Instruction on replacing a fuel regulator in a 1198 chev pickup

are you asking where is the fuel pressure regulator , or what regulates the gas/throttle ?

the fuel pressure regulator is on the end of the fuel injector rail (fuel hose connects to it ) caution HIGh fuel pressure there even with key off

on a 02 there still is a throttle cable that connects throttle body to gas pedal todays model doesn't have that anymore ,it s all wires now

Bad fuel pump?

You don't---------- It is broken

Remove the door panel & get all broken items out

Broken Window Regulator has to be replaced

check your fuel regulator

under the intake manifold between the fuel rails to replace you need to remove atleast one of the fuel rails to spread them apart for the regulator its not a very hard thing to do just be careful with removing the intake

The fuel pressure regulator. its on the end of the fuel rail. pull the vacuum hose off the regulator and look inside. If the inside of the hose is wet with fuel, the regulator is bad.

check your fuel pressure regulator. its on your fuel rail. after you have had it runningpull the vacum line off of the fuel pressure reg and if you see fuel there its bad and needs to get changed and that being bad will cause a hard starting problem

Ck your fuel pressure regulator. pull of the vac hose at the regulator, if it has fuel in the line, the fuel pressure regulator will need replacement.

Double check all freeze plugs they have been known to cause funky problems, that also could be the fuel pressure regulator malfuctioning...
