There is no pressure at that port, it is to attach a vacuum gauge.
try pumping the fuel primer on the top of the filter until it gets stiff. THen see if it will start.
I did that already it seams to get hard but when i leave it alone for a minuite it gets real easy to prime again ? also I connected my scanner and it does not communicate with it
Ok, the pressure does bleed off, but did you try to crank when it was stiff?
What is thge 8th digit of your VIN?
let me check Ill be right back
Ok, so that is the LLY. What scanner are you using?
