Ford 7.3L Power Stroke (1999-2003) :: Won't Turn Over Voltage Above 12v
Nov 18, 2015
Batteries are a year old. Drove to work. Now won't turn over even with a diesel truck jumping. Voltage above 12 and slowly drops when cranking.

Ford 7.3L Power Stroke (1999-2003) :: No Power / Zero Voltage To Fuel Pump
2003 F-350 - 7.3. With the key in the on position there is zero voltage to the fuel pump. Fuel pump fuse is good. I traced the red with black tracer wire from the pump up through the firewall and to the safety inertia switch. The switch has continuity so it's OK. Then from the safety switch I traced the green with yellow tracer wire to a fuse block plug connector. Then I checked continuity from that connector out to the #40 fuel pump fuse and it's open.
So I then i checked from the fuel pump fuse to all the back connections on the back of the fuse block and there was no continuity to any of them. So I removed the back cover off the fuse block to expose any issues. I found two board mounted relays. Now, from the fuse I get continuity to one of the relay connections. So did Ford hide the fuel pump relay and make it non replaceable? Also if this is the pump relay then what circuit energizes it? I need to make sure before I replace the fuse block.
Ford 7.3L Power Stroke (1999-2003) :: Battery And GPR Voltage Dropping?
I do run a small battery maintainer during the winter months plugged into a three way with the block heater. Alright after sitting out side for approx 9-10 hrs in 22 degree weather I did these checks. Battery voltages at 12.55V and 12.6V on batteries.
Voltage coming into for was also 12.5V. When glow plugs activated I am getting 11V on the other side of the gpr. After cycling glow plugs battery voltages drop to 9.6V during cranking and as soon as she starts back to 12.5V.
Do these numbers sounds right? In my opinion isn't the drop to 9.6V during cranking a little low or is that the normal?
Ford 7.3L Power Stroke (1999-2003) :: Intermittent Electrical Voltage Readings?
My Volt gauge on the dash has started reading around 10V with the key on waiting on the GP's. Batteries read +/- 12.6V with a DVM in a static state, no key.
But, quickly as best as I could see the reading on the DS battery drop to around 10V with the key on, GP's cycling. Cranking drops down around 8Vish.
After starting the reading on the DS battery is back up to 10V. This lasts anywhere from 30 seconds to a few min. Then it jumps up to the expected 14.6V reading.
I cleaned up the battery terminals and clamps while doing my turbo,and all the connections are tight.
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?

Bit of a confusing one as of late. Doesn't happen every time I drive, maybe 50% of the time. When I start the truck up, torque pro reads voltage at 13.9-14.1 consistent. After 30 minutes it usually drops to around 13.7/13.8. Sometimes, battery light comes on, voltage doesn't drop. I can drive the truck, park it, turn it off, restart, no side effects.
I notice if I stop, turn off the truck, and restart it, torq pro will begin to read a voltage of 12.8.13.0. Sometimes it won't budge for an hour, sometimes it climbs right back up to 13.8, sometimes the battery light goes off, sometimes it stays on.
Alternator was replaced a month ago, both batteries replaced a week ago, all terminals cleaned and secured at the time of replacement. Truck behaves perfectly normal, I'm almost at the point of putting a piece of tape over the light and ignoring it, but was curious before I go that route.
Ford 7.3L Power Stroke (1999-2003) :: 2000 - No Voltage At Plug When Brake Pedal Pressed?
Installed Tekonsha P3 on my 2000 F350 I used the recommend pig tail easy hookup when I press brake pedal no voltage at plug but when I move the manual lever I get voltage. I believe the stop light switch activates it. The fuses all check out. I did have a Banks engine brake installed by their people I don't know if makes a difference

So when its cold and im talking below 55 degrees, and the truck hadn't been started that day, it will turn over 3 or 4 times before the voltmeter takes a dive down to 10 volts or so and doesn't start. The voltage will keep falling if cranking continues. I took the batteries out and had them tested. They are both above the rated cca. So im thinking it could be the starter windings?
I did replace an injector recently so all the cranking to get it going again may have ruined the starter? But when I hook up the battery charger and jump the truck it starts. And after it has been started it will continue to start easily the rest of the day.
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.
Ford 7.3L Power Stroke (1999-2003) :: Battery Light On / Voltage Meter Only Show Barely 12 Volts At Full Throttle
The brief information:
1. Stuck/non moving in traffic on the freeway for roughly 1 1/2. During that time the AC was running, but once I noticed my "battery light" on the dash turn on, I turned everything off.
2. Since then while on my way home from work the voltage meter only showed barely 12 volts at full throttle.
3. I charged my battteries, and started it up today to go into work. While going to work the voltage meter showed 14 at its high point, but shortly there after it dropped back down to 12. At which time the battery light came back on.
New battery or alternator?
Ford 7.3L Power Stroke (1999-2003) :: Click When Turn The Key But Engine Does Not Turn Over
Drove it last night around 9pm. Parked it and went to drive it again this morning around 7:30. No cold weather here or rain. Here is what I know: When I turn the key I hear a click (not a repeating click) but the engine doesn't turn over. Batteries have 12.5 volts. I put my trickle charger on them and had full charge after about 3 or 4 minutes. When I turn the key the headlights do not go dim. I put a screw driver across the solenoid on the passenger side fender and got a strong arc. When I do that, I can also hear another click that sounds like its coming from the engine. I tapped the starter a few times with a hammer, but it still wont turn over. I'm guessing bad starter.

Trying to track down an issue (annoyance) I'm having with my 02 7.3 4x4 excursion. When I get in the truck and turn the key (after waiting for glow plugs) the starter doesn't actually turn over for 1-3 seconds and sometimes up to 5. When the truck does turn over everything works perfect it's just an annoying delay.

New to the forums, not new to fords. 1999 F350 7.3L Diesel. This has been a work truck and has seen multiple devices in and out over the years. I removed the last crap for GPS tracking etc from the last owners. The truck has worked well for a long time since until...
I'm moving slowly to a different state and so the truck got parked for 2 months. went to start it and nothing. the dash comes on and all the lights come on but when you turn the key to start the power drops and nothing.
Testing so far:
replaced the fender Solenoid
tested the starter motor and solenoid -passed
replaced the ignition switch
tested continuity of the hot and ground wires to the fender and starter and everything passed
When I shorted across the fender solenoid the starter works and tries to start the truck (unsuccessfully so far)
So the wire that goes to the fender solenoid is not working and where to trace it to and what needs to be fixed. Is there a relay or fuse besides number 30 that is in the way? where does the magical wire go so i can check its continuity?
I am stuck 800 miles from where i need to be and I am stuck here. I don't have the cash to get a mechanic and my mechanic friends are stumped. I do have a Snapon modus tester, what to do with it.
FYI the batteries are new and fully charged.
Ford 7.3L Power Stroke (1999-2003) :: Clunk Up Front On Right Turn?
I noticed a clunk a while ago but could never pin point it and today its the worse it has ever been. I did some research on this and everyone is pointing towards sway bar bushings. now if that is the case why wouldn't they just replace the sway bar link? I see some do poly bushings and others regular rubber. What is the best way to go about this? and I also see you need a shop press so I'm lucky I have one.

The short story is I sent my chip to dp tuner last week while on vacation to have Jody update my programs. The ecu was out of the truck for about a week. I reinstalled everything today. Everything works fine except my radio won't turn on. Clock only comes on when headlights are on. Checked all the fuses all good except #32 which is a 5a. Manual says it's the radio start fuse. Fuse is fine not blown out, new one installed still no power on either side of the fuse. Where should I look now. 2002 super duty

I have an electrical problem and my parking lights will not turn off. I had to pull the fuse in the power distribution box (engine compartment) to get them to turn out.
Pulled the switch in the dash (lights still work) and the switch is good so it appears I'm getting power to the circuit somewhere in the harness? Literally, when I pulled the switch out of the dash and replaced the fuse, my lights came on.
Looking for a schematic for a 1999 F350 SWB 7.3PSD? Perhaps it's a relay gone bad?
Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 Won't Turn Over Or Start
I'm having issues with my girlfriends truck turning over. It won't turn over at all. I'm not getting any power to the small wire on the relay on the passenger fender or the red wire with a blue stripe off the ignition module.
I've cleaned and tested the batteries and the terminals. I've replaced the ignition switch the ignition module the starter and the starter relay on the passenger fender and I've also checked the neutral safety switch. I've checked all the fuses and relays also.
It's a 2000 Ford 7.3l automatic.
Ford 7.3L Power Stroke (1999-2003) :: Clicking Sound But Truck Does Not Turn Over
I have a 2000 Ford X diesel with the 7.3 engine. About 2 years ago whenever I would drive it during the summer, and I would shut it off and then a few minutes later tried starting it again, it would start. It doesn't even turn over or making a clicking sound but it acts like the motor is dead. The lights and all the electrical work, but it doesn't turn over at all. It will start back whenever it cools down. It doesn't happen during the winter time or when its cool outside, only when the weather is hot. I've replaced both batteries and the starter but nothing happens. Tonight it did it again and I have to wait 20-30 minutes in the parking lot until it would start again.

Wonder what color wire provides power to turn selector switch on steering column. I checked under dash for fuse 23, and all maxi fuses under hood are good. Also swapped the turn signal relay under dash and no success. I have yet to clean the pins on the firewall harness connection.
