Need some help with 3.1? Anyone have GM knowledge??
 

What's up guys? Here's my problem, I just swapped out a 3.1 in a Sunbird GT, i hooked everything up (EVERYTHING). I'm not getting any gas in the motor (plugs are dry) I changed the fuel pump and injectors, NOTHING!! Gas to coming up to the motor (there's a check valve near the intake), just not going into the motor!! What the fack can it be????? Donor car was a 1990 Cav RS, mine ia a 92 Sunbird GT.
Someone please help!!!
Please PM only!!

Are you getting power at the injectors with the key on? (Test with a test light)

That would be a good start.

Check your grounds, get your hands on a wiring diagram/schematic if you can.

There is a ground that bolts to the transmission bellhouseing. When mine had broken off (2.8 same engine basicley) the injectors would not fire. Shoot some gas down the throttle body to see if she will start. Next step I would try switching ecms.

fuel pump relay

check the fuse for your fuel pump, usually located on the firewall on chevys

Im getting fuel to the injectors!!

check all the grounds and as said before wiring diagam would be a great help, you maybe getting gas up the injectors through the fuel rail but if theres a ground out for the injectors you'll get nothing coming out, let us know your outcome
