Car Starting Problems

Some of the common car starting problems stem from a discharged battery, a bad fuel pump (or no fuel), a weakened starter motor, or a broken electrical connection. Checking each part will help troubleshoot why the car won’t start.

Why would a car intermittently lose power when freeway driving then start after sitting for an hour?

Fuel filter is plugged or fuel line is cinked, after highway driving where fuel flow is greatest the pump cannot maintaine the flow and engine "runs out of gas" after an hour the fuel line is full again by gravity.

Run with a greater than half a tank until you get it fixed

You might have a faulty TFI (Thick Film Integrated) ignition module. Sometimes it is located on the distributor and sometimes attached to the engine compartment of the vehicle. If it is damaged and becomes overheated, the module will intermittently lose power as it heats up and then finally die on you. It takes about an hour for the module to cool down.

My guess is the fuel filter and or pump. the faster you go, the more fuel your engine requires. Thus, if the flow is restricted your engine may stall.

How do you reset the emergency fuel shut off switch?

The temp sensor helps tell the engine how to mix the air and fuel to compensate for air temperature. If this isn't working then the air fuel mix can be off and cause rough idle.

What causes a 1988 Lincoln Town Car to start and run for a while but when you turn it off it just cranks and will not start?

I'm not totally sure because I have to see it and take a look but it sounds like your starter is going bad. Either that or I would say that it is the solenoid switch gone bad. If this doesn't answer your question please go into better detail because I would like to help you figure tha problem out. :-)

Why is there no spark going to your engine?

There are a number things that can cause no ignition spark. A typical ignition system consists of an ignition module, ignition coil, some type of stator or pickup (distributer pickup, crank sensor, etc), plug wires that carry secondary ingition fire to the plugs(some have no wires, but individual coils directly on top of the spark plugs), spark plugs, wiring that provides primary power to the componets, wiring that provides grounds to the system, and some cars have a distributer(though distributers have been getting phased out for about the last 10-15 years). Anything at all in that system that has failed will cause no spark to one or more cylinders.

What does it mean when car starter makes buzzing noise?

It's typically either a discharged battery or a poor battery connection. Batteries are only an electrical storage device. If the alternator isn't keeping the battery adequately charged you could have the problem you describe. But rather than running right out and replacing the battery, first charge it and see if it will hold a charge overnight. Sometimes, if something is left on inside the car it will run the battery down sufficiently to cause what you describe. Other times it's the alternator, dirty battery terminal or even a worn out battery, but you can't know until you test these components.

Why won't a 1997 F-250 7.3 diesel start when the wait to start light doesn't come on it turns over but won't fire and the glow plug relay has been replaced?

AnswerMay be one or more glow plugs are bad.

you may also want to check the controller. it tells the relay how long to stay on. Your glow plugs don't stay on all the time. If your wait to start light doesn't stay on very long, then your controller is telling the relay to turn off. If the light isn't coming on at all then i would definetely check the controller. First check the 50amp fuse in the under hood block.

Dodge 91 diesel doesn't want to start when it does it starts 1 cyl at a time even after just running 1hr earlier and turns over like a gas motor maybe faster not normal any help out there?

Not sure if this will help ya or not but I use to work on hummers for the army. when our diesel's did that it was the glow plugs. So you might replace what ever part on there it is that makes the fuel ignight. I don't know much about regular diesel engines.
