[s-cars] Almost No-start question

[calvinlc at earthlink.net]

I agree to start with the FPR.  Really you should put a fuel pressure gauge
on it and watch it after the car is shut off.  If you don't have a gauge let
the car sit over night and the next morning crack one of the banjo fittings
in the fuel line.  If it doesn't have much pressure behind it then it is
most likely your fuel pump check valve for FPR.  FPR is cheaper and faster
to fix.  There is a way to isolate it but you need a "fancy" fuel pressure
gauge setup.  I had the same symptoms and had my pump replaced first - that
was dumb :)  because that wasn't it, turned out to be the FPR.

S-heads,

Thanks for the responses!  Sounds like the concensus is leaning toward
problems with the FPR, potentially leaky injectors, or fuel pump/check
valve issues.  I appreciate your kind assistance and advice!
