What should fuel pressure be while cranking?
the fuel pressure should not drop at all when cranking. the pump is junk if youre not getting a solid 55-65 psi. the cpi 4.3l engines require that high of pressure to run. multiport needs 40-47 psi, while tbi setups need only 12-17 psi.
Does cranking fuel pump run?
When you turn the key in the ignition forward to crank the car, the “start cycle” begins and fuel pump relay is engaged long enough to turn on the fuel pump. Once the engine is running, the fuel pump relay shuts off, and the current for the fuel pump is supplied by the oil pressure sending unit.
What will high fuel pressure cause?
Too high of pressure may result in, over fueling of the engine. As a result, this can lead to a rough running engine; poor fuel mileage, and black smoke coming from the exhaust. If your regulator is going bad, your car could display several different symptoms.
Can high fuel pressure damage injectors?
High fuel pressure results in a rich air-fuel ratio because the increase in pressure forces more fuel through the injectors than required producing increased emissions (HC’s) and black sooty exhaust. These excessive hydrocarbons overheat and damage the catalytic converter.
Can a fuel pump be bad even if it turns on?
Because fuel pumps constantly run whenever the ignition is turned on, they can eventually wear out and weaken over time. A weak fuel pump may still pump fuel, but the vehicle may experience difficulty starting from the lack of pressure.

What should the fuel line pressure be at full throttle?
• The fuel line pressure should be between 320 kPa and 380 kPa. • At full throttle the pressure should be steady at nominal value (380 kPa). • If pressure drops while throttle position is steady, then fuel starvation is occurring.
