I was driving down the freeway and all of a sudden my trucks engine stops. So I pull off to the side I try restarting it starts briefly but dies as soon as I give it gas. This happened about 3x and then it wouldn't start at all. I tow it home the next morning I try starting again but as soon as I give it gas it dies. Again this happened like 3 times and it won't start at all. I do hear a click in the engine compartment then it dies, I think the egr valve is making the clicking sound. My first guess was the fuel pump but I'm getting fuel to the fuel rails although I haven put a pressure tester on the fuel rails yet. Any suggestions? Thank for reading this

 

Welcome to the forum

You have a 2002 Ranger 4.0l 4x4, you should include that with questions

Yes, fuel pump reads like a good guess, although they usually don't quit when running, just don't start up with key on, like most electric motors do when they are failing

There really isn't anything else that would cause engine to stall when driving without turning on the CEL(check engine light) full time and set a code for the problem, which you don't mention, i.e. CEL is on now when engine is running

Rangers don't have a fuel pressure sensor, so fuel pump issues won't set a code
Spark issue would set a code, losing voltage would set a code
Crank sensor issue would set a code, crank sensor is actually the only sensor the computer needs to start and run the engine

You can do 50/50 test just to confirm fuel issue
Remove the air plenum(air tube) from intake manifold so you can spray gasoline or Quick Start(ether) into the engine
Have some one crank engine to see if it starts OK
If not spray some fuel in
If it starts then Spark is OK, so crank sensor is also OK
Manually open throttle a bit, if it starts to stall spray more fuel in to see if lack of fuel is why it won't REV up, if so then replace fuel pump assembly

There are two things on the fuel pump assembly that can cause this issue, the fuel pump of course...............
But there is also a fuel pressure regulator, if it were to stick open then there would be virtually no fuel pressure, there would be fuel but limited pressure so no REVing, and this could happen while driving, vs fuel pump stopping

If you have or can get an OBD2 reader you can "talk" with computer to see if its "sane" because this could also be a computer issue but there are no tests for these computers, its a replace and see if it works thing, lol

But my money would be on your first choice, fuel pump assembly

 

Would help to know at least what year it is....
