I was setting my timing today and when I disconnected the est connector it caused my car not to start. When it is running and I disconnect it it dies. I was thinking it could have something to do with my msd ignition. Any suggestions?

 

Ouch

Yea I'd recheck your MSD wiring, I dont know if thats a "standard" feature of a msd box but it sure aint right

 

I dont know whats going on but i disconnected my msd and It ran great and I was able to time it. It seemed to idle better, could the msd be bad? What would cause this?

 

are you 100% absolutely possitive that the MSD is wired correctly?

Did they provide any alternative timing instructions?

 

followed instructions to the bone, all wiring correct, I believe if the wires were connected wrong it wouldnt' even start. I am looking at the instructions next.

 

Ive akways had to disconnect my msd to set my timing try that and let us know :-) lol and yeah im about 100% it will work :-)
been there done that
