Hello, Ford Escort wagon Lx 93 ,130,000 miles, 1.9 L sfi engine. Driving ok. but I'm parking back of my house, come back 5 minutes later and won't start.

ENGINEE CRANK NORMAL.
NO SPARK

Fuel pump ok. (hearing noise when turner on ign. key and test psi)
Code reader used and no fault codes, except for the pass test 111)
Fuses Ok. (Both blocks int. and ext.)
ECM relays OK.
Timing belt spin (Just uncover part of the plastic cover and look trhu the gap)
PARTS REPLACED.

1.Coil Pack.
2.-Ignition module
3.-ECM
4.-Crankshaft sensor.
5.-ECM Relay

Still have not spark on the spark plug wires and not spark on tap of coil.

Please help me because I tired of read the Chilton manual and looking for possible cause.

Thank you.

Sincerely


Jose

Check the voltage reference to the CPS-does it have a camshaft sensor. Check all your grounds from battery to PCM.

Do you have power going to the coil from the ignition switch

Suggested Repair

Check the crankshaft position sensor voltage reference, confirm whether a camshaft sensor is present, verify all grounds from the battery to the PCM, and confirm that the ignition switch is supplying power to the coil.

Conversation Summary

A 1993 Ford Escort wagon with a 1.9L engine cranks normally but will not start after a short stop because there is no spark at the coil or plug wires. Fuel pump operation, fuses, ECM relays, timing-belt movement, and a code reader were checked, with only a pass code 111 reported. The coil pack, ignition module, ECM, crankshaft sensor, and ECM relay were replaced without restoring spark. The expert recommends checking the CPS reference voltage, camshaft sensor, battery-to-PCM grounds, and ignition-switch power to the coil.
