2001 suburban wont turn overemg35 10-01-2009, 02:10 PM Was running fine last night, I parked it and when I went to start it this morning nothing. I can hear fuel pump or something turn on and the ignition fuse click but that's it. I charged the battery and later tried to jump it. Gage showed enough power and still nothing. Thinking it may be the starter, any ideas out there? Cusser 10-01-2009, 02:45 PM Try jiggling the gear switch, or try starting in neutral instead of park (if one can do that these days). There's a neutral safety switch on the transmission that's involved with this. Also, measure voltage across battery while you're trying to start it. If voltage hardly drops, means voltage isn't even getting to starter. If voltage drops below 9.6 volts, then the battery is bad. Without a voltmeter (you really need one), turn on the lights, try to start, see if they get really dim (which at least will tell you that voltage is trying to spin the starter. The ignition switch can be tested with a test light or voltmeter at the small connection at the starter, should have voltage EVERY TIME the switch is turned all the way over to the "start" position. This all assumes that the battery terminal connections are all clean. Jump-start attempts (successful: Yes/No) will also help determine if it's a bad battery issue. My experience with many vehicles is: 85% bad battery 10% bad connections, terminals, wiring, ignition switch 3% starter 2% other emg35 10-01-2009, 10:40 PM Jump start attempts didn't work but the car showed 14 volt when trying to jump start so I don't think it's a battery issue risleydc 10-02-2009, 02:09 AM My K2500 Suburban 8.1 had a bad crankshaft position sensor that caused the car to die while driving. It would not turnover (start) at the side of the road for several minutes. Then it would just start fine. Cheap fix FYI jdmccright 10-02-2009, 10:06 AM Tap the starter with a wrench or small hammer. Old starters can develop a "dead spot" where if it stops at the right position, the brushes don't make contact. Tapping it will help nudge it enough to restore contact. If this works, have the starter repaired or replaced. emg35 10-02-2009, 11:11 AM I have tapped on the starter but that hasn't worked. Where is the neutral safety switch and the ignition switch? Is there a way I can test them? vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
