On A Carbed EA81 the fuel pump is controled by the Fuel Pump Control Unit AKA the Rev Sensor

On carbed engines, I think the coil and the tach use the same signal..... since there's only two wires running from the disty.....

We don't have a FSM.

The FP on my '82 wouldn't run at all on it's stock wiring, and PO had it hot wired to a switch off the battery. I didn't like that idea, so....
I found a "key-on" hot wire under the hood, used that to power a relay. Ran hot wire from battery, thru a fuse, to the relay and then out to the FP hot feed. Works like a charm.
Didn't do it at first, but I did install a pressure switch on the oil pump. This switch closes it's contacts when it sees pressure. I then ran the ground wire for the FP relay thru this switch. No oil pressure = no FP running.
I can't find the receit for the switch, so I can't give you the number of it. I just told the counter guy what I was wanting to do, and he hooked me up with a switch.
By the way, my FP is way noisy too. Rattles something fierce. Don't know if it the original pump, or if it was swapped in when the EA-82 was swapped in. But it does it's job, so I can live with a bit of noise.

Most carbed 4wd EA81 cars have the FP relay just in front of the drivers door near the hood release. It's a black box with a 6 terminal connector. I can give you the pin-outs for this too.

Its my car man and that's not what I asked. Trust me I have gotten enough flack. I wasn't about to sell the car because its an ea81t and buy some other wagon when I had all this $ dumped into the tranny and clutch and drive shaft. Not to mention all the custom crap we have had to do. And all the time its taken! It angers me when people tell me how this angers them. I understand why your mad, but think of it this way. Who is going to want an ea81t wagon that failed emissions horribly, and every time u try to throw new parts at it, it just gets fussier and fussier?
Anyway that's my reasoning. As the car sits I have a little over $1600.00 into it. Back to the fuel pump. Thank you guys for all the advice. And sense this is my first wiring attempt ever, I am going to show it to Austin so I don't screw something up.
