We need to start with checking the basics.

First and foremost, we need to check the fuel pressure. Here is a guide that will help with this:

I suspect the oil pressure light is coming on because the engine is stalling and that is common.

So, let's focus on the fuel pressure and we can go from there.

Please run through this info and let us know what questions you have.
