I had a small slow start problem a week ago. I since changed the fuel filter and now I have a MAJOR slow/no start problem. With a gage I can not get pressure over 12psi when cranking. If I bleed a bit of fuel from the pressure port I can get it to start after a lot of cranking and bleeding. Once it is running I get about 20psi of pressure. This seems really low!! It drive OK, but seems pretty sluggish. Once I turn it off the pressure just falls off immediately.
It seems like a priming issue but while running I only have the 20psi which seems low. Is this the check valve going out in the pump? I am wondering since I changed filters if I didn't just kill it somehow. What do you guys think?? I don't want to pull the tank if I am chancing the wrong thing.
I think I am going to change the filter one more time. It is much easier than the pump and doesn't cost much just to be sure.
One question though, does the fuel filter on the 01 (remote mounted in axle housing) have a built in reguator inside the filter. It has 3 connections on it. 1 from the pump, one to the engine, and one back to the tank. I'm really questioning this since it got bad right when I changed the filter.
Yes, the 01's have the regulator in the fuel filter. My book says that if your pressure doesn't reach normal range, 44.2-54.2 PSI, then check for restrictions, and then replace the pump. If it is higher then specified, then replace the regulator/filter.
I'm having a opposite problem, Its fine while driving, but after sitting, it looses all pressure.
