Bump! Anyone have an idea?

you have no fuel at your rail?

its either a fuel pressure problem or your entering limp mode. does your check engine light come on while this is happening?

hows your wires.. hows your spark plugs?

Its getting fuel to the rail, I don't know if its a fuel pressure issue though. That was my first thought.. but I don't have a gauge on the line so idk. What is limp mode?

Limp mode is when ur ecu retards ur timing and makes it run rich so you don't blow the motor mine was in limp mode just fixed it today my knock sensor wire broke had to rewire it but I was getting code 52
