Ford 7.3L Power Stroke (1999-2003) :: Truck Won't Start - Battery Voltage Will Keep Falling If Cranking Continues

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) :: E450 Truck Does Not Start

I bought this 16' box truck today. 7.3L, 213k, 2003. It doesn't start and the owner gave a really good bottom dollar deal for all these reasons. Showing up armed with Torque Pro and my bluetooth adapter, I proceeded to plug it in and check for rpms, HPOP, Battery voltage, etc. No power to port

Find fuse diagram the owner located and fuse 23 is the OBD port. No fuse in place. He found us a fuse, I plugged it in, viola! Power to the port, TP is in action, ready to troubleshoot.

"Charged" battery, start cranking...no start. No Torque Pro (!) Apparently, the OBD port is cut-off while cranking .... Is there some other fuse or connection that will keep it connected during cranking so I can check for RPMs (no dash gauge for it)?

As soon as I left off the starter, the HPOP on TP showed 1212 then 850, then continued to drop with in about 2 secs. I figure it is getting good HPOP and this is the momentary bleed off.

PO replaced some time ago CPS with Autozone or something in an attempt to start it. No go. I am going to take my "emergency" CPS next time to see if that does it.

Because of the cranking-cutout, I cannot see FIPW. No way to know if the injectors are firing. It had reportedly been running a short time ago (weeks maybe?) and shut off while parked in the parking lot and never started again.

Batteries are low, but new-ish starter and cranks well. With jumpers, able to maintain 10.8v or so while cranking, though it was a bit up and down. I'll take a strong charger with 200amp boost mode next time.

Fuel pump runs. I can feel/hear it when the key is cycled. It has standard Rotella 15w-40w on this 50F day. Reportedly *wants* to be plugged in to start. I plan to switch to 5w-40w synthetic as soon as I can get it home.

It's automatic, pretty sure all van/stock. Here's a pic. Dog box gives good access to turbo and such, but everything else...

One battery under hood, other under cab/body. Has green antifreeze and leak at thermostat.

My goal is to get it running to get it home, about 30 miles, then replace ICP, CPS, IPR, Glowplugs (relay already done), thermostat and top housing and hose, convert to lifetime antifreeze, oil change to 5w-40w synthetic, 2 batteries (test alternator), uppipes or gaskets, Air filter (what upgrades available for this?), UVCH, idler pulleys and belt, replace trans fluid and filter, couple tires, paint inside box, weld and reinforce rear bumper, add radio, check cigarette plugs (think cell phones and gps), general cleanup.

I will have it and run it around 30 days. If it is solid and reliable, off to West Virginia it goes. If not, I'll part it out to get back what I can from it. I am paying for it up front, they are raising donations. But I won't let them pay anything (costs only) for it until I'm satisfied.

They need to run it about 5hrs round trip once a month immediately. That's about 3k miles per year. But I'm sure they will find lots of other uses, such as building supplies, etc. I'm hoping the injectors hold up for a while.

Right now they have multiple vehicles, trailers, drivers donating their time and vehicles (reimbursed for fuel only). It would be much better to take one hauling truck and one or two passenger vehicles... hence the box truck idea.

They distributed approximately 100k lbs of food last year. Not refrigerated, not needed. No CDL needed, about 14k GAVW. The PO has offered his carport where it is parked now, or even to push it into his garage with limited tools (I can bring some) to get it to run. Otherwise...

How to get this home?? Too heavy for my buddy's tow truck from the front. Wheels too far from back of box to reach them from the rear. No tow loops in front for tow bar, UHaul dolly rated at 4k (maybe?)

Dual rear wheels. Anything else I'm missing?

Ford 7.3L Power Stroke (1999-2003) :: E450 - Shuttle Bus Won't Start After Parking For 3 Days

I am a new diesel owner. So I'm not too familiar, how to trouble shoot. I am however, pretty familiar with working on gasoline vehicles. I have a 1999 E-450 Shuttle Bus that will not start after parking it for just 3 days. I live in the area where weather has been above 90 degrees each day. I've charged the batteries, replaced them, and boosted, still no start. I have fuel coming in the bowl. And the battery meter on dash is showing that I'm cranking at around 14 volts.

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) :: 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) :: 2002 - Battery Light Comes On / Voltage Does Not Drop

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

Ford 7.3L Power Stroke (1999-2003) :: Little White Smoke After Good Warm Up - No Start

So I was on my way to work on a semi-chilly morning here in Colorado. Every day as usual, a little upset in the morning, a little white smoke and after a good warm up i'm on my way. About 10 minutes up the road while accelerating on the freeway, I hit I guess the perfect RPM range (2000-2500) when all of a sudden my CEL came on. Right as the CEL showed up, the engine introduce to me a new skip and lost a bit of power. About 5 more minutes up the road, the CEL went off and the skip went away, unless in idle. I made it to work a few minutes later and the skip in idle was apparent for sure. I turned her off and just couldn't get her to turn back on. The injectors are just not firing, no smoke at all, they don't even sound like they're trying to fire almost like no signal to the whole engine.

I replaced the CPS, the IPR and unplugged the ICP to test if she'd go. I opened the fuel bowl and watched it fill up. I checked the HPOP level, it was almost full, maybe a quarter (between half) inch from the top. No codes.

She ran great until this, outside of needing glow plugs. When I was trying to get her started it was 60ish outside so I don't think glow plugs is the issue. It sounds like the Injectors are not firing at all, whatsoever.

I will note that I had a few fuses blow out of no where that I replaced, a trail light, OBD fuse and one other in the under-dash box. I had her dyno'd a few weeks back and the tech said she made great power but sounded like she had a little issue recovering from the high RPMs but I figured my injectors are tired.

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) :: 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) :: 1998 E450 Ambulance - Hard Cutout When Cold

Here's my video of it doing it: [URL].....

98 e-450 rv cutaway with the 7.3 PSD. 219k.

Here's what I have done so far

-New GPR
-New Glow Plugs
-New CPS
-unplugged the PCM, and re-plugged

When it cuts out like the first time in the video, the accelerator pedal does nothing at all. Then once the WTS and CEL go off, it's fine again for a bit.

It seems to only do it when the engine is cold as well. After I had driven it around the block a few times and let it idle, it got better. I was able to drive it 20 miles round trip without it cutting out.

Also, might be related, it has been random on power since I got it. Sometimes I have to floor the accelerator to get up a hill, sometimes I barely need to touch it.

What to check next? It's hard to tell if it's de-fueling or if it's an electrical issue.

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) :: 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.
