Ford F-150 - 1997-2003 :: 2001 - Oil Pressure Gauge Dropping To Zero Intermittently?
Just recently got a sweet deal on an 01 Lariat with a very low mileage 5.4L. I almost didn't purchase it because the oil pressure gauge will not read when you start the engine. Sometimes it will sometimes not.
When it does read, it is just past half which is the normal reading. When it doesn't read, it shows zero and the light is on. The engine runs fine either way, and the previous owner said it has been that way for years. The engine has been well cared for, and has been running Mobile 1 full synthetic for most of the 80k miles. The oil was not overly dirty at purchase, so I figured it to be a loose connection. I suffer from the cold solder joints that these trucks are plaqued with, as evident by the intermittent odometer reading. Do you think the oil gauge issue is the same thing? A cold solder joint? Or should i just start with a new sender?
Ford F-150 - 1997-2003 :: 2002 - Oil Pressure Light On / Gauge Went To Zero?
2002 F150, 4.6 V8, 140k miles. Oil level good, oil was changed 2 months ago.
Driving along one day, out of the blue oil pressure light comes on, oil pressure gauge went to zero.
Engine did not run hot, no bad engines noises that I can hear.
Upon restart, oil pressure will be up on the gauge for minute or so, then goes to zero and oil light comes on.
Asked around, some say oil pump, some say oil filter or pickup tube.
Ford F-150 - 1997-2003 :: Oil Pressure Gauge Jumps Around / Sometimes Shows No Pressure
'97 F150 4.6L 4wd automatic... My gauge jumps around, sometimes it works and other times it shows no pressure. Could that be the oil pump? Or is the gauge most likely bad? Whats the actual purpose of an oil sending unit?

I changed the sending unit and replace the oil filter with a motorcraft unit and still can't get the oil gauge to read pressure. Since it is a gear oil pump I don't believe it is the pump.

I have an 01 F150 Lariat Supercrew 4x4 with the 5.4 Triton. The truck has 222,000 miles on it. Recently, I have noticed that when I am stopped at a stop light/stop sign while in gear, the oil pressure gauge drops to zero and the light comes on. As soon as I let off the brake and give it gas, it pops back up to normal. While driving, the needle never moves and stays consistent until I stop again, and back down to zero it goes.
If I put the truck in Park, the pressure goes back to normal. Same with neutral. It seems it is hit or miss and does not do this all the time, but I just wanted to see what your thoughts are. After doing some research I am leaning towards an oil pressure sensor/sending unit.... The truck runs perfectly fine, I just want to make sure it is not something more serious.
Ford F-150 - 1997-2003 :: Oil Pressure Gauge Doesn't Move From Lowest Point
My launch scanner reported a bad oil pressure switch, but I've replaced that, and when I did the oil pressure light went away, but my gauge still didn't work. Could it be a faulty switch? Or is it common for gauges to stop working on these fords seeing how there's a resistor to trick the gauge from the factory anyway? If I smack my dash the gauge will raise and lower. But I think that's normal.

I am looking at a 1997 F150 with a 5.4 in it, guy who owns it says if you drive it down the street the temp gauge climbs and then the truck goes into limp mode but if you check the engine temp under hood it is nowhere near overheating. Where I should start to look for a problem here? If this is too complicated I will pass on the truck, its not worth it to me to get this truck if it is going to be a nightmare. I have a 2000 with a 4.6 that runs great so this would just be a spare for me, but would like to have it because its in such nice shape.

I am installing a fuel pressure gauge into my 02 7.3 I went to the thread the sensor into the plug hole on the fuel filter housing and it wasn't threaded, turns out the sensor thread is slightly smaller and a different thread ... The directions say to install it into the filter housing or the lift pump ... So I'm assuming I have to go the lift pump direction of installing it but where the lift pump is or how to install the sensor into it while not throwing a code or causin problems ... A step by step and even pictures.

2001 F350 with 5.4 ... No leaking brake lines. The bad calipers have been replaced. Brake system doesnt seem to build pressure when the truck is running. The pedal gets stiff when the truck is shut off but when its started the pedal goes to the floor. Just put in a new booster and master cylinder. Flushed and blead all the lines several times now and got all the air out and am now getting a nice solid stream of fluid.

My 2002 F150 Screw has been giving me issues when trying to start it for the last month. Sometimes it will start sometimes it won't. When I turn the ignition on the gauges all seem normal, the theft light turns solid then goes out, but engine will turn over but not start. Sometimes it will start if I leave the ignition on for 20 seconds then pull the key and try again. (this doesn't always work). I have disconnected the battery for about 2 minutes this usually works but not always.
Sometimes it will start first time with no issues. Once the the engine fires it runs fine. Another symptom is when I shut the engine off, pull the key and open the door, the chime telling me that the key is still in the ignition sounds. (but the key is in my hand)
I put a new battery in yesterday to rule that out and because the old one seemed to be getting weak. (starting issues didn't go away). I don't want to put 300+ into a fuel pump without being sure that's the problem.
Ford F-150 - 1997-2003 :: 2002 - No Oil Pressure And Rattling At Idle
I bought a 2002 f150 4x4 with a 4.6l. It has 250k miles on it. a couple days ago. It had no problems at all during the test drive or for the 150 miles home. Yesterday after it warmed up, the oil pressure dropped to 0 while at a red light and had a rattling noise. Not a knock but more of a rattle. I can't isolate where the rattle is coming from. Oil pressure comes back with just the slightest of increase Of RPM and seems To have plenty of power while driving. I had read to check the pressure manually but with the noise I sense there truly is a problem. the oil appears clear and is full. What I should be checking on this.
View 1 RepliesFord F-150 - 1997-2003 :: Truck Will Turn Over But Won't Fire
A couple of weeks ago my truck wouldn't start. I replaced the crankshaft position sensor and when that didn't work I took it to a mechanic. At first it wouldn't start for him either. After move the truck inside he tried to crank it again and it fired right up. He said he didn't want to replace something if he wasn't sure what it was. Today it wouldn't start again. I bought some noid lights as suggested on line and tested one of the injector connectors and it did not light up. I realize that the injectors are not getting the needed "pulse". Whole thinking about what to do next I noticed that there was a broken wire. The wire is going to a really small looking box of some sort that is attached to the engine close to the injector at the front of the engine. What the wire is for and I am really not sure what to do next. I will try to upload a picture...

If I turn on my ignition switch and my gauges go to where they're supposed to be, the truck will crank. If I turn switch and , lets say gas needle for example, the needle goes to full then drops back to empty, the engine will turn over but will not crank.
View 2 RepliesFord F-150 - 1997-2003 :: Truck Won't Turn Over Intermittently?
Own a 1997 F-150, 4.6 L, 4 x 4. I know it's old but it's in very good body shape, has been undercoated for years. I've only had it for a year. This summer it began to not start (intermittently). The dash lights all come on but the starter will not engage. Brought to my local garage, he changed the starter and the ground cable from the battery.
Was ok for a few months and now it's beginning to do the same thing. Brought it back to him, can't find anything. He did say that the battery is a bit weak, the terminals are spotless (I keep them spotless, coat them with white grease). I measured the voltage with the engine stopped and with it running. Stopped, the voltage is 11.94, running it is 14.87. This clearly shows that the battery is weak.
My question is would this cause the starter to not engage after 4 or 5 turns of the key and then on the 6th try, the starter turns over? I don't want to spend more money ($ 450) the last time and have the same result. If it's possible it's the battery, I'll replace it no problem.
Grand Prix :: 2002 Pontiac Speed Dropping On Highway - Temperature Really High On Gauge
One day, I was on the highway and my Pontiac's speed started dropping. I looked at the temperature gauge, and the temperature was really high. I flushed the coolant system, and changed the gasket. Also the mechanic said that the oil might be leaking after they changed the oil. I paid like $700 for something that has nothing to do with the problem (I paid for a spark plug, ignition wires, fuel filter, and an oxygen sensor). After they changed the oil, oil started leaking all over my driveway, which didn't happen before. It also looked like coolant was leaking out. None of this happened before I got my oil changed with these guys.
After I changed the gasket, the car was running smoothly. But today, the same thing happened again, and I don't know if it's the thermostat, or water pump, or oil leaking, or coolant. The mechanic always suggests to fix something that doesn't have to do with the problem. I don't have much money on hand, so I need to only fix what has to do with the temperature rising, and I need my car to run.

My aunt recently gave me her 02 f150 for free because it got flooded and she didnt want to fool with it. she said it ran great before it got flooded. I flushed everything. oil, gas, and tranny. I blew water out the cylinders and replaced the spark plugs. I took the fuel injectors out and cleaned and cycled some b12 threw them. The truck starts and gets spark to every cylinder and is only running on 3. I can pull 3 plug wires off and the idle does not change. Idk what it could be but dead cylinders. I am afraid I am going to have to find a new engine. I am going to do a compression check later this week when I have time. I am new to fords so if there is anything I should check...
