Long crank when HOT only
 

'94 3.2L has a long crank, but only when HOT. Always cranks and starts fine in morning or after work. Has never NOT started, but takes an excessively long time once warmed-up. No "Check Engine Light" or DTC's. Was thinking a cam or crank sensor, but temp shouldn't effect those...

Ideas welcomed!

This happened on a non Isuzu vehicle of mine. The fuel pump relay was old, weak and would stick when warm. A $5 fix. Can you hear the pump when you turn the key to "on" w/o starting it?

Just checked "Cold" and could definitely hear the pump. Will check tomorrow after diving when it's HOT. Thanks for the suggestion... will post update soon!
