no start after engine change

[rat454vette]

i just changed the engine in my 03 corolla and now it wont start. im getting three codes p0100 p0101 and p0110 they all have to do with mass air flow sensor, i replaced sensor to no evail it starts and shuts right off. i checked all fuses and connections at computer, cant find anything wrong and i have also checked the grounds and they all seem to be hooked up. if someone can help id appreciate it thanks

Did you swap the ECU or not? What year is the donor engine?

[rat454vette]

donor engine is supposed to be out of an 03 as well, i did not swap ecm, i tested mass air flow and i got 2.4 ohms at about 75 degrees. i am going to check ecu in the morning. one other question is it possible something happened to ecu, car has set for 9 months with a dead battery???

The engine grounds (2) are at the back end side of the cyl head below the fuel rail line.
Are you 100% sure these are grounded to the head?

[TrdSpeed140]

the sensor wasn't installed backwards, was it?

[rat454vette]

the two two wire grounds on the back of the head are bolted up,ive hooked up my scanner(matco determinator) and took readings from the following coolant temp 39 degrees IAT 59degrees IAC duty cycle 36% mass air flow .4g/s i believe it is a ground because when i goto start the car i lose power to the scanner and i have to turn the key off and turn key back on to get scanner to re-communicate to computer

i finally got back to working on the corolla after wife blew motor in my suburban, and i finally found why the engine wouldn't run, the place i got the engine from somehow punched a hole in the intake manifold, i replaced intake and the car runs fine
