1999 GMC K1500 Suburban starts then stalls

Stepping on the gas doesnt make a difference. Only spraying starting fluid has done anything but it only runs for a second or two longer then dies again. Also we remove the maf sensor with no change.

Did you try the trouble shoot site, spider,no start? curious,do you have power at injectors, when cranking?

[MasonGriffis]

I did look through that site a little. It's pretty nice. I appreciate you showing me that. I have not tested the injectors. How would I do that? It does fire and run for a second so I thought the injectors were working

Go back to the site,98-99 pcm connector pinout charts,you will see the injector wire colors,they are the ground side of the injector from pcm,use test light on one of those wires with clamp of tester on positive battery,see if it pulses after it stalls,and remember, always seal the pierced insulation with rtv when done
