Here is a pic of the diagnostic screen from my m4.



I know i have a problem with coolant temp as the connect has just fell off the sensor.
Also does this mean i have a problem with the triggers or wiring from the distributor?

i have wired this ecu in my sefl to my celica gt4 st205 and swapped the engine and everything else. the car is turning over and im getting sparks at the ht leads but it just wont fire.

after testing the injectors they sound fine and the fuel pump is priming, there is fuel at my fuel rail but it just wont fire. Any help would be much apprecaited.

Was that screenshot taken when the engine was cranking? Sync status wont change to ok until engine is cranking or running and both ref & sync signals are present and correct so if that pic was taken when engine was at rest then it is normal.
Have you got your timing (crip) adjusted with a timing light?
Does RPM show correct in Motec during cranking (~200RPM)?

Have you wired the 3sg distributor like the MoTeC drawing?

Have you used the setup numbers in the drawing?

Have you checked the CRIP value to make sure your timing is correct?

Have you setup the injector current correctly?

What fuel trims are applied, is there any large negative numbers?

Have you watched any MoTeC videos to learn how to use & setup MoTeC ECU's?
