Truck starts but most of time dies immediately. I have no acceleration at pedal. Need help

 

Will it rev up in park?

 

No it does not

 

I have new fuel pump, new iac motor, new fuel pressure regulator, new battery

 

How old is the tuneup?

Have you pulled the plugs and read them?

How about the catalytic converter?

What do you mean by "no acceleration at pedal" if it will only run for a few seconds?
The common problems section at the top of the FAQ page might ring some bells for you as well.

 

If I push pedal down it does not rev at all..

 

ACtually if I press pedal down it does not rev and immediately stalls out.

 

Any codes?

 

42 is the only code just checked right now.. I had different codes but all the parts I just on cleared all of them even the 42. I believe it is auto shutdown . But will that cause it to not rev at Ll when pedal depressed? If so how do I fix it?
