No start after walbro install
Is there fuel at the rail? Do you have a fuel gauge? Really need to know if your fuel pressure is right...33 is stock..after market FPR..42 to 45 Psi. There is a o-ring in the fuel sending uint...the white thing that houses the fuel pump. Did you take the black plug with the connected ground wire to it out? If so the o-ring may not be seated. If it isn't you won't have pressure to start/run the car. re-track your work...take the sending uint back out and have a look at things. Good luck!
Thanks for the reply, I don't have a gauge, if I pull the return line at the rail it's dry. I took the black plug with the single ground wire out is there an o-ring that sits in that section? It might have fallen out, and I didn't know one belonged there. I really hope that's my problem. I thought the only seal was at the top of the pump.
Yes, just disconnect the small hose feeding back into the fuel pump module, and crank it.
I have had this happen several times to my Evo, as well as many cars when working as a GM technician.

Just to make sure, you have to seat the rubber grommet onto that connector and then insert back to the pump housing. You cannot leave the rubber grommet in the pump housing and then insert the connector. Again, this is not part of the actual pump and I think it is part of the clip at the bottom right of the pic.
That clip right below my thumb in the pic. I am not sure what the sensor does, but if removed you must make sure the rubber grommet is put onto the sensor first before reinserting. If this doesn't seal you can get fuel pressure, which was the OPS issue.
