help with a swap :)

ok guys and gals my buddy is doing a swap and i am trying to help him. i normally don't do da's but i told him i would give him a hand. so we got everything wired and the motor turns over BUT it dies. now there is a big ass sensor in the picture it has 2 prongs almost right above the oil pressure sensor

we didn't take a pic of it but this is the best pic i can find. what is that sensor and will that cause the motor not to stay on?

that sensor is the oil temperature sensor which goes to the cooling fan relay on the DA - won't keep it from starting, or running and it is not used for EF/ED swaps

it ending up being timing. for some reason its not holding the timing no matter how many times we redo the timing, so he is going to get a new belt kit
