ECU code 875k

[Frank Walian <walian@worldnet.att.net>]

Hello all,

    I have just placed a fuse in the fuel pump relay and have gotten the
following codes (4444, 1111). The reason for running the test is that I
noticed the fuel pump relay is clicking on and off once the car is warm
which makes the car sputter. When driving on the highway sometimes the
car will completely go dead, though if i turn the ignition switch on and
off while costing the car resumes properly.

    Before the car was running 5 min I got the 4444 good. As the car was
warmed up in the driveway, engine temp in the mid range of the gauge I
plugged the fuse back into the fuel pump relay. I got a 1111 though the
car seemed to idle fine and the relay didn't click. Any Ideas on what I
should do next ?

    Will an ECU from an 84 5ks work on my 87 5ks ??
