Well I've been trying to start up my SR and I'm still not getting any spark. I've checked the coil packs based off of what the FSM says and they do have cont. between them. I also opened up the ECU to verify that it did not have any burned marks on it and there was NOTHING from both sides. I also replaced my CAS because I was not getting voltage through it. So I bought a working on( according to the guy I bought it.) and I still don't get spark. I checked the resistance on the ignitor and the numbers were all low so I'm assuming thats good. I also tried checking the resistance between the ECU and CAS plug from the harness. I wasn't too sure but should all the wires from the CAS lead back to the ECU? Only 2 were giving me resistance when I checked the pins to that wire. Please help I need to get this car started soon!

check all the fuses and relays. check to see if u get gas into the engine. take out the gasoline hose that goes to the intake and turn the key on to see if there is any gas comming out from the hose. from my experience no gas go to engine. u can crank it but it wont start. i found out that one of the relay near the battery has a bad connection so u going to have to try to taps them till u hear a buzzing noise which is gas going into engine. hope that help.
