The truck ran fine for about two weeks then one day i was driving it down the road and it just died it did not suptter or make a sound, we have changed to oil , oil filter, spark plug, new gas, fuel pump and if you spray charb and choke cleaner it will run but only as long as you are spraying the charb and choke cleaner then it dies. Do you have any ideas to what might be wrong

IF it runs on starting fluid, you have spark. THerefore, you are not getting gas. Can you hear the pump run for a few seconds when you first turn the key on? IF so, have you checked the injectors to see if they are getting power?

Let me know.

We need to check two things. First, since the pump runs, we need to make sure it is producing enough pressure. You will need a fuel pressure gauge to check it. Most parts stores will lend or rent them to you. Here is a how to for checking that:

If the pressure is good, you will need to check for power to the fuel injectors. You will need a noid light. Most parts stores will lend or rent the tools you need for both processes. When you get to checking for power to the injectors, let me know so I can explaine what you need to look for.
