So my 5.0 302 runs great, until it warms up. After it warms up it will stall out like it isn't getting fuel. Then wont run till it is cooled down. Did a a lot of reading and a bunch came up. So I started replacing parts.

Replaced:
Distributor
spark plugs and wires
Ignition Coil
fuel pump and tank
secondary fuel pump
coolant temp sensor.

Nothing fixed the problem!

The previous owner replaced the fuel pump and tank. Maybe he did something wrong?

What else could be a obvious problem?

 

Did you try running the codes

 

Check engine line isnt on.

 

You could still have stored codes.

 

How do you check the codes on something this old?
