1991 Ford E-150 Question: Ignition Start problem
Check to see you have power at the Yellow wire at the ignition switch( it comes from the fuse link/battery power), the brown /pink wire should be live only when starter position is engaged, red/light green is live in the run position, if any of this is not so the switch is bad and needs to be replaced. Alldata is probably the best source for information. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online - patrick mannion
Your problem sounds more mechanical than electrical. When you turn the key past the "Run" position to the "Start" position, the ignition lock cylinder moves a rod that actuates the ignition switch. Because there is no "spring back", I would suspect a bad switch or a mechanical disconnect/breakage between the lock cylinder and the switch. - Precision Automotive Repair
This sounds as if the vehicle was staring before the key cylinder replacement so i suggest to recheck the cylinder installation and connections to the switch. - DR.RECO
