2012年11月26日 · The test is called "Bottle Test"-- here is some info--On the drivers side fuel rail-- to the back and next to the Turbo, you will see a "U" shaped 3/8 hose-- remove the hose from the fuel rail-- and plug the hose. Now attach a 3/8 hose to the fuel rail nipple, and stick the end in a bottle. Now drive the truck hard-- with several wide open runs ...

2024年9月13日 · The fuel injector return line pressure regulator (14) maintains fuel pressure on the return side of the fuel injectors. This is required for proper fuel injector operation. In the event the vehicle runs out of fuel, a check valve (11) in the exhaust after treatment fuel injector (10) supply line opens, and the fuel supply pump backfills the ...

2020年2月9日 · When the fuel pressure is low, the signal voltage is low. The fuel pressure regulator has a solenoid supply voltage circuit and a solenoid control circuit. The ECM controls the fuel pressure regulator, which regulates high pressure fuel that goes to the fuel injector rails and the injectors. Conditions for Running the DTC. The ignition is ON.

2024年10月6日 · The ECM regulates the admittance of fuel down to lower the pressure, so the more power applied, the lower the fuel pressure on the rails. Rock Auto has a good reputation for OEM parts, but I have not had problems with Amazon. I stick to Amazon seller parts only, not other sellers on Amazon.

2023年11月5日 · The fuel pressure sensor tells the ECM what the current pressure is, and the ECM attempts to control the FPR and thus the fuel pressure. However, since the FPR isn't plugged in, the fuel rail remains at full pressure. The FPR is a solenoid and when it has high voltage applied, it restricts the available fuel to be pumped and the rail pressure ...

2023年11月25日 · The fuel pressure regulator 2 outlet volume test must be performed while the no start condition is present or incorrect diagnosis may occur. Engine cranking for 15 seconds. Observe the volume of fuel from fuel pressure regulator 2. The volume of …

2023年12月10日 · Replaced the fuel pressure regulator at the fuel rail (drivers side by the firewall) and haven’t had the code come back. Regulator was very sloppy compared to the new one and I’m sure the fuel was bypassing the o ring. Just wanted to update everyone. You have to get the fuel rail and regulator as GM won’t sell just the regulator.

2023年11月21日 · 6. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 3 and ground. If less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance. If all circuits test normal, replace the ECM.
