The Chevy Corvette began Industry in 1953. Its fuel delivery course revolves enclosing the fuel pump. The Corvette ZR1 has the imitation's most Strong engine, an LS9, Eaton supercharged 6.2 litre engine that produces 638 hp and 604 foot-pounds energy of torque. Evaluation the fuel delivery manner whether the Chevy Corvette runs Rugged, hesitates or cuts away while driving.
Instructions
1. Proceeds fuel course impulse by disconnecting the dissension battery cable and loosening the fuel fill cap. Remove the embrace from the left fuel against and cover a towel over the fuel impulse valve becoming on the rear passenger side of the fuel lambaste meeting. This protects you from any pressurized fuel spray. Remove the fuel coercion elimination Harbour cap and attach a female Schrader valve coupling from a fuel impulse inspection gauge.
2. Reconnect the battery cable. Inquire a helper to turn the ignition material to the early position for 20 seconds, however arrange not open the vehivle. After 20 seconds, turn the ignition off and visually research for leaks. Provided there are no leaks, hang in with the fuel delivery diagnostic.
3. Remove the vacuum limit from the fuel pump force regulator and analysis for fuel. Consult to the owner's book for the column's end whether you aren't undeniable where it is.6. Inspect the fuel filter for clogs if the Corvette still experiences fuel delivery problems after you adjust the fuel pressure. The fuel filter on 2003 Corvettes with feedback fuel systems, and on 2004 through 2005 Corvette models is located in the fuel sender assembly inside the left fuel tank. To remove and check the fuel filter, drain the fuel and remove the fuel tank, so consult a professional for any further fuel deliver diagnostics.
4. Start the engine and let it idle as you remove the vacuum line again. Watch the pressure gauge. Fuel pressure needs to read between 47 and 48 psi. Stock pressure for 1985 through 1987 Corvette models is 36 to 39 psi. For models made in 1988 and later, 40 to 42 psi is required. Increase the pressure by turning the regulator adjusting nut clockwise.
5. Leave the engine on and watch the pressure gauge as a helper works the throttle. The gauge needs to register approximately 5 psi. If the reading decreases, the fuel pump is malfunctioning or the fuel filter is clogged. Turn the engine off and remove the pressure gauge.
There shouldn't be any fuel in the string. If there is, the engine problems are likely caused by a faulty fuel pump pressure regulator, which means the fuel is flowing back into the lines instead of into the engine and so there is not enough fuel in the engine. If there is no fuel in the lines, reattach the vacuum line and continue with the fuel delivery diagnostic.
