50 to 60 psi . 55 being ideal . 96 to 99 are known for fuel preassure regulators going bad as well as the fuel pumps. if you ever have a fuel pump go out buy the new pump assembly dont short cut and just buy the pump. ASE tech, Bill
Check fuel pressure, fuel pressure regulator.
Possible bad fuel pump, fuel pressure regulator. Give more symptoms
It is built into the alternator, You will have to replace the alternator.
Damper? I assuming you are talking about the regulator it is usually on the upper intake connected to the fuel injector assembly.
I think the fuel pump is the regulator on fuel injected engines. The FPR is located on the driver's side of the engine, it has a vacuum hose going to it and is held on with a spring clamp similar to AC connector clamp. On most 1996 Chevy Tahoes the fuel pressure regulator is actually inside the intake manifold. You must remove the intake manifold to replace it.
The oil pressure switch on a 1997 Chevy Tahoe is located on the back of the engine. It is in the center-rear part of the engine.
On a 98 Chevy Tahoe, the transmission fluid pressure switch is located on the valve body. It is found to the right of the engine.
The oil pressure gauge will fluctuate on a Chevy Tahoe when the vehicle is idling and when the vehicle is driven at highway speed. Idle is usually 30 psi oil pressure or slightly more. At highway speed, the oil pressure should be between 60 psi and 80 psi.
One of the causes for low oil pressure in a Chevy Tahoe could be a clogged or dirty oil filter. Changing the filter may get rid of the problem.
The voltage regulator in the alternator is probley weak. Replace the alternator
Low fuel pressure.
60~66 PSI
