If I had to guess this sounds like a four cylinder engine, with one or even two cylinder's misfiring. Best guess is a problem with either a spark plug wires, or an ignition module. I'm looking at high resolution photos of your engine compartment and its not clear on what type of ignition system you have. Generally there are two types of systems. One has a ...

Sounds more like a problem with the ignition switch, possibly some kind of interference with the steering wheel lock. Do you usually park on the street with your wheels turned? If so, maybe try to make sure your wheels are pointed straight before you shut off the car. This should take the binding out of the steering linkage and put less stress on the ...

Common things that can shut a car down after starting: bad or disconnected idle air control valve (hold the accelerator down after starting, see if it keeps the engine alive) bad or disconnected mass airflow sensor bad ignition switch blocked fuel filter (test your fuel pressure) weak fuel pump (test your fuel pressure with the engine off but the key at ...

It sounds like the car is unable to maintain sufficient pressure in the fuel rail. Have a look at this answer for more details on potential causes for hot start problems. It is usually a good strategy to confirm suspicions through measurements and/or diagnostic tests, many of which can actually be performed by an average DIY-er. As you saw with the MAP ...

Check all the fuses and all the fusable links, hopefully he fried one of them. The colour of the fuse means the amperage that it can handle, it is the bell-shaped curve inside that you are checking. Look for a gap. Here's a good vs bad comparison. Fuses are cheap and easy to replace.

The list for why the car did not start is long. Instead lets hit some basics. First to successfully bump start a modern car the battery cannot be completely flat. (that is less than 8v or so but depends on car) This is because the alternator needs some electricity to excite it to generate power. The car may not have enough power to turn over the starter ...

As in the other answers, first check if you are or not getting power to those things that gets serviced when you turn the key. If you have a flat dead scenario here, then you need to check the ignition key. If you get these loads working (lights, radio, etc) and if the starter doesn't turn, check starter fuse, starter relay and starter exciter wire to its ...

What you're describing is almost certainly an electrical problem (or two). It sounds like two things are happening and they are quite likely related: Something is causing the engine to shutdown (your may find What can cause a gasoline engine to suddenly & mysteriously stop helpful for thinking about what could be happening). Something is causing the ...

The symptoms that you're describing sound like a poor ground connection for the starter motor. The starter draws way more power (i.e., current) than any other load. If you don't have a good solid connection it is likely that the motor won't be able to run, or won't develop enough torque to start the car. The battery posts are slightly tapered and the slight ...

It is possible the issue is at the ignition switch. The best way to test will be with a schematic and a test light to see that the ignition switch is getting voltage in, but is not putting voltage out when the key is turned. If the ignition switch does put out voltage, follow it down the line to the starter relay, and the starter. Also be sure to check ...

The "Depress clutch to start" gadget should be dealing only with a starter motor relay. Everything else should be working anyway, so if your "Bump-Start" was at low speed and 1st gear, then yea, it was a faulty "Bump-start". Normally it should be done at 2nd or even 3rd gear on diesel engines because of very high compression..

If you are playing with engine wirings, always disconnect the battery. ECU will never fail and will last forever unless something mechanically damages it, or you have a shortage where it is not acceptable. Normally ECU works on 12v, sensors 5v. ECU is very sensitive box, and it "burns" if you mess up the wires. I personally saw my co-worker "repairing" a ...

A dead battery or a weak/dead alternator are the usual suspects with these symptoms. Here's what you should do: Get yourself a $15 multimeter (WalMart has them). Set it to "VDC20" and put the leads on your battery terminals. A healthy battery will read 12.4V or higher, anything less than 11.8V will be insufficient to start the car. If you are reading less ...

Try this, 1) Turn the key to the Run position and leave it for 10 minutes. 2) Shut the ignition off for 10 seconds. Repeat steps one and two, two more times and try cranking. If that doesn't work you need to go to a dealer to have the ECM reprogrammed or disable the VATs system.

The issue of not getting started means that there may be a problem with self-start mechanism or battery (in most cases since it is not an old vehicle). Unless you are not having a very cold day, always apply Choke. If not, then observe the sound from Engine that Self Starter usually makes while you Crank start the engine. If it is feeble or unusual, then it ...

You always need to apply the choke when starting a cold engine. Until the engine is at operating temperature, it needs to run a bit rich to run properly. The choke allow the engine to run rich. 5-7 tries does sound a bit much. Is there a way of priming the engine to ensure fuel is getting into there before cranking?

Please stop testing your starter with a screwdriver! You could get hurt. A simple volt-meter or multi-meter is a good investment for a home mechanic. Is your starter cable fused? Check the fuse with your new multi-meter and then you can check the voltage back to the battery negative post. It's possible the earth strap has come off your engine and there's no ...

Brenda, You could have one of fifty troubles giving you a no start condition. To run, a car needs a control system, and functional electricity. The engine needs spark, fuel, and air in the proper mix. Any defect could cause troubles. But the good news is your car is equipped with a computer system that manages a good portion of these things. It also ...

Make sure you are in Park and the car knows it. I've had this happen to one of my vehicles where the shifter would be in Park, but the car wouldn't see that it's in Park because the shifter was "wobbly" when in Park. The shifter was clicked into the Park position, but it could still move around a little bit and stay in Park. For my vehicle, I need to give ...

For some reason the site won't let me add comments . I have a firend that had a similar problem with his 06 it turned out to be the control module that turns off the battery if the door is left open he ended up putting a switch on the battery, opening the switch and closing reset the system. This was easier than pulling the battery cable and cheaper than ...
