No Start 92

I Have A 92 Explorer And A Week Ago I've Be Experiencing No Start Problems The Alarm Will Only Come On If U Mess With The Battery Post But Still No Start I Had It Jumped By The Tow Guy I Made It Home Started It No Start And There She Sat Until I Had An Alternter Put On It Started Drove It Around A Bit Cut It Off No Start This Is Bugging Me The Car Is Still Good On Miles This No Start Is Driving Me Crazy....do Anyone Have And Advise Also Had The Starter Check Its Ok

after market alarm system a just truble remove starter wires from alarm.
and could be safty switch on transmition

does it try and turn over? does it make multable clicks or just a single click. I know now that the single click is the pos. battery cable that goes to the relay and down to the starter. I just got one for like $20 and it fixed that issue

My 96 is having a problem with starting, but it's not in the starting circuit at all. It's actually in the sensor mounted on the side of the tranny where the cable and linkage go though. The electrical plug on the back of the sensor is picking up mixed signals and causing a no-start situation, also, if I keep the plug securely pushed in, it will cause my starter to engage when I put it into park. Sounds wierd, I know, but if i unplug the unit, turn on the key, and bump the solenoid, it fires right up and runs as if nothin's wrong. Hope this helps...
