[DML] Re: hotstart problems

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

Do the plug change thing with the CPR. If it starts up then it is a
fuel problem. If it still won't start you may have a bad pick-up coil
in the distributer. Vapor lock is not usually a problem on a fuel
injected car where the fuel is under high pressure. There ARE other
causes for the rest pressure to not stay up but the usual culprit IS
the fuel accumulater. The other things could be a bad pick-up hose in
the fuel tank so there is air in the fuel system, a leaky check valve
on the fuel pump, or a leaky pressure regulator on the mixture unit.
Of course if there are any fuel leaks they can also drop the rest
pressure. You have to narrow down if it is fuel or electrical first.
