I have an 92 olds cutlass ciera 3.3 199k miles. It runs for a while, and then shuts down and won't start up for 2 hours. Plenty of fuel pressure(35-40) plenty of spark, but I removed the fuel injectors(cpi-6 injectors) and left them on the fuel rail and tried starting up the car, but no fuel came out. I sprayed starting fluid and it started up fine, but died after I stopped spraying. What controls the injectors? I would think the crankshaft position sensor, but that also controls the ignition.

I think the injectors are good since it wwill run but then stop, I would try a new fuel pump. I have had that problem with lots of vehicles the pump gave enough for a initial start and the engine would have a little bit of suction just enough to get it going for a few seconds then it would shut right off. Fuel pump always seamed to be the problem. If thats not the problem clean the injectors, if the injectors make a click type noise wiht engine on or cranking then they are good and getting proper electricity
