Fuel Pump Control Module Needed (I'm a moron)

[Q451990]

After advising people here to change their fuel pumps when they start to hum, I didn't follow my own advice! Actually, as usual, I had planned on replacing the pump in "Q1" this week. Apparently it needed it last week (or several months ago).

Luckily I didn't have intermittant problems, or a failure while driving... the car just wouldn't start on Monday. I checked and the fuel line didn't feel like it was pressurizing, no hum from the trunk when I turned the key to the "on" position, and then I found two fried components on the board. Interestingly enough, the connector and board are perfect except around those two transistors. In previous posts I gathered that the board damage is usually with the connector where it solders to the board. The only problem I noticed prior to the failure was a little bit of a hard start the morning before... Glad it didn't leave me stranded with clients in the car on Saturday!

Anyway, does anyone have an extra FPCU sitting in their garage that they'd like to sell me? I visited two salvage yards (no one over the phone even knows what I'm talking about) but they were already removed. I wonder how many used working modules die when someone plugs them in to a bad pump?

Just for reference, this one was installed at 88,705 miles on 2/25/1997 and the mileage is now 198,754 so a little over 110K. I didn't realize it had been that long until i looked it up just now . The car has had regular filter changes - but a lot of fill-ups at below "E" until a couple of years ago when Dennis mentioned that the fuel cools the pump.

Anyway... let the flogging begin... and hopefully someone has one of these things?

Well, it looks like Squeefoo's module is toast too. He checked it tonight and it has the same problem as mine. I replaced the pump today and borrowed the module from "Q2" - works great! Now it's just kind of like that story in Greek Mythology with the sisters that share one eye... Back "Q2" into garage, remove module, put in "Q1" - yadda, yadda, yadda...

Anyone else have one of these in their garage?

Thanks,

Heath

I found one in a junk yard today - finally! It was the 4th yard I visited (with one Q each) and it finally had that part. It's a burg. on burg. 91 or 92 that's relatively intact with 138K. The roof had major damage, maybe a rollover? Interior in fairly good shape, most everything was there. Someone had the fuel pump halfway out, but they never removed the package tray or rear seats, so I bet they couldn't get it out and gave up...

Anyway - got it for $50 and the board looked great! No evidence of overheating and the car had only been there a month or two, so it hadn't had time to get any moisture damage.

For anyone else out there browsing the junk yards - if you see a FPCU and can snag it for a decent price, do it! It surprises me how many cars had no modules but the pump was still there - I wonder how many people buy the module - plug it in to their bad pump, and fry it too!

As far as Q1 - it's a world of difference. Car starts easier, runs better, especially at a load, etc. I think I may have been suffering from marginal fuel pressure for a while. I'll never let a fuel pump go over 80-85K again!
