Ok I have 91 lumina just picked up, its z34 with the 3.4 dohc, problem I have is it has lots of spark, and when break fuel return line have or seem to have lots of preshure, yet will not start or even fire, but when I add fuel directly though plugs or though spray bottle into the thoughtal body it fires, and will run even ruffly as long as I keep sparying it in, so MY? Is what would cause me to have fuel at the fuel rack but nothing going into any cylenders?
was told ther was codes with the ignition control mod, but when I check it comes up clear no faults, and tested the modual and it seems to be working fine, lots of spark, so any ideas
