SOURCE: Vehicle Won't Start

The solution to this problem was simple, embarrasing and frustrating. The dome light was left on, and discharged the battery....enough to prevent the ignition from firing apparently. I did not suspect this, because the starter would turn the engine over very well, for a long time, and would do this repeatedly. In all my experience, I have never seen an engine spin that well and not start. According to the dealer, the voltage was too low for the ignition to work. While I do not know the exact threshhold where the voltage is too low to crank, I could have detected the condition by checking the voltage at the battery while cranking. It should have been significantly below 12 volts, indicating a low battery. The tow truck driver who picked it up simply used a portable battery to jump it off and cranked it with no problem. The symptom of the starter continuing to run after releasing the key is new technology with computerized controls, and is normal nowdays. You don't really notice this because the engine usually fires so quickly that it is undetectable.

SOURCE: my 1999 gmc savana van turns over but does not

could be a bad fuel pump, or fuel pump relay. they are having problems(a lot) with the ethanol in the gas on GM products.Fuel pumps sales are through the roof at parts house on GM's. Have a pressure check on your fuel system. That is probably it. Add a can of Seafoam to your fuel every 3000 miles to alleviate this problem.

SOURCE: once in a while my 2003 gmc safari will not start.

Could be bad starter. Miles don't matter, only how many times you start the car. I would first check for corroded or loose connections between battery and starter solenoid..

I would replace the starter and /or battery. Both can be checked at a parts store. Sounds like you may have a short in the starter, draining the battery.

Mini van wont start battary charged new altanator and starter all wires are grounded


Do you mean it won't start, or won't crank.
You should have a neutral safety switch between the key switch and the starter to prevent you from cranking the engine in drive or reverse.
A defective switch would keep the engine from cranking.
A mechanic would check for voltage at the starter on the wire from the key switch and go from there.

1997 gmc sierra 3500 won't start


When you turn the ignition to start, do you hear the starter turning and the solenoid engaging the flywheel ? test your starter by jumping it and see if the engine turns over. If this works, then you might consider in checking fuel pressure. Do you have any codes in your ECM ?

It won't die when pulling the relay because it has another power path to the fuel pump through the oil pressure switch .

Plus when it won't start ,don't guess or theorize !

Hi, the electric fuel pump in the tank may be bad, causing a no start. it should run when the key is turned on, for two seconds, then stay running when the engine is cranking, or running.The pump should put out 55 psi, this should be the first item to check. Good luck...

It just clicks when I go to start the engine


Check your battery connection's, if when it clicks one time do the lights go off?Then more then likely bad battery connection.With light switch on move battery connection if lights come on you found your problem.
