okay so anyways i'm kinda stumped on this one. we don't get alot of 6.0s in the shop to other than the L&O, and wheel bearings. no engine work per say. anyways had a customer come in yesterday with an 04 manual single cab flatbed. apparently he had walked away from it in neutral causing it to roll backwards down hill. long story short it ran fine yesterday aside from the fact that the radiator needed to be replaced. went to pull it in today damn thing would crank over fine begin to run for half a second then die. it continued to do this so we towed it into shop. I checked both fuel filters checked for any harness abnormalities and found none. fuses all good too put modis on there to acquire a possible code. a code came up as fuel pump secondary circuit low need some help what would be my next possible step? anyone experienced this?

 

I had a similar problem while my truck was on warrantee, and it turned out to be cracked fitting on the oil pump. High pressure oil is used to operate the injectors and this failure is a common occurence creating an insufficient oil pressure situation to operate the injectors. The early 03 engines had very bad oil pumps which were upgraded in 04 models and again in 05 models. See youtube 6.0 vs 7.3 powerstroke Unfortunatly the pumps are at the back of the engine which is a real nasty to fix. Look forward to doing a lot more work on that truck.

 

You say it rolled backwards downhill? Did it hit something? Why does the radiator need to be replaced? Was it because of this roll or a separate issue? I know there is some sort of a safety switch that kills power to the fuel pump in case of an accident, if it rolled and hit something, that switch just might need to be reset.

 

Mdub you hit it on the money. thank you too botmylastford, all suggestions are appreciated. so we ran the code again decided what the hell check code tips sometimes their helpful sometimes they aren't. and sure as **** it called upon an inertia switch under the right kick panel. what is weird is that truck ran after it hit. it ran when i initally pulled it in to diagnose the radiator and then next day i guess that switch finally tripped and shut us down. ironically the right kick panel even said something like fuel pump reset with an arrow, like i said we simply don't get enough serious work time on the 6.0 other than general maintenance and front end work. after we found it and reset it, sucker ran fine, makes sense too, the back end of the truck hit the tree on the passenger side. good thing it was fitted with a flatbed but yes the impact took out the rear window, passenger door don't shut properly passenger side battery was jolted out of the battery securing bracket, pulled out the radiator; that was a first for me on the 6.0 funny thing is initially looked formidable, but after she got put back together it was a cake walk probably coulda cranked out five more of them damn things in the same day now that i know how to do it. and sure as **** the seam at the top towards the fan was leaking and the worse was the bottom right just under where the radiator tit mounts. the impact caused a pretty severe crack there. checked everything else underneath and what not and it appears everything checked out okay. this is a ranch truck too mind you, so basically if it runs and its usable then they don't want to put anything more into it.. like not having an e-brake. thank you though had we not figured it out then your suggestion would have been a good next step. how do y'all like your 6.0s?

 

Glad it was an easy fix. If the truck was warm after the "crash" it could probably still run. I know I've run mine with no power going to the fuel pump. It would start and idle, and I could take it down the road but good lord it wouldn't move out of it's own way. In my defense I didn't know there was no power at the pump until I pulled back in the driveway and checked it with a voltmeter. I wouldn't recommend running one like that...

 

Sounds like your ranch truck is just like many that I've driven and owned. Not driven too many miles, but the bodies beat up regularly, and as long as it does the job all is well. You'll run into the odd thing now and then like a fence post, a machine, or perhaps a critter will take a swing at it. The interior probably has some twine, chaff, and smells abit. One thing I'll say is that Ford continues to make Great Bodies on their machines. You will probably never turn this machine into a semi rod as many do on this site cause Farmin/ranchin just has more important things to spend money on like maybe a new squeeze shute or a new seat for the John Deere (why can't they spend more time making better seats at JD). Anyway, you rely on your machinery to start and get you there and back, and just hate runnin things into town to get them fixed. If your like me and live where it gets DAWN cold you can't have a machine that leaves you stranded in the middle of nowhere when its 40 below cause your just going to die walking home. The 7.3 you've got is a good machine, but get rid of that 6.0 flatbed fast. About the time you'll need it most it will be parked hood up. Mine is dead, and parked under about a foot of snow. Ford has disowned me after 25 Ford and forty years of being a reliable customer. There are just too many problems with the 6.0 to fix on a budget and the reliability problem makes them dangerous.

 

If you would actually read the threads instead of finding new ways to complain about your 6.0, you would know the original poster doesn't even own the truck, it was in his shop and he was working on it. Have you ever tried starting a 7.3 when it's really cold out? The 6.0 will be running far quicker than the 7.3 will be.

You keep complaining about your truck, but when we asked you for information to help you out, you brushed it off. Are you trying to fix the truck or just goign to keep complaining about it? Most of us in this section own 6.0's so we are aware of the issues they have. There are even some crazy ones who actually like their 6.0's. We are all here to help one another.

 

I know four different people with 6.0s who all enjoy their trucks very much. I know one gal who's truck has lasted over 200,000 miles with minimal care to the services as her husband suffered from a stroke, IMO is the 6.0 more "accident Prone", absofuckinlutely, but.. people still buy them. you work the bugs out on your truck botmylastford and it will be a good truck. am i personally more partial to the 7.3 yes. do I still like working on other diesel motors, yes. additionally if you knew or were partial to a 7.3 then why did you buy a 6.0? there must have been something appealing about it.

 

Touche!!! My, my, my 6.0 vs. 7.3. Two totally different breed of engines. I have 7.3 sitting next to my 6.0, but what's my favorite? I'd go with the 6.0 in a heartbeat. The 7.3 is a workhorse and it can sit in the driveway for weeks without starting. Slow on injection prime for startup, but it will crank and run. It's nothing more then a old dependable engine for working around the farm, ranch or close proximity duties. In other words, don't plan on a long field trip across the country. But that is this truck. Nevertheless, this 6.0, if maintained properly will outwork and outperform the 7.3...

 

copy that! I think their was another thread called apples to oranges ...there ya go anywho I can't deny the cold startup, the one at home stays plugged in these days at night its a 7.3. my profile claims an 02,which I do not own that's a future truck for me, we do have a 97 OBS, it runs in perfect **** shape though. the 6.0 we were working on fired up with noticeable ease. I did not notice and thought i would ask but does the 6.0 come with a block heater? another thing I was wondering is that in late 2000 I think, ford went to PMR, so do you 6.0 guys have to deal with that when going for more power. what mods do you guys make.. all the norm?
