When I try to start my truck it takes anywhere between 10-30 seconds for it to actually start. Then, if I'm not careful, it stalls out and I have to start it again. I then can use it all day and it starts and runs fine. It's only after I let it sit for 8-10 hours that it has problems starting. My first thought was bad fuel pump and with no real way to check it without dropping the tank I just bought a new fuel pump (figured I might as well). That did not fix the problem. I checked my injector and it SEEMS fine, but I'm only the nephew of a mechanic and have very little know how. I'm looking for other options as to what might be my issue.

had the same problem with an 98 s10 blazer turned out to be the fuel pressure regulator. It would lose it's prime and cause piss poor start up especially in cold weather. Don't know if that's your problem but its probably similar.
