86 dl ea82 carb. I keep having problems with my fuel pump working intermittently. sometimes it will run fine then all of a sudden nothing. ive replaced the pump itself twice so I think that is eliminated as a suspect however im having troubles coming up with a possible cause other than a fuel pump relay which ive only found a little info on. so my question is: do these cars have relays for the pump? and if so where would they be located? does thios sound like a common problem? thanks in advance for any help

It's not a simple relay.

 

But there is a "control unit"

 

It's mounted up above the hood latch pull. 

 

Has 4 or 5 wires into it.

 

The yellow wire is tach signal wire, if this wire is not recieving the pulse from the coil, it will not power hte pump, or the solenoids on the carb.

 

The blue/black wire is 12v out to the pump......put a test light on it with the car running, and watch to see if  it stays consistent.

I cant seem to post a picture for some reason.... anyway what I found up there (and was trying to post a picture of) is 4 little cylinders that loosely resemble flasher modules. could it be one of those?

 

edit: let me post the picture

edit 2: after a little research ive come to the conclusion that those aren't it. I found a picture of the guts of it in another thread so now I have a general size of what it is but still cant find it. is it normally hidden? found it it was on the right side of the cockpit(?) under the dash also there was 6 wires to it
