DodgeBruhBoy Posted July 25 Report Share Posted July 25 Previous post: https://www.dodgejourneyforum.com/topic/19766-battery-died-now-it-wont-start/#comment-106151 I replaced the crankshaft/Camshaft sensors, and got the Xtool D6s for the relearn, and it was denied and still no start. So today we decided to Crack open the valve cover and take a look at the timing chain...see pics below. The timing chain is tight and doesnt have any wiggle room, at all.

5rebel9 Posted July 25 Report Share Posted July 25 As long as the timing marks align properly, I would say that the chain and tensioner guides are OK. BUT from your pictures.... You have a highly SLUDGED motor. MY suspicion is plugged up VVT solenoids for intake and exhaust cams and possibly VVT filter screen which the screen requires the cylinder head to be removed to get to it. Time to do some serious Dodge 2.4 motor youtube searching. Quote Link to comment Share on other sites More sharing options...
luzmina Posted July 25 Report Share Posted July 25 I remember a old guy always tell us, for a gas engine to run you need two things, one is gas, the other is spark, so it will be good to check what is missing of the two, from that you can have a idea if it is a sensor or fuel pump etc, of course you need to make sure you have compression on the cylinders.

We have a low voltage code still even though we replaced the battery, so there is a possible battery sensor/ground issue somewhere. I believe this is giving us the code which is preventing a startup, we are getting power to the coils, but no signal for startup (we were told thats because of the codes).

John/Horace Posted July 26 Report Share Posted July 26 Four cycles, intake, compression, combustion and exhaust. There are codes that will prevent a engine from starting; disabling either spark or fuel. Like 5rebel9 is saying, you can't look at a chain and guestimate chain slack to know if it's ok. Timing marks would have to be lined up on both cams and crank shaft to see if it's off. Weak tensioner can allow extra slack, but engine can run rough if timing is slightly out. Beyond 10 degrees not likely. How many miles on this engine? Sludge shows possible missed oil changes; so compression tester should be used to evaluate all cylinders. Are the plugs getting wet from gas ? Usually there would be a code if fuel pressure is low. Quote Link to comment Share on other sites More sharing options...

My dad and I did confirm that the timing marks are lined up correctly, there is NOT any damage or etc either, my dad used to work on cars a long time and is doing the grunt work with me. He swears everything is lined up correctly. The vehicle has 95K miles, and sadly the cars warranty ran out at 90K, we tried taking it in multiple times when it was under warranty but they stated if its working/running without a consistent check engine light it can't be covered (multiple places told us this)...as the check engine like would go on and off on occasion. Yes, the plugs are getting wet from gas and we tested the coils for power, ground, but it is NOT getting a signal from the computer to start (according to codes and research we did thats normal).
