I had a 94 S10-SS and i had to have
the original pump replaced at bout
15.XXX Miles then i had to have that
one replaced tooo........! all before
36.XXX miles...........! the day that i
had the original pump go out...i was
told by a guy.....that his father had
a 94 S-10 with the L35 and his had
gone out at bout 15.XXX mile point
So problems with the fuel pump is a pain
but nothing new..........!
I just installed a new fuel pump last fall, which is the second one for this truck so far. They're electric and mechanical, so that's two reasons to fail. I managed to get around 40,000 mi out of the last one, so I don't complain. My only fuel system trouble is the intermittent sending unit. It works when it wants to.
With Fuel pumps on the 4.3's you will waste your money replacing fuelpumps unless you replace the sending unit aswell.
Dont ask me why but i went through 4 fuel pumps... then changed the fuel pump and sending unit again and havent had a problem since... that was about 9 months ago
YUP!!!$325...that's from a dealer with a 10% discount, but you might want to check like Pep Boys or O'riley's and places like that cause they can often times sell you the same AC Delco part cheaper than the dealer can buy it!!!
