I've finished throwing a new 7A-FE long block into the car. However it doesn't spark. I put a new distributor...still no spark. Wires test well, everything else is new. WTF am I missing? I've started going through the wire harness looking for damage, have yet to find any.
Is there a security type of thing that disables the spark? No Tachometer movement either. There is power to coil. Sorry to blast the forum, but I didn't find anything on the site. BTW this site was a great resource and addition to my lame Haynes manual. John |

No codes with a jumper wire, but the tool picked up Code 42, Vehicle Speed Sensor. No SPD signal for 5 seconds when the engine speed is above 3800 rpm. The book says the issue could be Vehicle speed sensor circuit, Vehicle Speed Sensor, ECM.
It also caught Code 43, Starter Signal. No STA signal to the ECM until the engine speed reaches 800 rpm with the vehicle not moving. The issue could be Starter signal circuit, Ignition Switch, Main Relay switch or ECM. Not all that helpful, I'll visually inspect the main relay and ECM tomorrow. |
