Your 1990 chevy has TBI fuel injection, open the hood, your air filter sits right on top of the motor (easy to spot), take the air filter completely off ( the housing & everything). next you should see two fuel injectors, they are attached to the TBI unit, (this is called the throttle body), if you look at the screws that hold the housing together on top there should be 8, if your standing facing the truck head on the fuel pressure regulator is inside of the housing directly behind the fuel injectors, if you take off those 8 little bolts, you'll get to it ( but make sure & be carefull, this is kind of a hasel to change, those 8 bolts have to be torqued to specification, something like 13 inch pounds, pick up a haynes manual, those specs should be in there.

where is the transmission censor located on a 1997 Chevy cheyenne truck
possibly a fuel regulator or bad valve
Pump regulator is located inside the gas tank and is an integral part of the sending unit, pump and emisssion valves (two of them).. The other (depending on what engine your truck has) is located on the inlet side of the fuel rail on top of the fuel injectors.
The fuel pressure regulator is part of the fuel pump module located inside the fuel tank. It is not serviceable. If it is faulty, the entire fuel pump module must be replaced either by removing the fuel tank, or removing the truck box for access.
If it is CFI, the fuel pressure regulator could be leaking fuel. If the check engine light is on, have the codes read.
It is bolted in the very top of the TBI housing behind the 2 injectors. The whole top of the housing will have to be replaced if the regulator is bad. It is all made together.
The pressure regulator is part of the assembly, that round thing on the top of it, where the fuel line connects. YouÊneed to crawl under the truck to take a look, if there is a fuel leak it would smell all the time.
if you have throtle body injection the regulator should be right on the throttle body it self.On a 1996 Chevy truck there is not a throttle body , the regulator is under the upper plenum(the plastic piece that sits on the intake)also the injectors are under there as well all 8 or 6 witch ever motor you have.
The fuel pressure regulator is located in the throttle body. More than likely you have a fuel pump issue. Those regulators rarely go bad.
YES BUT RUN A FUEL PRESSURE REGULATOR. YOU WILL ALSO HAVE TO HOT WIRE THE FUEL PUMP IF IT IS IN THE TANK.
