EFI starting problems (was-still is : Fuel line check valve)

["Rob P" <fristpenny@xxxxxxxxxxx>]

Dick & list,

This is the same efi car you have been giving me advice on for the past 2 
months.  Autozone has the filters too.  The rear pump (an aftermarket 
external electric we have already discussed) is turning on to purge, usually 
just a quick buzz, occasionally running for a few seconds.  I haven't been 
able to verify that the front one is.  It's still not enough, so I'd like to 
replace the check valves.  Somebody here must have replaced them.  Without 
the check valves the purge cycle isn't always enough, I had the same problem 
on an '03 which was replaced under warranty.

The car has other issues which contribute to the difficult/indefinite 
starting, but I am tackling them one at a time.

Rob
