The PCM (Powertrain Control Module) controls the ground to the fuel pump relay.
Most fuel pumps operate on 12-14.2 Volts. (system voltage). Keep in mind that most fuel pumps operate off a relay and the relay is turned on and off by the engine computer. Most computer control the GROUND circuit of the relay to power it on and off. It is fairly common to have to replace the fuel pump in the tank as the brushes wear out after about 100,000 miles
Bad ground.
No it will not. Those 2 engines have a total different type of fuel system and sensors.
the first thing to check would be the alternator/voltage regulator
yes it dose it controls the voltage to the fuel pump and therefor the pressure
On a fuel injected truck it is a part of the computer behind the battery.On a fuel injected truck it is a part of the computer behind the battery.
12 volts
No, a Chrysler Cirrus does not. The fuel system is computer controlled with relays.
voltage spike, bad computer, dirt/grit in fuel line plugging injector,
Check your battery voltage, low voltage will not allow electronic fuel injection to work properly. Fuel? Spark? Compression
The oxygen sensor measures the amount of or lack of oxygen in the burnt exhaust exiting the engine in the exhaust pipe. It will then send a voltage signal to the vehicle computer. The computer uses that signal to control the fuel metering coming into the engine to try and keep the air/fuel ratio at 14.7 parts air to 1 part fuel. This is for emissions and economy reasons.
In order of probablility: fuel filter, fuel pump fuse, fuel pump, fuel pump relay, control system.
