Have problems turning over my 1979 ford 460 big block

wiring in ignition or batt cud be fault--the inline fuse as a factor--or igntion switch/key lock--if it was theft system-car should start after putting key to ON after 10min--may want to try unplugn computer for a few or havin it scanned

Any flashing lights on the overdrive button. Sounds like a messed up torque converter or a computer command to stay locked up randomly. It's just a clutch that uses fluid, but most now have a electrical controlled magnetic clutch to lock them up. If they are told (wrongly by the computer) they won't let go and will stall the motor, cause harsh shifts, etc. Diesels just won't stop with the power they make. Scan for codes.

Sounds like the actual ignition switch is bad.It's no longer keeping voltage "hot" to ignition. Replace ignition switch

Your cylinders 1-4 passenger side,5-8 drivers side. Firing order is 15426378, looking at engine #1 is at 1 o'clock position, and order goes counter clockwise. The timing varies from year to year - call Ford w/your eng. # for exact timing. To get you in the ballpark,12 degrees BTDc if you have a vac guage, connect to a vac source on intake, crank motor up turn distributor until you get highest vac reading, then back off 3 lbs of vac.

I believe only another 460 motor.

look in where it goes in there should be a slot that should line up with the lock assembly you may have to turn it to the accessory position. if you feel you want any further help feel free to ask. Thank you for asking fixya.

Jump wires that would go to ignition, then jump wire from battery to solenoid to turn over.

Your not the only one with this problem. There is a piece in the lock known as the sidebar, that jams this lock up. Lock needs to be replaced. There are few people I just researched on Ebay that are selling this lock. Just do a search on Ebay Motors for Focus Ignition lock.

Tap the starter motor with a hammer it may be stuck.Sometimes it will jar it free.If that does not work remove it and have it tested.

get another ignition module sometimes they come broken and if it keeps happening there might be an electrical draw somewere
