Fuel pump that'll last more than a year?
I replaced my in tank fuel pump in my 91 Bronco 302 last summer, and it seems to have died again.
It seems to prime, but then nothing. Engine cranks, but no start. Does this thing have two pumps? if so, maybe it's the second one is bad this time.
Sorry, it happened last night, and it got dark, so I didn't get a chance to look at it.
In my (and others I know) experience, many aftermarket pumps just don't last. I think that one was from Napa, which I've generally had decent luck with. as a rule, I stay away from Autozone for any parts I don't want to replace again anytime soon.
I don't care about a lifetime warranty. I just don't want to have to change it out every year or two. Chances are I'm going to keep this gas hog for a while.
I know Walbro makes a quality pump. Is there a chain store that sells them? I can't wait for mail order. What about Bosch? Should I go to the Ford dealer? The original lasted 90,000 miles, although I know many Ford parts sold over the counter aren't the same as what gets put on on the assembly line.
Any other brands you recommend?

It doesn't sound like the fuel pump to me. A failed fuel pump wouldn't even turn on for the two seconds after the key is turned to the run position. You can ground the fuel pump diagnostic wire to force the relay on, which would supply power to the fuel pump. This would tell you if the pump is working or not, but testing the fuel flow and pressure would be the next step. I would also pull codes from the computer to see if it is reporting any problems that can point you in the right direction.
I have had a NAPA in-tank pump in my truck for almost 100,000 miles now and it is still going strong. The factory pump failed due to infrequent use by the previous owner and the resulting rust build-up inside the tank.

OK... It doesn't appear to be the pump. I hooked my fuel ressure tester up and it pumps up to 40psi fine.
Pulled codes... A couple about the EGR not closing all the way or something, but nothing that would seem to make it not start.
Got the timing light out, and there is no spark... Looks like it might be the TFI module.
Should the TFI throw a code? I didn't see a listing for it in my code readers book.
Wish I could edit the title of this thread now...

OK... Even thought the TFI module tested bad, the coil ended up being bad too. Replaced it, and it runs again...
Thanks FTE!
On a side note, I was pretty concerned, because I couldn't see the oil pump drive shaft. Should it be below the little hole the distributor drops into? I seem to remember on past engines it sticking up slightly. Maybe those were my 2.3's. I could see a lot of dried up oil sludge... I think it's time for some seafoam.
After much time stressing, I dropped the dizzy in, and started it up. Listening for death noises. Ran for 15 minutes, without any, so I assume the oil pump was working.

It is a hex rod that goes into the bottom of the dizzy. It must have been in there or it would have let you know by now!!

I've also seen those oil pump driveshafts stay in the oil pump when the distributor is pulled. So don't sweat it. IF you aren't hearing any death noises or low oil pressure just let it ride.

There is supposed to be a small clip toward the top of the oil pump driveshaft that keeps it in the oil pump when you pull the distributor. You can't see it outside. Otherwise there is a risk of you pulling the distributor out, the driveshaft comes with it, then falls back out and misses the pump...into the pan it goes. It's about as fun as dropping a bolt in your intake.
