i recieved my obd-1 code scanner in the mail today and hooked it up to my 94 ranger.

for the last month, my CEL has been coming on for a minute, then goes off for a minute, then comes on again and repeats every couple minutes.

I got a code of 543.......

Code Reader Manual says.....Fuel Pump Secondary Circuit Fault.
Haynes manual says.......Fuel Pump Circuit Open; Battery to PCM.

Where and how do i start in correcting this known problem?

thanks

i really dont have a legitamite answer, but ill venture to guess that by what the haynes manual says, maybe a fuse is blown for the fuel pump or the pcm(powertrain control module?), so first thing i would do is check the fuse box or the haynes manual for fuel pump fixes?

kinda obvious i know but maybe it helps

 

all the fuses look good, thanks.
