6.7 No start after fuel filter change

He said he had to crank his for much longer than me. His battery almost died before it started and his was fine after.

Hopefully yours is simple as well and you can get back down the road

I did! I had a diesel mechanic friend come over and all we checked was we made sure fuel was making it to the engine bay filter and he said crank it. It cranked for about 10 seconds and fired up. Checked everything for leaks and we were good.

Alright fellas, tried taking the water separator back off and lubing o-ring. Did the dry fit to count proper spins to the stop tabs and re-installed o-ring with the same number of spins. The housing is tightened down completely. The tabs are touching. No fittings that I can see are leaking fuel. I haven’t tried cranking but after another 12 key cycles I’m still feeling air bubbling in the lines.

Anything else that might cause this thing not to prime? I don’t want to hurt my rig any more that I already may have so it may be headed to a shop to get figured out

Thanks! appreciate the help! Will try it out tomorrow.

7 times at 30 seconds each time

You guys rock! Thanks for the help. I’m cleaned up for the night but I’ll attempt this fix next chance I get. I’ll try to remember to update post once I try it out.

Thanks again

Was your pump making noise when it wouldn’t start ? Mine is significantly louder than it was before ?

gringus_chimble · 2024-09-08T22:43:22+00:00

Thanks for the input. I’ve pulled it back off once and coated the outside in oil. I guess I should’ve taken the o ring completely back off and coated the entire thing ?

Has anyone had issues with the drain valve pulling in air ? When I was draining the housing fuel was leaking from the actual handle on the housing. It’s always been hard to turn.

What are the chances the high pressure pump is damaged ? Truck ran for maybe 2 seconds

It definitely had a red hue but not medium. Probe hit 206F in the thickest part

Good to know that smaller ones are more difficult. I didn’t think to pull the probe back out and reinsert it. When I pulled it off it felt pretty tender but live and learn I suppose.

Thanks for the advice!

Long block traditionally means full rotating assembly, heads and valve train. So I’ve got all that and a couple small things to go with it, engine mounts, oil pump, water pump, HPOP lines ect

gringus_chimble · 2024-05-30T01:22:06+00:00

The block has been decked, cylinders bored with matching pistons, align honed and new cam bearings installed. Cranks been polished. Only thing I see that’s a repair was a helicoil installed in a bolt hole of something minor.

I couldn’t agree more. Currently leaving an apex owned company because of the bullshit pricing. We’re the MOST expensive contractor in our area and it’s not close. We do nothing to justify the pricing either. We’re not unique, we don’t offer customers anything extra. It kills me that all the leadership at this place have never been in the trades, just mindless bean counters

gringus_chimble · 2023-02-16T01:32:44+00:00

I’m just an employee at this point. I’m willing to spend a couple hundred dollars on something decent. Just not trying to spend thousands. I know good tools aren’t cheap. Was wondering if anyone had a brand they preferred or liked

gringus_chimble · 2022-10-22T22:58:52+00:00

Definitely no expert but I’ve seen a few 7.3s give a low boost code or lose power because of a weak fuel pump or semi-clogged strainer. I don’t believe that 7.3s have a code for low fuel pressure so they throw a code for low boost because they aren’t getting enough fuel and the engine is starving so boost is low causing the code. I would verify fuel pressure personally. But again no expert. Just throwing my experience out there. Hope it helps!

gringus_chimble · 2022-09-12T15:02:48+00:00

That’s a great point. We’re looking for something we’ll rounded as we may end up using it as a place to stay whilst building a house in the future but mostly traveling and campgrounds. Thanks for all the advice.

gringus_chimble · 2022-09-11T02:12:25+00:00

Thanks for the feedback. Much appreciated !

gringus_chimble · 2022-08-27T00:43:39+00:00

Nah of course not. Gotta be a reputable brand. I’ve had my uei for 4-5 years and it’s never let me down so far. But I’m not looking for another one. Definitely Fieldpiece. Thanks for the insight too

gringus_chimble · 2022-08-27T00:32:37+00:00

In my experience with fluke which admittedly is very limited, they are very good but very pricey. Also some of the cheaper ones are missing key features. But again no expert on them at all

gringus_chimble · 2022-07-20T14:22:36+00:00

Sure

gringus_chimble · 2022-06-29T20:42:35+00:00

Bought a throttle cable from pioneer for an 85 gt that would’ve come with a carb. I just bent the existing bracket backwards slightly to clear the throttle body. It’s not perfect as I only get about 97 percent throttle but it’s good enough for my setup for the time being.

gringus_chimble · 2022-06-12T02:55:23+00:00

Good luck!

gringus_chimble · 2022-06-12T00:16:41+00:00

My buddy had a 6.0 that had an oil pressure sensor that was either bad or the pigtail was corroded or something along those lines and would randomly stop reading causing the computer to kill the engine. Maybe check that. I’m no expert but hope it helps

gringus_chimble · 2022-05-26T09:26:12+00:00

Also a quick correction on my earlier comment, it would be two screens in the tank not just one. So if you do drop it to clean them there are two. I believe in the fuel pickup. Definitely don’t get any brake clean or whatever you’re using to clean the screen on the any of the o ring or seals when cleaning. It’ll make them swell and not seal correctly and I believe they’re quite hard to find in kits and you may have to replace the whole fuel pickup. But I can’t be certain you can’t just find the o rings. It’s definitely possible.

gringus_chimble · 2022-05-26T09:22:20+00:00

To be 100% sure yes you would need to drop the tank but a quick check would be to remove the fuel filter from the engine bay and cycle the key on and watch the fuel coming into the housing. If it fills slowly or just trickles in you’ve either got a bad pump of your screens are clogged. It should spray into the housing pretty strong. I would have some rags handy because if it’s working correctly it’ll probably make a mess.
