Garrett76Zt Posted May 13, 2003 Share Posted May 13, 2003 Ok, I put the L28 turbo in my '76 280. the car has run for almost a year now so I know that fundamentally all my wiring is fine. Recently through the winter the car ran like crap. It was misfiring terribly and running really rich. It really seems that I was having spark problems. so today I swapped out plugs wires and put in a new MSD Blaster coil for some extra juice. Now I'm not getting any spark. I'm not sure if this is a potential wiring problem or what. I hooked up a multimeter to the + and - sides of the coil when cranking the ignition and didn't get anything. One additional question, the old coil sat in that bracket that was bolted to the body. Does that braket act as a ground in any way? Is that a resistor that is attached to the bracket? Does my new coil have to sit in the Old bracket? Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...
fl327 Posted May 15, 2003 Share Posted May 15, 2003 the oem bracket houses the ignition transistor that gets its ground from the bracket bolts. not having this might mean coil isnt getting the go ahead from teh ecu and vice versa. Quote Link to comment Share on other sites More sharing options...
Mudge Posted May 15, 2003 Share Posted May 15, 2003 I'm not sure how you would get no voltage though, ground should be grounded and + receives power from the key. The coil transistor though like Len said is what fires the coil. I hope I am remembering that all right, been awhile since I've looked at mine.
