[s-cars] Cranking problems...

[Jerry Scott]

I had a similar starting problem a while back.  I put a fuel pressure 
gauge on the fuel rail and found that when it would not start, I did not 
have pressure at the rail. It would take a lot of cranking to get the 
fuel pressure up to 58 psi..  I ran a can of B&G 44K through the tank 
which so far has cured the problem.  My guess is that the check valve at 
the fuel pump (in the tank), or the fuel pressure regulator, (FPR) on 
the fuel rail, has gummed-up and now allows the fuel to drain back to 
the tank after the car sits for a while. When you go to start, the fuel 
line has to fill before it will fire. Try the B&G for about $20 before 
replacing the FRP or the fuel pump.
