Cadillac DTS Fuel Pump
Hence the Fuel Pump of Cadillac DTS vehicles helps in supplying fuel to the engine within the optimal combustion chamber. It pumps fuel from the tank to the carburetor or the fuel injection mechanism; electric pumps are normally used in fuel injection. Fuel is supplied to carburetors by MECHANICAL PUMPS that are run by the CAMSHAFT. Performance fuel pumps are rated by flow in GPH or LPH depending on the requirement of horsepower of any particular vehicle. Whereas mechanical pumps used to be installed on the engine and are still in use, electric pumps provide higher pressures and efficiency and are governed by ECUs for safety and fuel injection systems. In total, the Fuel Pump is vital because it provides the desired volume and pressure of fuel to the engine for efficiency.
Each OEM Cadillac DTS Fuel Pump we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Cadillac DTS Fuel Pump Parts Questions & Experts Answers
- Q: How to check the fuel pump output and pressure on Cadillac DTS?A:Before you check fuel pump output and pressure in your Cadillac DTS, make sure the tank has enough fuel and release pressure from the fuel system. Pressurize fuel lines through a fuel pressure gauge that can release pressure with a bleeder valve and includes necessary fitting parts for your car. Start the engine but keep your foot off the pedal, and watch the gauge for two seconds as the fuel pump runs. The pressure reading should stay within the right limits. After starting the engine, it should naturally lower fuel pressure by 3 to 10 pounds per square inch. First, connect a vacuum source to the pressure regulator and put 12 to 14 inches of vacuum onto it. If the pressure drops now, find and fix the vacuum problem; if not, replace the regulator. When the fuel pressure is higher than recommended, check if vacuum is connecting to the fuel pressure regulator and inspect for crushed or blocked fuel return hoses. When fuel pressure shows less than the required amount, replace the fuel filter, and limit fuel return flow to test the regulator. When testing is done, let the fuel pressure escape before taking off the needle. To check electrical diagrams, have someone hold the car key in "On" position while you listen at the fuel filler neck for a whirring noise on top of the fuel filler cap. The whirring will confirm the fuel pump is working to pressurize the system. Make sure the fuel pump relay gets power from the battery at its cable while the ignition is OFF, and then again while the PCM is sending current. When no power reaches the relay connector, look into the fuel pump fuse and wires. Watch the relay and the fuel pump connector for voltage while the ignition key is turned ON. Turn power off from the pump and test it alone to see if it works. Also have a look at the oil pressure switch while checking if the fuel pump works after examining the circuit connections.
