FJ60 stalling question (1 Viewer)

[NeverGiveUpYota]

Yep! That's right! One of the many reasons she's a Pearl! I bought it with 87K miles, one owner, who I'm pretty sure kept her garaged all the time. Haven't had to do much other than just wear and tear stuff. Biggest thing I think I've had to do was replace the starter (and was the original starter). Gotta love these trucks! Now I have about 106K miles. Was my daily driver for the first couple of years. Now she just gets to hang out and look good.

That was the real extent of my first truck. It was dead in the driveway, bought a starter used for $50, installed it and started right up. The guy I was dating then (2011) couldn’t stop talking about how cool it was at a Halloween party we went to afterward.
Well like I said, if you need help, feel free to email.

Ok, so I double checked my wiring. Definitely hear a click when i attach my jumper wires. It will idle with both jumper wires connected to the ICS, but not great. Definitely better when it is grounded at the carb. Had a vac hose off as well (prob from taking the air filter cover off and on). Any problem with leaving it grounded to the carb? Seems to run fine now, but idling a little low, around 500-700 rpm. Seems like it will only occasionally die if the idle falls below 500. Idles a little higher after the engine has warmed up. I looked into increasing the idle, but seems like a little bit of a complicated process and want to make sure it's done right. At least it seems to be running 98% of the time lol.

I ran my truck grounded to carb for almost a year and it fixed the same issues you are describing in this thread. There are some drawbacks to running long term grounded to the carb. By grounding to the carb like that you may get the truck to idle, but effectively bypass what the ECU does. I think this system was put in place to close the ICS and lean out the mix on deceleration. By grounding at the carb you effectively hold the ICS open as long as the key is on, thus stopping this mix leanout. I think it allows unburned fuel to enter the exhaust on decel, which can cause issues, something like that. A Mudder smarter than me can detail that a bit more. Take a look at the link @morganism included here as it details a long but similar situation to yours (hopefully) ended by re-soldering the ECU PCB harness plug pins. I would suggest if not good with a soldering iron seeking out someone who knows how to solder through hole components on a PCB properly.

Or if you just want to not deal with it, and trade Pearl straight up for my '84 60 Series with a working ICS system, you let me know. Problem solved!!!

Slick offer.

Too good to pass up, right? Look I don't even really want her truck, but if it helps a fellow mudder (not to mention Texan) out, then its the right thing to do. I mean who wants to screw with pesky ICS systems, amIright? If I can make that problem go away then damnit thats what I'll do. I might not like it, but I'll do it. Its the only way this ICS thing will ever truly get sorted. They are super hard to get working right once they go. Its really prolly best if you just wash your hands of the whole thing and move on.

She is no doubt mulling the deal over right now. Just waiting on the PM.

In seriousness, she does have a Pearl of a truck based on what I can tell of its history. Super cool and good on you for keeping it running.

You'd have to pry the keys from my dead hands lol. That's my baby for sure! But nice try
Seriously tho, thanks for the info! I'll prob have someone that knows what they're doing solder the ECU for me, but at least she's running for now!

Good girl! Us cruiser chicks need to hang onto these trucks. Never give it up to a MAN!

At this point you might just needs spark plugs, cap and rotor, spark plug wires and time it. We can walk you through those simple items. Then if it still idles low we can help you find the screw and turn it out a half turn. Really ez stuff.

Hey cool cruisers of Texas might be in your neighborhood. I’ve never used them but they have an entire “tuneup kit” that includes everything I just mentioned plus for just over $200

@hbunting I’m in NE San Antonio and I am always happy to help out a Mudder. I’ve got some tools and an old FSM. If you’re still having trouble, PM me.
