My SC300 keeps dying
Some one help I’m all out of ideas of what can be wrong with my sc.
my sc keeps dying out every time I drive more than a couple seconds it just completely falls on its face what’s strange though is that it will stay on at idle no problem I originally thought it was a fule or spark issue so I replaced my fule pump checked if I had spark and I did so then I thought it could be my efi relay so I changed it but same problem I also checked the timing and it’s all fine so I’m all out of ideas someone please help😔

Although there is no real connection to your symptoms and mine, other than it is running and then dies, an incredibly common problem with these cars, that happened to me, is the fuel pump ECU going bad. You can test this by jumping the FP and B+ points on your OBD port.
If this clears the problem that should well confirm it and you will want to replace the ECU or hard wire bypass it with a relay. It is not a good idea to continue to operate it with the jumper, as the pump will continue to deliver fuel so long as the ignition is on, which can be dangerous, and even deadly in the right circumstances.
If this doesn't work, I'm out of ideas.
