You need to be more specific. Will it crank, but not start? No cranking at all? Do you have spark, fuel when this happens?
it will. crank over it sparks good and blue fuel pump is working but when it wont start I can pull the plugs and they will be compleatly dry
Check for pulse at the injectors with a noid light when it wont start. Could be an ignition switch or VATS issue.
it has no pulse at all to the injectors the key is realty lose in the ignition I have to realty rifle with it to get it to turn could that be an isue?
absolutely. I would try replacing the lock cylinder and ignition switch.
how do you replase it and will it mess with my security when I do it
google the procedure. its been covered a thousand times.
ok I went out there and now I can't get it to not start one first crank it will start for just a second then die and the security light stays on the second time I crank it the light goes off and it fires right up and runs like a dream could that be the switch also?
it never fails its always the second crank to
ok I changed the switch and no difference :(
