Hi All. Have a 1992 XLT. Seems to not want to start at times, other times it will crank right up. Battery is good, plugs wires. I can turn the key and sometimes nothing at all happens, mostly though I'll here MAJOR clicking going on under there(hood). Im guessing the starter and or starter solenoid. Question is, how or is there a test to determine if these are the culprits? I followed the directions in the haynes manuel. Everything points to the solenoid, but Im not a great mechanic and would hate to buy this part all for nothing. Engine is brand new, but the starter has NEVER been replaced
