Hi Folks , really struggling with my wifes buggy . It has full power good grounds to chassis and motor. will not crank. It started the other day .She pulled into a mall (she noted on the way there driving , the trans select indicator said she was in park while driving and the speedo did not work) .Then it would not crank. I came there and went through as much as I could given the tols i had (boost cables , channel locks ,cresent wrench and flat screw driver.I confirmed good connections , jumped or crossed the starter and it cranked (but would not fire) hours later we came back it fired up and drove home (with no indicator or speedo) at home the next day i went , short drive parked and will not crank again. Starter relay is activating (feel it click) throttle body is making noise ) when trying . so i assume it has to be after the relay and before the starter somewhere . i would like a schematic on this but??? anybody have a similar iissue or have any ideas??? two years ago it had an issue with locks activating gauges not working , trans not shifting after a months (and spraying connections with realease all ) it cured itself

Sounds like a nuetral safety/trans range switch issue

if nuetral safety switch would the starter relay engage?

Are you getting power at the starter solenoid??

Voltmeter will be a necessary tool to figure this out

starter cranks when i cross batt power to switch wire at the starter , will not crank with key . Can The BCM create this symptom.Oil pressure speedo fuel gauge and rear paower gate , all quit as well . I am curious to know where the power goes after the relay

Sounds like a bad ground or sonething if all of that quit at same time... I will pull a wiring diagram tomorrow and see if i can help figure out what they all have in common....and where exactly is the power goes after the starter.... I am assuming this is a nnbs tahoe..

Have you changed the starter relay? Have you checked the 40A Starter Fuse?

Some of the other functions you lost are common to the B+ Bus.
