Car won't start. Engine turns, but won't crank. Sat for about six months before we bought it. When engine did run, ran well. No noises
Injectors are not functioning. Fuel pressure is good, but no signal to injectors. Ignition good. Can you suggest any possible problems? Replaced the crank shaft sensor.

injector gets it s signalfrom ignition. if this is a 4 cylinder check the dist as the reluctor cracks on these. so it won't fire. but scan for codes as well and what is psi of fuel pressure? what engine is it?

It's a 3.1 L engine. Codes came back "12...12..12.." No other codes. Meaning system ok or a no codes problem. Fuel pressure seems ok. How would you and where would u measure the psi?
The previous owner said that he had problems with the brake switch sticking and draining the battery. Changed it(brake switch) , fully charged battery, changed fuses....still same. Engine is cranking over but won't start....
The gas tank is full. It seems as though the spark plugs aren't getting fuel.

fuel pressure should be checked at the fuel rail an dit should be 41-47psi any lower than that and you have problems like no start etc. you can spray choke cleaner into the throttle body and if car starts that tells you it's a fuel problem. auto parts rent gauges to check pressure.
