Ok so I know enough about the j series and efi systems but I'm stumped on this problem.

ok so car cranked and ran good 3 days ago, no problems no check engine lights. Today I went to crank it and it will turn over all day but not fire off and run.
Now the only thing that is different from 3 days ago is the Nitrous system. I installed new solenoids, I releaved the fuel pressure buy removing the fuel pump fuse, 3 second crank and then disconnected the fuel line (as Honda does). Installed the new solenoids and checked all the line connections and then installed the fuse and it cranked right up. It ran for maybe 3 minutes then I shut it off and the next time I touched it was today.

Anyone have ANY input on this, or anything i can do in order to check the fuel pressure? Ive read in my Haynes manual that it could be the fuel psi regulator???? dont know why it would be though?
There is fuel in the line and I disconnected the negitive battery cable, removed the fuel cap ( tank pressure), removed the fuse and did a 3 second crank, checked the connections, installed the fuse and battery cable and still no crank.

Any ideas anyone????!!!!!!
