My 1MZ progress thread Options

No my thromostat gauge doesn't work right
Speedily works fine.

When mine acted kinda odd it was grounding related.
Did you put the 2 harness grounds back on the intake manifold then ground the block to the car?
What starter are you using?

[Smaay]

yes the 2 grounds are hooked up on the back of the engine, well one on teh back and one on the side of the IM. im using the 5S-FE starter, its the same as the 3S and 1MZ.

[kurt95gt]

Have you ground it out to the chassis yet

[ricochet1490]

multi-meter and start checking plugs.... GO

[Smaay]

ok just spent an hour on the phone with Doug, he is the man by the way.

we disconnected the wire on the 22 pin connector at pin 8 which was black with a grey band every inch and everything worked perfectly.

He thinks pin 8 is MRL which was sending the 12V to the starter trigger. we moved that wire to pin 7 which i think was STA, i cant remember.

now gotta figure out why when i turn on the key, my speedometer jumps to about 36MPH

1problem solve....few dozen to go

[Smaay]

Kurt, what did you use for water hoses to the heater core?

[kurt95gt]

I can't remember the size
It was same size as stock celica an I got 3 foot an cut it to lingth my self
I'll dig through my thread for the top rad hose for you too
It's got a part number the lower hose I used the stock v6 hose cut in half an the 2 old ends put together an a long hose with a 90 degree angle at one end

[kurt95gt]

Part number for top rad hose

[Smaay]

yeah i looked through your thread and saw this same picture, thanks. i have the radiator hoses taken care of, i need to do something for heater hoses

[kurt95gt]

All the rest of my lines are coolent hose from advance auto parts cut to length
It's the same size around as the stock 5s heater hose

[Smaay]

ok latest update. unplugged the speed sensor, same issue. needle jumps to ~36MPH and the Tach jumps to about 900 RPM (with the engine off) with the engine on the tach registers a signal but it does not match what my scan tool says.

the water temp gauge seems to read but its a little low. my tool says 180* F and the needle is about 1/4 way up.

it idles really low but i have a good theory why. im not getting and O2 STFT or LTFT information. just reading 0. i think its looking for O2 sensors.

im getting an airbag light, dont think that has any relation.

oops forgot to tell you the gauge that i swapped the V6 tach into was a good working gauge before.

i also have my original gauge cluster. i put that one back in and the MPH stays at 0 and so does the Tach with the engine running. give it some gas and there is no RPM signal at all

I've actually seen something like that. On my old blue project Celica, after I pulled the engine, specifically. Missing grounds caused some funky issues. When I turned the headlights on, suddenly my speedo showed I was going like 35 or 40 mph. When I turned the brights on, I was allegedly going 60. It was simply caused by engine grounds not being in place. When I dropped a 5S back in place and halfway bolted it back up, the weird issues went away.

I'm not doubting your grounds, just merely commenting. I'm willing to bet that the speedo is something simple. Still, I'd hate tracking it down. I wish you the best of luck!

[kurt95gt]

Yea your having some kind of grounding issue for sure
I've got 4 ground wires made out of ground cable for a 1600 watt amp
Try cleaning your grounds spots down to bare metal an add a couple more

[Smaay]

while i wont disagree i might be having a ground issue, when i swap clusters, the other speed gauge reads 0. i understand why the other tach reads 0 its struggling with the V6 tach signal

[Smaay]

i drove the car!!!!!!

i still have the GT throttle cable so i could only give it about 1/3 throttle. OMG this thing hauls ASS!!!!

bad news. the drivers axle pops out. it has the retaining ring on it but its still popping out.

[95CelicaST]

There should be two small grounds off the harness that runs under the intake manifold. This grounds the ECU. You should have a chassis ground off of the ACIS side of the intake manifold as well.

Glad to hear you got to drive it. Isn't it wonderful?

[kurt95gt]

Congrats!!!
Wait till you feel full throttle

[Smaay]

here are some update pics
