do all fuel pumps tick on a dx

hey all. i got an 85 dx lude the other week. its a 1.8 dual carb all oem. my charging system light came on the other day and sure enough it was the alternator. during my troubleshooting i noticed a ticking coming from under the drivers side quarter behind the door. upon investigating realized it was coming from the fuel pump assembly area. it sounds just like a relay tick. anyway while i had the alternator out i did some other work and started the car without an alternator and the ticking wasnt there. i got my alternator back and put it all back together and now it ticks again. if anyone has some insight on this it would be appreciated. if this is normal, great. if its not i obviously need to find out why. thanks

Re: do all fuel pumps tick on a dx

anyone with a second gen.... if its not supposed to do that i would like to know in case its damaging other electronics with a short or something. ive heard that older fuel pumps can be a bit noisy. with the fact that its a carbed motor could there be like a pressure sensor in the fuel line and a relay in the pump and when the pressure gets up it cuts out the pump?

Re: do all fuel pumps tick on a dx

so so. there is either ignition issues or fuel issues. for the most part its fine but when just cruzing at highway speed you can feel a pulsating in power.

To be honest, I can't remember if mine did or not...but then again mine was bad when I got the car...replaced it with a Holley in-line electric + Holley low-pressure FPR designed for carbs...

Re: do all fuel pumps tick on a dx

talked to a honda tech who was around in those days. yes they all tick. some quietly, some loudly. they were apparently all unique in that sense. as i suspected, because there isnt a return line to the tank, there is a fuel pressure sensor sorta that maintains a certain pressure. when reached, the pump cuts out. when it falls the pump cuts in. the ticking is the pump cutting in and out.

Re: do all fuel pumps tick on a dx

best is to convert to a facet red label carb fuel pump kills the noise and a slight bump in performance too :)
