Why would a car start and drive then later turns over but does not start?

Answer 1

You have to fix the problem causing it first. Find out what is missing. On some newer cars, it is easier to check for spark, than it is for gas. On other newer cars, it is hard to find out either, or, because of their lack of having high tension wires. What year/type car do you have? E-mail above.

Answer 2

What make of car and year would help ? A good place to start looking is does the car have an electric fuel pump ? If the the fuel pump is getting worn it will cause the problem you are having , hope this helps

Answer 3

A typical senario with fords in general.

Just a stab in the dark.

Has it got spark.

To test for spark, place a screwdriver in the end of the lead. wave the screwdriver over the rocker cover about 2 to 3 mm above it and get someone to crank it. If you see no spark, I'd replace the ingition module.

It's located inside the distributor.

You will need to remove the distributor to replace the module.

You will need to mark the dizzy. I usually you a centre punch. Punch two dots, one on the head, and one on the dizzy, next to each other. That will tell you the position of where the dizzy goes.

Next remove the dizzy cap.

Notice where the rotor button is roughly. Cos the dizzy can only go in two postions. The right position and 180 degrees out.

Undo two bolts which secure the dizzy and remove dizzy. Good oppotunity to cha nge the dizzy o-ring cos they often leak after disturbing the dizzy.

Dismantle the dizzy and replace the module. Pretty self explanitary.

To test. With new module in, turn ign on. and spin the dizzy byt hand, you should see spark.

That's usually what goes wrong in Fords if it's got no spark. If it's got spark, is it getting fuel. Pull hose off end off fuel filter. and see if it's pumping fuel. Check both sides of the fuel filter for blocked filter.

If not pumping, replace fuel pump. They usually blow a hole in the diaphragm, so it won't pump fuel.

Other then that, that's what usually happens.

I would only imagine one would first have to diagnose why the engine wont turn over??? is it the battery???starter???bad connections at the battery,solenoid??? defective starter solenoid??seized engine??hydro locked engine???no ignition key in ignition switch???broken ignition switch???vehicle unable to shift into park????No engine oil in engine for quite some miles, a metal pipe stuck into the engine oil pan(flew up under your car while driving high speeds on the interstate) and you didn't realize it until you got into Florida from the occurance 1,000 miles back in New Jersey??Is this your vehicle or a different vehicle that has all the same equipment as your car and is also parked in a Wallmart parking lot and you are not aware of the differences but can't get the ignition key to turn on due to the indifferencesLOL, good thing the doors were left unlocked????

At any rate when the condition is determined then and only then can one attempt to make the needed repairs.For example if the starter is defective....replace the starter....if its the battery....replace the battery....if its the wrong vehicle parked in a similar parking spot to where you parked your vehicle....locate your vehicle and attempt to start it.

Answer 5

There are the failure triangle to test first:

• Fuel, in a fuel injected car checking for fuel pressure will do to start.
• Spark, remove a spark plug and hook it to its lead or coil and lay it on a metal part of the engine, when it turns over is there spark?
• finally is there compression, rule of thumb is you need more than 110 psi to start, but check against specification if possible.

From there you have to figure out why you don't have one of the needed triangle.

Answer 6

In order of probability for cars more than 8 years old, the order changes for newer.

• Dead battery
• Bad starter
• Hydrolocked This means the cylinder is full of oil, fuel, water, coolant or other fluid. Remove spark plugs, rotate engine.
• Transmission or accessory siezed (Alternator, water pump etc)
• Thrown rod or other serious internal damage.

Answer 7

The starter turns the engine over.
