Update i switched the firing order from 4-1-2-3 To 2-3-4-1... And the car started for a very quick second and then died right away. there is a extremely loud ticking noise under the dash while trying to crank over only while the eprom ecu is installed. would this be there correct firing order? I have a full 6 bolt swap inside a 1998 eclipse . let me know what you guys think. also i switched the wires to 3-2-1-4. Car started with very low rpm and died in about 2 seconds.
