Sometimes, if there is no fuel pressure, your engine might even quit while running. The main cause is that the new pump lacks the appropriate pressure to send fuel to the engine.

You may have trouble starting your car engine, or the car cranks for a few seconds before starting.

Please let us know if you have further concerns or questions as we are always here to help you. Regardless of the underlying cause, if you request a no start diagnostic the responding certified mechanic will get the problem diagnosed and repaired for you promptly. Other common faults are defective spark plugs or a defective coil. Such could be due to a big vacuum leak, an air induction fault like a stuck idle air control valve or, considering fuel, could be due to a failed temperature sensor that must be working properly to signal the PCM to enrich the mixture on cold start.

If there is fresh fuel being delivered by the injectors (not just 'to' the injectors) and the ignition system is working, that means that the air fuel ratio of the mixture delivered to the cylinders is so far off that the mixture just won’t ignite. Basically, if the starter motor is turning the engine over rapidly, at sufficient RPM, but the engine does not catch and run, that means that there is an ignition, fuel, air induction, or mechanical fault in the engine that will have to be repaired. Check for adequate fuel pressure, injector operation, and a spark at the spark plugs. Be sure there is adequate fuel in the fuel tank and that the fuel is not old. Of course, confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting.
