No start after switching to OEM ecu
No start after switching to OEM ecu *SOLVED*
UPDATED - See post #16
basically car starts up and struggles to stay at idle and dies after afew seconds. Good oil pressure, no codes on evoscan. Good compression across all cylinders. Plugs are saturated in fuel and raw gas smell from tail pipe. This all started after I installed oem ecu with a tephra rom.

UPDATE* getting only 16 ohms resistance with a multimeter test for the crank position sensor. Does this mean it’s bad? Also would this cause no spark no injector pulse?
Glad to hear that you got the immobilizer sorted.
I don't know what to tell you about the crank position sensor. Hopefully someone else can chime in.

did your ems require sensor upgrades? is Canada evo USDM? I recently got a file (modified version of my file) from an evoms user in germany and it wont start my car so I copied several modified tables to the original file, which works. our only diff is some MUT tables.

one important detail I left out now that you said timing belt jumped. my exhaust cam is set to retarded one tooth. But I didnt think that could cause no start..
