2002 Grand Am won't start

I was getting ready for SMOG and had a code that said the MAF was bad. The car ran ok but would surge a lil bit at idle after awhile. I bit the bullet and bought a new MAF, installed it and now it won't start!! I put the old MAF back in and still won't start. The motor initially starts but then dies after about 1 second. It will do that a couple of times and then NO fire at all.

I have checked all wires in the area that I might have touched and there seems to be nothing amiss. Any ideas ????? I' F'n baffled

PS I went down and got gas just in case it ran out as I changed the MAF... I have had the stars align like that before.....

FOUND IT!!! I knew it had to be something simple or stupid that I had done. If I had found it right away it would have been simple. But I scratched my head and worked on it for a day and a 1/2,,,,,,, so now I will have to classify it as (another) stupid thing I have done.

When I put the new MAF sensor on I didn't see the plastic cover INSIDE the sensor when I installed it. Naturally when I went to crank it up the motor sucked the obstruction into the intake track. When I put the old MAF back on to try it the blockage was still there so the outcome was the same, intake blocked, no air, and one of the big three components ya need to make things go boom.

I took the airbox off and looked to see if the filter was in side ways, looked into the front of the MAF, nada , everything looked good. I pulled the MAF off and looked in both sides all was good. I looked into the intake pipe and it looked good too. Not until I stuck my hand in the pipe did I encounter the blockage. You couldn't see the clear plastic blocking the pipe. The first two pictures show what I saw when I looked in the pipe. I had to pierce the plastic with a secrew driver to get it out it was such a nice tight fit.

All's well that ends well they say, but I wish it hadn't been with egg on my face LOL

Yes it was , the same size as the air duct. It was the protective end cap that came on the new MAF. I didn't see it( very thin and very clear) and the minute I went to crank it, the piece got sucked off the end of the MAF and into the air duct about 1 1/2 inches down the pipe. It was so clear that I looked at it and never saw it, looked right thru it. It wasn't til I tried to put my fingers up the pipe to check for obstructions that I encountered it.

I haven't driven it yet to see if the code comes back. I was cold and late when I found it. hopefully this will be the end of my nightmare.
