3.1 Help!!!

[82 meeno]

I have this posted in alot of places trying to get some help quickly, so don't be surprised if u see it more than once....

I got my 3.1 installed, bolted down, wired up....

I turned the key to fire her and she just turned and turned and would not crank.

I definitely have fuel, and spark.

Could this be my crank sensor? I pulled mine off of the old motor before i took it to the junkyard, but, i didn't think to replace it until tonight.

I do rmember when i heard it run at the junkyard, it was having problems turning over initially but ran fine....

What is the difference between the crank sensor behind the block and the one on the harmonic balancer?

Also, the plug that goes into the bottom of the oil is not the same as the plug that i have leftover.... The color of the plug wire on the pan is purple/yellow; the one i have left over is looks like a brown/gray(could be wrong, its pretty faded and oily).

What does this oil pan plug do anyway?

I hope i wasn't too lengthly.

Turn your attention away from the oil pan. This may take awhile to figure out. Be patient.

If it were me I would wonder about ECM, sensors, etc.......

Thanks, I appreciate that.

I took some time this evening and we back through all the wires, sensors, making sure everything was plugged in properly. i switched out the ecm with the old one that i had tested ... i still got spark and both ends but no fuel to the motor...

i sprayed some carb cleaner down the throttle, started it and it backfired ,,, waited about 10 minutes and she ran for about 10 seconds and shut down...

Now i need help narrowing down the fuel problem. is the Mass Airflow sensor....
