Good afternoon,
My 91 Chrysler con'vt. ran great this morning and at lunch but when I went to drive home... nothing. It's got gas in the tank and cranks well. I sprayed a little starter fluid down the air intake and it fired up for a moment so I know the ignition works. I spent a few minutes seeing if I had power to the fuel pump and that looked like a problem but when I jumped 12V to the pump directly, still nothing.
I suspect the fuel filter has never been replaced. Would a fuel filter clog all of a sudden with no decrease in performance before hand? The manual indicates that there is a auto shut down relay which seems to be working since it feeds the ignition coil as well as the fuel pump. The manual also references a "safety shut down" relay without any additional info. Is this "safety" relay the same as the auto shut down relay?
An old Jeep I had did the same thing when the crank position sensor went bad but I would think that the fact that the Chrysler will try to run off of starter fluid would indicate that this sensor was OK. Does it feed the fuel system circuit in anyway?
Any other ideas as to what I should be looking for?
Any help would be much appreciated.
Thanks, Mitchell R. Brown
