If you are going to work on newer cars you really need one. They are not very expensive, or I wouldn't have one 
That is how I found my fuel filter was partially blocked.

I'll tell ya what it is the starting and then stopping is it running off the fuel from the initial prime. It's either the fuel control module or you have a broken wire and the fuel pump isn't communicating with the pcm

Makes sense, fuel pressure gauge would help in the diagnosis.

FOUND THE PROBLEM! All by myself, I might add.... LOL! A couple of months back I paid the piper $1000 to have new plugs, coils, plugs and wires installed in my 2007 Expedition. And you all know that my car has been starting right up and then dying after 2 seconds. What was the problem?
Well, evidently these high priced mechanics did not get the rubber boot connecting the air cleaner system to the throttle body on correctly. So, the entire boot along with the hose clamp fell away from the throttle body and left me sucking air.... but not through the relevant sensors that would keep the car running! So NOW ya know! Thank you all for leading me in the right direction. While not perfect you all came damned close!
