The car stes a P0100 and a P0335 code. The 335 code will reset but the 100 code does not.


p0100 is the mass airflow sensor. You might can clean it with carb cleaner first, if still don't work then replace the sensor.

Hard to Start when Warmed up


You would need to figure out if you are missing spark to the plugs or fuel pressure when it fails to start. It could be something electrical like a relay or the coil.

Once warmed up and it sits for 30 min. It's hard


Check your fuel pressure it should be 60-66 psi with key on engine off.Sounds like it could be a weak fuel pump.These motors need at least 52 psi to open the popet valve in the injectors to allow fuel thru.

Pump the clutch. several times turn vehicle on now is it easy to go in gear if yes then you will need a clutch hydraulic that means a slave and clutch housing unit.

Hard to start initially, but once warmed up starts right up. Also OD off light and check engine light on.


you have to get the computer scanned and see what code is being stored, this will tell you what area to diagnose.

Does the 2002 regal have a cold motor sensor Car hard to start when cold motor (in the morning )


Your vehicle uses the coolant temp sensor and the intake air temp sensor to determine the engines temperature on a cold start. If one of them is dramatically different than the other it will flag a code.

Is the check engine light on?

When was the last time you had a tune-up? if recently what brand of plugs where used?

Have you noticed any hard start issues after a hot soak? A hot soak would be driving the car until fully warmed up, shutting of the engine for approximately 15 to 20 minutes, and then starting the engine again.

F250 hard to start once warmed up.


You may have a CTS (Coolant Temperature Sensor) problem. If the coolant level is low the CTS could be sending a false signal to the ECM or the CTS may be faulty. The CTS must be in coolant to provide an accurate signal to the ECM and if the coolant level is low then the ECM thinks the engine is cold and therefore provides a rich air/fuel mixture. This, in turn could be the cause hard start (evident by black smoke from the exhaust), and could be the reason the vehicle failed the emission test.
