Ok, I have been fighting some electrical gremlins.
74 2.0L FI 037 brain (now with 270 ohm ballast resistor) The car runs great for 10-15 minutes then dies. I tested the power relay and fuel pump relay and fuel pump itself and have power to all. After it cools off for 3-5 minutes it will start again. I have not checked for spark, but am guessing when it dies this is what is stopping. What could this be??? ECU / Brain / Computer? I know they rarely fail When I unplug my air intake sensor it has no affect on running. I thought maybe another sign of potentially a bad ecu / brain / computer. I have read it is supposed to richen the mixture. Here is a pic of my car just because I like threads with pictures.  |

I tested the Coil and it has power when the car dies. I hooked up a volt meter to the +. I was really hoping that would be the problem, as it is cheap and easy.
Someone suggested the CHTS. I thought these worked or didn't. They have a resistor built in, as I understand them. I replaced mine 15,000 miles ago. |
