99 suzuki vitara v6 turns on all power but wont


the starter uses 10x more elect. power than the head lamps
or 100x more than dash lamps. it means little.
what matters most is jumper cable starts.
does it crank with jumper cables to a running, donor car,(aaa jump)
no bad starter
no, bad starter key line( immobliizer or such) ask how to test.
yes, cranks great, now.
that means the battery was dead,
i charge the battery and it now cranks, due to lights left on or
charge system failure, if battery goes to 13.3 to 15v running good
if on the charge system failed. (causing battery discharge)
if after charging a battery it will not crank car, its a bad battery (jumps ok)

96 Monte carlo z34 won't crank over unless I jump


Sounds like a problem with the key switch, probably the security system. You may only have power to the fuel pump when the engine is cranking.
Is the security light on or flashing ?

Why won't my 2012 Suzuki Grand Vitara start?


ill answer for NO ELECTRICAL POWER :
sure and is easy with any DMM meter, got one? any $20 DMM.
my guess;1
engine will not crank
dash lamps out.
head lights out. dead.
post systems of electrical system , all parts that work and those that dont work, and problem is easy.
cleaned battery terminals.
tried borrowed battery that reads, 12.6vdc ? (charged is 12.6)
2012 that is in warranty car.... ?
my guess on 2012
jumping a car, that is battery jump starting.
a battery can short, and no jump start on earth will start shorted battery in car. but does lay down some big sparks, or burns up cheap walmart cables.
if the car will not crank, say just that, my starter motor will not crank
jump started from live running other car.
if true then make sure headlights work , if they dont work fix that first.
HL must always work, even keys in pocket.
best is to put a fully charged battery in the car, jump starting can cause
surges that can damage sensitive electronic$$$, do jumps as a desperate measure,
with a charged battery,
1: Head lights work, no fix that , use voltmeter
2: cranks robustly.
no , wiggle shifter lever, (on A/T cars the park switch blocks cranking) On M/T the clutch blocks cranking.
with any dMM
measure battery voltage before crank and during.
12.6v good. reseted.
cranking.
0 to 10v bad (weak battery or shorted starter motor)
11 and above good. and must crank, if not , starter is bad.
to prove starter is bad, check voltage at starter solenoid coil wire lug.
it must be at 11v cranking , below 8v it chatters, and fails.
if at 0v cranking this lug that means the Key start line is failing.
A/T switch not closes, or bad ignition switch.

Onan generator microquiet 4000


Check the pickup tube in the vehicle, the fuel pump is suspect. If you check the fuel pump pressure and it is ok, then try installing a test check valve between the fuel delivery hose to the generator. If it solves the problem the pump is losing it's prime internally, so replace the fuel pump.

I jumped car off it crunk on its own fora day,then batt went dead again,this time it won't jump off. It wants to crank but won't turn over.


not sure what you said but.
seems the battery is discharging,? 12.6v is fully charged,
own a voltmeter?
try a good loaned battery , does it start the car,?
i think you meant?
i can jumper cable start my car at any time. (off another running car)
but after running my car, the battery discharges and it will not crank at all. right?
this means ,the charging system on your car is bad.
if the starter cranks great, then the engine is flooded or is in great need of a tune up (sparkplugs etc)
if flooded try the super secret in the op guide, crank with throttle wide open , this magic trick cuts all fuel injection allowing the flooding
to purge away, and eventual starting.
my guess 2 is the car wont start, so you crank the battery flat
you jumper start it and it runs. (luck)
then day 2, same deal cranks ok but wont start.. ever tune up the engine?
