I have a 1997 chevy 5.7 z71 k1500 pu. i have starting problems!\r\nproblem: i turn the key allowing the fule pump to get pressur up then start. i get the starter turnning over fast like its working but getting no gas for about a 3 count then its draging like a dead battery or a bad ground. id doesnt always happen but more often when its damp out. can happen when its been sitting for a while or after its been driven. i have replaced: fule filter X2, fule pump (pressure id good), crank, knock, o2 x3, sensors ignition modual, full tune up. battery x2, starter x8+, alt. x4. all the battery cables (2 starter n fuze block under hood) ground cables ALL1 even added a few heavy duty new ones. i love my old truck and she still looks great but she is getting as dependable as my ex-wife and mother in law. some one help!!!

SOURCE: hard start

Its your fuel pump.I had the same plomblem not too long ago.I was spraying either in to start it.I have a 97 chevy truck witch requires 65 psi to start and 55 to run properly.You need to find out much psi you need to start it.You can probaly look in your manual or just make a few calls.My truck had 55 psi and it ran fine i just had to get it running first.Good luck.I wonder if that fuel pressure regulator was a waste of time like it was for me.

try messing with the radiator because it is most likely overheating

That eliminates the crankshaft and camshaft position sensors. Have you checked the fuel injector itself for an open winding or stuck valve plunger? There should not be a steady 12 volts to the injector--if good injector, it would be spraying fuel steadily into the throttle body. But at least the engine should try to run if poorly. Take the injector out, dry it off with air, and intermittently apply 12 volts to one terminal while grounding the other. You should hear a click from inside every time you touch 12 volts. If not, replace it. If it does, it may be plugged with debris. Try blowing through it in reverse with compressed air.

Check the fuel line it may have a small hole that is allowing air in. If air is getting into the line the fuel will flow back into the tank. Happend to me one day and it turned out to be the clamp.

Been there before!!!! usually it turns out to be something really dumb that makes you say "Why didn't I look at that first???" (either while you are smacking yourself in the head , or, just after!!!!)
Good luck again!!!
