A fully charged 12 volt battery with engine not running, ignition off will read 12.6 volts at 100% charge.
12.4 volts at 75% charge.
12.2 volts at 50% charge.
12.0 volts at 25% charge.
check battery and alternator
check voltage of battery with multymeter,check water leval, specific gravitycheck if battery is too hot while cranking
as long as the cranking amps are the correct stye it will tell the cranking amps on the battery check your owners manual for the cranking amps for your van or call an auto parts store and ask them what size you need.
buy a battery load tester, or simply take your battery to a store that sells them and have them test you ccv's.
check grounds and check positive cable it may have a lot of resistance
you might need a stronger battery. check the cranking amps and upgrade.
Presumably you mean slow cranking. Check for weak battery or bad starter. If not slow cranking so much as long cranking time check for loss of fuel pressure overnight using fuel pressure gauge. If so, suspect leaking injector or possibly leaking regulator.
Is it cranking over at all??? Ceck for fuel preasure at the rails. also check for sparK
If the engine is cranking over fast(starter and battery ok) and it just won't start, it could be alot of things If the engine is cranking slowly, it could be the starter, the battery, or the alternator(not charging the battery) check your cables from the battery to the engine and the body... good luck d
Well the first thing i would check is the battery if the engine is not cranking, if it is cranking the you would probally check the ignition system[spark plugs, spark plug wires, ignition coil] next you would check the fuel lines/injectors/pressure.
Is it a problem of the battery goes dead or does it crank but not catch? If the battery is going dead over time perhaps you need to check the battery and/or alternator. If it's cranking but not starting, check the computer codes.
Check your cold cranking amp from battery. May need a larger battery with more amps. Also you need a tune up
