Hey
I am new here. New to anything Ram actually but did own an 08' Wrangler so familiar with Chrysler products.

New to me 2008 Ram 1500 5.7 Hemi 4x4
Just swapped the spark plugs and boots for NGK V power (OEM Equivalent).

Truck turns over about 6 or 7 times before finally firing and comes to life in limp mode. Throws p0335 - crankshaft sensor code but my intuition is that the crap ignition conditions are setting off the crankshaft sensor causing a red herring.

Disco'd the battery over night and hooked it back up.
Fired up perfectly and ran perfect for about 60 seconds...then died and (see above) further cranks were hard-starting and resulted in limp mode.

Items I touched/replaced to cover my bases for you:
-throttle body was removed and thoroughly cleaned.
-spark plugs replaced (I did 2 new sets the day before last because I wanted to confirm I had good spark...1st set were DENSO)
-spark plug boots
-coil packs cleaned up
-water pump replaced
-coolant swapped
-new serp belt
-new thermostat
-new oil
-new air filter

Do you have the proper way to clear the TIPM/computers in this thing?
Any thoughts/suggestions?

Thanks in advance
