100 psi
The fuel pressure is not adjustable on that vehicle.
45 to 60 lbs. at the Schrader valve on the fuel rail. Should be 50+ when driving. Easily tested with a Fuel Injection Pressure gauge set.
If it has a carburetor, 7 psi should work well.
check co adjust and if the eha is working, other then that fuel pressure regulator is probable suspect. eha is set to .4 bar by bosch and should not ever require adjustment, however they tend to bleed fuel internally and its best to just replace
There is no timing adjustment on fuel injected models the ignition timing is set by the ECU . Regards:
Could be that the air/fuel mixture is set too lean. Needs adjustment.
install a fuel pressure regulator and set it to 36 psi idle in a stock motor
Your air pressure should be set at around 42 psi. If you open the door there will be a sticker that shows exactly what the pressure should be.
You need to hook a fuel pressure gauge to it and adjust the regulator so that you have 9 to 13 LBS, of fuel pressure. No lower are higher.
To set the amount of fuel the engine gets at idle. It needs the right amount to run smoothly.
The fuel pump basically does what the name implies. It picks up fuel in the tank and pumps it from the fuel tank through a fuel filter to the engine. The pump is set to operate at a certain pressure that is needed for the application.
it is mounted to the fuel injector rail where the high pressure comes from fuel pump and pressure is at a set psi per engine there is also a vacuum hose that raises the fuel pressure about 8-10 psi when load is applied on motor to give a boost of power
