when i done this check the multi meter said that it was ok from what the arc was reading all this has been done and still the same results there is somthing else wrong with my car

then tell me this

where is the ecu located and how many main plugs go into it?

it is inside the car behind the glove box and there is 3-4

i am sorry but i am very frustrated with this car and hope to fix it soon
hope this is the correct answer

try this tsrm more inparticular being that it is for 87 not 90+ like the cygnus website

also post the results here so we can analyse them


p.s try to post all info in one post or edit your posts instead of having heaps of one sentence posts

i have learned a lot about this car in the last 5-6 months and it may not be as much as i should but im new to the turbo thing and well quiet frankly it kinda sucks

it does when you have a little bug like that to find

but the repair manual will narrow it down for you

i will try this in the morning and reply back with you .and thanks for all the help

edit: by the way nice build i had a n/a supra that i rolled and i loved that car it never gave me any problems like this one does

She knows what she is talking about guys :). And the real initials for tsrm is toyota service and repair manual, The real book is pretty expensive. But yeah its on thta cygnus site, and it is solid gold. Its helped me with at least 50 things so far. lol.
