Hey guys, it's been a long time! Anyhow. Car wont start. Turns over, very random sputter once every 30 seconds cycle. I am attributing that to my evap purge valve being broken, but I could be wrong. Tried starting with pedal to floor, as well as pumping it. On diablosport tuner, INJ1F through to INJ8F all read no when car is off , key in on, and when turning over. Fuel pressure at fuel rail is at 42psi. Even if I take out the fuel pump relay it doesn't drop. Injectors read 12v with key on. Tried starting with each one unplugged, and a combo of two unplugged. What would cause my injectors not to fire? Crank position sensor? camshaft position sensor? Any thoughts?
