I replaced my air intake hose, told by a diagnostic and said there was a small leak. I got another diagnostic check and needed a fuel pump relay. I drive for five to ten minutes then the coolant light comes on then it starts shaking. Even done cut off. It will crank back up but still stalls.

Hi,

Is the engine coolant full? Does the temperature gauge indicate it is overheating?

As far as the fuel pump relay is concerned, it is in the battery junction box. I attached a pic of the box and highlighted the relay. If there is a different relay with the same part number, switch them to see if the problem stops. If there isn't one, here is a link that explains how to test a relay:

I have a question. By chance, does the check engine light stay on while the vehicle is running? If it does, has anyone checked for diagnostic trouble codes and told you what they are? If not, stop at a local parts store and have them scan the computer for you. Most do it free of charge. Have that done and let me know if codes are found.

Take care and let me know what you find.
