Ford 7.3L Power Stroke (1999-2003) :: Partial Crank And Intermittent Start
Anyway, I went out to start my truck just now and I'm getting a weird symptom.
The truck gets partial revolution and then to me it seems like the starter bendix pulls back in prematurely and this nasty clank and then a slight "zing". all within a second.
If I try a few more times, it seems to fire. But all the attempts before it fires sound pretty nasty to me.
Does this sound like a symptom of a bad starter/bendix?
A little further history, my excursion was broken into several years ago and they stole my pioneer head unit, in doing so, they forced the shifter down and since then it has been a little "loose". I'm wondering if it could be a neutral safety switch on the transmission?
Anyway, I'm getting ready to order a new neutral safety switch but wondering if I should go ahead a purchase a new starter as well?
Ford 7.3L Power Stroke (1999-2003) :: Intermittent Crank With No Start After Oil Change
I did a bunch of reading before I bought this truck, and the seller said it really just needed a new battery as far as he could tell... When I bought it, I drove a considerable distance with no problems, other than it seeming to be a little sluggish with acceleration.
I have not seen any leaks anywhere, and all of the visible reservoirs appear to be nominal. No odd exhaust (really clean/invisible, in fact). No weird sounds, and running engine has a pretty even sounding cadence.
I initially changed all of the shocks because the old ones appeared to be original and were severely corroded/rusted. There is some surface rust elsewhere as this truck was apparently used in agricultural setting.
I replaced the battery and it was starting fine for a few weeks, but it would intermittently crank with no start, and would sometimes die within a few minutes after starting. I also charged the a/c with 134a, and it is blowing cold.
So... yesterday, I changed the oil, and installed a Fram Tough-Guard filter and precisely 15 quarts of oil (dipstick shows right level). I also changed the air filters, and disassembled and reassembled the air-cleaner to turbo hoses. While the hoses were disassembled, I took off the relays (AIH/GPR) and reinstalled an aftermarket GPR (crappy foreign-made one). No start. Several times. I reinstalled the original GPR. No start. Several times.
Even tried to jump it from my running Explorer. Still no start. (When I say no start, I mean that it will crank, but not turn over).
I am scheduled to take this truck into the dealership tomorrow for the recall issues (CPS), but I can't drive it there right now. Did I mess something up with the crappy GRP? Why wouldn't it start after reinstalling the original?
Another observation -- I had my batteries tested just now, and they are around 60%. I have ordered a new Alternator because this one looks original and is likely not charging the batteries. Still, I figured if I jumped it, it would start.
Ford 7.3L Power Stroke (1999-2003) :: Intermittent Hard / No Start Now Crank But Not Firing Up
My wife has been telling me our '01 E-350 (Econoline) with 7.3 is taking several attempts to start in the mornings, like it's not even trying to fire. It will crank like wild but no fire and then it will fire usually and sometimes run a little rough but no always.
Tonight she called me from across town and it won't start at all, cranks like wild but won't start, chug or anything.
The WTS light is working fine, the truck runs great and idles smooth all other times, just been giving grief when starting in the mornings (warm outside 70 degree plus ambient temp). I haven't had the truck do it to me but she has explained it well enough.
I do get a SES light for overboost when I run it hard (PHP tuned) but it always goes away and hasn't caused any issues. Could this be the ICP acting like this? If so, is it true that I can just unplug it and the truck will start by using default pressure?
Ford 7.3L Power Stroke (1999-2003) :: No Start / Oil On ICP Sensor Connection
I have a 2002 F-250 7.3L with 175,000 miles and it died on me July 30th. Here were the symptoms when it died:
Engine was sluggish at standard RPM about 1300-1500 going about 45 MPH, so I stepped on the gas and it seemed to go away. About another 5 miles down the road and starting from a stop, the same thing started happening. The entire truck seemed like it was going to shake itself apart and with the peddle at half throttle it revved to 3500 rpm and didn't shift into 2nd gear until after about 5 seconds at that RPM. After it jerked into 2nd gear the engine dropped back down to about 1000 RPM and started shaking violently again. At this point I managed to make it to a shopping center and then as soon as I let off the gas (still shaking), the engine dropped to 500 RPM and after about 15-30 seconds shut off. When I got the truck home I managed to start it one more time but it shortly stalled after about 15-30 seconds, again it was hovering around 500 RPM and still shaking badly.
Here is what happens when I try to start it:
From 0-2 seconds, truck goes through a normal cranking rhythm and sound.
From 2-10 seconds, it slowly tries to start itself back up but it sounds like it is only firing on a few cylinders, I'm guessing maybe 2-3.
I stopped after 10 seconds in fear of burning out the starter or killing the batteries.
Troubleshooting:
Removing the connection to the ICP sensor, something I read that might at least let me start the truck, which is how I found the oil on the connection itself. I also noticed a little bit of what looks like oil on the some of the wiring harnesses in the surrounding area. I also checked the fuel bowl and it is filled with fuel.
Possible solutions?:
From what I have read on the forums I am guessing that it has something to do with the ICP or the IPR sensors. I also believe that it is a sensor related issue considering that the truck won't even start. I am completely off track. I am going to start working on it full stride this weekend. I have been vehicle-less since the 30th so I'm trying to get this fixed asap. I don't have any codes, I am going to try to get a coder this weekend.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Intermittent Starter / Whirring Sound When Crank
I have a 2001 f250 ext cab long bed 4x4 that I use as a feed pickup. I have had it for about a year now. one of the issues I have noticed since I bought it is the issue I am having with the flywheel/starter. Its very random like maybe I have a missing tooth or something on my fly wheel. but every so often when I would go to crank my truck over it would just make a little whirring sound and nothing happen ( like my starter gear isn't sliding out and engaging my fly wheel.
After looking through my inspection cover I noticed I had a little wear on the sides but no teeth to my knowledge broken or stripped off. I noticed my starter had one bold loose but other two perfectly tight. It was also covered in oil and dirt from my truck sweating horse power I decided to replace my starter and have my original ford starter rebuilt. I replaced it with a NEW oreillys starter. I noticed it cranked about 5 times as fast but again every 10-15 starts I am getting the same no start. any thing I am over looking?????
Ford 7.3L Power Stroke (1999-2003) :: Cold Crank No Start
I have an 02 f250 230,000, first 7.3. I've owned it since Oct and put less than 6,000 miles on it. I have another cold crank no start. New glow plugs and Glow plug relay last weekend. Worked fine that weekend. It sat all week, then crank no start fri night, it was like 70 degrees for the high that day. Plugged it in over night and it started. Did not fire right up cranked it for a couple seconds. I drove it all day, started every time. Valve covers have 5,000 miles on them. Fuel Filter heater fuse not blown. But don't know how to check it for sure. And don't know where to go with it from here. Getting frustrated with crank no starts. No troubles found.

I got a 2000 7.3l with 400,000 miles on it that decided to just not start anymore after I parked it for a couple days. Its always been a hard starter due to needing glow plugs but I can deal with that. it doesn't even try to fire anymore. I replaced the CPS (my tack bounces when cranking). The ICP has oil in the plug so I just unplugged it for now till I replace it.
I pulled the IPR and cleaned it really good and bench tested it with 12 volts and could here it clicking so I put it back in. I can get under the drivers door with the key on and hear the fuel pump running. I gain oil pressure on my dash gauge when cranking. I check all my fuses. my WTS light comes on . I just don't have any fancy scan tools to make this easier. Also just cause I was feeling lucky I just went out and bought 2 new batteries for it yesterday so we are good there.
Ford 7.3L Power Stroke (1999-2003) :: 1997 - Crank But Won't Start?
I have a 1997 F350 7.3 with standard xmission. Have not messed with it since Oct of last year. Then it would crank but no start. Now when I turn the key there is no wts or nothing the gauges move, and tach moves when cranking, but nothing else.
The cam and crank pos sensors have been changed. The high pressure sensors changed. Now when I hook it to the AE it says cannot connect to truck. Where I need to start? Have checked all fuses that I know about.
Ford 7.3L Power Stroke (1999-2003) :: Won't Start / Just Crank And Tried To Fire
Friend's 2000 7.3 wont start, just crank and crank tried to fire but nothing in the cold leave it plugged in and it starts leave it in a shop over night and it starts with a shot of either, he is a truck driver and the truck will sometimes sits for 6 weeks at a time this time 2 weeks before I touched it. He wanted me to install a fuel pump so I did and started the following:
Cracked fuel lines to see if I had fuel psi at both heads
I tested glowplugs they all read at 0.3 on all 8
I have power to harness as the same at both sides of the relay
RPM tach jumps
Oil psi gauge rises
Using my phone I can read hpop and 2000 at cranking (how accurate that is im not 100% sure)
All fuses good
Ford 7.3L Power Stroke (1999-2003) :: New Injectors - Crank But Won't Start - Low ICP?
So I got all 8 injectors upgraded and excited when I get them back I put them all in in kind of a rush. And in that rush I left the cylinders full of excess oil. So obviously when I tried to start it hydro locked. Angry at myself. I kept trying to crank hoping it would fire and just shoot that oil out. Nope, so I went back to taking all the glow plugs out and firing it all back out. Put it all back together then tried to fire her up. Took a minute but she started and I let it run for a while. Hit the gas a few times and then it died. Couldn't get it started again. It would just crank, I checked the icp and ipr and the icp did not build above 35 psi and the ipr was at 98.04% so I just figured the o rings blew out when it hydro locked.
So I took it all back apart put new o rings on, took my time and put it back together right double checking everything. Got it all back together and went to start it, it would just crank around 160-170 rpms, battery voltage at 10.6 icp built up to 140 but now it won't build past 40. Ipr still goes to 98.04. The engine ran just fine prior to injector change, I put a new upgraded hpop prior to injector change, new ipr, icp, cps. Everything checks out, but it will not build oil pressure while crank I've killed a set of batteries then went all out and spent 350 at napa for some optima red tops. I did notice the cylinder 7 injector is the AE injector. It suppose to be in cylinder 8, idk if that's affect the oil pressure building up?
But as far as I know, I'm not building oil pressure. So idk if the hydro lock could have ruined something to keep it from building oil pressure?
Ford 7.3L Power Stroke (1999-2003) :: 2001 - Crank But Won't Start?
i have a 2001 f250 7.3L PSD. it turns over but will not run. replaced the CPS , starter and the #30 fuse. IPR is new and all injectors are new, new gaskets and harness and new glow plugs new batteries. still just cranks and cranks. no oil pressure build up and no tach movement, oil level is good in HPOP. What could it be?

So back ground is as such. Truck started fine before I replaced the hpop with t500 and did the driven diesel regulated return. I have double checked everything is plugged in. Now when I try to start it cold it will just crank. Yes I get smoke and oil pressure both places. If I give it a shot of ether it will start right up and run fine all day. What am I missing? Yes I know ether bad.

Found icp sensor with oil in plug and codes p1211 and p1212. Icp sensor reading 0 pressure. Changed out icp sensor. Still cranks no start check oil level in hpop resverior, check with brake clean spray nozzle and no oil on it. Filled resverior with oil. She tried to start. Had to put the charger on her and she finally lite off and came to life. Questions, how would that resverior empty out? Was it because I pulled that sensor? Is there s check valve in that resverior hanging up?
View 2 RepliesFord 7.3L Power Stroke (1999-2003) :: F350 Won't Crank At All / When Turn The Key To Start Power Drops
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.

I've replaced the alternator and starter recently and both batteries and the truck ran fine befor that. But it sat for roughly 2 months and now it seems as if its not getting fuel. Will start with a shot of ether but will die as soon at it burns it off
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Long Cold Crank / Hot No Start
I have a early 99 f250 super duty 7.3l and it's giving me fits. about a month ago the truck started to do a hot no start. drove truck for about a hour. Shut it off and half hour later no start. Let it sit over night and would start with long crank.
Changed CPS no change. Pulled tuner and set back to stock. No change.
Changed fuel filter, no change.
After reading forums changed IPR and truck started and ran great. About a week ago back to the same problem. Battery's are about 2 months old. Oil change and oil filter a month ago.
Checked the hpop reservoir and its 1/2 from the top.
Checked fuel bowl and it has fuel. no sign of oil in it.
Drained bowl and watch bowl fill back up. seems to fill quickly.
Pulled passside valve cover to check for bad orings while cranking.
Every thing seems fine. have not done driver side yet. used FORSCAN and ran buzzed test on injectors and they all buzzed what seems to be about the same. ran test couple of times to make sure. this morning I ran a live scan while cranking and this is what I got right before it started. ICP 660.6psi, IPR 64.84% and RPMs 227. took 8.86 seconds to start. after work scaned again for hot no start and this what I got. ICP 292.9psi, IPR 55.86%. and RPMS 203. unplug ICP and no change. still will not start. one thing I did notice when plugging ICP back in I looked down in side at the pins and can see what seems to be bubbling around one of the pins. the pig tail has just the slights sign of oil.
Ford 7.3L Power Stroke (1999-2003) :: F250 - No Start / No Sound When Crank The Key
I have an electrical problem on my 2003 f250 7.3 diesel. Sometimes it starts and sometimes it doesn't (mostly doesn't). I have two new batteries in it and have cleaned the grounds at the batteries and at the engine. When I go to start the truck all the lights in the dashboard work and it dings at me but when i crank the key nothing. I wanted to see if i was getting power to the starter and when I put my multi-meter down on the ignition wire on the starter and put my ground lead on the chassis bolt it starts every time.....I'm thinking this should not happen?? Is that a bad ground or a short or something else?
