How can I fix the starting issue. Won't crank more than 1 revolution....

Do you have fuel pressure and spark to the plugs ?

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.

Sounds like your solenoid is going bad... easy fix..

wont crank or wont start.??
no car starts , if it cant crank. (unless push starter (M/T magic)
that is not a trans sensor its the PRN switch.
ill answer for, wont CRANK !
it wont crank even with a good battery (charged) or jump started.
1: bad start
2: bad wires to same.
so hot wire the starter small wire, the key start line is tiny.
cranks. , starter good, no crank starter bad or cables bad.
if it cranks hot wired, then the key line is dead.
easy, huh?

bad battery or altenator

Are you saying the engine cranks but won't start, or the engine won't crank ?
If the engine does not crank, you would check for voltage at the starter, the neutral safety switch, and the key switch as well as the ground connections.

Sounds like the battery is dead. You can try a jump start and see if the car will start. If it does I wouldn't have any issue with replacing the battery and see what happens. You can also measure battery voltage with a voltmeter. You should see 12 volts with the key off, on, or cranking. If the battery voltage is not 12 volts than it is dead or low on charge. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

The body control module is the problem it is drawing the battery voltage down,and causing the lighting malfunction

Try to restore your pc to a date before the problem started. Just click on start, all programs, accessories, system tools, then system restore. choose a restore point before the issue started.

I have a saab 9.5 2000 2.3t, when I start my car it only crank but won\'t started. it is the alternator because I tried to jump it and it does the same thing, please help
