Truck stop running. (Again)


Recommended Posts

So here I am again. I once had a good running 620 with an L18 Petronix ignion. The L18 blew up. So I had a rebuilt L20B installed. I got it running was running a little rough but running and idling. Then as if someone flip off a switch it just stopped running. Coil seems fine ignition seems fine. Only thing I can think of is I tried my 6month old Petronix. Which was fine before I swapped engines. I am not a electrical guy or an overall great mechanic. 

Any ideas I included pics of the wiring for the Petronix. 20220601_190248.thumb.jpg.313537bca707a8d5490454b466931f2c.jpg

Pull a plug wire, stick a plug in the end and lay on a grounded surface like the valve cover. Turn engine over with the starter. GOT SPARK??????
