Re: 1992 Chevy Suburban starts but wont run! Was running fine.

when i first read your post, i thought fuel pump....

(but you said you just replaced it, wish gm made it easier to check fuel pressure on the tbi's)

what brand of fuel pump did you use? was it an ac delco?

do you have any codes?

you might have to check the fuel pressure....


other than that i would check the coolant temp sensor on the intake manifold... search the user name chevy tech on here, he has posted the ohm vs temp values for that a few times....
