i have an efi rs turbo engine in my car and had it running last week on the first try after the conversion, it hasnt yet got the turbo piped up i ran it without for now,

i went to start it yesterday after fitting an exhaust and now it wont start and i have no idea why, fuel is at the rail, sparks when i put a driver in the leads,

any ideas??

forgot to add if i leave it cranking for long enough it backfires

 

anyone got any ideas?

 

cam timing jumped?

 

timings not perfect yet, iv managed to get it started now

turned out to be the plugs, i took them out and heated them up and she started up,

i need to sort some decent plugs now i think
