Ford 7.3L Power Stroke (1999-2003) :: Electrical Power Fluctuations EGT Gauge Failure

I am on my third EGT gauge. My mechanic installed it as per "auto meter" specifications. He told me, the only reason he could find that the gauges have been failing is low voltage output. I have an onboard compressor for my airbag suspension and every time I start my vehicle it runs to fill up the air system. The voltage drops to 11.1V. It comes up once all is running and the compressor quits. is there any such thing as surge/brownout protection for these systems?

Ford 7.3L Power Stroke (1999-2003) :: What Gauge Wires The Battery Cables

What gauge wires the battery cables are on these trucks? Son in law has some really corroded cables on the Excursion. I was going to pick up some welding cable and replace them, but a quick glance looks like different sizes for different cables.

Looking for a list of gauge and length for each one to save me a little time?

Ford 7.3L Power Stroke (1999-2003) :: Fuel Gauge Goes To Beyond Full And Stays There

Two years ago I acquired a very very nice 2001 F350 DRW crew cab. The person I purchased it from put a Remanufactured 7.3 in it and set the truck up to pull wedge trailers. He put 25K miles on it and put it on Craig's list where I found it. It just turned over 300,000 miles.

One of the changes he made was to install a 70 gallon fuel tank in the frame rails below the bed. He told me that when the gauge reads EMPTY there is still 20 gallons in the tank. I remember him telling me that this anomaly is due to using the stock Ford pickup in the larger tank.

I have never filled the tank because so far the truck is used locally. I usually put 10 to 20 gallons in and when it gets to E I do the same fueling.

Then one day I turned the key on and the needle went up and beyond the full indication.

I can get under it and maybe the tank has some name or model number on it.

The truck runs fine, but the gauge concerns me. Eventually the truck will be making round trips from Chicago to our retirement home in Santa Fe, NM. It would be nice to have a working fuel gauge!

I have spoken to the person I purchased the truck from. He installed the tank as part of a complete upgrade that included a re-manufactured 7.3. The fuel tank is a 67 gallon Titan mounted between the frame rails. He believes that the original Ford sending unit was installed. That means it has 300,000 miles on it. I had the truck on a lift yesterday and it is a very tight fit. The garage said the best way to do the repair is to remove the bed. Six bolts, disconnect the tail lights and the 7 pin trailer connector and it is off.

So, my questions now are... Should I stay with a new Ford sending unit or are there better ones to install? Are there any other updates to the fuel delivery system that should or could be done at the time?

Ford 7.3L Power Stroke (1999-2003) :: Some Gauge Reads Towing Light

Towed 3 axle trailer loaded with a 73 VW bug, two implement bars, plows and a small boat. I would guess total weight at 7,000 max. The ambient temp 97 degrees and very humid. I have a 2000 dually.

The following are from the ScangaugeII
TFT trans temp 175 max
EOT end oil temp 205 max
SLP trans slip 0.20 max and 0.0 in high gear

From glow shift
Water temp 196

The one I am worried about is the trans slip, from a stop taking off always went high 0.15 to 0.20 and then drop quickly. Once the TC locked 0.0 down the road. Also, when I reverse with no load on dirt I have seen 0.20 on the trans slip. I have Forscan but have not logged any temps yet....

Ford 7.3L Power Stroke (1999-2003) :: Fuel Gauge Stuck On Full

Well besides the pyro breaking friday BEFORE live tuning,and the exhaust leak I gained on the way to Texas(not inpart of the pyro not working). Now the fuel gauge is stuck on full. It looks good,200+ miles and still on full. Could it be the gauge,or possibly just the sending unit? Maybe a fuse?

Ford 7.3L Power Stroke (1999-2003) :: Installation Of Fuel Pressure Gauge?

I bought an Autometer 4763 gauge that didn't come with the correct fittings to plumb the sender into one of the extra ports on the back of the bowl. I went to the Ace hardware store right across the street and they didn't have anything (not surprised) and then Napa. They couldn't find a fitting to match either. He found that the plug threads are 7/16 20 tpi and the sender is 1/8" NPT. He suggested getting a 7/16 20tpi bolt, drilling it rifle-style, and then tapping it for a 1/8" NPT. The alternative, and what I ended up doing, was to use brass fittings to tee it off one of the supply lines to the heads. I ended up going that route but wanted to know if I should have looked harder for the right fitting.

Here's a pic of what I have now. I've test fit it, and it seems to work although I will need to insulate the hard lines because they rub due to the offset.

Ford 7.3L Power Stroke (1999-2003) :: Fuel Gauge Reading Inconsistently

I've had an ongoing issue with my fuel gauge reading incorrectly, and now I'm trying to fix it! Basically, it will change all over the place while I'm driving (not erratically, but definitely moves occasionally). I recently fixed my overhead display, but the "miles to empty" display doesn't seem to be very consistent. It will read 450 miles to empty, and then the next time I look at it, it will have dropped 100 miles or something (after minimal driving).

So I'm wondering where I need to begin looking to fix this problem. I've replaced the dash cluster using Circuit Board Medics, so I'm fairly confident that's not the issue. I've read that it can be the fuel pump or the fuel tank sender, but how to check if these are actually the problem or how much time it will take. Luckily, I've never run out of fuel and been stranded, but I need to fix this or it's only a matter of time!

Ford 7.3L Power Stroke (1999-2003) :: Coolant Temperature Gauge Not Working

Basically my coolant temperature gauge either reads as the hottest it can be, or the coldest. It doesn't jump around a whole bunch, but it's always all the way to one end or the other. From what I've read there seems to be a lot of different temperature sensors, so I get a little confused with all of the abbreviations, but I'm fairly certain I checked the correct one, next to the thermostat housing.

Using a multimeter I checked the resistance of the sensor, and it was around 600 ohms about 30 minutes after it had been driven. I'm not sure if this is where it should be or not, but it was rising as the truck cooled off.

Anyway, I'm not sure if I just tested the sensor incorrectly or if there could be another issue. A friend of mine suggested that the thermostat may have gotten stuck or something, but it doesn't seem like the gauge would switch at all if that were the case. What I should check to try and fix this.

Ford 7.3L Power Stroke (1999-2003) :: Temp Gauge / No Voltage At Sending Unit

I've read some treads on the temp gauge sending unit but I'm a little foggy on where to look for my problem. I just purchased a 2000 F250 7.3, temp gauge not working. It has a new sending unit. I read some threads about the voltage at the plug but I have no voltage on either side of the plug. The way I understand it red/white wire goes to the battery. Is there a fuse between them and which one is it? and if fuse is ok is there a cronic problem that someone might know of that I can look for?

Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 - Gauge Cluster Replacement

I just bought a 00 f250 cc that originally came out of Canada so the speedo and mileage is all in kilometers. I have bought a use cluster that is in standard units to replace it with. I am just curious if all I have to do is replace the cluster or if there is other thing that need to be replace as well to make it work right.

Ford 7.3L Power Stroke (1999-2003) :: 2002 F350 - Outside Temperature Gauge Reading Wrong

I have an 02 f350 7.3 power stroke...Yesterday I noticed the outside temp was reading wrong,it was jumping from 67 to 86 to 92 back to 67..Temp was prob around 90 with high humidity and my a/c was on..So I got to where I was going and when I restarted my truck to go home the fuel gauge dropped to empty(I just fueled the day before) and fuel light came on and outside temp still wrong on the overhead digital display...Are these two things related???

Stopped the truck restarted it and fuel reads correctly again....Went out today and fuel light back on and on empty...Outside temp wrong again,a/c is on .....I disconnected the batteries when I got home to "reset the system"if there is such thing, fuel gauge working but outside temp wrong..?? Where is the outside temp sensor ?could condensation be running onto the sensor and throwing off my temp gauge? Just strange that both these things happened at the same time......I don't think its a fuse or they wouldn't work at all. I should mention all the other gauges work correctly...

Ford 7.3L Power Stroke (1999-2003) :: Erratic Fuel Gauge - Level Would Register Full When Only Half A Tank Or So

I've been having a very erratic fuel gauge issue as of about 2 months ago. My fuel level would register full, when in fact I knew it only had 1/2 a tank or so. Then 5 minutes later it would be pegged on full. Under a 1/2 tank the gauge would read any where from 1/2 to empty from 1 minute to the next. So last week I decided to drop my tank and take a look. I was thinking maybe my fuel sender was broken, maybe a loose wire in the tank, or even that my float had dropped off in to the tank.

After dropping the tank, I removed the PK-Up and sending unit and everything was intact. I placed my ohm meter on the sending unit and it checked out fine. So I took the Pk-up and rolled back up underneath the truck and plugged it back in. I had my son turn the key on and off while I moved the float to different levels in order that it would register. It registered empty, 1/4/, 1/2, 3/4 and full just fine as I moved the float to those levels. If you leave the key in the run position and move the float, it won't register or better said, the in cab gauge will not adjust with the movement.

You have to turn the key off move the float and hold it there, then have your assistant turn the key on and the gauge will show the position that you've moved and held it at. I simply removed the plastic cover from the sending unit, and sprayed it down real good with electrical contact cleaner. I didn't scrub the copper contact area at all.

I was concerned that scrubbing might remove more than I wanted to, and really mess things up. I attached an Ohm meter and checked resistance thru out the float travel. All checked out good and I reinstalled it. So now my fuel gauge is working as it should be. I did make a video while I ohmed the Sender Unit thru it's travel, but for some reason it won't load.

Ford 7.3L Power Stroke (1999-2003) :: 2000 E450 - Low Voltage On Gauge With Good Battery - No Start Condition

2000 Ford 7.3 E450 120,000 miles...

I have changed the CPS twice
I have checked the resistance of the injectors at the IDM connector with a volt meter and the harness reports back good.
The truck will run with ether for a few seconds
I have changed the fuel filter.
The fuel bowl fills quickly
I have unplugged the ICP.
The truck is showing low voltage on the gauge with a good battery. Around 10v
I have connected my 200amp car starter and I never see over 10v. I plan to check the grounds, but I am at a loss.

Everything is difficult because this is a van body so space is limited. I have also plugged in the block heater for an hour and that hasn't made any difference. Where can I get the best price on an AE scanner.
