Starter not working

Jump started my lawn tractor yesterday with the Buick, no problems. Got back into car a few hours later, engaged key absolutley nothing. No clicking no sound at all. Battery is fully charged, can jumper solenoid on starter, starter engages. Checked fuses in car and under hood all appear ok. Disconnected battery to see if that would help, nothing. While under car noticed starter was dirty and oily, worth taking connections apart? This is driving me crazy, please help.

Roy, THe year on my Lesabre should be 1992 not 1989 sorry for typo.I can get a tester yes. What should I test for. Please get back to me asap driving me nuts. Another thing is when I turn the key to the start position the security light constantly blinks. The security light has been on always for the past six months with no ill effects. Just don't understand why everyhing was fine now nothing.

Locksmith told me it is a broken wire on security system, need to replace lock cylinder an wiring.

I thought I had a bad battery. They checked it out and said it had 12 volts but the cranking amps were really low. So I got a brand new one with 1000 cranking amps, put it in, and absolutely nothing! I checked all the fuses in the panel, and all appear fine. I have a problem that I thought may have partially caused the no start one. The shift rod that has a little round end that fits over a nipple would come off on occasion. The shift in the car would just be really loose when this happened, and all I needed to do was open the hood and pop in back on. I tried a tie wire to hold in down, and that worked for a year or so, but then it started popping off the nipple again. Would this have anything to do with it not even making a sound when I turn the ignition key? I mean, the new battery can't be it, and it's installed properly. Of course the lights and everything else are strong. Is there an emergency swith in the trunk or somewhere that I need to reset? Please help! Thank you very much, Ray

I don't know! You're the mechanic not me. I was hoping you would say, yep, just open the trunk and you'll see a switch and yada yada, or, let me know if the shifting rod can casue a misconnection somewhere in the starting system.

Could jump staring my lawn tractor drawing down the battery have caused the security sytem to lockout the ignition?

my battery is reading around 12v. I had my altenator tested at autozone. They told me it was good? When I try to start the car, I hear the starter engage and if I hold it in start the starter tires down. No crank. Could this be an ignition switch. A few days ago the isturment cluster was blowing fuses then popped now wont come on. The battery lights been on also. Could all these problems be realated?
