New symptom

[Jay Kempf]

This morning thinking I am on the track to determine a bad pump check 
valve I started cracking the first banjo bolt on the fuel rail to go 
after the fuel pressure regulator just to see if I can get my gauges on 
those buried connections. When I cracked the fitting before even trying 
to start the car I got a hiss of pressurized fuel. So that means it held 
pressure overnight. So I tried to start it and it hydrolocked. Hmmmmm? 
So I pulled plugs to see what the heck. Seems a bunch of fuel smell on 
the plugs. So after I got them out I defeated the ignition and turned it 
over to clear whatever it was. Only number five had fuel around the plug 
hole so that's interesting. If a single injector leaked that bad 
overnight then how could I have pressure and if I have pressure in the 
rail overnight then how can the FPR or the Check Valve be faulty if they 
both stayed closed overnight? It did not want to start and I am assuming 
that is because it was so rich it just had to clear itself for a bit. 
Then it ran and started normally. I have another set of injectors. Still 
blind on the pressures until I can get the gauge hooked up.

If the FPR is stuck shut and not responding to boost or vacuum would 
that overpressurize the rail to pump pressure (like 8 bar or whatever 
dead heading the pump will do?) Need to borrow or buy a gauge or adapter 
set or find the right adapters at least.
