91 2.0
I recently bought a 91 Camry 2.0 the person I got it from did a ton of motor work to it New head, timing belt, distributor and igniter. The car has no spark. I have juice at the igniter plug, juice on the positive lug on the coil there's no juice on the pickup coil plug. I went to the junkyard today and bought a used ECM that did nothing either. My son found a kill switch someone had installed we disconnected all of that and taped the wires back up. As far as I can see everything that controls ignition has been changed all to no avail If someone can point me in the right direction before I lose all hope I'd really appreciate it. Sorry for the long post but I wanted to give the history of all that was done to the car.

Check for:
Cracks in ign coil.
Primary ign coil circuit resistance 0.38 - 0.46 ohm cold.
Secondary ign coil circuit resistance 7.7 - 10.4K ohm cold.
Distributor air gap for the two pickup coils 0.008+ inch.
Pickup coil resistance. Connection G1 (red) to G negative (black wire) 140-180 ohm. NE (white) to G negative same. With distributor wiring plug locking device oriented down. G minus is to the right of the vacant terminal in the plug. NE terminal is above G negative.
Ignition wire resistance. Should be 25K or less.
Spark plugs.
Battery voltage when ign on at black/orange wires going to the positive ign coil terminal and the igniter
Check wiring. There are 3 wires that go between the distributor and ECU, red, black, white (G1, G-, NE). The wiring is shielded and shielding grounded via the orange wire. There are 3 wires that go between the igniter and ECU, white, white/red (IGT, IGF). The black wire off the igniter goes to the tachometer and A/C Amp.
There is no way to test the igniter. If everything above is normal replace igniter.
