I currently have 126k on my 2007 Dodge Ram 1500 5.7. I just recently did the famous Cam swap with items below;
2023 @ 126k miles
Replaced old 16yr old OEM with Delphia LONG CRANK , start wouldn’t start again after turning off unless I cleared the code. PO440. Now I did replace this without unhooking the battery. I read you may need to replace the Crankshaft sensor too. Before I did that I thought let’s try and replace it with another one incase this one is defective. Went and purchased a Duralast that had instructions in the box that recommended swapping the crankshaft too. I replaced the 1st aftermarket one out with this new Duralast with no change. It started fine, but check engine light every time it started. Didn’t run rough at idle. Would also start after turning it off. Now I replaced the old OWM crankshaft with a new Duralast Cranshaft and it runs even worse like it’s going to die. I’m getting PO339 & PO340.
Any help would be great! I’m stumped!!
