my 1uz mk3 project

thats how she sits right now with the new motor

you need a big bottle of castrol super clean.....

 

[taka21]

yea yea yea lol
it will look like that again in a week lol

 

[taka21]

ok so yesterday i got the fuel all sorted out (i think)
i bent the stock 7m hardline into place
its a little bigger than the uz banjo but the washers still seated properly.

todays chalenge is the brake booster and the wiring

 

[taka21]

crunch time
the car has to be driveable by saturday when it must be moved from its current location

i got the brake booster on its kinda wierd tho that pedal is hard as a rock and only moves like a half inch.
went out and had a custom fuel line made and got rid of that hardline(found that the banjo was too big)
all thats left is wiring


ok im a bit confused and im using the explanation on 1uzsupra.com.
on the fusebox side it says that the black wire in the eb2 connector is to run to the black and blue wire off the b1 connector
(which is on the other side of the car) im trying to figure out if that is the only wire that needs to be done that way or if the other two on the eb2 connector need to be run that far too

I'll see if I can get my fiend that wired my car up to call you.

Yeah, our wiring write-ups need to be merged and cleaned up with pin numbers and actual connector designations. Been on our todo list for almost two years now I actually started off by using Jake's information first but there are some differences due to the different years (Jake's is '89+ where mine and Viper's are '87 and '88 respectively).

There are two wires all of us ran from the engine bay connector (eb2?) into the interior to connect at the big yellow connector (b1?) behind the glove box. The one you mention above and then the black/orange wire (eb2?), run into interior to the big Black/Orange (add pin number) on the yellow connector.

The next longest runs after those two ended up being the extension of the alternator wires since the alternator on the 1uz is on the opposite side of where it was on the 7M.

^^^^ that was what I was trying to remember yesterday.....

 

[taka21]

ok so now i got an interesting question
if im only running the alternator what size belt do i need to run
all it has to hit is the crank, the alternator, and the tentioner pulley
i dont have the ps pump at the moment and need to get rolling today

Hopefully someone answered this for you already but if not, the next easiest thing to do, which I had to do, is to run a string (or small diameter vacuum hose) around the pulleys the way you would the belt, then take that into your closest parts store and they can cross reference to find the closest fitting belt. The belt I list in my BOM is for a car without the A/C pump and running the LS manual fan pulley instead of the hydraulic pump pulley for the hydraulic fan although this second one shouldn't make a difference since I think both pulleys are the same diameter.

 

[taka21]

OK now i have a bigger problem NO SPARK!!!!!!!!
im getting plenty of fuel and air but no spark
i pulled a plug wire and a plug and tried the old spark jump trick and nothing at all.
what did i miss???

Check the grounds and the conections at the coil packs and the trigger connections.

 

[taka21]

OK got its sorted out and SHES ALIIIIIIIIIIIIIVE!!!!!!!!!!!!!

and for some reason overheating within seconds of running
took the thermostat out and its still overheating
any ideas?

Yes, the stock temp gauge is a three wire gauge. Again, grounding issue. You'll have to refer to the MkIII TEWD for the colors and locations of the three wires or someone here can answer right away. I thought the same as well and was freaking out the first couple of times. I figured since the sensor body is grounded via the bridge that it wouldn't matter. It does. Congrats on getting it running!

 

[taka21]

got the girl up and running without a problem
temp gauge is acurate
now im actually overheating
lol it takes much longer than before but its now truly overheating even without the thermostat in her.
im about to go check the lines at the back of the motor and see if they are run right or not im kinda stumped
i only made it halfway home before it overheated and steam came out one of the coolant lines on the back of the motor

 

[taka21]

does anyone have a pic of the back of thier engine and where they routed their heater hoses

I just stumbled across this thread, from google. Taka get a new thermostat and put it in the motor, 1uz will over heat with no thermostat to control flow becouse they are a double bypass system. with out the thermostat the waterpump will pull water from the engine and pump it back into the engine and not pull water at all from the radiator. water lines at the rear of the motor almost dont matter as long as they are not leaking. also make sure all of the air is out of the motor. use the nut by the thermostat to get the last bit of air out of the motor.

 

[taka21]

ok ill drop the thermostat back in in the morning , and hopefully find that nut
i opened it a bit and didnt see where it went when the coolant shot out.

 

[taka21]

does anyone know the actual thread type that the nut is or where i can get a new one (just in case i cant find it.)

 

[taka21]

hey does anyone know how to pull codes on this late model engine
is it the same as doing it on the 7m with the diagnostic box on top of the motor wiring harness???
