[DML] Re: hotstart problems

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

If you keep insisting that the problem is vapor lock you will not look
to where the problem really exists. Heat soak IS a problem but not
relating to fuel. It seems to cause a bad pick-up coil in the
distributer to act up. The next time the motor is hot and won't start
check for spark. If you don't have any it is "probably" the pick-up
coil. If you DO have spark try the plug swap. If THAT works then you
DO have a fuel system problem, maybe you aren't holding up the rest
pressure like you think. The rest pressure "in theory" is supposed to
prevent vapor lock by keeping the fuel under so much pressure it can't
boil. The fuel also gets recirculated by the fuel pump so it doesn't
get so hot when the system is running. Maybe you have a bad suction
hose in the tank and the pump is getting air. That can cause the
symptoms you are experiencing too. Deloreans in general do not usually
have a problem with vapor lock unless there is something wrong.
Installing shrouds may get rid of the symptoms but you are not
correcting the underlying problem.

even when the proper rest pressure is maintained the problem still
exsists .So you can go by the book all day long and quote specs till
your blue in the face but dont cry to me when you get stranded
somewhere.Heat soak is a constant problem with Deloreans and Fiats.I
have installed cooling shrouds on several cars with excellent
results.I also point out that ford uses fuel injector cooling shrouds
on several of its vehicles.
