I plan on storing my Cummins from November to April other then making sure coolant is up to snuff and antigel is in full and full tank and float charger what else should I do air tires to max psi to prevent flat spotting ? Need tips here guys Also going to be inside on gravel floor so dryer sheets every where lol

Hey guys, this is kind of a spin-off from my last no-start thread regarding my fuel pumps. But I had totally forgotten about another issue I had while flushing the cooling system. I had my truck idling for about 20 minutes before it shutdown, and the entire time, the all the hoses got very hot except the upper radiator hose, and coolant was not cycling through everywhere while I had the cap off, just kind of started to sizzle. So I put the cap on, and pressure still did not build and the upper hose remained cool. Is this probably a waterpump? If so, I would like to replace it while I'm doing my pumps. However a scarier issue I read, was possibly the front of the crank bei…

My 98.5 starts fine, moment i touch the peddle it goes wide open. Anyone know whats up??? Plz help...

found this useful vid of what goes on with bad injectors https://www.youtube.com/watch?v=WSwbGSeQsCo

Been trying to solve my intermittent speedometer for awhile now. It is possessed acts up under all different conditions speedometer will read pretty close to exactly double! Sometimes will do it frequently between drives other times can go a thousand miles without acting up. Shut the truck off and restart it’s all good. Checked wiring I found a repair on vss wiring but appears to be good. Replaced vss and inspected tone ring on diff. Speed on my edge matches speedometer when it acts up. Scanned and got code 74, 67, and 65. Should also add that truck has a 4w abs module but front hubs without sensor. I “fixed” this by tying front sensor wires into rear. Was acting up befo…

Need some help with intermittent starting. 1999 Dodge Diesel 24v. "Intermittently" after Wait To Start, I turn the key to start and nothing from the starter but all the dash lights work, radio, etc.. Try it again and everything is working. It is getting worse over the last 4 weeks, but I only drive it ever couple of days.

I'm new to the forum and new to dodge automatics, my truck used to surge at light throttle between 1st and second occasionally now it won't shift from first to second under regular acceleration unless you let up on the pedal. If you baby it, it shifts just fine, I just changed the fluid and filter two weeks ago and the output speed sensor last night. I tried to pull codes but there aren't any at all not even pending codes. The APPS was bad when i bought the truck back in January and I replaced it with a genuine Mopar. I am not sure where to go from here any help is greatly appreciated.

Looks like I hashed my engine. I'm not finding many good used ones, so considering a reman unit. Are there any decent reman companies out there? Checked Jasper and their prices are pretty high. I really can't justify $10k to put an engine in a 20 year old truck that's only worth about $10k......

Just got my high idle switch, super excited!! Couple questions due to other mods on the truck. Truck has 7x.011 SAC's and edge comp box. 3cyl High idle, is there any reason I should not use it every time I warm up my truck? MPG setting on the switch, is there any reason I shouldn't use it with my comp box and injectors that are around 100% over?

So I bought a used airdog off my buddy a couple month ago. It is the older version. Everything works on it but I’ve been noticing that it doesn’t keep pressure constant. I set it to 18psi at idle but if I really get on it it will go down to around 11psi on a really hot tune. Is this a sign of my motor getting weak? I’ve seen some write-ups that you can order a 4g motor from airdog and it will fit on my airdog. Is this drop in psi normal or is it getting weak? Or is their something I can do to keep it at a more constant psi all throughout my throttle position?

I finaly got a boost gauge hooked up (slow poke). Whats your boost gauge read when you are just cruzin 'bout 60 on a flat hwy, just light throutle cruzin for mpg, no grade?

Got me a better gauge today and checked my pressure on my lift pump. Got a 0 to 30 psi gauge.On starter bump i get 14 psi.start engine and run im getting 12 psi at idle.Put truck in gear, hold brake and acelerate i run at 9 psi when really pulling hard.So I'm hoping that is good enough for my stocker around town.OH yeah! I never realized how stupid I am.I realized I have a intercooler on my truck! Duh! I was thinking it was my air conditioning condensor.Like they say sometimes you can't see the forest for the trees.

Good evening everyone, This morning I went to start my truck and it just cranked but never fired. I noticed smoke coming from engine bay and it was coming from ground cable from passenger side battery negative post that connects to body. It was extremely hot and was smoking. Truck started and ran fine yesterday. Really need my truck back up and running, please help! Tim

Damn. Recently pressurewashed and thoroughly degreased my engine. Yea, I know once the engine is squeaky clean this the best way to spot leaks. So, I have an oil leak where the vac pump / ps pump flange mounts to the rear of the timing case. Dammit! Hard to get to. Has anyone taken this assembly off to change the gasket & resolve an oil leak? My first gen has a leak in the SAME EXACT area. I tried to remove the assy on that truck and ended up frustated. I'm not fixing this issue on the old first gen, but my 02 is one sweet truck so I'm inclined to fix and keep it clean. Any tips or step by steps? Picture attached. (picture taken while i was …

So just a general question I have an hx35 want a good filter was wondering if putting a cold air filter directly on the turbo would be good or bad seen a few around need some opinions thanks

So Ive had the Gould pump reseal kit for awhile and decided since I got all this downtime I would go and rebuild it this morning. Everything was goin great until I started to drive the seal retainer out of the housing. I cannot get the damn thing to budge. Using a big dead blow and the provided driver tool, even used a 2x4 and a 3lb sledge and that sucker wont budge. Anyone had this issue or any tips/tricks?

Is there a way to tell if my Killer Dow Pin has already been repaired with the KDP Kit?Were all Cummins 5.9 24V 1998.5 manufactured with the KDP problem?Did Cummins ever solve the KDP problem during assembly?Any information will be appreciated, this KDP issue could be a very expensive repair which worries me.

I am a newbie to Cummins diesel trucks so bare with me and my questions. I changed my fuel filter today, once the old filter was out I noticed debris in the bottom on the filter housing so I cleaned that out best I could. I had to drain the housing so it took a few key cycles to prime again but she did restart. While doing this I noticed another inline filter before the LP that I'm sure is not factory. See pics below, before and after cleaning out the debris, last one you should be able to see the inline filter down near the frame. Also, there is what seems like a larger line from the LP to the filter housing. Is this just an adapter or is it what is con…
