Car turns over but no start

Check fuel pressure at the fuel rail and spark at the spark plugs.

Starts after several cranks when cold

engine temperature sensor ? On a cold start the sensor tells the ECU it's cold so the ECU adds more fuel until the engine is warm.

Engine light on, vehicle usually won't start. engine light code is o2 sensor

The oxygen sensor won't stop it from cranking or starting

Check for spark or injector pulse when cranking

Check fuel pressure at the motor shrader valve with a gauge

I have a 1987 ranger 2.3 EFI and sometimes it will not start when it's cold. after it warms up outside it starts. When it does start it runs great. It always starts when warm. some times it will

Timing belt being off one tooth will not cause this problem but rather loss of power and hard starting all the time,

in the cold it will not start, the engine will spin but wont fire is this correct?

There are many things that can cause this, a little testing will be needed, the first thing that comes to mind with the ford and cold weather is the coolant temp sensor, it give computer a false reading and can cause hard starting or even no start, a scan tool would be helpful to see what temp it is give computer.
The best way to narrow this down to to check for spark when it wont start, a weak coil in cold weather will cause this problem or bad coil wire to cap, but if you can see if it has spark and let me know,
another test is to check fuel pressure, to see if it is getting fuel, and the fuelpump relay,

Let me know if it has spark or fuel when is does not start, good day

Cranks for a long time to start up when it has sat for a while.suspect fuel pressure not staying in feul i have to drop tank to replace feul pump?

Check the Fuel Pressure at the fuel rail with a gauge first

Before you start replacing a fuel pump make sure
the other systems on your car are working correctly

Spark Plugs
Old Gas Filter
Old Air Filter
Dirty MAF Sensor
Old O2 Sensors
Clogged Exhaust Converter
Vacuum Leaks

2006 F-150 stumbles at start up,and sometimes cranks for a bit like an old carb engine does when its cold before it starts....5.4 engine...

New Spark Plugs--every 70,000 miles
Clean MAF Sensor
New O2 Sensors--100,000 miles
Fuel Filter-every 3 years

Check TPS Sensor for opens

2006 Lincoln Navigator, goes for weeks with no problem then will gor for weeks with randomly not starting until the 2nd or third attempt . Car usually will crank but not turn over.

Turning over is cranking
You mean will not start !!

Given it is 5 years old

Change the Spark Plugs,if you haven't
Change both front O2 Sensors at 100,000 miles
Clean the MAF Sensor --CRC MAF Cleaner

Next -- TEST the TPS Sensor on throttle body
It is replacable. (2) T20 Torx screws and a hair
dryer to soften the thread locker
You may be loosing the throttle position on start up

Then check fuel pressure, at the fuel rail on engine,
also if your not going to work on it yourself, have the TPS
and Fuel Pump looked at with an Oscilloscope

The fuel pump may be going bad

I have a 2006 Freestar with a 3.9 Engine . When it is cold it has a miss when i step on it. But it gets better when it starts to warm up. Almost seems like a spark plug miss

Spark Plugs ---change at 70,000 miles
O2 Sensors--change at 100,000 miles (front 2 only)
Gas Filter--every 3 years/30,000 miles
Air Filter ---every 3 years/blow off once every year
MAF Sensor---Clean once a year or more often

Ignition Coils--- most definitely will go bad,at
least 1 a year. (Any Check Lights or Codes ? )

When cold, it isn't in closed-loop, and runs on
Long Term Fuel Trim--not on O2 Sensors ,until

Let it warm up at least 4 minutes in cold weather,
go light on the gas for first 2 miles

Starts dicent when cold but when it warms up it starts running so b ad it wont accelerate and will finally die

Do you see black smoke coming out the back at all, once it warms up? To me, it sounds like your oxygen sensors are going bad. If you have a 1996 or newer, change the oxygen sensors between the engine and the catalytic converters. If it's a 95 or older, you'll only have one set. Change them out.

The O2 sensors determine what the fuel mixture for the engine will be. They are ignored when the engine is cold, as they have to be up around 900 degrees to work. Once it warms up, feedback from the O2 sensors is used to determine how much fuel is needed. When they fail, the car defaults to a rich-running condition, with excess fuel being dumped in. This is because the computer doesn't trust the sensors, so it adds extra fuel. Running rich fouls spark plugs over time, and causes hesitation and bogging and bad gas mileage, but it's better than running lean (too little fuel) - that blows engines. So the car is programmed to err on the side of caution and richen the mixture. Change the O2 sensors and the spark plugs, and you should be good to go.

I have a 1996 Ford Contour, 4 Cylinder Engine. I have replaced the O2 Sensor, the Fuel Filter, and The Spark Plugs. The Engine cranks and cranks, taking forever to start. On a few occassions it has drained...

I doubt if it is the pistons or PVC valve. It is either a fuel or a spark problem. First check the spark and make sure it is good and strong, if you have a strong spark the problem has to be fuel flow related, maybe the fuel pump or the injectors.
