You have the rest of us stumped now.
Glow plugs do not spark, so where are you not getting a spark. diesel(heavy oil) use glow plugs, Petrol(gas) use spark plugs. Diesel, only use glow plugs for cold start, after start they usually turn off. Diesel engine on my boat does not have the glow plugs connected, Still starts and runs fine. So what is the problem
