Our truck is a 98 Lmtv just replaced alternator with a new one. New batt all have 12.5 bolts. Still won’t start. Makes buzzing sound when switch is flipped and dash lights up but that’s it. Could it be a bad relay???? Was told possibly a bad tcm

The buzzer is probably the low air alarm right in front of the steering column.
Remove the cover to the power panel. You have 3 test points on the left. What voltage do you see at the 12 and 24v test points measured to the ground test point?

What does the voltage at the test points do when you turn on the main sw.

What lights, if any are lit on the dash display panel?
