Stops cranking while cranking.

:boggled: Say What? Yes, It stops cranking while I am trying to start it. Key it again and it spins over fine and starts. Done this twice so far this month. Like the starter quit mid crank or you let the key off before the engine starts. Pretty sure I had the key solid in the start position the first time. (You know the early GM warning before you walk sort of issue?)

Would this be a loose tone ring TSB for the CPS? It always kinda idles funny like it has a miss when first starting, but, isn't missing.

Then again all my stuff is kinda funny.

05 LLY in the LLY section... :hihi:

Could be a problem with the cam tone ring. That isn't to uncommon for an LLY. Pretty sure the LLY triggers the starter via the ECM, so there has to be some reason why the ECM would stop or over ride the starter.

You need to sell that thing so Im not confused when you post

Figure it out?
Don't know if this helps, but you cannot crank the starter if the engine is running with your truck right? My old 03 Dmax wouldint let me. Anyway maybe your ecm thinks the truck has started allready so cuts the starter out??

That's what I was thinking. Like there's a shorted wire somewhere.
