well it runs sort of . had it running was stupid rich I set tps and in the pms and it cleared it up I was trying to bleed coolant and it got warm so I shut it done and it fouled the plugs up a bit . sounds good but I gotta get it to idle and stuff I can't set the timing even yet .
 
So my next issue to sort before going for the tune it seems the PMS isn't seeing the vaccum for some reason I don't no why the map sensor is hooked up and fed vaccum by the manifold and it is t into the bypass valve on the blower

I disconnected it and sucked on the hose and blew into and still got no reading . any ideas @84Ttop . I am gonna have to check the sensor tomorrow
 
The map sensor is plug and play. I suppose you could have a bad sensor but I'm not 100% sure how you would test it. Are you seeing the reference voltage in the map pigtail?

Yeah i figured that , I have to check tomorrow and see im assuming maybe it just took a dump ill check voltage first and then maybe swap the sensor and see

@84Ttop here's what I am seeing on the pms for vac and it does fluctuate.1-.3 I couldn't put it into boost obviously .

First step is to figure out why i have no 02 sensor voltage reading. Maybe they are dead? And then maybe see why the hell i am showing .1psi as opposed to being in vaccum. i did order the sensor either way to see.

Also noticed iam not seeing maf voltage here. Gotta see what the deal is. I had an issue with a ground in the 02 harness pin backing out and maybe that may be an issue here as well.

Another thing i am thinking is that the vaccum needs to be seperate from the bypass valve i am gonna run the vac straight to the tree an t off my gauge and see if that changes the map sensor reading
