I have replaced the fuel and air filter. Replaced fuel regulator. Gas cap. Just replaced the MAP sensor (that’s what the code said it was). Had trouble cranking it but when it did start, Running fine, put in gear cuts off. Help

I think you are in the ball park of what the issue is. I suspect this is a fuel issue but we need to test a couple things to prove that.

Here is a guide that will get us started:

Next we need to focus on the fuel pressure just to be sure this is the issue.

Let us know what you find with this and we can go from there. Thanks
