The spark plugs? I got a new set when engine was rebuilt i will clean them up and put back in and see if its kos of the carbon build up on them 

Just put my old spark plugs back in started strait away i think the ones that were in had alot of shit on them from the over fueling,running the xg ecu with out j3chip also but will get that programed to run with xg ecu.took it up road ran smooth as didnt miss or rev hang at all.cheers alot for all the pointers bloody awsome!!

Have checked module connector resistance and is reading 0.6v,then linked the tfi module pin 5 to pin 5 in connector and read 3.6 so will replace module it has spark but is very weak spark.have put original thermostat housing back on with connector for ecu coolant temp sensor and tapped another hole for aftermarket sensor,this has solved the flooding of engine when cranked,and have dropped the fuel pressure back to 30psi.have put xg ecu back in and will introduce the j3 once i get it running,it seems im slowly tracking the problems with your help cheers lads

Tested tfi module and pip signal (pip signal is pulsing between 3-4.5 volts when cranked ) does that sound about right? Iv noticed the injectors are pulsating real fast which could be causing the flooding,iv bridged the temp sensor as im running after market gauges. i read that the temp sensor can cause the injectors to pulsate fast and cause flooding if not connected.but still have no bloody spark

Got 12volt at coil ,12 volt to top of distributor, the leads were reading 2ohm have put the original ones back on that are reading 4-5ohm but still no spark,have takin j3 chip out of el ecu (which i intend to run) also tryed original xg ecu and no spark,my next guess is the hall sensor or tfi module???

Yeah il check all this out tomorrow,as when i crank it now its not even coffing or backfiring.yeh very tru you never know what someone has done to it prior.will give ya an update in next day or two cheers for ya help

The j3 was tuned for stage 3 cam,220cc injectors, disable smartlock and t5 gearbox.iv just had the dizzy apart with a mechanic and is fine.running about 40psi fuel pressure,i have also run an-6 braided fuel line with new fuel filter.it was running rich and was about to tune the fuel pressure but now have no spark but winds over 

Hey have just rebuilt a ef block 94dt head with stage 3 cam and valve springs ,220cc injectors (au),aftermarket fuel regulator, and el ecu with j3 chip.running original dizzy out of original xg motor.iv managed to get it started and idles fine but over 3000rpm wants to die,now when i wind it over it has no spark and is flooding any suggestions??

Cheers
