Do you have power at the coil?
If not, do you have power at the relay board? If not, do you have power at the underseat logic circuit (under the passenger seat) If not, do you have power at the ignition switch? |

A 1.8L with L-Jet does not use ANY of the relays on the relay board. It uses the double relay below the battery to run the fuel pump.
Check for power at the positive side of the coil, and check the point gap. Then check to see if you have spark at the coil wire. You could have a burned rotor grounding the spark before it gets to the plugs. |
