RE: [DMCForum] Re: !! - starting problem please back on track solved?



If the pump is jammed, try reversing the polarity just for a second or two.
The debris might get loosened up.  Reverse flush the pump with solvent or
gasoline to clean it out.

I got it from SpecialT.  I'll contact him and see.  I got one of his
tank hose filters as well and installed it before the pump so I
would be very surprised if debris got in it.  Well, this will hold
me off until I can afford changing out the accumulator (I have one
of those pesky hot start problems)  For this I hear going to get it
installed is the better choice.  I can't imagine climbing under the
car to try and get to the accumulator very easy.  Certainly not an
evening fix.
