Hi, I don know what else to do, a few days ago, my friend and I did the engine swap to my lexus es300, this is the history, few months ago, my son crash my wife's lexus, the car after that was ready for a dump place, but the transmition and engine remain perfetc, so I decide to find another es300 with bad engine, finally after some weeks I found it, so I bought this for $1200 and start the engine swap. We did every thing. remove the bad engine and install the engine from my crash car, the new es300 is 98 and the crash one 97, We connect all the sensor, connector and hoses, but the engine wont start, there is gas con the system, but looks like no spark, I dont know if I have to swap the computer or ECM too, please help me. the car is cranking but no start
