Question about 1999 Chevrolet C/K 2500
My 1998 chevy tahoe with 5.7 Liter, 4X4 Automatic is hard to start when the motor is cold, runs good & starts ok when it is warmed up. Acts like it may be flooded. I've replaced the fuel pressure regulator & fuel filter. The fuel pump has been replaced about 16 months ago (twice). There isn't any fuel pressure in the lines after it sits for a short time, where is the fuel pressure draining to? Thought it might be the check vavle in the fuel pump, or the seals in the fuel injection module. I have a 5.7 liter Vortec and takes two maybe three cranks to start. After warm starts every time. I have recently replace fuel pressure regulator and did not help. Any advise, thanks
Replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.
