Fuel Pump Madness

[ddjo]

I replaced the fuel pump on my 01 Ranger 4x4 about 6 months ago and now it will not start. Replacement pump is a Delphi FG0873.
OBDII is showing the same code as before the replacement: P0232 (Fuel Pump Secondary Circuit High).

I expect the fuel pump to last longer than 6 months so I'm concerned there's an electrical issue that's causing the pump to burn out (i.e., always stay on).
Any ideas on how to test this theory?

Fuse looks fine and I've swapped relays to ensure the relay isn't the cause.
Inertia switch doesn't appear to have tripped either.

Thanks in advance!

Is the pump still under warrenty?

Part quality has been absolute shit recently. Id replace it again.

If your truck has a return style fuel system (not sure on an 01) then the pump running all the time wont burn it up anyways.

You can also unplug it and check for juice at the connector.

Im not sure on OBD II but on the older trucks a Bad ECM can kill the pump

Still under warranty. Ordered through Amazon and took convincing for them to honor the manufacturer warranty even though it's clearly written on their website.

I'm hesitant to replace it with yet another Delphi pump. Had luck with any other brand?
Motorcraft is obviously the default but it's $50 more. Question is whether it's worth the spend?

Did you replace just the pump or the whole sender?

Swapping the sender is way easier, but also way more expensive.

May be worth the effort to buy a nice Walbro pump and swap in into your sender. Cheaper then a sender and should last longer. AND, if you still have the original sending unit, you could swap the pump into that before you end pull the bed.

This is the same pump I have in my ranger, installed in the original sender.

99.9% of the time... the extra spent on a motorcraft part is well worth it.

I don't understand how a "bad" processor could damage a pump in any way.

There was an Autozone 1/4 mile from our dealership and we got a lot of customers who'd had repeat failures with their parts. We'd diag the problem and quote the repairs and they'd often say Autozones part was a lot cheaper. My reply was "but ours works". You get what you pay for if you're lucky.

The ECM grounded the pump if i understand correctly.

Years ago rusty #1 the fuel pump quit. I couldnt figure out why so i hot wired it into the key IIRC.

Fast forward 20 years i put that ECM in rusty #2 and the pump wouldnt run. Ran a code and got a fuel pump code. Switched to a different ECM it took off running. So i kinda 2+2 equaled 4 that one.

I just posted a thread related to this. I lost power to fuel pump.

The 30amp green maxi fuse had burned out. It looked good, but was bad.

I replaced in some new fuses and she fired right up.

If you have power to the fuel pump and still no go, then its probably a bunk pump.

I have had a lot of parts not last very long lately, even the good ones sometimes. Bosch alternator lasted me 300 miles.

Unless your alternator is bad fuel pump failure won't be voltage related

The computer grounds the Fuel Pump RELAY, not the pump itself

3rd party parts are less expensive because they are not tested, just sent out with a warranty, YOU are the quality control department

Motorcraft parts are way more expensive because they are tested, Ford requires it because in the long run it's cheaper for them to pay more for a part than to pay a dealer shop to swap out a defective part, under warranty

Because a fuel pump is a pain to swap out, I would pay the extra for Motorcraft brand, other easier to change parts, 3rd party all the way, lol

This is the same pump I have in my ranger, installed in the original sender.

Replaced the entire sender. Unfortunately, I already disposed of the old sender previous to the delphi one. Amazon wants the entire unit back so I'll need an entire sender.
Thanks for the suggestion/recommendation. Based on the other responses, I may invest in the motorcraft unit. RockAuto has it for $186 which is way less than what I can find elsewhere.

I looked at the fuse and it seemed fine (no breakage or burning). Worth the $10 to replace it and the relay just to be sure.

I picked up parts out at the Pickers yard. All kinds of stuff I couldn't name, a couple starters, a couple of alternators, boxes of stuff dirt cheap and likely better than new parts place stuff, all Motorcraft

2016, the OE pump on my 98 crapped out. Had Sears put in a new one, they used to have a shop a mile away. Anyhow, not had a lick of trouble with whatever brand pump they installed. Checked the fuel pressure last year, just for the heck-of-it. Still well into the acceptable range after six years and some 40,000 miles.

That's because you are a junkyard junkie
