I finally got my fuel pressure tested on my 89 xj. It's supposed to be at 31 psi but it's only running at 29 psi. Is two pounds enough to really make a difference??
Unfortunately I dont have a manual, but I wouldnt think 2psi would make that much of a difference.I would say no. Usually the pressure will have a + or - allowance. Does anyone have a manual that gives the proper pressure???
Sounds just like mine about 2 months ago. Ended up being my fuel pump. It was still working (technically) but it wasn't sending ENOUGH fuel to the engine, hence the hard starting. I could sit there for literatly 1 minute with the starter cranking and it still wouldn't start (*Note, I did not do this as I know it is very bad for the starter). But nonetheless I would definatly keep the fuel pump in mind as the possible trouble maker. HTH....Hard to start, have to crank the shit out of it, poor mileage, doesnt run well at all (see my numerous other posts)
