If the corroded or loose battery terminals prevent the car from starting, creating a slow cranking, and causing the “car struggles to start, but runs fine” condition. To fix a car that doesn't start, you'll first need to diagnose the issue.
Repeat that about 3 times.
Car having trouble starting but runs fine. The gas has to be pumped and turn over the engin and car will finaly start. Corroded or loose battery terminal or cable. If the lights and horn work, but the starter motor doesn’t crank, or it makes a grinding noise that turns into clicking, the starter motor or an electrical relay or starter solenoid could be bad.
When the engine is started cold, the engine temperature sensor sends a signal to the dme control unit to provide a richer mixture. Car has trouble starting but runs fine. Start with the easiest things.
Then the engine starts up again because startup requires little fuel. My car runs fine, but has trouble starting when engine is cold. The car has 60000 miles on it.
If engine spark plugs are not dirty or damaged, then the choke needs to be repaired or adjusted. Once it starts, it runs. When your engine cranks but won't start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression.
A symptom of starving the car for fuel is a car that runs correctly at idle and low load, but falls flat on its face as you ask for more power (when climbing a hill, for instance). After the 4th key cycle, try to start the engine, if it starts up normally and runs fine, it is the check valve. If the car does not get the proper enrichment when cold, it will have trouble starting, or run poorly until the engine warms up.
After the car runs for 15 to 20 minutes and sits for 15 to 30 minutes it is very hard to start. What is so pivotal about these three components is that to successfully run and drive the vehicle the engine needs fuel, compression, and a spark all working simultaneously. Why won't my car start?
However, there may come a point in time when your car will actually start but then die almost immediately afterward. Last week when leaving work my car started very rough. Normal wear and usage can cause a hard start condition due to lack of fuel pressure, poor intake air management, false readings to the car's computer or weak spark.
The service engin light stays on also. It has enough for idle, but can't keep up as rpms increase under hard acceleration. If either of those wires are making a poor connection or have become broken or corroded they could be giving a weak signal or insufficient power for your car to start.
When you attempt to start your car, you normally assume it is going to start without any problems. Mostly starting problems relate to a choked carburetor in cars. My question is could it be the fuel filter or more likely the pump or something else.
About a week later on my way to work the car seemed to ‘sputter’ (for lack of a better word) when i pushed. This was unusual so i killed and restarted the car about three times before letting it run it’s course (~30 seconds), after which the car ran fine. If that is the case you can try replacing the wires or cleaning the connections.
Then car starts running rough,. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter). Turn the key on, wait 3 seconds, turn it back off.
That will cycle the fuel pump on and off to fill the lines. There are many causes of hard starting but illustrative ones are a faulty engine coolant temperature switch (sensor), malfunctioning idle air control (iac) valve, vacuum and egr leaks, inadequate fuel delivery or pressure (clogged. Sometimes the engine will start immediately, then other times it just talks a little longer to start, but the battery isn't able to supply the power, then you are in the situation you are in now.
I have a ford focus mkii (british market) with the 1.8 duratec engine that is very hesitant starting when warm. You’ll hear the engine turning and everything will seem fine. In this case, check the fuel pressure from the fuel pump.
Two, your engine is having difficulty obtaining fuel. The service engin light stays on also. If the battery has a charge, the starter is fine, but you still can’t get the engine to turn over, it could be a faulty ignition switch causing your trouble.
If your car engine turns over, but the car won’t start anyways, it is time to check the spark and fuel. Engine starting and running troubleshooter. If the vehicle won’t crank or start but the headlights are still working, look to problems with the starter or other parts of the engine.
Three, your engine is creating compression. Some of these repairs are simple and are included in the normal maintenance of the engine. I have a 1999 ford escort se wagon with 112k miles on it.
If turning the key to start doesn’t produce any noise, then the ignition switch or neutral safety switch could be the culprit. If your car struggles to start but runs fine, this is a sign of a battery issue that can enhance the car’s performance issues. Sometimes this issue makes your car hard to start but runs fine once it gets going.
If the car starts when cold but, idles rough or does not want to stay running, this can indicate a problem with the engine temperature sensor. These complaints are mysterious at first, but once you learn the common causes, you can often cure them with little to no trouble. What you need to do is start the engine, turn on the lights and the heated rear screen then check the battery voltage.

Fuel pumps may fail due to age, sediment buildup, or running the incorrect fuel. One, your engine is having trouble producing a spark. Don't try to start the engine.
