My 1988 k5 blazer wont start untill i pour gas in to the tbi. when you pour gas in the tb i it will start and run fine but when you turn it off it wont start untill i pour more gas in . Does anyone know what is wrong.

 

check your fuel pressure at the fuel rail, this is a very common problem for those of us with the s10 blazers, the fuel pump starts to go and no longer provides sufficient pressure to run the engine while the starter motor is still engaged.
