1995 GMC Yukon stalling out

Are you getting any codes?

It's a 95

Without any diagnostics, first 2 guesses are Idle Air Control or Fuel pressure regulator. There is a reset procedure for IAC.
Look here for manual-https://www.tahoeyukonforum.com/threads/helpful-links.131971/

Is OBD 1 OR 2? IIRC, you'll need to ground out 2 posts on the OBD connector. 1st you'll get a code 12(1 long flash, then 2 short flashes) then it'll start flashing the trouble codes, after all the codes it'll then flash a 12 again to let you know the trouble codes are done. Long glasses are 10, and short flashes are ones.

The OP hasn't been here since October 2020. Let this 'ol thread die a peaceful death, please.

I did get code 54 and I read it on the manual it's a faulty fuel pump relay going to get a relay to see if it fixes the starter issue. Will a faulty relay make my starter not start?
