    I have a 99 s10 with a 2.2L. I jus recently replaced the fuel pump and fuel pressure regulater. In the morning Ican go out to my truck and it start on the first time. I cn get to work let my truck sit a while and if i go back out and try and start it i have to let it prime 2-3 times and turn over for atleast 15+ seconds. if i hook the pressure gauge to it and turn the key on engine off it will rise to spec. but immeditly start to drop till there is no pressure at all anymore. Any suggestions or help pleasee it would help out great!
