I have a bad fuel pressure regulator. Our car (usually) starts, though occasionally it's a little grumpy about it or it takes a bit of cranking.
Changing the regulator takes a while for a Chevy Suburban. I'm a bit worried about the possibility of the fuel injectors going out at some point in the future as well, which would be super annoying to have to pay twice. Of course the difference between the regulator by itself and the spider injector is about $250-$300.
So aside from possibly using more/less gas than I should, what am I risking if I hold off changing the regulator until (if) the fuel injector goes out so I can just save up and then replace the whole kit & caboodle?
