Need help car cranks but wont start

was the replaced ignition flashed to the vehicle

Hi
Is it a coded key that your using ? If so it might need recoding
Regards Nick

car wont crank or car wont start? I would say your battery cables are bad,, acid gets in from battery and erodes internal cable parts... need a Meter to check it out.. put the meter on battery while someone tries to start it, if the voltage drops from 13.5 to 10 then it is trying to turn over, I always have the new starters tester before I leave a store, they are remanufactured in Malaysa and they use old parts in most of them..

Need more information. Could be fuel pump, fuel filter, crank sensor, cam sensor. Starter??

To clarify - the engine cranks but won't start, or the engine does not crank ?
What have you checked so far ?

I am a self emplyed mechanic, if a motor cranks but does not start, that is not a starter, you need to see if you have gas or spark . is there a buzzing in the gas tank when you turn the key. if so then you have gas. now you needto see if you have spark. need 2 people to do this . pull a spark plug wire and stick a screw drive in the boot and crank the motor please stand back,and look for spark. if you have spark. then you need a crank position sensor thank you ted

Sensors may not help you. Define "wont start". cranks? wont crank? cranks but wont run? Check engine light on with key on?

The crank sensor wires may be oil soaked, try moving them a little and see if it will start. It's beside the crank pulley on the passenger side. Got my lincoln started that way.

1. Fuel pump.

2. Alternator.

But you need to go for a scan. But it is a fuel system error thgat has made other things malfunction.

when you replace crank sensor the crank sensor is going have to be reprogram or relearn before car will crank.
