After I start my car, I drive a few feet and it stalls and will not start again. Can anyone tell me what it might be?

This could be a few things but the most common thing that would cause this is a fuel issue. So we need to do two things, first check for codes to see if there is anything there.

Next is check the fuel pressure to see if that is the cause as I suspect it is.

Let's start with this and go from there. Thanks

I checked the fuel pressure and when I turned the key it showed over 50. Then I found out I wasn't getting any spark. Changed the ICM and the coil for #1 and #4 plugs. Still no spark. What else could be causing this?

Okay. The most common thing is the crank sensor. However, I attached the testing that we need to run through to track this down.

Here is a guide that gets into more detail about this issue:

Let's run through this testing and see what turns up. Clearly there are other things that can cause no spark but as I said the crank sensor is the most common but I would not guess at it and run through this test.
