1G-GTE PROBLEMS

[Boardman]

I put my GA70 1G-GTE supra in to a shop to get twin garret turbos put in it and when I when to pick it up it the injectors had no pulse.
Any ideas ?
how much boost can a stock 1G engine handle ?
And does any one have a ECU voltage pin out for the 1G ? :1zhelp:

At least I can give you the ECU Voltage Pinout for GA70 made Aug. 88 on. See pics.

Check the grounds to the ECU. No grounds = no pulse.

Yea its not that we were working it today and managed to get a pulse.
We think it is some thing to do with the ignition and or cam timing.
So if any of you peoples know the
- Firing order
- Cam timing
- top dead center
- Cylinder one
and do any of you peoples have a work shop manual (in english)

cyl #1 should be all the way up front.

As with typical toyota, there should be two marks in the cam gears.

Not sure about the firing order - I would think its just like the typical 7m.

Yep all that is good but the injector pulse keeps on droping voltage and stoping the person working on my car thinks its to do with ths dissy the sensor part that goes to the ecu so does any one know what the voltage out is ment to be :1zhelp:
