SOURCE: Where is the fuel regulator located on a 1988 tbi

No, low fuel pressure is caused by a weak fuel pump.
High fuel pressure is caused by a faulty fuel regulator.

Make sure you are getting power to the injectors. I have the same,350 tbi. Check the fuses and relays and check the wires at the tbi to make sure one of them is not rubbed through. The injectors have to be getting intermitent power .

Sounds like the fuel pump is going bad(or in this case,has gone bad). I suggest that you change the fuel pump and use a fuel cleaner in your gas tank as dirty gas may have caused the problem to begin with.

You have TBI, check the two injectors for a "V" or cone style, spray pattern. There shouldn't be any dripping. Also check the TBI assembly for any leaks. The fuel pressure regulator is mount at the rear part f the TBI. If the diaphram is damaged it could cause exsesive fuel to dump into the engine.
