Ford 7.3L Power Stroke (1999-2003) :: Got Error Message P1670 / P0381 - Low Oil Pressure - Won't Start?
Nov 23, 2015
I had new glow plugs installed 3 weeks ago. Ran fine since. Today, first cold day. No start, oil pressure gauge does not move off zero, interceptor reads ICP 126. Oil level is good. WTS light does come on. Checked fuse 19 as I saw on another thread, it is good.
P1670 and 0381. My ford software is down, trying to reinstall. As soon as it is reinstalled, I can go thru the step process?

But it starts. '99 F250 PS. Had code P1670, cleared it. No other codes. Started truck back up and ran KOER test with AE(which I'm not very good with). The code did not come back. It is hard to start plugged in cold or warmed up. I have WTS light and it goes out(glow plugs are original). RPMs are slow to come up (almost starts before it kicks in). Doesn't matter if fuel tank is full or not. Oil level is fine. Batteries are charged and check good. Starter checks out ok. Buzz test was ok. Now when I run KOER do I need to do anything other than hitting the initiate button?

On the way home from work today as I pulled in there was a pulsating under when I pressed the brake pedal and the ABS light appeared on the dash. It didn't pull to the right but it felt kinda odd. When I start the truck, the ABS light comes on with the other indicators, goes off and then comes back on a split second later.
Haven't had any issues lately, and haven't had it worked on lately so not real sure where to start. I checked the VSS sensor on the pumpkin and it was relatively new, which means the prior owner had replaced it. Master cyclinder is full of fluid. I pulled the codes and it returned P0603 P0671 P1670.
Just sprang up out of nowhere. The speedo was not acting squirrely, just the brake pedal pulsating intermittently. Is there a VSS computer I need to replace?

Ok so this past Saturday I drove the truck about 40 miles round trip to get fuel and came back to the house to pick up my tux for a wedding I was in that afternoon. On the way to the wedding I went about 10 miles down the highway doing about 65-70 mph and all of a sudden I heard the engine just shut off. No stutter or anything.
Went to restart and nothing just cranks. had to call and get a tow back to the house real quick and grab the excursion and head to the wedding. When I got home on Sunday I hooked AE up and started to poke around.
RPM around 150-170
Batt Voltage 11.5-12
IPR up to 65%
ICP 0 (have tried to unplug and start) (sensor is dry no oil bleed through)
Buzz test is good all injectors are strong. I am sure it is the lack of oil pressure but I dont know why. I can get more info from AE if needed.

I am towing my 5th wheel RV trailer and just started out on my journey. I've driven 350 miles. I stopped for a breather for about two hours. Now my truck won't start and a low oil pressure indicator beeps in the message center. My truck is a 2011 F250 super duty 6.7ltre diesel. Recently had oil change and fuel filter change.....

I have a 2003 1.8L Volkswagen Passat which I hate to say I've been lax on taking care of. In the past year I've been good about getting the oil changed and using fully synthetic oil. I am now getting an error message that says STOP Check Oil Press. Stop Motor. I took the car to my mechanic who can't tell me exactly what's wrong. From what I'm reading here, it looks like I'm dealing with "sludge."
My car is at a little over 60,000 miles and I'm wondering what to do. I don't mind spending the money to fix the car, but I really don't know how to figure out exactly what's going on, and what I should do. The mechanic I took the car to is going to completely empty the oil and then get a gage of the true oil level...

My 03 F250 6.0L Starts and Runs fine but will never illuminate the glow plug/ wait to start light? Scan tool test on GPRM and tells me everthing is OK. Cleared all codes, turn on key, no WTS light and throws P0381 DTC every time. What my problem is?

Story starts when I was cruising down the freeway and the truck cut out, seemed like a CPS or Injector related issue - seemed like a whole cylinder bank cut out. Stopped truck on shoulder, she shuttered and died. Turned truck off and restarted, ran like a top for about 4 miles then did the same again. I restarted it again and drive it straight home, ran like it I usually did.
As soon as I arrived home I did a little research and learned to start with CPS. I replaced my grey CPS with a new, Ford grey CPS. Truck fired up, ran the same that it did before - not the best idle but at 302k I was content. Drove it for a few days and it did it again, hobbled the truck home, although it did do it a few times and the last time it did it was really hard to start.
I replaced the IDM through NAPA. She's a work truck so I wasn't going to splurge for a Swamp Unit, the NAPA one came with an 18-Month Warrenty. She started right up afterward, the smoothest idle I had ever felt and she ran great, except for an SES. I ran the code and it was an IDM code, ran a buzz test and it pulled injector #5 high/low error, but it buzzed (a bit quieter than the others).
Here's the weirdest part, when the motor is cold the SES is constant, but as it warms up it only shows under power and sometimes flashes off at certain RPMs (1700-1900 and 2100-2300) and turns off when engine braking (TC locked) returns at idle. NO engine lights with the old IDM. I've checked the wiring to the injector from the 42-pin to the outer connector. (.6-.7 ohms, what my meter reads without any loads) Injector (from outer connector) reads 3.2 ohms. UVCH is less then 2 months old (GP issues) injectors have less than 5k on them.
Why? New injector solenoid? Bad IDM? Is it possible my last one never fired #5 and it got stuck? Or did my old IDM fry #5? Also I'm going to keep driving it and maybe it'll clear up, there was one drive I took where it cleared up completely. I've done some extensive research on this an i'm stumped. With the new IDM the truck has run better then it ever has.

I went and got my truck smog and it failed because of this code. I then changed the sensor cleaned out the tube and I still can't figure out how to get rid of the error code?

I have a 2016 F350 i purchased about a year ago and now has 7500 miles. last night it tossed up a low fuel pressure message and then de-rated then wouldn't start, i heard a crazy humming sound before it shut off. they pulled the fuel filters "claimed it was gelled" even though it fired right up once it got to the dealership. the fuel i run is good to -9*F and i use ford anti-gel on top of that. So they changed the filters and it wouldn't start again. now they are dropping the tank. So, I am not sure what they are gonna find but I am meticulous when it comes to pulling all the foil off of the anti-gel bottle before even opening the cap. I don't know what could possibly be in the tank to cause the issue.

Driving back from the funeral and get a Low Fuel Pressure Warning message PPP up in the info display. No CEL's etc thrown (yet?). I have PM23A anti-gel in the tank already but stopped for diesels no poured more in. At the same time, I hear what sounds like an electronic motor making a whirring noise in the dash around the area of the under-hood fuel filter. Also sounds like there is the same noise from the back fuel pump. I assume it's the fuel system starving? Calling the dealer now, but going to continue pressing on cautiously until the truck tells me otherwise.

I have a 2003 F-250. For 8 months now we have been trying to get my truck to start. We have replaced the High pressure oil pump, Oil cooler, PCM, Main wiring harness, FICM, Injectors,, ICP, and IPR. Still we are not getting enough pressure to start the truck. What is happening is the pressure will get to about 340 and will not increase from there. If we are to disconnect of one the connectors from the FICM the pressure will reach 640. Now we are able to get the truck started with ether, but will not remain started. As of right now we are still trying to figure out what is causing this problem?

Well I thought my truck was 100%, and I was going to installed a Chip. I decided to get my Forscan up and running to check and make sure.
The Buzz test Passed with no problems.
The cylinder contribution did not pass. I got error code P1464, which Forscan said that #8 failed. FYI, I turned the A/C on and the test failed. I ran it again with the A/C off and it failed again. I might have the wrong code
I then went to where you could select the gauges to view(PID's). And I saw where you could select all the cylinders injectors individually. I forgot what it was called, but all injectors were reading close to 0.0% at idle except for #8 it was reading 5.55% to 5.88%.
I am hoping this is good news, since I rather the injector be bad then a piston ring or valve. I just got the Forscan and was wondering what other test or other things I could check to narrow the problem down before removing the Valve covers. The truck runs great and there is no miss and it turns over smooth. No blowbye, just runs great. It is a 2000 F-350 dually with just over 202,000 miles

I'm trying to get my truck smogged and having problems w/po475. A friend of a friend said it was the DFPE sensor. So I bought one but can't find where it goes. On YouTube it is only listed for F150's and gas motors it seems. I have a 00 f350SD 7.3, do I even have a DFPE and if so where is it located.

2000 truck, 334k, automatic 2wd, stock. Have low power, 11psi max.
Permanent p0472 code, can't clear it even temporarily. The moment I turn the key to Acc, code is there. It's the only code showing on Forscan.
Tried 470ohm 1/2watt resistor, in two turbo pedestal sensor connector wires, no change. Forscan shows 0.0-0.6 psi EBP value when running.
No change with pedestal sensor plugged or unplugged. Resistor or not. Truck starts and runs good, low power is the only issue.
Sensor and tube are new. Seems like wiring is bad, where to look next to track this down?

Low power on my 2003 7.3 F350. The truck runs fine but I can tell it is low on power (seat of the pants). I figured it to be fuel related so changed fuel filter and oil with no change. When that didn't work I installed a fuel guage and this what I found. Key on no start fuel pressure 45 psi. Start truck the pressure will get up to 61psi. Under a load it will drop down to the low 30s. I have dropped the tank mixing chamber screens clean and so was the tank. Changed fuel pump and now under a load it drops to the high 30s. Does this sound like the fuel pressure regulator is leaking by and causing low pressure under a load? Truck is stock besides superchips 1705 programer.

My high pressure power steering hose just blew at the "B" nut at the pump. Meaning, the fitting is still in the pump but the line is out. Do I need to replace the whole line or is there a retainer I can swap out?

I just replaced my 3rd HP power steering line last night( 3rd in 300K, always blows the same point....fitting comes apart where it attaches to the pump.
I'll start, mine have gone about 100K plus or minus 10K, almost thinking about making it a 100K maintenance item.
