for reference, running ~75-80mph in my 1/2 busted truck I was pulling down 11-12mpg, which isnt so bad i guess, hope to see better once i get her dialed in and slow the hell down
-
on another topic, if you have an Android phone, download the "Torque" OBDII app and pick up one of these wifi/bluetooth OBDII scanners
allows you to pull/clear codes, monitor your OBDII data in real time, check status of lots of things on the truck, pretty nifty. after years of jumpin odb1 stuff with a paperclip and counting the flashes of the check engine light, this is quite an upgrade!!
-
also I want to track down a stock intake setup, this aftermarket chromed out intake pipe looks good and takes up less space, but it is LOUD as hell when you are stomping on the gas.
-
ya buddy, even had her up to 90mph on some of the long downhills building speed to climb up the next hill, fun stuff! not recommended for the feint of heart...
Ya was checking the fluid constantly, it smelled and seemed fine, which led me to believe the trans wasnt burning up clutches or anything, maybe wishful thinking... I also wasnt positive on where the trans lines should hook into the rad, I just hooked them up where they seemed to naturally lie.
Also doing some research I learned the Neutral start switch will send info to the ECU to let it know what gear the truck is in, aside from just handling the lock-out of starting outside of P/N, so will need to get that resolved as well, right now I just have it jumpered to disable it so I can still start the truck since it wont plug into the 3.0 trans. I assume I could order a NSS from a 96 T100 and it should bolt up to the trans and plug into the 3.4 harness and allow me to fix that issue. ALso learned the NSS controls the PNRD2L dash indicator lights that tell you what gear you are currently in... was wondering why mine was not working.
Also still need to get that trans temperature sender resolved... and the rear o2 sensor... and clean up the wiring dangling around in the cab... haha one day I will be done with this project!
thanks for the tip on the AC washers, when I jumped it I didnt even get a click, It worked fine before the swap, so just hoping its the washers spacing it too far out and I didnt somehow bust the compressor during the swap
-
oh also still havent figured out my AC, I tried jumping the AC compressor plug direct to 12V and it did not engage.
I think I may have put in too many of those small washers behind the AC clutch, I think it might be spaced too far out. How many washers did you use? I think I used 3, will need to take it back apart and remove 1 and try again.

getting that starter out is a friggin pain in the behind even without the exhaust blocking it, good luck!
good news! I made it asheville! 500 miles down on the motor swap!
bad news! transmission is acting up, slipping like hell on the 2-3 shift, sometimes getting stuck in 3rd/OD even at a stop. Cruises just fine down the highway in 3rd or 4th, but pulling over to get gas was quite the adventure...
Really started acting up after about 7 hours of straight driving, limped it into the walmart parking lot, thought I had roasted the trans and was going to have to get her towed the last 120 miles to Asheville
Slept in the Walmart that night, started her up the next morning and she was back in action. Oddly shifting perfectly! Drove her to asheville and she is now parked on the street in front of my friends place.
back story, I had a little bit of a 2-3 slip even with the original motor, might have pushed it over the edge with the additional power from the 3.4L
Doing a bit of research this AM it does seem like its possible the trans #2 solenoid is going bad, this controls the 2/3 shift and also will cause the trans to get stuck in 3rd/4th limp mode when coming to a stop. Looks like a fairly simple fix to swap out, $200 for all 3 solenoids, drop the pan, unbolt the old ones and swap in the new ones. Will give this fix a shot when I finally get to a place where I can work on the truck.
motor ran like a champ though, lots of power! Speeding in a Toyhome is an odd feeling, I was cruising 80mph most of the way. MPG was horrific, likely due to me hauling behind, having no rear o2 sensor, and the T/C never engaging on the trans. Even still.. was a great feeling being back on the road.
Saluda pass just outside of Asheville is a 4-mile 6% grade, truck held ~55mph up the whole way. Ran a little hotter than I like on the grade so will be investigating that a bit.
Great to be back in the mountains, 66F this AM, with a high of 80F! Ill take it!
-
oh and I was able to close the hood 100% with no cutting or trimming of any kind.
I might still trim out those interior hood supports as I am pretty sure it is pushing down on the intake manifold a bit which cant be good for it
-
also looks like i have a slow leak somewhere near the back of the motor/bellhousing. not sure if its oil or tranny fluid yet... not leaking fast enough to care, gonna go enjoy it some more first!
-
these are the instructions on bypassing the AC relay from Offroad solutions, seems fairly simple
-
Just got her back from the mechanics, much better!
they had to fab up all kinds of linkage to work around the blasted crossover and had to tack weld all the crap booger welds and holes the last shop left in my exhaust, but we are rollin now!
I did get my front o2 sensor installed in the old bung.I am not running the 2nd o2 sensor past the cat yet, shop didnt have the toyota bungs, i have a new bung on order.
only Throwing 2 codes now
P0710 - Transmission Fluid Temperature Sensor Circuit Malfunction
I see an extra plug hanging off the T100 transmission harness, looks like it might be for a trans temp sensor, which I am not finding a plug for on the 92 auto tranny.
P0125 - Insufficient Coolant Temperature for Closed Loop Fuel Control.
This one might be related to not having a rear o2 sensor installed yet, have a o2 simulator on the way. My temp does seem to be running a bit cool, but seems OK.
other than that, running great!! Planning to drive her up to North Carolina tomorrow, been stuck in driveways and inlaws guest rooms for far too long, the road calls!
I also need to fix my AC
-
hey ed! great news!!
On my front I am having exhaust and shifiting linkage woes, first exhaust shop did a horrible job, leaks like crazy. drove it 2.5 hours across the state to another shop where its at right now, they are working on re-working the linkage and fixing up the exhaust.
drove great across the state, even with no o2 sensors hooked up and leaking exhaust. held 75mph easy peasy with barely any throttle.
hopefully hear back from the shop today with an update.

She got no exhaust and I have to crawl under the truck to shift gears but she's back and running on her own 4 feet! Took her on a quick drive today, lots of torque! Think I am gonna like this...
-
got it figured out ed, i ended up getting a giant breaker bar to wedge on the alterantor and was able to get the belt to fit, then i modified the 3.0L bracket to have a longer slot for the bolt to tighten it on, got all my belts on and rad in, my shifitng linkage got taken apart when i dropped the exhaust in, so now i am trying to work that out, should hopefully be going on a test drive soon. good luck with the wiring!
-
i am still strugging with my alternator, not sure if this 96 t100 motor/91 truck combo is any different than normal if I am just crazy. the alt is jammed between the power steering banjo bolt and the block, i only have about 3/4 inch of play between the two, no belt seems to fit. I have tried about 5 different ones so far, the 40505 is close but no cigar, wont strech over the pulley and the next size up is just a little too big, too loose, doesnt seem to be a perfect fit with such a tight window of adjustment
-
Picked up the AC pulley today, mine came off a 93 grand Cherokee, fit like a glove and now the compressor is lined up, thanks for the help Ed!
heres the pulley still attached to the jeep 4.0

few more EWDs hidden in here, but you likely want to get the ones off TIS that match your trucks exactly

shes alive!!! im a damn idiot and didnt have my ECU plugged in properly, got it fixed up and she fired up right up on the first crank!
Its raining its behind off right now but Ill throw the radiator in her and post a vid of its sweet sweet rumble in the AM.So excited!!!

Well, I am almost ready to turn on the key, I am pretty excited and nervous about that.
Just have some wiring at the ECU left and then checking everything a couple more times.
JFYI, ECUs rarely fail.
good luck! hopefully you have less problems than I have run into after my first key turn lol

ya I agree with you there on the ECU hardly ever failing, I did buy this one for super cheap on ebay so maybe I got what I paid for....
I am tripling checking all my grounds now. -
Heres a thread where a guy got the vac cruise to work
https://www.yotatech.com/f160/how-your-cruise-control-set-up-282791/
-
I haven't thought about cruise yet, i know my 3.0 system was a vac controlled system, so might be a bit more complicated.
does your donor have the 3.4 cruise? might be easier to use that

got my fuel injector fixed, now having issues with spark. im not getting any Check Engine Lights on the dash even with the key just turned on in ACC/ON, have a feeling my ECU is shot or the wiring from the ECU isnt right. Have a call into Offroad Solutions to help me out, also went ahead and ordered another ECU off ebay just in case

$240 for 1 injector from the local dealer
$120 for 1 injector from online dealer

hey ed! long time no see, I battled that trans issue for a while, eventually dropped the pan and replaced all the shifting solenoids, problem went away!
then came back the next day....
started to dig back into it and noticed some of the wiring leading back to the trans had melted due to the exhaust heat, I started pulling apart the melted harness and found a myriad of wires that had melted their sheating off and were shorting each other out, I separated out each wire, cleaned them up, and then electrical taped them up. I will eventually go back and try to get some actually heatshrink on them.
Took her out on the road and she shifted like a dream!
have not been using the old girl very much lately, still need to fix her AC, get an actual neutral start switch installed instead of just having it jumped, and get the rear o2 sensor installed.
that being said, I have put ~2500 miles on her and she has been great, love the power!!!
MPG is still pretty disappointing, getting ~11-13, but I am flying down the highway at 75mph
will be interested to see if her MPG improves once I get the rear o2 sensor installed and get off these damn highways, backroads are calling my name, should be on the move again in Jan
