necessitate removal of valve cover. I was reading a previous one on the how tos and assumed later models would be the same since it was the same sensor...
Cranked truck ran great. I mean perfect. sounded perfect. ran like a scalded cat. till it got to hot idle then it started doing its thing. rattle shake till you revved it. ran fine just wouldn't hot idle fine especially in reverse or under slight load. replaced driver side vct since ford only had one and I started on the easy side ordered the other one waiting for it. seemed to improve dramatically meanwhile I am driving this truck to test it. I drove it to work 50 miles each way and it ran great.
After a few trips it popped the P0420 light, seemed to run ok, cleared it watched it wouldn't come back. O2 sensor did seem to imply a bad cat on bank 1 since it seemed sensor two was mimicking sensor one and not staying stead like the other bank. still ran fine,
So I decided to check back pressure on the cat. I pulled sensor one out of bank one (really a joyously tight squeeze in there) hooked up my gauge and got 0 back pressure. revved it and all nothing. hooked sensor back up pulled truck out of shop and it commenced to running like crap. I mean bad. running worse than before I got it. Popping P0012 code continuously, and tons of misfire codes associated with bank 1 ..cyl 3 etc.. I tried swapping coils, pulled coils and checked spark with a tester and firing away looks like tons of good spark.
Now the weird part is : looks like bank one is dead. I can unhook any coil pack and/or injector and it runs the same and sounds like it is missing. if I unhook one off of bank 2 it almost dies or does. so bank 2 seems to be running fine. it will start and run but sounds like it missing sets flashing check engine light and backfires and stalls like crazy. I even second guessed my pressure gauge and unhooked exhaust manifold from pipe and it sounds even prettier when it backfires out of there but no change. I pulled cam sensors and cleaned it again and even tried swapping them since they looked identical but no change so I put them back.
Now I can only surmise that I am out of time somehow? or I have a gremlin perhaps? I like working on cars (usually) but this one is getting old. how do I verify what is wrong. if it is timing related how do I verify that now definitively once my marks moved I really cant figure out how to tell if it is in time? Since it has all new parts and they all ran beautifully till now. could it possibly be the vct solenoid doing all this? I plan on changing it when it comes in but surely it cant cause this many problems.. I unhooked it no change, and it does it at a cold idle and any rpm. really runs worse at idle but bad at any rpm.
Ford F-150 (2004-2008) :: Check Engine Light Code Says Catalyst Deficiency Bank 2
I have a 2006 F-150 with the 5.4L. I got the check engine light and the computer says catalyst deficiency bank 2. So I assume the passenger side converter is blocked. Is there anyway to either take out the cat and replace with a piece of straight pipe and bypass the o2 sensors or take the cat out of the housing and put the housing in and then bypass the o2 sensors.
