2005 Sierra won't start (after flexplate replacement)

[MileHiSierra]

Good Sunday to you all,

I'm in a panic and could use some advice.

I just replaced the flexplate, dropped transmission, transfer case, etc. Got it all back together, turn the key and nothing. no clicking, just dash lights and the stupid buzzer.

Ive got a 2005 Sierra SLE 2500HD, 6.0 w/ 4L80E 4x4.

Battery is fine,(even tried a Jump just in case)

Was running fine till flexplate took a dump.

I'm very frustrated and need it tomorrow. Any help would be greatly appreciated.

Thanks.

Check your starter connections. If they are clean and tight, are you getting voltage to the starter when you attempt to crank the pickup?

I just pulled the starter again to check connections. Is there a way I can jump the solinoid to see if it is working.? I am home alone today, so I've got no help.

GM grounds alot of stuff on the back of the heads... make sure you reconnected that if you disconnected it...

I'll pull the starter and see if I can bench test it. Checked wiring again. and again. Can't find anything loose or disconnected.

Thanks for the help!! It is appriciated!

Make sure you didn't break a wire

Bench tested the starter.... All is good. Will go back and check wiring one or two more times.

Rechecked the wiring again. The nuetral safety switch decided to go south, just really bad timing. Things are back to norm.

Thank you all for you help.
