If this occurs, operate the priming pump several times in between starting attempts. To Prime the Vehicle (Van Models) The vehicle has an electric priming pump. The priming pump is operated electrically and is designed to bring fuel to the engine to eliminate any air in the fuel lines. Correct the condition that caused the loss of prime by making sure there is fuel in the tank. After completing the initial prime in Step 2, turn the ignition off, then back to start, and crank the engine for 15 seconds. If the engine does not start, repeat Steps 2 and 3 until the engine starts. If the engine does not run after repeating Steps 2 and 3 three times, turn the ignition key off for 60 seconds, allowing the Electronic Control Module (ECM) to reset. If the engine runs, but does not run smoothly, increase the engine speed slightly by pressing the accelerator pedal. If the engine starts and runs but stalls again, turn the ignition key off for 60 seconds to reset the ECM and repeat the steps above. When the engine starts, let it idle for a few minutes and check the filters for any leaks.
