No spark?

1990 corolla with no spark. Good coil good pick-up coil, power to the igniter with ignition on. Could it be a bad fuel injection relay?

IS THERE A way to ohm the ignitor for resistance. Could this be a grounding problem.

I have no spark. Replaced ignition switch, 2 different ecu's and 2 different distributor assmblies. Ignition coil is also new Every thing ohms out fine. Checked wiring for obvious problems. Car ran good a couple weeks ago but died and now have no spark. I noticed that the "check engine light" is not on during cranking or with the key in the on position. I also was checking the relays and noticed that the Main Engine Relay and the Efi/f/htr relay pulling in when you turn the key on but don't disengage when the key is turned off. This doesn't seem right. This is got we going nuts as I desperately need this car back on the road asap.
Thanks

Thanks for the guide and diagram I found the black wire not connecting so I ran a new wire and it fired right up ! Ya! I love this site

I have gotten new plugs wires and distributor. It tries to turn over but there is no spark coming out of it at all.

Hello I have a 1989 corolla sr5 309,000 miles. I will start at the beginning of the problems. Was about to drive to MI from TN, was on the interstate for thirty minutes and the car started overheating. I let it cool and added a little water I had to it. On the drive back home the temp was still higher than normal around 75-85% of gauge but was not overheating. Parked the car for two hours decided I needed a new thermostat and a coolant flush because of how rusty the coolant was. Drove the car 20 minutes to auto store, car was operating normally, not running hot was at normal temp. Flushed the coolant system and replaced thermostat later that evening, started the car everything was fine temperature was normal, car ran for approx. 10-15 minutes windows starting fogging up because of the humid weather so I turned ac on and within 10-15 seconds the car idled down and stalled. Then the car would not start back up. Turned ac off still not starting. It is getting fuel, no spark though. Please help

I have inspected the rotor and cap both look like they are in good shape, could it be the coil? I checked voltage at the connector that runs wires to the coil and it was showing 12.4 volts with the key turned on, not cranking. Not sure if this helps or if its relevant.
Thank you for your help!

I have not checked the compression as of now because I dont have a compression test tool, also I dont have a test light just a volt meter. Thank you again for your help I am desperate to get this fixed!

I have checked all fuses, unplugged and plugged back in all relays. I will check to see if camshaft is turning when being cranked as soon as I have an extra hand. Thank you again for your help Roy. Any other suggestions would be greatly appreciated. Phil

Thanks for everyones help! Turned out to be a bad coil. The coil showed 9.34 for resistance vs. The new one at 11.7. Thanks again
