Engine/Transmission (1998.5 - 2002) Help. Hard start problem.

[clw1100]

This started yesterday after I filled up a Flying J. Truck starts fine cold. 1 to 1 1/2 engince cycles and it fires right up. But, after the truck gets to normal operating temps and I have to restart, it takes maybe 5 to 7 engine cycles to fire up. I thought it may be losing prime somewhere so I tightened everything I could find on the supply side. Even after I start the truck (after the 5 to 7 engine cycles), IF I shut it down within 30 seconds or so and restart it as a test, it still will still take 3 to 5 cycles to restart. Restarts after several minutes of engine running are fine, unless I let it sit for about 7 to 10 minutes. Yet if I let the engine totally cool for 2 + hrs it will start fine.



HELP TDR Brotherin!!!!

Hard starting when warm is often an indicator of a dying VP. Any codes? Beware of P0216!



Mine is hard to start also, but totally different than yours. Mine is only hard to start when it's been sitting a long time. I am getting air in the system somehow.



what is your fuel pressure??

Pressure has been a constant 15+ psi (FASS). The truck runs fine if not great otherwise. I tested on the way home and it will hit 3200 + rpm on fast takeoffs and passing (if that makes any difference. ) I put on the FASS about 8K miles ago in December. This is a 1 year old VP put on back in January, 2003.



Thanks for any help.

Also, no check engine light. I am going to autozone tomorrow to hopefully get a code scan

[jerrethomas]

keep us updated on the situation. this isn't good if the vp44 is going that quick from when you had it replaced last year.

Back to the top.



Any good news on the hard to start condition?

Are you using the factory wire to supply power to your FASS system?
