Does the engine light go on if you switch on the ignition?
When not, check power supplies and grounds for the ecu.

Are there any lights lit when you switch on ignition? Oil pressure, battery, etc.

you need star scan to do a diagnostic for this car, if the inmo light ON ?,

yes all lights on ...but not the inmo...just turn on 10 times ...and then turn off....but engine doesnt cranck...time ago other people try to cranck direct to starter engine relay...but crack without ignition signal and inyector pulse after that I connect elm 327 and appear not ecm signal...inmo active ....
I dont remember the code number ...after that connect DRBIII but only works in cars until 2005

If ECM is brand new you need to upload sw to it first , write VIN and SRI , also tire size and other settings, DRB III will not work , use WiTech with StarMobile.
If ECM is used you need to rewrite the VIN, SRI and relearn keys.

yeah I solved it ........can connection was cut .....but without DRBIII ...I have used elm327...to diagnostic.
thanks for the help
