2000 Bravada starting issue
went out this morning and she wouldnt start. new battery, new alternator so those arent problem. pulled out relay for starter and there was a little 'fzzz' and then nothing. bought new relay and new starter(had old 1 tested and it was shot, new 1 tested fine) and replaced both but still no start. all the power comes on, just no crank when i turn key. used tester on wiring that goes into starter and the smaller wire only reads 0.03 when i touch it. plus, when i try the continuity, no beeps at all. any ideas? could the wiring all of a sudden be bad or is it more likely that i fried the ignition switch and if so, how easy is it to replace.

Re: 2000 Bravada starting issue
Does the starter relay, (in the underhood fuse panel) click when you turn the ignition switch to the START position? If it does, check the purple wire on the starter solenoid for battery voltage when the ignition is in the START position. Then post your results.

Re: 2000 Bravada starting issue
No volts on the purple wire or on the battery cable? (at the starter) If there is no voltage on the battery cable, and there is voltage at the battery, the fuse under the battery may be blown.

Re: 2000 Bravada starting issue
no volts on the positive cable at the starter. took it all apart today and pulled the fuse under the battery and it tested at .3 ohms. i was told thats fine. the battery cable i need is a long black cable going to my starter with a small red cable going from the positive terminal end to that fuse under the battery and the alt cable running fron THAT cable. oreillys doesnt carry them so i hafta go through a dealership, pay $100 and wait a day. i called a local shop and the guy there said 'ignition switch, $350'. also said it probably wasnt the battery cable. im leaning toward getting the cable and replacing it. are there ways to test if its my ignition switch? also, is it possible that the starter relay fuse port is shorted out? how do I test that? what setting on my meter?

Re: 2000 Bravada starting issue
The black wire runs from the battery positive terminal directly to the starter, there is no fuse in that circuit. Disconnect both battery terminals from the battery. Clean the battery and cable ends with a wire brush until they are shiny clean, (no corrosion). Disconnect the black wire from the starter, clean the cable end and starter connection and tighten it back up. Reconnect both battery terminals and tighten. Post your results.

Re: 2000 Bravada starting issue
If the black wire at the starter does not show battery voltage at all times, that's why the starter does not engage. Don't waste time or money on an ignition switch, or any other part, until the diagnosis is complete. After you cleaned the connections, did you have battery voltage on the black wire at the starter?
Does the purple wire show battery voltage at the starter when the ignition is in the START position?
