Hi guys,
I've had this Ram Sport 2wd 5.2 for about 12 years with the usual issues (valley pan gasket, trans rebuild).
About 4 years ago, I wen through a similar stint with the crank sensor and coil simultaneously. Been great since until recently. The fuel gauge was sometimes not reading until you filled it up. I figured the sender was the culprit.
A month ago or so, I noticed the truck take an extra second to start. I guess I'm hypersensitive but I know my truck and when something changes. That same day, it quit driving home from the store. Wouldn't start right away but did after 15 minutes. This cycle started again a week later and on an off daily. I suspected the fuel pump and changed the assembly. I noticed right away that it now takes a few seconds to start instead of the usual half turn. For two weeks no issues except the slightly longer starting...until last night.
Truck quit 4-5 times during a 30 km trip home, including while sitting in the driveway while checking it. The fuel pump sounds fine, turns over but wouldn't start. No codes or check engine light. I think the problem is on the spark side but I can't figure it out. The coil is new.
I swapped ASD relays, etc., but all seem fine to me.
Any ideas? I'm starting to think the PCM is faulty but shouldn't there be other signs? The only other issue I noticed is the outside temperature reading on the overhead console reads fine then after turning off the engine to say pop into the store, the temperature reading is much higher (and not accurate) after restarting. No connection to the random quitting that I can see.
