I have 2000 ranger that turns over but don't start battery has full charge but has no spark i have power to coil pac help

 

Welcome to the forum

You should also include the Engine you have in the 2000 Ranger, 2.5l, 3.0l or 4.0l

When you turn on the key the CEL(check engine light) should come on, this means the Computer(PCM) has powered up, no CEL = no start
Computer is powered up by the PCM relay in engine fuse box

If CEL comes on then turn key to START and WATCH the CEL, it should go OFF when engine starts to turn, this means Computer is getting a good Timing Pulse from the Crank Sensor, no pulse means no spark and no fuel
Check Crank sensor plug in
Crank sensor is next to the crank pulley at the lower front of the engine, on passenger side, has a 2 or 3 wire plug in, these rarely fail, so long shot

 

Thank you for information on crank sensor but that is not it because cel does come on by the way its a 4.0 do you have any other ideas

 

Does CEL go off when cranking engine over, thats the test?
