Hardest part about changing the fuel pump is draining the fuel from the tank, you usually drink some. Then there’s all that road grime that falls in your face and down your shirt when you take the straps off…..not a fun job, but just about anyone can do it.
But, it could also be the fuel filter or pressure regulator, or ignition related. Pumps usually go out cold turkey. What year is it? Did the tech run it for codes? If it’s fuel related and the PCM stores fault codes, it’ll store a code for low fuel pressure. The F/A ratio will also be off if it’s a fuel starvation problem. This will show up in the exhaust sensor as whacked A/F ratio. Again, anther code. But if it’s fairly old, the codes will be erased each time the ignition is turned off.
Send me a PM with all the particulars and I’ll give you some ideas. No, I’m not a service tech. I’m just a hot rodder that likes to make things go fast.
