Re: [DML] Re: Warm Start Issue -- Looking Elsewhere Than Fuel System (David McKeen)

[Marc Levy <malevy_nj@xxxxxxxxx>]

I'd look at the connectors on the big ignition
resistor on the firewall.  Also check the connectors
right at the coil.

It may also be helpful to carry a timing light with
you.  Next time it does not start, see if you have
spark (using the light).

It is possible that a problem in the ignition
electronics are not activating the fuel pump relay.. 
Once you try it a few times something may change in
the system that give you enough power to get a good
spark... and keep the pump relay closed.

OR..(shameless plug)  come to the DMA Spring social on
April 26, and have a few more people check it out in
person!
