Correct Chuzz. No distributor - it has an integrated electronic ignition system. Without knowing the fault codes it will be difficult to diagnose.Bob, I don't think there's a distributor in the 03 3.3 liter engine. At least, there's not one in my 99 GC with the same engine. Your friend needs to look over the repair list very closely. Maybe he's also go the infamous instrument cluster failure.
Aside from possible a bad instrument cluster, I'm puzzled. Possibly a fuel issue?
Bob - what repair expenses have totalled $1500? Seems like an awful high price for what has been replaced.
