1988 escort gt no spark

Ok this thing has me confused, i bought it from a guy cause he couldn't figure it out, this is what he did, replaces the plugs, wires, cap , rotor, distributor, mass airflow sensor, computer. i went through a checked the
wiring, redid a couple wires i felt were suspicious, and i took the ignition module to autozone and it failed thier machined test, so i replaced it, and i still have no spark....it's the only thing wrong with the car! anyone have any ideas?

Does the cam turn? Hows the ignition pick up? Power to the coil? Power from the coil to the ignition module? Did you check the coil?

cam turns, ignition pickup? what do you mean? coil has power, had it tested and tested good. don't know how to test power from coil to ignition module, what wires do i test? same question for ignition pickup. i don't have any wiring diagrams.

is there any way to test the pickup coil? i tried connecting my multimeter to each of the 3 prongs, tried all possible configurations while spinning the distributor, got nothing.

The ignition pick up is a hall switch, it can not be tested with a ohm meter ( except for testing the ground to ground ). It is checked powered up and with a volt meter. You cheek for power in and check for a voltage state change on the signal wire to the ignition module. It is a on/off device. If the distributor has been changed, the pick up should be new. Also, it is not mass air flow per say. It has a Vane Air Flow meter, that real large aluminum box in the air intake. How do you know it has no spark? How did you test it? What else have you tested?

Shooting blind is not a good thing. You need a schematic, Haynes is not all that bad, and inexpensive available at your parts store. How was the coil tested for power? How many volts?

i used a spark tested to check for spark (go figure), the coil was tested for power at the connection goig into it, has 12 volts. coil itself was tested with ohm meter and tests in spec. had the ignition module tested and it came out bad, replaced it, no spark. last thought would be the pickup coil, they replaced the distributor but...who knows if they bought it new or not....
