Hi and thank you for reading my question. I have a 2014 f150. I have been reading online about fuse 27 ( fuel pump ) fuse blowing . ford has a Service Bulletin out on this (TSB 15-0137 ) and a relocation kit for the fuse . ( EL3Z-14293-A ) My f150 is running fine. My question is do you think I should put in the fuse relocation kit in my truck just as preventive maintenance ? or just let it alone, if it's not broke dont fix it ?
I wouldn't do it as a "preventative" and I'll tell you why.
The TSB is specific as not all 2009-2014 F-150 vehicles are affected by the issue.
Pay attention to the questions in the TSB labeled "1" and "2".
If your answer is "NO" to these 2 questions, leave it alone.
So, if you aren't throwing codes, and after pulling the fuse, you examine the fuse terminal and see no signs of excessive heat (melted plastic) at the fuse terminal, leave it alone.
Here's why. To relocate the fuse you have to pull the power distribution box. You have to flip it upside down and open it. Then you have to dig around and move every wire in that harness to fish out the 2 wires going to that fuse. Then you have to cut them and splice them.
You're opening a dangerous can of worms. You could inadvertently loosen connections to other fuses in the process.
Moreover, you have to make 2 splices and I don't care how good you are with heat shrink tubing, you'll be inviting corrosion to get into that wiring and cause a REAL issue where you didn't have one in that wiring circuit.
In this case, "If it ain't broke, don't fix it" would be prudent advice.
SERVICE PROCEDURE
1. Does this vehicle exhibit a crank no-start, loss of RPM and/or a MIL illuminated with DTCs P0230, P025A, P0627,U0109, P0201, P0202, P0203, P0204, P0205, P0206, P0207 and/or P0208?
a. Yes - proceed to Step 2.
b. No - this article does not apply. Refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual for normaldiagnostics.
2. Does the battery junction box (BJB) exhibit signs of excessive heat at fuse F27 (20 amp) terminal location?
a. Yes - install a BJB fuse F27 relocation kit. Refer to the instructions in the kit.
b. No - this article does not apply. Refer to the PC/ED manual for normal diagnostics.
I am of the opinion that you should do it as a preventative measure, I was totally unaware of the issue until I was traveling and had a no start on my 2014 F150 XLT, Since I am pretty good at trouble shooting I immediately checked the fuel rail for pressure and had none, I went to fuse 27 to check for power no power at fuse I pulled the fuse to see if it was blown which it was not but noticed that the terminals looked burnt upon further investigation I noticed where the housing was melted. I jumped the FP Relay to get to my destination and then put a temporary fuse holder on to get me home. instead of using the kit i ordered the Terminal and crimped it to the fuse 27 wire in the fuse block and moved it to an open maxi fuse location
Thank you for everyones in put to this problem. it is nice to see people are willing to give advice on vehicle problems
Your fuse isn't blowing so leave it until it does.
I would rather have a fuse that might blow, than some cobbled together wiring. Now that you are aware of the issue, just carry spare fuses cross the bridge IF you get to it.
I just re-read the TSB, and there is absolutely no mention of blown fuses. Only heat generation.
I would get it fixed since I don’t want to get stranded on the road side if it goes out.
A fuel pump fuse going out on you will make for a bad day. I would definitely get the TSB implemented on your truck so you don’t have to worry about it.
