You don't say what engine you have but, if you have the 2.4 inline four, remove the engine cover, locate the fuel rail, remove the schrader valve cap, turn on the ignition (no start) torn off the ignition, now press the center pin on the schrader valve. (just like a car or bicycle tire valve) You should get a pretty good squirt of fuel. If you don't the installation of the new fuel pump is faulty. Changing the fuel pump is a pretty serious repair job. Mechanics do not like to do this job.
