My dads early 04, 305/555 is now experiencing a hot start issue. As in, it wont restart hot. When it is cold it seems to crank longer than necessary, but always fires up. We replaced the FAC already on the injection pump.

Starting to think its the injectors, truck has 90K miles and had the pump update done by the dealer, under warranty.

Any thoughts? I have browsed a number of forums and no one seems to have a good answer.




One thing you might check is the nuts that hold the crossover tubes in the head. If they are not torqued properly they can cause a pressure leak and cause the symptoms you are describing.
