Yestarday I undercoated my 91 Accord EX-R Auto, and put a new thermostat into it. The Thermostat housing broke, so that put me back until I fixed it(JB Weld!!!). After Filling the coolant back up, I go to start the car, and it cranks but no spark? I checked the wiring and none are broken, Reset the ECU, Replaced the ignitor with a know good one, cleaned the magnetic pickup and still nothing.

Any Ideas? Bad Coil? Bad Magnetic Pickup? Bad Dizzy? Bad ECU. Any had anything like this. Help, I need my car!!!!!

Bad main relay? Go through and check your fuses too. I used to have a 90 accord, and once and a while in the cold the relay would act up and wouldn't start. Could also be the sensors in the dizzy too. That happened to mine as well. If you have a service manual it gives you steps on how to check your coil, ignitor, and sensors that are in there to determine if they're good or not.

Ya I'm downloading the Helm Manual as I write this. Main Relay? That would cause no fuel, not no spark right?

Does the Accord have the grounds mounted on the thermostat housing also? Is the JB Weld somehow isolating these grounds from the block? Just a thought.

Ya, Someone else had this thought. I'm going to give adding an extra ground to this point just to be sure, That is if I can't come up with a new thermo housing today.

Well That exactly what it was. All that trouble for 1 wire, AND the Thermo housing still leaks. Getting a new one tomorrow.
