Will low fuel pressure cause misfire?

Low fuel pressure in the fuel system will cause a faulty air-fuel mixture and then, in return, cause weak combustion. This can be felt as misfires on acceleration or even at idle.

How does a TBI fuel pressure regulator work?

The TBI unit, regulator, and return fuel line need to pass back to the tank any fuel that isn’t used by the engine. … This vacuum referenced fuel pressure regulator (VRFPR) changes the fuel pressure as the engine load changes. A higher engine load equates to a higher fuel pressure along with a higher injector flow rate.
