I have a 1990 LS400 with what seems to be the notorious no start issue. We have spent a couple of hours pulling our hair out so far. The car will crank with no issue but it will not fire.
We have checked the following
Igniters are both working
Spark plug wires are all sending spark
Spark plugs are good
Fuel pump is turning on
We are getting fuel to the fuel rails
The car is in time
The trunk wiring looks good no wires look damaged
The car is only pulling one code 23 which is for the air temp sensor
We also tried spraying ether in the intake and it still did not start the car.
We have run out of ideals and have gone through countless no start post and have tried everything suggested but have had no success.
Another crank no start
