Car Hard To Start Then Runs Fine

A loss of pressure over time will cause the fuel not to be at fuel injectors when starting and will take time to build up pressure again before it will start normally. If it does, either the fuel pump is getting weak, fuel filter partially plugged, or injector is leaking off.

5 Reasons Why Your Car Wont Start Fiix

Now the car will not start without starting fluid.

Car hard to start then runs fine. So i have an 01 sonoma 2.2 flex i've been fighting with for months. Sounds more like a fuel pressure drop. However, there may come a point in time when your car will actually start but then die almost immediately afterward.

It doesn’t stall but the engine sounds rough like an old 80s car. The pump should only have power at start and when the engine is running. Probably not enough fuel is getting to the cylinders.

This is an indication of a loose fuel fitting or a faulty valve in the system. Not sure about waxstats, will need to check. My car takes between 3 and 10 seconds to turn over when you try to start it.

You’ll hear the engine turning and everything will seem fine. If the engine starts right up and runs smoothly, the problem is with the fuel pump check valve allowing fuel to drain back into the gas tank as the vehicle sits. Holding pedal down to try and clear flood does nothing.

If your car does run fine, and there are no signs of leaks, smells, or bad wiring, this could be your issue. After starting the van will run normal. The gas has to be pumped and turn over the engin and car will finaly start.

When starting fluid is used, the car will start and then run fine. I thought so but i went out this morning after it sat all night and it started hard but it did start a little better. But, if the engine fires up with starting fluid, then check for fuel pressure.

You may also have a slow to start car due to a worn starter, a common issue. The car is a 2008 nissan versa with 120,000 miles on it. Also while idling very rough the brakes are very stiff.

Renault kangoo hard to start , then runs fine. The service engin light stays on also. Two possibilities are that your fuel system might not be holding pressure or your cold start valve is not working.

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 fuel filter, injectors), and contaminated or old gasoline. After the car runs for 15 to 20 minutes and sits for 15 to 30 minutes it is very hard to start. Then, all of the sudden, it starts revving and running better.

The started itself should also be inspected for signs of wear. Too much wear may mean you need a new starter. The fuel pump turns on when key is in on position.

Posted by esereth to travel & transportation (13 answers total) Let sit over night to soak then in morning run in low gear at high rpm to burn out any carbon deposits. An engine needs a minimum cranking speed to start if the starter or battery is weak the engine cranking rpm will be low which causes the engine to build compression slower and make it harder to start.

This is what i have done: Maybe there is something wrong with it causing it to not get off cold start mode which is fine when the engine is cold but once it warms up floods the engine and makes it hard to start. The alternator, battery and starter have all been checked twice and are perfectly fine.

(updated on may 4, 2020) when you attempt to start your car, you normally assume it is going to start without any problems. As you know by now, the battery is responsible for producing the power to start the car. This can be caused by.

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. Since i wanted a p28 i wired the four wire o2 and the two heater wires are commonly mismatched as they are the same color white with my bosch sensor that i bought, let me try switching them around and see. The car has 60000 miles on it.

Turn the ignition on and see how much fuel the pump is pumping, you shouldn't need much on a carb engine so it will be obvious if there is a problem. Once it starts, it runs perfectly. My car runs fine for a few minutes, then starts sputtering and loses a lot of horsepower.

I recommend having your starting problems inspected by a mechanic. When i start it from time to time it runs very rough, backfires, and the tach fluctuates from 500 to 3000 rpm's then smoothes out after a few minutes and runs fine. Try turning the key to the run position(do not try to start it, just have the dash lights on) for 2 seconds, turn the key to the off position.

My question is could it be the fuel filter or more likely the pump or something else. Sometimes this issue makes your car hard to start but runs fine once it gets going. Repeat this a half dozen times and then try starting the engine.

To do this you will want to remove the fuel rail and leave it connected to fuel line over night with rags under injectors. We are in a sudden coldish snap (dipping below 30 f), the fuel is a few months old (more than 3 but less than 6), and i just had an oil change a week ago, before this started, and nothing was noted. Once you shut it off then try to start it, same thing.

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. If compression is good on every cylinder then you will want to test injectors. Next, move on to check your battery and all of its connectors and wiring.

If that is the case you can try replacing the wires or cleaning the connections. I am getting pretty crappy gas mileage also. Do this 3 times and see if car starts easily when you try to start it.

If it is an efi (which just about every car has been for a long time) car maybe the car has a bad 02 sensor, if it is a very old car it could be a carburettor car with a carburettor problem. I let the car get stone cold for a couple hours and it was starting fine wahlah right.
