ive got a 85 f150 5.8 2wd and well the ignition cylinder broke i replaced it and lost all the electrical no lights no nothing the fuses are good the battery is brand new the cables are good i thought it might be the ignition switch but could that cause me to loose all of the electrical if anyone has any ideas on what it could be id really appreciate it

 

The problem could be isolated to the "new" cylinder?

Where did you get the replacement? Did you unhook or pull any wires from the harness? Double check your work?

Look for things out of the ordinary

 

i got the cylinder from autozone it was a direct factory replacement i didnt pull anywires out all i did was unhook the battery pop out the old cylinder and replace i then i hooked that battery back up

 

well i went and bought another lock cylinder and thats not the problem im pulling the dash off tommarow and checking all the wires again

 

The ignition switch is located on the top of the steering column about knee level. The switch is operated by a rod that runs down the top (outside) of the column down to the switch. There is a large connector on the switch. Check that the connector is still attached properly.

What was wrong with your cylinder?
Normally what breaks is the linkage that connects the cylinder to the rod. It's made from cheap 'pot' metal. Mine has broken 2X. Both times I was able to get new parts for about $15 from the dealer but it's been a few years.
Remove the lower plastic dash part and the plastic cover from around the column. Find the rod on top of the column and see if it moves when turning the key. If not the linkage is broken or possibly not assembled correctly. If broken you will be able to move the rod by hand or vise-grips and start the engine without turning the key... BTDT for weeks, (when nobody was looking), until I could fix it.

If the linkage parts are broken then you will have to pull the wheel and disassemble the upper column.

 

well the first lock cylinder the prong on the inside had broken off so i replaced it and the rod is connected i tried pushing it and still nothing happened one guy told me to take a wire from the + on the battey and connect it to the coil or the distriubtor cap then cross the solenoid with a screw driver and it should start well his exact words said do this and ....VROOOOOOM

 

FIXED well i feel very stupid but it was the battery i never checked it because it was brand new so i got it tested it didnt show a thing i got another one and she fired right up
