Cranks but not starting

Hello Elva Ramos,

I am scratching my head pondering how an
ALTERNATOR could reach into the IGNITION...

and thinking it is likely more of a coincidence
rather than really a cause or effect...

But for ONE possibility...

If the "replaced" alternator is outputting
full wave alternating current (shorted diode)...

Simple enough to test...
DISCONNECT the alternator and attempt
to start the vehicle on BATTERY ALONE.

If that works RE-replace that ALTERNATOR

ELSE (move on)
Start looking for fire & fuel issues... or
blocked exhaust issues.

Check battery voltage when cranking the engine. It could be below 9 volts. It sounds like the voltage is jumping up when you stop cranking the engine.

do a proper diagnosis. You may have to methodically troubleshoot the issue. Now that everything has been adjusted and swapped, you may have to redo some of the work correctly to eliminate new problems. Newer cars are computer controlled and have many sensors that need to all work in order for the engine to run.

I think your mistaken. Your battery will lose cranking power as the temp drops. Warm battery may work just fine, untill it gets below freezing temps then the cranking amps are so low its sluggish. Buy a high cranking amp battery and you will be good as gold mate!

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

Charge up the battery so you can get the car started.Buy or borrow an electrical meter that will read volts DC. Start the car and read the voltage at the battery,you are now reading the alternator output, it MUST be over 12 volts and should be between 13.2 to 14.4 volts to charge the battery properly.If its not putting that out then I think its safe to say your alternator needs to be replaced.If it reads in that range then I would have the battery LOAD TESTED if that hasn't been done before.Just because it takes a charge doesn't mean it will hold a charge.A load test will rule this out. Failing this I think you need to take the car into a garage to have it checked over because if its not the above it could be electrical in nature and needs a mechanic to look at it. I'll keep my fingers crossed for you.Good luck

You say that the car will only turn over a little buit but not start. Is the car turning over and slowly dying out to nothing or is it just turning over and not starting?
