If you believe it is a fuel problem, have you checked your fuel pressure? If you don't have one, go buy yourself a decent fuel pressure gauge and see what pressure you have. It is a simple test and only takes a minute. It will either show that you have a problem or that your problem is likely elsewhere. Your pressure should be about 26psi.
If you don't have 26psi, first check your fuel filter and make sure it isn't restricting flow to the pump. Then check all fuel lines making sure that they are not collapsed or kinked. If you still can't get enough pressure, it may be a bad pump or a bad pressure regulator. Pinch off the return line momentarily and see if you can get enough pressure. If so, your pressure regulator is bad or needs to be adjusted (I don't know if they are adjustable on 1.7 but they are on 2.0) Otherwise it could be the pump. I hope this gives you some new ideas to look at. Hang in there and you will find what the problem is. |
