i have a 93 tbi 4.3, im looking for the location of the fuel pump relay,
i think its under that black cover on the firewall, but im unsure,
(havn't really looked to tell u the true)

i know their is the back up unit(oil sending unit) thats located at the back of the block

As far as I know the fuel pump relay is on the firewall where you think it is.

I do not know of a back up unit though :think: I'm pretty sure the oil pressure sensor/sender is on the back of the bock near the distributor. I had it apart, its got oil on it and its got wires coming out of it, dunno what else it would be :crazy:

yeha im gonna pull the cover off on mine tomorrow,
the problem i have is that i think after alittle bit of driving, say like
30mins or so, the truck will just turn-off, and wont turn on for about 10mins or so
i checked the fuel pressure and it was 13psi, i havn't checked the fuel pressure when it turns off like that tho

its not my daily driver anymore, i drive it to work maybe 1 or 2 times a week now, and i want to drive it to a show thats about 45mins away so i need to get this problem fixed or im gonna have to use one of my bosses trailers and tow it to the show with my nbs but i don't really want to do that because thats kind of ghetto
and i don't want to be rolling it down the highway and have to pull over for about 10mins or so for this thing to cold down and start up again
