Hey Mike, I've heard this problem a lot of times on the DML, I believe the "quick fix" solution to this is to switch the blue plug connected to the cold start valve with the black plug on the ....i forget the name of it that is right near it in the engine compartment this will force gas into the engine and make it start. You are having a "hot start" problem. And I remember hearing from DMC Joe that the "correct" solution to this is to replace the Fuel Accumulator, am I right? DMCJoe? Thanks a lot, Nick VIN#1852....complete tear-down and rebuild DeLorean now...wish me luck!
