What he said, and replacing the FPCU while trying to "milk a few more miles" out of a HUMMING pump will just kill another FPCU.maxnix wrote:Used FPCU should work (inspect carefully), but buy the fuel pump new or rehabilitate by texasoil's instructions.

FPCU usually don't go bad unless driven into the ground with a very bad fuel pump fo a long period of time.
Actually my stoplight bulb monitor squatted when I tried running the fuel pump straight to ground (bypassing fpcu).Q45tech wrote:It seems really hard for some to grasp the concept that electronic speed controls [and sensors] are always KILLED by defective WORN OUT mechanical devices.

Are you saying that I shouldn't try to get a used pump and used FPCM? My hope was that I could find a pump that wasn't humming, and a FPCM that wasn't fried and use those for now.Q45tech wrote:It seems really hard for some to grasp the concept that electronic speed controls [and sensors] are always KILLED by defective WORN OUT mechanical devices.
Is your FPCM in decent shape? I estimate that I drove my car for a month with the humming pump. The shop told me it was humming and wouldmaxnix wrote:Used FPCU should work (inspect carefully), but buy the fuel pump new or rehabilitate by texasoil's instructions.

My car is an early '94 (January). Are these '91 components the same as the early '94 ones? It sounds like you are vouching for these parts being in good working order, the mileage is low enough on them it apprears.defrag010 wrote:I have a GOOD fpcu and pump out of a 1991 Q that I'm parting out if anyone needs one. The pump was replaced when the car had 138K miles at "infiniti of memphis" (car came with records), and the car has 179k right now.
Thanks Drew. Please e-mail me purchase details and I'll compare with defrag's price to see which way to go. Again, [email protected].DrewQ45 wrote:FPCM is a solid-state electronic device. It's not burned or anything and will work fine. I'll glady refund if you have a problem with it.
It's $65 shipped. ThanksSeattleQ45 wrote:

Fuel pumps submerged in gasoline and fuel additives will look new externally forever! What you can't see is where the problem begins! I have used so many used pumps over the years with a lot of success but, when I get a used pump I always use the pump only from the FP assembly! I remove the pump from my old one and just swap pumps because my FP has had BG and ISO ran threw it so the pump is the only thing that most time needs to be replaced! If your not mechanically incline and are a heavy handed person don't do the swap and reverse wires or leave clamps lose or install parts backward! Replace fuel filter located on the bottom of pump assembly if it's dirty or dis-colored!defrag010 wrote:seattle, yeah I took the pump out and went "WOW this thing is CLEAN for so many miles"... then, when I took the glovebox and interior out, I foud all of the records the guy kept.
I'm waiting on a response from whoever [email protected] is about the fuel pump + a rad fan, so if he doesn't get it, then i will let you get it for 60$ shipped.
Sounds like breaker is buying the pump. Can I still get your FPCU? How shall I pay?DrewQ45 wrote:I'd buy defrag's pump and my control unit (newer) if I were you.
If the pump has only 40K on it, there should still be a lot of life left.
