Did your check engine light come on while its running?Is it a lack of power or is missfiring real bad?

Yes the engine light is on. It is lack of power. This is what we have for a code 25 26 71 78 on the motor side and 62 on transmission side.

I would start with the code 78 fuel pump control circuit. Get a fuel pressure gauge lets see what the fuel pressure is with the engine running and shut off. Code 25 is lean air fuel mixture code 26 is rich air fuel mixture code 78 fuel pump control circuit.
