420A 1998 Eclipse GS that lost spark Someone please help

John24rc · May 3, 2026

So I have a 1998 Eclipse GS that lost spark and rpm after head gasket and timing replacement.

I've replaced the ECU, cam and crank sensors, coil pack, ASD relay, cam and crank pigtails, coil pack pigtail. I have power to coil pack but no spark coming out.

Please help

If it lost rpm to the tach it sounds like the crank sensor is having problems. It could also be the connector to the crank sensor or the wiring to the connector itself

I've replaced crank sensor, pigtail, and checked continuity of all wires. All seems fine
