1994 Chevy Blazer i think it may be a

i replaced fuel pump , thottle pos. sensor, my asselorator wire was shrating apart i bought that.

Now after fuel pump was replaced it drove but i have recently dropped the tank again i seen that it squirest out of the pump so maybe i have that narrowed down !?

when i done that the blazer would crank but , when you drove away it would die out then leave me stuck.

Now i been buying parts and it isnt helping.
Some one is telling me fuel pressure regulator,where is that located.
If not, what do you think the problem is??
