Check out the crank position sensor, pull any applicable codes -- there may be stored failure codes. It could also be something like a head gasket issue causing compression problems, I've seen head gaskets go where you had to basically keep your foot to the floor just to keep the engine alive. Have you used a 'noid light to check the fuel injectors themselves for issues? If you are getting fuel pressure @ the schrader valve that doesn't necessarily mean you're getting good fuel into the engine.


The rail is full of gas, and the TPS is tested also, :(


That´s the problem, I´m not getting pulses on any injector, mi first thought is a bad ECU or cam sensor, any other idea?
