    fuel delivery question 4.3 tbi

    my 89s fuel pump went bad last year. replaced it and ran for awhile like normal and now it wont start up. the last time i tryed to start it it fired and would just die when i gave it gas. i figured maybe the gas was old so i added 2/3 gallons tryed again and got nothing. got another 3 gallons today added to the tank. this time i poured a little over the butterflys and she cranked over. i pulled the throttle cable and saw a few drops come out the injectors i though the fuel looked darker then the fresh gas. but it just may have been the light in the garage. im not sure so im thinking im gonna try the fuel filter first before i move to the injectors or regulator. any thoughts on where it could be bad?? injectors vs regulator vs fuel filter. i got get the truck moved to my new place.

    Had the same problem with my 86 with a pump that was only a few years old. Come to find out the problem was with the junk gas they are selling now it had already started breaking down the rubber hose between the pump and sending line. It had swelled twice the size of normal and had split down the side. Replaced it with some braided line I had and the problem was fixed. Ethanol is the worse thing they could have ever done adding to gas.

    Did you replace the fuel filter yet? If not I suggest that first. If you want I can pull some used injectors &/or regulator from the boneyard. I go 1-2 times a week.
