Steve - what is the fault related to?
It's obv a transplant, so i can see a major botch on the cards.
Vacume pipe around the back of the inlet gives problems with leaks.
If the engines worn, it won't like hot starts. Again, maybe a reason why the fuel pressure may have been increased. The ex gf's car had really worn bores, and that was a bastard to start. They just dont create enough vacume.
Rick.
