I have a 99 chevy blazer with a 4.3 vortec that wont start,so far i replaced the cap,rotor, fuel pump,spark plugs,fuel pressure regulator twice,crankshaft sensor,fuel meter body,and all 6 injectors.I verified that i have spark and fuel,but fuel pressure bleads off with the key in the on position as soon as the fuel pump quits running after the 2 seconds.I have pretty much given up on it and emptied my wallet,if anyone has any suggestions please let me know thanks Chad

in the distributor ther is module it runs the fuel before that change the relay for the fuel pump it,s in the glove box read the book it tells ya were it is
