Ford F-150 - 1997-2003 :: 1999 Triton Turns Over But Won't Start
1999 F-150 XLT 5.4L Triton 4x4 super cab with a 4" body lift. I bought it used. It has 225,000 miles with engine and transmission rebuilt. This truck doesn't get driven every day - sometimes sits for a week or so at a time...
Issue: A couple weeks ago, it took 4 or 5 attempts to get it to start. Once it started it ran fine and re-started fine. Then my wife drove it but parked it back at home with the gas practically empty. Then it sat for at least a week or so before attempting to start it again. Now it just turns over and won't fire. I suspect fuel pump relay, fuel filter, or fuel pump (hoping its not the latter)
What I have done so far:
1. I put more gas in it in case it really was skimming the bottom of the tank.
2. I tried cycling the key several times thinking that maybe the fuel line just needed to prime.
3. I don't hear the fuel pump "whine" for two seconds when I turn the key to just before start.
4. I checked the fuel pump relay fuse (#10) - not blown
5. I have swapped thet fuel pump relay (#301) with another relay
6. I put 12 volts across the just the relay and I can hear it picking up and dropping out (when not inserted into slot 301)
7. I put my hand on the relay and had someone else turn the key and I can feel it picking up and dropping out (when installed into slot 301)
8. I went and checked out a fuel pressure tester from auto zone and connected it to the schrader valve and got 0 psi while turning the engine over.
All this points me to the fuel pump, but I am not looking forward to dropping the gas tank. With 0 psi, I doubt the filter is just clogged. I would still get some kind of pressure at the fuel rail, right?

I have a 99 5.4L V8 Triton engine. The power steering is not working. Need a full power steering diagram including components and hoses/lines? I have attached a picture of a broken line which I think might be for the power steering but I'm not sure. What this (?) line is in the attached picture or have a diagram?

New truck to me. Truck was advertised with a slow coolant leak. Figured I would trace the leak down and get it repaired no issues. Anyway, working on it this evening I take a close look around the oil filler area and notice the dreaded milkshake color.
I drained the oil out of the truck and the oil actually came out nice and black. Is the headgasket the only area that would cause the oil/coolant mixture? Supposedly the truck has never been overheated.
At any rate, on to find articles on how to pull apart a 4.6L Triton head. I'll see if I'm up to this challenge.

I just bought a 2007 f150 4x4 5.4 triton with 69 thousand miles less than a month ago. Since then the transmission has been rebuild but come to find out a misfire will cause overdrive to act up, and it just recently started misfiring badly. It was throwing a code. 2 coils were replaced and still misfiring. It's not throwing a code anymore. No check engine light flashing or nothing.

I have a 1993 Buick Park Ave Ultra with 127,000 mi and it has a rattle like noise in the engine. I took it to the mechanic and he said it was the supercharger and that if that went out the car would not run. I would like info on the supercharger, eg. is it critical for just riding around town and exactly what it does, and how expense is it to fix/replace.

View 1 RepliesMitsubishi - Triton :: 1998 - Coolant Won't Suck Back Into Radiator When Cools Down?
I have a 98 mitsubishi triton v6 3.0, I am confused with a issue I am having, coolant heats up and is put into reservoir tank as normal, but when car cools down it does not suck it back into radiator.
Have purchased new radiator cap.
No coolant on ground or any visible leaks in engine bay.
No white smoke when starting car or running
No sweet smell of coolant burning
No leaks inside heater
Car doesn't overheat, just pushes more coolant Into reservoir
Slight bubbles in radiator when cap off
No coolant in oil
Put a bottle of radiator leak fix in, no improvement,
Only thing is that 3 out of 5 intake manifold bolts are stuffed, they grab but don't get a tight fit, could this cause the vacuum leak not returning the coolant to radiator....
Ford F-150 - 1997-2003 :: 1997 - Click Sound From Converter After Reinstall Engine?
I have just finished changing head gasket. I started up the engine works fine. But I hear a little clik sound form the converter. I put it in gear, but it can't move either forward or backward. It ran 2-3 liters of oil out of the converter when I took the engine out. I have filled new oil in the gearbox but not in the converter, dosnt it came form the gearbox into the converter?Is there air in the converter or what's wrong?
it is a F150 4x4 4.6 1997 automatic.
Ford F-150 - 1997-2003 :: 2003 - Got Code U1262 - Random Misfire?
I have a 03 F150 with a bi-fuel 5.4 engine an it has 195000 miles. I have had trouble for some time now with misfires. I bought the truck in october of 2011 with 125000 miles and replaced all the coils and spark plugs because it was misfiring badly will running on CNG. It was fine on gasoline and never had any codes. After I replaced the plugs and coils it ran fine on CNG and gasoline.
This summer 2013 it began missing badly at highway speeds only when running on CNG. If I accelerated the miss would go away until I was light on the throttle again.I checked the misfire count and found the bad cylinder and replaced a coil. Then a day later same thing on another cylinder. I swapped a coil from another cylinder and problem went away for a day. Eventually I chased the misfire around all the cylinders on the engine until I had ended up either replacing a spark plug or swapping a coil on all the cylinders. And I still had a misfire. It seemed to be worse on days with temperatures above 90 degrees. Eventually I got it to stop misfiring.
So now 5 months later I am back again with a misfire. This time it is misfiring on both gasoline and CNG and under any throttle conditions, except coasting. I have no codes. And the misfire monitor is sending me around the engine again. I have replaced a spark plug in two cylinders and swapped 4 coils.
I'm ready to buy all new coils, but I want to be sure that it is not a waste of money since the old ones only have 70000 miles on them.
Two days ago I had the misfire monitor saying #4 in the evening and the next day without me having done any work on it it was saying #6. Later that same day it said #7 and I still hadn't done anything other than drive the truck.
I checked the connections at the firewall on the drivers side with the three large plugs that are held in with a 10mm bolt, they looked fine, no corrosion or burnt pins. I checked the connection at the ACFM which also looks good. I will check the connection at the PCM in the next day or so.
Some other problems that may be contributing:
1. I occasionally get a U1262 code (scp fault)
2. Sometimes when I check the misfire monitor it only shows 7 cylinders, sometime 9 cylinders. I am using an Innova 3160 scanner.
3. I have either a leaking valve cover gasket or leaking head gasket, because I have oil dripping from the rear bottom corner of the passenger side cylinder head right above the exhaust pipe.

Ford F-150 - 1997-2003 :: 2003 F150 Cranks But Won't Start
This has happened twice in 3 years....I get regular service from a Ford dealer and am overdue.... I think it may be temp related. Has been below freezing the last few nights. Truck was parked on an incline during the last two "shutdowns" ( engine lower than bed slightly), I drifted to a level position and it started. This has only happened twice previously. Now it seems to be a permanent problem but I am unable to get to the dealer without a tow... which I am trying to avoid.

I have a 03 4x4 5.4lt supcab with 154k miles. I replaced the shift motor about 40,000 ago but it has always been tempormental like I had to engage it in 4lo in N and then shift to 4hi to keep it in 4hi. Now fast forward to today. Went to shift to 4lo in N and it didn't shift. I only heard the relays click once and then it wouldn't shift into any gear even though the indicator was on PRND123. Didn't matter.
Also, Park didn't engage and the speedometer acted like it was engaged in RN and D. No movement what so ever. I think it might be the shift motor that shifted part way and is stuck in between gears. Is this possible? I drove fine to the dirt road and I haven't had problems other then the shift motor being touchy. I don't want to pay for a new tranny if it might be the shift motor.

View 8 RepliesFord F-150 - 1997-2003 :: A/C Won't Take Charge?
I have an 03 F150 that I put a 4bt 3.9 cummins diesel in a couple years back. I'm just now working on ac issues. I have custom lines built and have a new drier in it. I am uncertain of the location of the expansion valve. I have not found a diagram of where that would be. It is a supercrew so it has the large condenser and I don't remember seeing the expansion valve/filter in that line when it was apart.
So I pulled full vacuum on the system and let it set for over an hour and it held the full vacuum. I plugged the Freon to it and it pulled just a small amount into the system. with the vehicle off it registered about 90lbs on both high and low with just the one can attached. I closed high side and jumped the ac pressure switch and it dropped to about 30 lbs on low side, but would move back up to 90lbs when I turned compressor off. It would not pull anymore out of the can. Do I have a plugged filter somewhere?
Ford F-150 - 1997-2003 :: Oil In Radiator?
Just like the title says oil In my rad! Anyway here's what I've seen....I noticed that I've been having to put oil in my truck more often than I need to. I thought maybe I was leaking somewhere but I wasn't. So then I thought I was burning it but no smoke. So then I was reading on this forum and someone mentioned oil in the rad. So I checked and it was pretty black in color so I figure that's what the problem is. My question is would it be a head gasket or intake? I also read a quote from Moto Mel on here that it could be some kind of adapter that is located on the lower left side of the motor that has o rings that can go bad and cause this?The milage on my truck is 145000 and running great (other than this). No overheating or anything.
