Her dead 99 escort

99 ford escort wagon 4 dr 4 cyl 74k approx miles with aftermarket remote starter about 30 months no prior problems. Car traveling at 55 and lost power on road. Mechanic cannot determine why no spark at coil/plugs. Battery good. Please help I miss my truck that she is driving for now.

Disconnect the remote starter system to see if it starts. Are there 12V at the coil pack? If not, start from there. If yes, could be coil.
