Mike2JZ Posted May 3, 2020 Share Posted May 3, 2020 I doubt your Link is dead. The battery and oil light do not run through the Link, so if they are not working then perhaps you have another issue going on. Does the starter motor crank if you try to start the car?

absz Posted May 3, 2020 Share Posted May 3, 2020 I'll start by rechecking the 10amp Ecu fuse located in drivers footwell. but with that blown the car should still crank over? Quote Link to comment Share on other sites More sharing options...
mellonman Posted May 4, 2020 Share Posted May 4, 2020 I would start with undoing what ever you did while you was testing , if it was just testing and no changes made revisit the points you tested and check good connections and that all pins are still in plugs correctly. Also check to see if you have power at the ecu. If not then check the wiring diagrams on the home page in the repair manuals Quote Link to comment Share on other sites More sharing options...
cookieboy Posted May 4, 2020 Author Share Posted May 4, 2020 Afternoon All right ive checked the All the fuses none are blown that i can find the car does still crank ive took the loom back out to check if i missed a plug and i did not (2x grey ecu plugs and 1 Orange and 1 Grey in passenger footwell link have replied and gave me the pins to test to see if its getting power im going to do that now and ill report back shortly.

Swampy442 Posted May 4, 2020 Share Posted May 4, 2020 Thats oil level not temp. Sounds like a power issue somewhere Quote Link to comment Share on other sites More sharing options...
cookieboy Posted May 4, 2020 Author Share Posted May 4, 2020 Thats oil level not temp. Sounds like a power issue somewhere Why do we have two oil lights? one red on the left panel and this orange one on the right panel? Also Issue is no resolved problem was the orange connector plug i now have power and i am able to access the ecu again. Quote Link to comment Share on other sites More sharing options...

One is oil pressure, the other is oil level Quote Link to comment Share on other sites More sharing options...
