Default Car not firing, what to check next?

Hey sc community. My 95 sc400 is not starting. I have replaced the fuel pump. Cam/ Crank sensors are good. I am getting fuel. I am not getting any spark. Open relay circuit is good...checked all fuses and relays. Any suggestions on what to check next? I'm considering changing the ecu. Any suggestions is appreciated. Thanks

Bought the car like this 2 weeks ago. To my knowledge car has been sitting for almost a year. Also....fuel pump ecu is working. Ignitors are also good.

might want to pull you ECU and check for blown capacitors. If ignitors are good how about your coils.

Also, a few years ago I pulled my ignitors to paint their holder / support when I plugged them back it the car would not start. I unplugged them (they were plugged in solid) then plugged them back in and the car fired right up.

Coils checked and they're good. Could a bad fuel filter prevent my car from firing? When the key is turned to ''on'' position the cel is on.

check the CEL code and see what you get. car needs air, fuel, and spark. so you've checked fuel i'm guessing? check spark, unplug each wire from the spark plug, stick a screwdriver in there and touch it to the frame, see if you're getting spark. if you're not then check ignition coils.

fuel filter could not do anything to the car, mine is original with 250k miles and my car runs fine, yes i will change it lol.

What about the rotor/distributor. Chance of both going bad at the same time is low but one an check for cracks and moisture.
