I have a 1991 Eldo with that either doesn't start, if/when it does start; idles to the moon than levels off.

That's on start up.

When driving; car sometimes stumbles on acceleration or bucks and hesitates while cruising.

It has a complete tune up (spark plugs, wires, cap, rotor, NEW distributor, O2 sensors, etc.), new fuel pump, filter, pickup screen (in tank) and starter.

Throws an E19 code which comes back as a "shorted fuel pump circuit".

So my question is, where does the fuel pump circuit start and stop? I replaced the harness and wires in the tank when I dropped it to replace the pickup screen and pump. Visual inspection of the plug in harness leading to the tank looked good, the rest is inside the car.

Picking up from say, the firewall, what should I be expecting next?

Anyone know where I can get the schematics for this car?

Any time is appreciated.

Thanks guys.
