91 Ford Explorer xlt 4.0 LITER

Ford ExplorerI have this 1992 Ford Explorer XLT 4.0L and no crank no start I’ve done every thing I can think but listen to this just for kicks I hook up a jumper wire and hook it up to the EEC to a solid red wire and it started several times and then it wood not start after that. What now I don’t want to give up I know it works good Explorer.
