Spiders - P0107

[king_yukon]

I recently pulled the spiders out of my truck and put in the mpfi conversion. Not too hard to do by myself. From the time I opened the hood to the time I closed it was roughly 4 hours. It was pretty dirty under there so I gave everything a really good cleaning.

After all was said and done I took it for a spin, it seemed to be running great. I go out later start it up and get a P0107 - MAP sensor code. Never had this pop up at all before. Im certain I checked everything and Although it was a little dark Im sure everything was connected.

So I cleared the code and went on my way. Again the next morning start it up and same code. What the hell I think. Pop the hood again and start taking things off to get to the MAP sensor, and sure enough I forgot to plug it in. Let this a lesson, when you've worked 12hrs and decide to change your spiders, make sure you connect everything! HAHA

I read in another thread that some people hear like a air noise inside the truck near the bottom of the dash, I too can hear this noise but all is running good, no leaks. It just seems to be a common noise that comes along with the MPFI spider.

how much was the conversion?

Are you sure this noise is not something that did not get connected properly.

I did mine this afternoon. 2 hrs total and she runs like a dream now. Your old one looks new compared to what I pulled out, but then again I HAD to change mine it was so bad. Plus, I only had 1 piece of extra hardware when I was done, lol (one nut, but everything is bolted down so maybe I just did a more efficient job than Chevy did ). Got new Plugs as well, but didn't put them in.....maybe tomorrow.

$225 from Amazon for the Delphi inectors.

the nuts hold down accessories to the top of intake system so you might want to look around. Is the a black or grey nut or big or small?

 

[Dalton916]

1 big one. I checked everything and can't find where it goes....all SEEMS to be secured.....

 

[SunlitComet]

grey colored?

 

[Dalton916]

I would say yes without having it in my hand.

Psfr311 - total cost including new gaskets I bought and some other items was just over 300

Sunlit - I've read other post on here about the spider conversion. It's not air leaking just sounds almost like the fan is on when it's not. I've been told its the new conversion just sucking the gas.

there is a grey nut that hold the engine electronics ground terminals to the rearmost stud on thermostat housing. it is supposed to be a bolt with a nut molded in midway which makes the top half a stud then wire terminals and a nut on top of that.

get a pic of the nut if you can to get more details on where it goes.

Never heard of this you got links to this info. You did put the oval orings on the fuel body right?
