help needed

i have a 97 rs 2.2 i changed the motor. now it will not fire at all.i am not sure its gitting fuel .when i put the new engine in i but the ground from the battery on the starter(i know duh lol)i wonder if that would have burned up the ecm. i checked the fuses and everything.

also there is a plug in down by the dist not the round one but the other one right by the dist i took it out of the the old motor it has oil on it .it looks like a tube. what kind of sensor is this anyone know.i think it maybe bad
