I bought a 1968 Signet with a swapped in 318 this past fall that has not been road worthy since 2012. It went through 2 previous owners. The first owner put a ridiculous cam in the 318 without degreeing it correctly. The 2nd owner I bought the car from could not figure out the first owners mistake. He bought a new timing set lined it up dot to dot and did not degree the cam. Same problem. He removed the points ignition thinking that could be the issue and he switches to electronic ignition.
I pulled the timing cover and degreed the cam correctly and got the car running. The next problem to fix is the engine cranks with the key in the start position but there is no SPARK and it will not fire. Release the key to run position while the engine is spinning, and it starts if you catch the momentum exactly right. I suspect wires were crossed or something was perhaps wired incorrectly when the previous owner switched the car to electronic ignition. I have replaced all the electronic ignition components with good working parts and the starting problem still exists. I am not an electrical wiring genius. I have found while working on the car not to trust anything the two previous owners done to the car while they were trying to sort things out. It seems anything the two of them touched turned to shi_. Both should have had their toolboxes revoked.
I am not interested changing the entire ignition system to something else. I am do not what to reinvent the wheel. I am doing this on the on a budget. I am determined and committed to making it work with what I have.
Do you need to replace the original voltage regulator with an electronic regulator when switching from point to electronic ignition?
/\ Attached picture the way the ignition is currently wired /\
0. 4 pin ECU
1. Two (2) Gray wires from ECU to Distributor
2. Blue White wire from original harness to left side of resistor
3. Light Blue wire (that might go to the voltage regulator) from original harness to left side of resistor
4. White Blue from ECU to left side of resistor
5. Dark Blue original wire from right side of resistor to (I think) + on coil
6. Brown original wire to right side of resistor
7. Black Yellow ire from ECU to - on coil
8 Green Purple wire from ECU not used or connected.
