Default 99 C5 not starting/intermittent starting problem

This past week has been frustrating with my vette. I have a 1999 with a manual transmission. Sunday my car would not start so I jumped it and it started great. I took it to O'Reillys Auto Parts and had the battery tested and I was told it was a good battery; I was also told the starter was good. It then ran all day Sunday and Monday. Monday night I was driving home and my DIC read "Service ABS" about 10 min into driving. Shortly after that I got a "Low Voltage" message in my DIC and 10 secs later I had lost all power. I had no interior lights, exterior lights, power steering, abs, nothing. Luckily I rolled into a Dairy Queen parking lot where I got it jumped again and it started right up. 10 feet later it lost all power again.

The next day I went back to work on it. I tried jumping it and go nothing. I removed the battery and the alternator and took them to get tested. The alternator was bench tested twice and was good. The battery (800 CCA) read 620, then 1090, then 790, then 595. I replaced the battery thinking it was a bad cell. I cleaned the battery terminal connectors and installed the new battery and put my alternator back in. The car started and ran great.

Yesterday (Friday), I parked it at night and my E-Brake didn't catch so I went to start it again and got nothing. I jumped it and drove it home.

This morning, (Saturday) I could not start it in the morning, then 2 hours later I tried again and it started right up. I let it run for 10 min then shut it off and tried starting again and got nothing. It hasn't started since.

I read my codes
A0-LDCM B2252H, B2282H, B2284H
A1-RDCM B2283H, B2285H
B0-RFA U1255H, U1096H, U1064H, U1016H

I think most of the codes are a result of the battery dying/replacement. B2252 (Key Cylinder Switch Fault) is the one I think I should be worried about.

I went to relearn the VATS but my security light does not blink or turn on after the gauges have swept (it is on as the gauges are sweeping).

Thanks for the help!

most of those codes are low battery related, the switch code should show C for current if its malfunctioning..next time it doesn t start, pull codes immediately .. look for a C at the end ..god luck, these cars are notorious for electrical gremlins.. often its a poor ground point that causes the problem..

It is currently not starting but I am not getting any codes. I have heard about grounding issues and ignition switch problems. Tomorrow I was thinking about checking into the ignition switch. I wouldn't even know where to begin for the grounding issue

I found my problem, the negative stud on the terminal housing of the starter solenoid cracked and was dangling in space. Any suggestion on whether to just replace the solenoid or the entire starter?

There aren't any negative studs on the solenoid. The solenoid grounds thru starter housing which is bolted to the engine block. Perhaps it's the solenoid wire from the Ign. Sw. I think the wire is purple in color and #10 Gauge wire.

If your starter is dry, meaning no oil on it, then just replace the solenoid. But if it has oil dripping off it replace the whole starter. Oil will ruin the brushes and commutator of the starter.
For a good solenoid , if thats what you choose go with " Standard Ignition's Blue Streak High Temp Solenoid" Good Luck!!
