Hello, I have a 1992 Toyota Camry. We had to replace the engine on it. While in the process of replacing the engine, we forgot to tighten the grounds all the way and we believe we messed up something. We have replaced the distributor. We are getting fire to the distributor; however, no spark. We were testing the igniter with a test light and we received the spark. We have already replaced the ECM once; however, not sure if they sent us a working ECM. We need help. We have been working on this car for over 3 weeks trying to get a spark. We have check all the fuses, the relays, and the wiring. Any suggestions would be greatly appreciated. My son will really be thankful since this is his car.

Before you do anything get a code scanner. You can borrow one from Autozone with only a deposit.

Does this car use an RFID car key? Keys may not be programmed.

I am not sure what you mean by a RFID car key. The key we use to start the car is just a normal metal key. No chip in it. - by the way we get a crank but no spark.

RFID is the term used generic term used to describe the chips with a chip in it.

I'd look for any ECM codes first.

If the car has a crankshaft position sensor, I'd look there too.

If you have a distributer, then check for spark at the center conductor.

If your getting it there, then suspect either the rotor or the cap. The cap can have carbon deposits in it.

Check all the plug wire resistances.

You checking for spark by taking a plug out and connecting it to a good ground or using an actual spark tester?

We don't have a crankshaft position sensor.
Brand new distributor... We are not getting a spark at the center conductor.
We pulled out a plug and connected it to a good ground.

Did you check for codes?

How about the temperature sensor? This controls open or closed loop mode usually.

The ignitor generally needs 12V and probably a pulse to ground. I hope you have some details. Check with a voltmeter from the input of the ignitor to ground and from +12 to ground. You should see a signal change when cranking. This should eliminate the ignitor as the problem.
