- Today I am fitting a now ignition coil. If this does not resolve the P0305 Fault Code issue, I will need your help!

You can also look at changing the mds sensors they are under the intake bolted into the block they are like 30 bucks each
Just look for a mile motor. Used from a wreaking yard here in the USA. There is a place called Lkq auto dismantling
Hey Dave . read the ECU codes, check wire diagram and trace from the coil pack to the relay and relay to the ECU your checking for power delivery and resistance It sounds like a module problem
since you were getting a fault only on #5 and now is it still the same cylinder or is it multiple cylinders good luck.
That's my next thing to do along with the valve seals and head gaskets I would change all sensors before I start to over haul the motor. These motors are some of the best built motors I have ever seen they take a beating
they were the best in the older years until fiat come messing them up.
Go to live data and check the fuel trims see if running around 0% if they’re + adding fuel you might have a big vacuum leak , spray around the intake with something see if it revs up
I had to get a new computer well it was used and reprogrammed for my vin they also program the ones u bring in for 75.
Best investment might be a Crate motor. At least short block.
check your valve springs. a friend had the same problem with his ram. had a broken valve spring
I use only full synthetic oil and its supposed to be 5w-20 I always get 5w-30 unless they only have the 20
Did you change valve seals?you could have some oil leaking through the valve seals I have to do mine had to buy a special tool to remove the springs though.
Yes, I changed the valve seals. I also replaced 8 valves and re-lapped ALL the valves when I rebuilt it.
I’m hoping it’ll be something easy to fix!!! And not that I know but are you working the device ( scanner) properly???? If it could only be that easy!!!
The scanner only reports, it can't repair anything.
maybe a knock sensor
Seems coincidental that right after you got your scan tool your crank sensor died now this !!?? Does the 2010 Ram have cylinder deactivation? I think I would try a crank sensor from oem before I went much further. But I'm a plumber so what do I know?
Hey Brian. I’m trying one more crank sensor, but a quality one this time. Stay tuned.
I hate seeing that p0300, I know the pain. The first thing and low cost in my opinion is that we need to find in your scan tool the misfire counter report. Usually under the live data or in a separate section such as ODB misfire counter. That counter like in my scan tool will show you the cylinder(s) that are contributing to the p0300. Once we know that we can look into next steps, such as a compression test on the reporting cylinders. Blue smoke, if I recall correctly usually means oil. With the compression test a borescope of the cylinders will help show if there is something getting in such as oil. I'm keeping that crank sensor in the back of my mind as it is odd it started when it was replaced. I would be willing to send you am OEM one or funding for one. Also does your tool have special functions? If yes do you have a crank sensor relearn? If worst case it is something like a failing lifter, it could be redone, as I am doing, but could also be easier to get a short block crate motor, or one from a low milage 1500, but to early to make that call without some more testing.
You might be right about the crank sensor. It's just way too coincidental right?
@@ScottRods Agreed, as just because a part is new does not mean that it is good.
Cost me 500 bucks but I could have went to a junkyard got one there for about 90 and paid them to program it for 75
I have 395000 miles on my 2008 5.7
i have the same 2010 truck and same problems i feel like burning the damm thing, its very frostrating to fix as you replace one thing another pops up in its place. i was a dodge man for years now i feel like going to ford.
Turned out to be a bad pcm.
Hey Dave check with Sky over on the Reignigted TH-cam channel, he's Dodge tech with tons of experience.
PCM ?
Wheres the 36
It's parked in front of the broken BMW. It's my daily now, lol.
Not an expert but have some electronic experience. 85% of the time the problem was caused by the component before, that controls the failed part. The cam position sensor was it a quality replacement part ? Some replacement parts are not the greatest . Find it strange codes are different with every test keep adding more failed components. Gd luck Dave
No, I have not yet invested in any quality part.
Imagine all the cussing and cursing off camera 🤬
Yes, indeed.
@@ScottRods i,m doing it with mine right now lol.
