Cadillac Repair: Cad Deville 1989; 4.5L Will not always start, battery cables, couple problems

Question
Hello Autohelp,

I have a couple problems.  The main one is that at times the car will not start after I have driven it and stopped and come back to start it again.  It never happens first thing in the morning or after long shut downs, only after it has started and ran for awhile, like to the store and when I get back to the car it will not start.  We have wiggled and tightened the battery cables and I thought that was the problem and at times it seems to start after I do that.  When I turn the key the lights come on, but the starter will not and does not even try to turn over.  Also the service engine light has been on for awhile, after a mechanic tried to help adjust the engine when it was dying.  Since than this other problem of not starting has come up as well as the service engine light.  The positive wires coming into the battery were loose, so I tighten them up and it started for about 10 times and than last night it would not start again, yet it did start this morning?

Answer
I need to know what the CHECK ENGINE LIGHT CODE IS ?.

Most times with this type of fault it is the starter that is at fault. However it could be the battery. If you take the vehicle into most any auto parts store they will test your items for FREE.
