SOURCE: 1994 corvette wont start

Dunno if it is your problem but have had this same 'died without warning' effect from nothing more than a corroded battery clamp or terminal at the starter with the same problem.

A cheap multimeter will tell you if there is any life at all and by measuring at the terminals when having someone turn the key, then doing the same at the clamps themselves will tell you quickly if it is simply failed contact at the battery.
If the battery measures ~ 12.6 volts with no load (nothing turned on) and still the same with the key turned to start, then the terminals are at fault.

Something I have never seen before happened to one of our sons just yesterday; his Optima (costly) battery lost contact INSIDE of the battery!
It measured zilch until we dropped it on the ground (on purpose) then it measured normally 12.6 VDC.
We reinstalled it and again, as soon as he attempted to start the Jeep, even the underhood light went out and didn't come back on and the battery again measured 0 volts.

SOURCE: wont start

There's only 2 more things that I can think of, check the fuse for the ignition, then the computor itself, you did everything else.It might be the problem and may not.

SOURCE: My Dodge Neon will crank, but not start?

If you are asking about the battery light, there is a battery temperature sensor at the front of the battery tray to the right of the battery holddown hardware. If the snow loosened the wires or blocked the airflow to the sensor, the battery light will come on. The battery and alternator voltage can be correct, and the sensor will make the light come on.

SOURCE: i have 2003 cad cts mt new battery,new starter

does the vehicle have an anti theft device on it if so it may need to be reset. usually all you have to do is unlpug the negative batt cable. for about 5 mins.and reconnect it. if this does not solve the problem look i the owners manual to see how to override the system.

Van will not fire turn key off and on several times and it starts


Use a gage and check proper fuel pressure. Cycling the key on and off several times before you crank it, allows the fuel pump to prime the system.
How long since a tune-up? Are there any applicable trouble codes?

Why wont my BMW 93 525 I wont start turn over but will not start


When you turn the key to the on position do you hear a buzz from the rear of the car for several seconds? If not possible bad fuel pump or relay or fuse. If you get the sound check the ignition coil for spark. Pull the coil wire and have someone crank the engine for you Observe if there is spark going to ground. You first need to know which system has failed.

My BMW 520i starts up when cold but when it's warmed up and I turn engine off it won't start it's a 1997 straight six tiptronic whats causing this?


If the engine cranks but fails to fire, the car may be flooding due to a failed temperature sensor. There are several, but the most likely problem would be the water temperature sensor.
If the engine fails to crank when hot, the starter motor is failing and will need to be replaced.

I have a 1996 BMW 318TI and when I turn ignition, the engine dosen't turn, but when i put a remote starter the engine turns, but no spark fire from spark. I need a solution to fix this quick!


Does the key have a alarm on it if it does youll need to replace the battery in the key.When the key is put in the transponder sends a signal to give spark and it does.then it starts. If you say the key doesnt have a alarm try this when the key is turn to the ACC position do you hear the pump. now if you crank it with the remote does the pump turn on? If yes you can do this go to the crank sensor pull on the harness(crank sensor has a tendency to get loose) does the crank move if it does youll need to tighten it up with the proper gap. if it doest solve it do this. close the door with the battery at a proper charge put the key in the door unlock it get in put the key in ignition now does it crank. If no you have a alarm problem.

No crank


shorting to start motor will allow the motor to turn but the ignition system is still off.
try with key turned to ignition position.
suspect starter solenoid on starter motor.
suspect fuses maybe there is a fuse which has blown.
suspect ignition key switch maybe defective.

My 93, 318I won't start


if you think your cambelt has broken ,when your trying to crank it over ,your engine should turn over faster but will not start.,to check if your fuel pump is not working,turn the key whithout turning over the engine and listen if your fuelpump buzzess than you know your relay is not faulty,.i gather your bmw is a E39 model fitted wid a distributor cap. check your ignition coil plug pins for rust,or your modulator cables/plug connection.

Bmw 318 i cranks but wont turn over


Ok , when u turn the key the engine cranks (turn over is the same as cranks), but it won't start. U have to determine if there is spark at the spark plugs, if there is then u have to determine if gas is reaching the spark plugs. This must be fixed 1st before the running hot issue, and I don't believe the catalytic converter has anything to do w/ your problems you have described.
So 1st u must get the car running again. As far as overheating, why did the shop think it was the head gasket? So u have several problems, but unfortunately, not enough information to work with yet. Let me know when u determine if the no start issue is due to no spark, or no gas. Good Luck!
