So my scion tc won’t start it is turning over but I’m not getting a spark from spark plugs what should I do?
Check for a bad crank sensor.
If the computer doesn’t see crankshaft rotation, the computer see’s no reason to operate the fuel/ignition systems.
Other possibilities besides the crank sensor
- System voltage problem. Ask your shop to verify the battery measures about 12.6 volts before the first start of the day, then 13.5-15.5 immediately after starting the engine.
- IGM 2 Relay
- Camshaft position sensor (intake side)
- Camshaft position sensor (exhaust side)
- Wiring harness/grounds
- All the coil packs are faulty (seems unlikely)
you need to seriously consider replacing the crankshaft position sensor . . . even if there are no fault codes pointing to it
may I assume you’ve verified fuel pressure is correct?
