Possible fuel pressure bleeding off, either back into tank,or injectors not sealing when off. I would run a fuel injection service first then if still happend put mechanical fuel pressure gauge on it and observe pressure over a 20 minute heatsoak

Force 120, 1999, no start cold, stalls out after running for 10 min, cranks hard restarts after sitting few minutes. Think fuel pump, any mercy mechanics out there that can give me a hand with this


Don't know this car. Check fuel pressure with a fuel pressure gauge- if correct, not a problem with the pump. Also make sure the pressure will hold for some time with key off. It should hold pressure for several minutes, maybe 20 minutes, some maybe a bit less, but it must hold pressure for a time. If pressure is good, check for spark when it won't restart. If spark is lost, suspect the crank position sensor.

I have a 1989 Ford f150 drive for about 30 minutes it dies out or stop and want crank for about an hour


I would unplug the gas cap when it stalls; if you hear a hissing sound, change the gas cap, because it builds up a vacuum in the tank.

There are several things that few people know about starting cars in cold weather. 1. Check your battery to make sure it is not rusted, leaking, and has a charge 2. Jump start your battery with another car, even if you believe the battery is good, this often times will still start your car. 3. If your engine is cold, and you have an older car, ensure to get your fuel lines to the engine flushed or have fuel injection service performed 4. The engine tends to warp the same way wood does during the extreme cold, do not be afraid to continue trying to warm up the engine by constant cranks with it is cold out. Your not going to hurt the car, the worse that could happen is too much fuel will enter the carborator and cause flooding in the system to occur. Wait 20 minutes if this happens and start to crank again 5. Bad spark plugs are a major reason why many cars take a very long time to start 6. Please have your spark plugs removed and exchanged for new ones. Over time, spark plugs become fowled and prevent the car from starting even thou you hear cranking!!!

I'd be tempted to have fuel pressure checked, if at all possible, when it quits. If nothing else, carry a can of quickstart with you, and when it quits, remove air intake at throttle body inlet, and open throttle plate and give a good squirt of quick start, then try to start it. If it starts for a second or 2, then you know you have spark, but no fuel. I've seen fuel pumps work good while cool, and cut -out when it gets hot. Then sit and let pump cool off for 20 minutes or so, then pump up to pressure again and away we go, until it gets hot again. You might also find if you park in the shade, you'll get further, or even on a full tank. Another good idea would be to change fuel filter in case fuel pump is working too hard pushing fuel through a plugged filter, and causing low fuel pressure.

Car won't start


yes, the security system will cut fuel to the cylinders or stop the car from cranking. what you can do is called a 30 minute re-learn. have everything turned off and a charger hooked up to the battery if possible, put the key in and attempt to start, release key to the run position and let it sit for about 10 minutes or untill the security light goes out. turn key off for 5 seconds and repeat the process 2 more times. after the process is done 2 more times the car should have re-learned the key and it should start. if it still doesn't start the problem might be somewhere else in the security system but try the 30 minute re-learn first. i can assist you with this problem further if needed as i have excellent resources.

hope it starts for ya!
