Where is the fuel filter on a 1991 corvette? - 1991 Chevrolet Corvette

The fuel pump relay in the 1991 corvette is located under the IP on the pass side.
Open pass door, unscrew two screws under the glovebox take off the fuse panel, unscrew third screw to plastic plate underneath glovebox, pull away carpet , pull down plastic plate under the glovebox you will find a number of fuses and relays if you reach in under there-their in a row, one in the middle is the fuel relay, and they are the same https://www.google.com/search?q=1991+corvette+fuel+pump+relay+location&rlz=1C1CHBF_enUS812US812&tbm=isch&source=iu&ictx=1&fir=22ZCtfxXLAJIhM%253A%252CT6ISkStpACZ3fM%252C_&vet=1&usg=AI4_-kQcWSXh1X3gyHRgNaeIT01QKiHSbQ&sa=X&ved=2ahUKEwi72ajMpdviAhUCZN8KHRgdBRQQ9QEwAHoECAUQBA#imgrc=22ZCtfxXLAJIhM: https://www.google.com/search?q=1991+corvette+fuel+pump+relay+location&rlz=1C1CHBF_enUS812US812&tbm=isch&source=iu&ictx=1&fir=22ZCtfxXLAJIhM%253A%252CT6ISkStpACZ3fM%252C_&vet=1&usg=AI4_-kQcWSXh1X3gyHRgNaeIT01QKiHSbQ&sa=X&ved=2ahUKEwi72ajMpdviAhUCZN8KHRgdBRQQ9QEwAHoECAUQBA#imgrc=zm66sLFTaleu2M:&vet=

sound like vacuum leak check replace all old vacuum hoses replace pcv make sure its getting vacuum.make sure spark plugs and wires been replaced.replace fuel filter and air filter clean fuel injectors.code scan for faulty idle air control valve.but do a little tune up see if that helps.most time if i have problems with vechicle i do a tune up make sure engine getting good airflow.plenty of fuel and good spark.i will do a three stage trouble shooting before i find something major wrong with engine.

FUEL RAIL TO INTAKE BOLTS TORQUE IS 15 - 22 FT LBS.

The pump should run for 10 seconds then stop if the computer does not see engine rpms. I said check the regulator for leakage, not replace it.

39 pounds is not enough. Make sure the regulator is good, check for injector resistance

It sounds to me as though you have a clogged or malfunctioning fuel pump. Depending on the engine in your car, and whether or not the engine has a carb or fuel injection system.

In most of the early 90's corvette's, there should still be a fuel filter on the fuel injection throttle body (it looks like a carb), and a fuel filter under the car on the fuel lines. I believe you'll want to check the passenger side, but follow the fuel lines to find the filter. You might only have one under the car, so don't be alarmed if you don't find a small one on the throttle body.

Try changing your fuel filters first, as this is an inexpensive way to make sure your vette is in optimum condition before you do anything else.

If fuel filter replacement doesn't work, you will want to have your fuel pump tested. The only way to DIY, is to remove the fuel pump from the lower drivers side of the engine and to blow in the "in" side with a little water and see if it puts out the fluid. Even at that it could still be bad, so if you pull the pump, plan on replacing it.

The only other realistic option is that your fuel injectors are dirty or the gaskets are bad and it is time for an injector overhaul. This is not to hard to DIY, but does take patience and attention. You can also try running some fuel injection cleaner through your engine before trying anything else to see if it helps.

Some unlikely options are that your smog pump is clogged, your catalytic converter might be bad, you EGR valve or Purge Valve is clogged, your timing is off and you need to check the spark system, or that you could have low compression.

If there is not fuel going thru Fuel injectors, then it won't start. You can buy NOID lights at any auto store to connect to Fuel injectors to see if there is a problem with Fuel injector module. Here how the NOID lights look like:

You plug these into the connectors of Fuel Injectors to check during cranking. If there is light then your Fuel iinjectore Module is Good.
Then there is a problem with the Regulator. Here how it look like.

Open pass door, unscrew two screws under the glovebox (you will be upside down in the car), take off the fuse panel, unscrew third screw to plastic plate underneath glovebox, pull away carpet (velcro), pull down plastic plate (watch out for the wiring to the lamp), then under the glovebox you will find a number of fuses and relays if you dive in under there DEEP, prob 4 or 5 in a row, not really sure wich one, but one in the middle is the fuel relay, and they are the same (interchangable).
Take a look at --the12volt.com/relays/relays.asp--
It´s those relays we are talking about.

could be vapor locking, losen up the fuel cap and see if that helps if so then replace it!!!!!!
and chane the fuel filter also

did u change fuel pump relay its common for them to act up especially with the high temp under that hood
