hard starts

[Jarrod B]

so i have been having hard starts more often now. i can let the truck idle for a few mins and shut it off. the next crank takes a few secs longer than normal to fire up. someone told me it could be the ipr going out. b4 i spend $$$ i just want to know if that was the issue or its something else. oil has been changed and is full (with 15qts) and has a new fuel filter. plus the napa air filter isnt dirty...yet. just a grey tint on the white paper.


so what can it be?

If you don't have access to good scanning tool that can read the pressure for you then you could make an oil pressure reading tool for about $60 at any good hydraulics store. Get one with hose rated to over 3000 lbs working (about 12,000 burst). Or, for a little bit more, there is a guy on ebay that has brand new IPRs for under about $85. Also, check that your ICP is working correctly (see if there is any oil in the top of it).
