1987 ford bronco 2 turns over wont ignite loose distributor

Check your Fuel Pressure.

crank position sensor and or ignition module

Check to see if the spark plugs are getting voltage. Check your distributor and rotor and make sure the distributor cap is not cracked, and the rotor is making contact. You can use an inductive timing light or use a spark plug connected to one of the plug wires to and ground the base of the plug using a jumper cable (do not touch the plug when cranking). When cranking you should see a spark. If you do not it could be the coil or electronic ignition. If you see sparks then you need to check the fuel pump pressure.

I hope help you (remember rated this help) Good luck.

Belt, remove the the front plastic cover which covers the Timing Belt to see if the belt is stripped of teeth, same as the old Ford Pinto motor.. remove dist cap and watch rotor rotation, see if it is spinning... Ignition Modules are a major issue with those in that year also... check module also...

there is a two piece control module and pick up in distributor you could replace these or try a used distributor

have te ignition module and stator been replaced? that is the common cause of this, and yes the engine being out of time can cause this stall out, when you time the engine remember you must remove the timing shorting bar at the distributor connector to the TFI ignition module or the timing will be severely retarded

When your facing the front of your bronco looking into engine compartment, on left hand side in sequence is 1, 2, 3 front to back. on right hand side it's 4,5,6, front to back. The distributor rotates clockwise. On the top of the distributor, is 1-4-2-5-3-6 starting at the little mark on the cap or TDC. Hope that helped.

The first part of your question must be verified first. Is the engine still running or is it possably the starter motor that will not disengage?
