Question about 2002 Ford F150 Regular Cab

1 Answer

Hard starting when warm after sitting for 10 minutes.

Hello,
I have a 2002 f150 with a 4.2 v6 engine. In the morning it starts normal. After you drive it and shut it off for 10 min. or longer the engine cranks for about 7 seconds before it starts. If you go to start it with in the 10 min. after shutting it off it starts normal. If the truck sits over night it will start normal. I'm getting codes saying that bank 1 is lean and bank 2 is rich. Could this be the fuel pressure regulator causing this problem?

Thanks,
John

    I have the exact same problem, the only difference is I have no error codes coming up. Did you ever find a solution?

My 2002 mazda premacy sticks in gear when the transmision is cold,what can i do to fix this


I would consider a transmission oil change to freshen up the oil . The hard braking may be that there is a rust build up on the rotors and that makes the pads grab for a few applications. May be a way to fix the gear problem is to start it and let it idle for say 10 minutes to allow everything to get some heat into it instead of starting and driving immediately

Long time before heater blows warm air


That seems pretty normal, the heater works by blowing excess heat from the engine coolant. So the coolant has to be warmed completely for the heat to work, you can get a heater that plugs into your cigarette lighter that will heat the vehicle instantly.

My Hummer H2 2003 model had a problem starting when its warm. Like when I start it in the morning, its normal, but after driving it for a few minutes and the engine is warm, I had difficulty starting


I had this same problem with my 2003 H2, my mechanic found that the fuel diaphragm was cracked and this was allowing my truck to flood. If it was a cold start, the extra fuel would evaporate and it would start fine. It actually got to the point where I would stall at a stop light or stop sign at idle. The part was is the neighborhood of $175.00 and about 1 hour of labor to install.

2002 vue v6...starts and runs well however when I stop , shut off the engine, then try to start after half hour , it wont start


Lookfor a light on the dash that says SECURITY or ANTITHEFT. If you see this light, that is a sign of a failed or failing antitheft system, which will disable your vehicle. This link explains

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.
