Engine Performance problem
1998 Chevy Cheyenne V8 Two Wheel Drive Automatic 183k miles
New fuel filter & spark plugs Fuel tank pump/sending unit was replaced recently. Starts after 2 or 3 tries and runs well. starts well when hot. I have noticed that sometimes the fuel gauge sometimes has "ticks" in the needle. -- electrical? Do the injectors have a high pressure pump? What about a fuel pressure regulator? (I've used injector cleaner). The truck runs really well but it should start easier when cold. I've not found any obvious vacume leaks but I didn't really dig very deep. Thanks for any ideas.
