Hey guys,
Hoping someone may have a few suggestions on where to start troubleshooting an issue on a 1.7 litre diesel cummings made by isuzu in a 2008 Campion. It is a friends boat and he has sunk a lot of money trying to rectify this issue to no avail. I'm going to have a look at it tomorrow and do have some experience with diesels but not an expert. Basically the way he describes it is it runs fine at idle and up to 2200 RPM but will not go any higher, it previously ran upwards 4200 RPM.
So far he has checked the mechanical linkage, fuel supply (filters etc.) and had the fuel pump rebuilt to the tune of $2,000.
He says no black smoke when trying to apply throttle.
Anyways, if anyone has any info or tips on where to start troubleshooting this problem it would be much appreciated. Thanks in advance for any advice!
