i have a 94 sierra, about 2 days ago she started acting up and then quit,,finally got it going but my prob. is-- when i unplug the injecter on the left she will run,,if i take the plug from the right and put it on the left injecter it will run and vise versa, but will not run with both injects,,pluged in any help would be greatly appriciated,thx guys

 

First just get that fuel pressure tested.

 

a mechanic told me to unplug ect senser,,,the first i ever seen,I unpluged ect senser,ran great,,put a new one on running better then ever,,wat the ect has to do with the injecter, who knows, but runs fantastic thanks for ur reply
