1998 Ram 1500 5.9l Cranks but won't start
Hoping for some advice. I'm having a couple of issues and don't know if they are related.
1) A month or so ago, this started: If I left the truck parked for a couple of days the battery would be completely dead. Dead as in no interior lights, no dash lights..nothing. Could charge it and it would do fine as long as I drove it daily. The battery was 5 years old, so I assumed that was the problem. I replaced it, but still have the same issue.
2) I drove it yesterday, it started and ran great. Today, after changing the transmission filter and fluid, I went to start the truck and had a dead battery again. Completely drained. Hooked up the charger and and a jump box to start it.
3) Won't start. It cranks, but won't fire.
What I've checked so far:
- Fuel pump comes on and I have fuel at the fuel rail valve.
- I get spark at a plug, but it's a yellowish orangish spark
When cranking, it doesn't seem right to me. Almost like it's out of time or something like that. Not a smooth consistent crank / spin.
Any thoughts or suggestions would be appreciated.

I am also trying to figure out a rough idle / trying to die thing after it sits idling for a few minutes. I didn't have any codes / check engine light, but I pulled the throttle position sensor out while it was running, and it didn't change how it idled. I was surprised. Thought it wouldn't run without it. Plugged it back in, turned the truck off and now when I restarted it I have a check engine light and a code P0123 / TPS something or another.
I'm wondering if I might not have a PCM going out? I have the voltage drain happening. The cruise control not setting. The TPS sensor thing. Am I nuts or is that a possibility?
