starting problems

[e30idiot]

I cant seem to get any spark.

Engine turns

New coil installed

Replaced the ecu

Plenty of gas

What should I try next?

Thanks

Check the spark sensor or sensors, since we have no idea of what car.
Please give the make of the car.

Check the main relay or the crank sensors.

The common causes of no spark when cranking the engine are no power to the DME (bad main relay or blown fusible link) or a lack of timing reference data to the DME (bad CPS).

crank position sensor... it tells the computer how fast the engine is turning and what cylinder is where. the computer needs that info to know when to turn "on" the coil (really it just opens the ground)
