12A Street Port with Weber 45DCOE Ignition Problem?
Car was running good. Parked for three weeks without starting car. Now it won't start. Checked for spark on trailing is okay. no spark on leading, switch leading ignitor into trailing slot, it got spark.... Switch known good ignitor into leading slot NO SPARK...!!!
I am running the msd box with a gutted ignitor on the leading but went back to original setup with a good ignitor to troubleshoot but still no spark on leading coils... Coils are MSD blaster brand new... what could be causing this problem. I relocated the alternator to the side but this should not be the problem. Any sugestions.... thanks |
maybe check to see if you have 12V at the terminal for the leading coil with the ignition ON.
|
check contacts and for broken wires in the harness itself.

I checked the voltage down to the ignitor contacts and have 12.x volts on both ignitors leading and trailing. But still only spark on the trailing plugs. any ideas... won't even try to start.... |
Do you have another dizzy to swap out? maybe the pickup in your dizzy is not working correctly. just a suggestion. hope you get it worked out.
|
also might want to check your cap and rotor for damages. check the coils; try swapping the L and T plug wires for the coils also.
|
check each plug wire for spark. if no sparky, check voltage on coil's + terminal.

So it looks like both coils will fire the trailing side... Just out of curiosity ( How many wires should be connected to the leading coil. I have a big black/white on the positive and a yellow/green thin wire to the negative... Am I missing something there? I am using the MSD Blaster coils for both leading and trailing. What's the voltage/ ohms shoud be.. I am getting 12.x on the - and on the + with ignition on.. the ohms won't stay put keep on changing... |
I have a feeling that your motor is flooded/no gas coz even with trailing alone, the motor should start. also, re-check your MSD 6A/AL wiring if you have no spark in leading.

I don't even get a trying to start at all... I will take the plugs out again, cycle the engine without the plugs by hand and let it sit for a bit... this used to work before, but I'm not getting any starting tries ..... |
try another distributor.
