First post here. Got a 98 gs300 that quit on my dad. Within 30 minutes of parking, it wouldn’t start up again. Cranks no problem, fired up with starting fluid. No CEL before and still no current codes.
Here’s all I’ve done already:
checked all fuses and relays (swapped EFI relay)
replaced fuel pump (still doesn’t start with the pump being jumped)
I can confirm the fuel pump is running at key on with it jumped but again, still not firing at the injectors I assume
seems like the whole fuel system is shut down. I was thinking the immobilizer or anti theft but the security light turns off and stays off when inserted. There is only one master key. Battery is not dead in the car or key. Could the ECU be the issue? And if so is it possible for it to quit spontaneously like that? I was planning on testing power at pins on the ecu but I’m having trouble finding the info I need on what pins are what
I’ve searched through a lot of these posts without any avail unfortunately. Hopefully someone’s had the same issue as me
