Fuel pump relay can't be serviced, have to replace the BJB.
BJB can't be serviced, have to replace the harness.
Harness can't be serviced, none in stock.
I hate to sound like an old fogey, but the new stuff is all garbage. In the three years I've been working out of this service truck, it has accrued almost nine months of total downtime.
Yes. But not all at once. Lots of small repairs, and last year it was out over 5 months waiting on an engine because although it survived the first turbo failure, it didn't survive the second.
This fiasco began with a shorted out fuel pump (lots of fun with a full tank, sloped ground, and a crushed rock "floor" to work on), then turned into troubleshooting wiring, then tracking down a relay socket, and of course various other stupid bullshit like driving many miles for incorrect or inadequate parts. Had the truck down for only most of the week this time.
I get ripped on for driving a 32-year-old service truck, and occasionally I privately wonder if I should get a newer one. Thanks for reminding me that new stuff breaks too. In the past 3 years my "old junk" has had exactly 10 hours of unscheduled downtime
They truly don’t care, I’ve had an obd1 car running on 2 out of 6 cyl not throwing a check engine light before. Thing only popped on when the ECU decided to fry itself.
Yeah, about 10 years ago, a friend's ~5yo Ram 3500 got broken into and the stock radio was pried out of the dash and the connected harness was ripped out. It was down for several months while searching for a body harness. Insurance was about to total the truck when one was found at the last minute. A 5 year old diesel truck was almost totaled because a meth head stole a stock radio. Ridiculous.
that sounds about right for my shitbox ford as well. currently up on stands with every single rear end alignment bolt permanently fused to its respective bushing
If you have a CDJR dealer you deal with you can buy recall part number CSZDV621AA that’s a complete wiring kit for doing exactly this and they’re right about 20 bucks
Dang, thanks for the tip. Never would have expected Stellantis of all companies to come through with this. Looks like I might be buying some genuine Mopar parts for off-label use
There is a kit to do this per nhtsa
https://static.nhtsa.gov/odi/rcl/2014/RCRIT-14V530-6412.pdf
Part number-CBP4P541AB
It was a recall on a few vehicles,but can be used on damn near any Chrysler jeep etc.
Think this is bad for relays? Try a 1990 LeBaron convertible. The panel is up high under the dash on the left side so the steering column is in the way.
Supposedly the top of the panel can be yanked on to hinge the panel down for "easier" access. Uhh. No. I could not get it loose.
There's about 20 relays packed as tight as the stones of an Ancient Mayan wall. Four of them for the headlights. To swap one in the middle I had to wiggle out one at the bottom then continue a column upwards until reaching the suspect one.
Yup, a bag of relays and fuses lived in the trunk.
Chrysler successfully topped the Mustang II fusebox in difficulty of access. MII fusebox is on the firewall up above and to the right of the column and pedal support. Lots of wiring harness and pokey metal in the way.
It's hilarious that OP is apologizing for not having the right fuse holder yet, and apparently plans to upgrade it- this is already better than 95% of upfitter wiring and a decent proportion of OEM wiring. Gonna give our trade a pat on the back here and say I'm very proud of how much pride y'all take in good, reliable wiring.
Not too shabby. Although you could have used a proper fuse holder.
I've done this many times. Like others have mentioned, Chrysler TIPMs have a few relays soldered on the board and it can only be serviced by replacing the TIPM. Chrysler does sell a kit (although, last time I tried to get one it was not available anymore) because the fuel pump relays either quit out or stay on.
The last time I did it was on a Kia Soul for the door locks. Same concept. Just soldered in a mini relay and tucked it behind the dash.

Is the vehicle in the OP this service truck that's been down for 9 months

The nice thing about OBD1 systems is that they aren't exactly programmed to give a fuck about much.
LOL, it has no PCM whatsoever. OBD-zero. You're right though, I have some OBD-1 vehicles too and they're not very fussy at all
They truly don’t care, I’ve had an obd1 car running on 2 out of 6 cyl not throwing a check engine light before. Thing only popped on when the ECU decided to fry itself.
Similar experiences here. If you ask me, OBD-1 struck a much better balance between "emissions compliance" and "alarm fatigue"

Well, it's looks about the same when chrysler relocated their fuel pump relay in the grand cherokees lol.

Chrysler products do that too. there are many posts online on how to bypass the TIPM since they built in the fuel pump relay.

> There's about 20 relays packed as tight as the stones of an Ancient Mayan wall. That's a fantastic collection of words
Nice job. Just make that shit work.

Perfect. Send that shit...
I bet with some soldering skills you could replace the relays with sockets for relays.
Ahh.... they are usually buried inside the modules. But yes, you could solder a new one on if you have the skills
Laughs in Chrysler TIPM fuel pump relay relocation.
Good hack, make it happen!
Was this their answer to the non weather sealed connectors corroding?
I like how they went to the trouble of using a water proof relay but then mounted it upside down lol
It is still waterproof at that angle. But once I got the BJB all bolted back in I did level it out.
Great job! Get some split loom tubing on there
Done that to many mid 2000s Ford f series. Shitty design imo
Did that in someone F250 a few years ago. 30 minute $10 fix.
17-19 6.7 powerstroke?
Is that a couple of crimp connectors and a zip tie because someone was too cheap to buy a fuse holder?
That's on order, but I need the truck up and running now.
