Hesitation/fuel delivery diagnosis...

[tdc_worm]

Symptom: sluggish acceleration under all conditions (including fulll throttle). Wide open throttle speed is normal

Conditions: fuel did sit for 2 months over the winter w/o stablization. Have replaced run over 150 gals of fuel thru tank (from the same source I fuel my other vehicles). Have changed the FCC filter PN# 082026. My boat does not appear to have a primary fuel filter inline PN# 080024. In it's absence that leaves the low pressure rule pump, the high pressure fuel pump, the injectors as my problem. Possible the TPS? Thoughts?

TPS should throw a code.

TPS should throw a code.

Suppose that means a trip to the dealer to hook it up to a computer for diagnosis?

Can't you scroll through the warning codes on the dash? Check your manual to see if TPS would show up. Some of the code descriptions show on the dash pod.
