Question about 1989 Ford Escort
Remove the plugs from the head. Insert into the coil wires. Make sure
they are properly earthed on the engine. Crank the motor and check for
spark at each of the plugs.
Refer to the diagram. Cylinders are connected as shown on the diagram in blue. 1 goes to cylinder 1(sparkplug furthest from coil pack), 2 to 2, 3 to 3 and 4 to 4(closets to coil pack).
To test the coil pack use a digital volt meter. Measure resistance between coil towers for coil 1(marked 1 in red on diagram) Value should be between 12000 and 14500 ohm. Do the same for coil towers 2.
Measure resistance between I and C1. If the measurement is more than 5 ohm the coil is defective. Do the same for I to C2.
Measuring voltage at I(Ignition start/run) to ground should be 10V.
I is connected to the 15A engine fuse. The radio interference capacitor is connected between this line and earth at the coil. Disconnect it to see if it cures the problem.
C1 and C2 connect to the powertrain control module.
Bear in mind that aftermarket coil wires may cause problems with misfiring, so see if you cant find an OEM coil wire to replace the broken one before replacing anything else.
