2012 Fuel pump failure (Resolved)

Thats lucky man. We had the bed off of my buddies truck for the bamf relocation brackets for 12inch kings.... and we were looking at putting a different fuel pump in as hes super charged.... fuckin front of the tank is under the cab by literally the difference in length of the LB vs SB.

Good luck man! hope everything goes smooth. And worst case, put the good pump in, then get the URD coming and replace it.

 

heres the thread dude>https://www.tacomaworld.com/threads/diagnosing-a-fuel-leak.155730/#post-3140972

 

Thanks for all the suggestions guys! I just woke up and am going to be heading out to get the pump shortly then off to the races before my windtunnel of a neighborhood gets too windy!

 

SigSense: Obviously you know everything about union employees.My Bad. Non-union workers are so much better behaved.Slave labor will do that.

 

I run mine past the low fuel light it has 60K on it, my 97 had the original fuel pump at 265K shit happens I have no clue who made them never had to replace one. A little hint about running the tank low and over heating the pump the fuel runs right thru the pump motor and all if the engine is still running there is enough fuel to cool the pump when the engine stops so does the pump. Opening a fuel line and saying it has fuel does not cut it you need at least 35 PSI for the engine to run properly.

 

hey heads up all now I need some advice.my fuel tank started leaking again after replacing and sealing the sending unit seal to no avail so I need to replace with new tank. any tips on removal of tank on a GEN1 truck.i am probably getting a aftermarket tank since an oem will break the bank.any input or advice appreciated

 

Glad you recognize the facts as presented.

 

Easy guys, no need to bring on the because you have differing views on labour.

 

Job is done. I am now receiving fuel at the fuel rail. I still am in a no start condition however and am perplexed as to why. I tested the old pump once I took it out of the unit and indeed it was dead. Like dead as a doorknob. I even tried dropping it on the ground just to see if that would trigger it back to life. Nope. So apparently I am having multiple problems here. All EFI, and fuel related fuses are fine. Fuel pump is good now. More then good. I had my buddy turn the key to on and crank just for a split second to see if I was receiving fuel to the rail. Fuel just blasted everywhere. Lol.

It's just really weird. How could this damn thing just die as I am driving it so suddenly withoutany warning. I have no idea what the hell now.

 

Did you post this in the gen1 section?

 

Don't want to hijack the thread but it's interesting that every one of the stories comes from a conservative news source and only tells one side of the complete story. I wonder if non union workers doing the same thing would ever hit the news, guess not that's not sensational enough.

 

no didn't post in GEN1 but did an extensive search there not much info found this https://www.tacomaworld.com/threads/fuel-tank-match-2002-xtracab-4x4.363007/

 

A couple ideas - measure fuel pressure with a gauge - just to be sure.

Disconnect your battery cables for a few minutes, to reset the fuel trims - if it's been weak for a while, the fuel trims will be way off, causing very rich mixture now that you have good fuel pressure.

 

I have disconnected the battery multiple times to no avail. I hooked up a scanner to it and recovered a code P1604 Startability Malfunction.

Spark is present, strong. Fuel is present, strong. I really dont understand what the issue here is.

 

I pulled the tank on a '98 reg cab to replace the fuel pump. Did it by myself after emptying the tank with a siphon pump, so I think you'll be able to figure it out. Dropping it was easy, but I did have a little problem getting it back in. I can't remember what exactly the problem was, but it went back in with a lot of cussing and jimmyjacking around. If I can do it, you can do it.

 

As a final update to this thread from my end, I really took my time here and checked every last possible thing here. I checked for all fuel injectuion and fuel pump relays and related fuses both inside and outside the cab, all in functional operation. Fuel. Got that. Spark. Got that. Compression, yep got that too. Both upon entry and exit there is no blockage of the exhaust and intake ports. I checked the immobilizer to make sure it was not triggering while the vehicle was cranking, nope. Tried a different key, nope. Pulled a plug to make sure the engine was not flooded, plugs were in normal condition and the engine is not in a flooded state. Cleaned and checked MAF to make sure it was not the issue, nope. I am receiving voltage to it and am receiving 5 volts to it as well as reference voltage. Fuel injectors are receiving a 12.02 ms pulse so they are working. Coolant sensor is in good shape and reporting to ECM. Start signal being sent to ECM upon cranking which is good and normal. I am sincerely out of ideas here and have covered all basics. I am just abou ready to throw up my red flag and comdemn the ECM as the culprit in this no start drama. I am aware there is a TSB as of 2007 which states of a reflash to it. I am going to call the dealer tomorrow, get it towed there and have them deal with it as I am still under warranty. If the reflash does it, great, if not, then they will be footing the bill for a new ECM and a flash to match the immobilizer. As for now I am dealing with a 5,000lb paperweight, which I am not very happy about at all.

For the record. Battery is an AGM and the battery voltage was 12.3 after all this time attempting to crank it still. Voltage cranking is 11.07 which is still more then enough to get it going, so battery is not the issue here either.

 

I got rid of my '12 Tacoma after it
Leaked all the antifreeze out with only 20,000 miles on the truck. Dealer never could find where the leak was coming from so it never
Got fixed. Traded it in and haven't missed it since. My 2012 was a huge disappointment compared to my 95 Toyota. The 12 didn't deserve to even be called a Toyota in my opinion! Toyota isn't what they used to be in afraid, that's one of the reasons I left. I expected 1995 quality and reliability and got neither.

 

I must say, this is one of the major disappointments that I have never had even with my Pontiac GTO. And that thing was a flaming pile of shit. Not once have I ever had a computer hard fail on a vehicle like it has on this one. If it's just a case of a reflash then great, but if it is the computer entirely, then Toyota deserves a huge round of applause for reliability. Not even my Mitsubishi 3000GT with a known track record of computer blowing issues and infamous "left me stranded on the freeway or the open road" ever left me stranded like this thing has. And that junk had 189,000 miles!!

 

Are you sure some joker didn't shove something into your exhaust pipe to block it?

 

Dude. I already stated that I had plenty of free flow in the exhaust. Not only that. How could someone do that to the truck if it died suddenly while driving down the road? Lol that's not the issue whatsoever here.
