Scott-tt Posted July 16, 2022 Share Posted July 16, 2022 Does anybody know if mk1 gs300s have immobilizers engine fires up and runs sweet but shuts off after about 5 seconds. Im using the gs300 ecu non vvti 3 plug. I was under the impresion they were all non immobilized however from what Ive seen on the internet some 1uz non vvtis were immobilized just wondering if the 2jz was the same as that might explain the problem Im having Thanks Scott Link to comment Share on other sites More sharing options...
Swampy442 Posted July 16, 2022 Share Posted July 16, 2022 Have you pulled the error codes? If it was immobilised it wouldn't even start. Also thats a feature of the Mk2 GS, pretty sure the Mk1 wasn't immobilised through the ECU Link to comment Share on other sites More sharing options...
Scott-tt Posted July 21, 2022 Author Share Posted July 21, 2022 Thanks for replying swampy I've not pulled the codes yet I'll do that next. It did seem strange non vvti with an immobilizer it must be something else. I'll get to the bottom of it Link to comment Share on other sites More sharing options...
Swampy442 Posted July 21, 2022 Share Posted July 21, 2022 Id have a look at the fuel pump ECU. What to do, open the diagnostic port in the engine bay, bridge ports B+ and Fp, be careful the wire gets fooooking hot! If it runs the fuel pump ECU is dead Link to comment Share on other sites More sharing options...
