More then likely it is the alternator that is bad, or a slipping belt. the voltage at battery with car off should be about 13 volts or a bit higher. while running, voltage at battery should be at or about 14.2 volts.

Two things, 1- check and make sure the drive belt did not come off. 2- need to do an elec. check, if belt is ok, then more then likely the alternator has gone bad, if you can jump start your engine, check voltage at battery with engine running and jumper cable's remove, with volt meter check voltage at battery, that will be alternator out out voltage, should not have less then 13 volt's, if less, bad alternator, replace it.

SOURCE: car want start factor security light flashing and

The factory security light will remain on - this is a standard feature indicating the car is dead.
First, unplug the hazard fuze in the engine bay (this will reset the ecu and remove the flashing)

Next, replace the battery with a new one (or one with proper charge) - keep in mind a small battery will not do anything for these cars, the engines require a lot to push them over (it isnt a honda)
*Make sure to clean the positive and negative battery cables from acid

Then just start it up :)

SOURCE: i lost my key to

Your ignition takes a specific key, they are chipped. If the ignition was changed and the decoder wasn't , this is the problem. You may be able to call a dealer ship and give the VIN number and get the measurement in ohms of the chip, Maybe. Then go to a hard ware store and they can duplicate the key you have with a chip key. Be prepared , this is not a $2.00 key

98.3hombre battery went dead after a jump it wont start


double posted, why?
JUMPS OK
AFTER JUMP WORKS AND DRIVING, AND STOP AND KEY OFF
IT WILL NOT CRANK.
did i guess right?
that means ,
check all fuses first. even the alt fuse (large)
1-battery bad? #1 top failure all cars.
2-Charge system bad. (is the charge/ batt warn lamp glowing when running car, bingo.????

3-or phantom drains. (if no crank just after stall then it not this) if drains while sleeping yes.

the tests are easy, a dirt cheap voltmeter
13.3v to 15v running is good charge system.
if 12v and falling not.

if the battery is bad, the charge system can shut down, so, the best practice is to try a know
good battery out of 2nd car, do you have battery to barrow, this is TOP CHOICE< not thinner wallet.

if the good battery fails then the charge system is failing (note I said system and not a part)
or the belt missing or slipping to the alternator.

btw the 4.3L PCM runs the alternator
PCM is engine brain.
btww, same true 2.2l engine.
the regulator is in the PCM.

so is the charge/bat lamp in cluster
on key on, lamp test
the jump start it , it runs
does the charge./batt.lamp go out.
id be all over that lamp, costs nothing to look.

Car battery went flat an tried jump starting an didn't work put another battery in an now wont start an hazard light an all other lights are flashing


Battery went dead or replaced, it set the alarm. Some alarms can be reset with the key, some with a scanner, some at the dealer. Year, make , and model would be helpful.

"have spark at coil down to dizzy but no spark at plugs"
this can mean only 2 things.
1: spark wires are dead. all 4, kinda hard to believe huh?
2: the dizzy is way off time. so time the dizzy and now spark
lands on each wire term.
if not a dizzy engine, post exact version of engine and country.

Wont start engine light flashing


Have you tried to jump the battery and crank it ?
Its possible the alternator failed or something happened to drain the battery.
Is the security warning light on ?
