Hot Start Problem

["Brian Haygood" <Scirious@hotmail.com>]

 I searched the archives, and I'm wondering whether a hot start relay will
help this problem.  It's an '87 16v.  I've followed Bentley's checks for the
cold start injector and rest position of the air flow plate.  Once started
the car always runs well and strongly.

 My car's ability to start varies with temperature.  On colder days (70's or
so) it fires on the first turn or two.  When it's around the mid 80's it
takes a several turns for a cold engine to fire.  If I drive the car around
a while (up to operating temps) on a warm day, and try to restart it within
about 5 minutes, it will start very reluctantly.  If I let it heat soak for
30 minutes or so, it will turn over forever and never fire, though
occaisionally it will sputter on the first crank or two.

 I have tried push starting it twice and both times it started right up,
though the cranking speed of the engine seems pretty good, and I can crank
it for quite a while (10 seconds) without it slowing down.

 So it sounds to me like something in their doesn't like being heat soaked.
The archives mention that putting a hot start relay in the ignition
somewhere fixes a heat soak problem, but it sounded to me like this was a
fix for cars that refused to turn over.  Mine turns over pretty well in any
condition.

 I don't believe this is a fuel accumulator problem because it relates more
strongly to temperature than to time.  If the car is allowed to cool it
starts well.  I have not checked the screw on the back of the accumulator
for leaks, yet.

 If anyone can verify that I need a hot start relay, could you also tell me
where to get the relay, where it wires in, etc.  Also, would this same
problem disappear if I just replaced some wiring and didn't put in a relay?
 Thanks for your help, listers.

 Sincerely;
 Brian Haygood
