^^^^^^



thats pretty much it,
i just finished installing every! and i pull the efi fuse go to crank, no crank bad terminal connestions at the batterie,

after about 5 minutes of cranking on and off for oil pressure, i never saw any, but knew it should have been there, may have not cranked fast enugh ?

any ways, i put the fuse back in and go to start her up, takes about 4-5 starts before she is running, just purrin,

i get out start checking for leaks, none,
great!

well then she died. a bit confussed, i start her back up and rev her a little bit i notice she seems a bit hesistent. kinda like when running with no afm.

i then realize my fuel pressure is just barely above 20psi, and if i remember correctly i had it set at 34psi at idle, 38 with vac off,

i am just glad i cought this before any damage could be done (aka test drive)
i also found that i have not bleed my clutch throughly enough, i did it when it was on the ramps, but i think i have a decent bubble in my slave cylinder,

well looks like i'll be pullng out the credit card and picking up a new walbro fuel pump..


just for what it' worth. when i bought my fuel pump it was when i first started modding, i lost the fp in my celica and needed a DD, pulled the supie's and figured a ebay walbro was the real deal. months latter i read sevral post's about their junk or atleast not up to par since

well looks like i'll be going through supra sport or drift motion for the new pump!

yeah i cranked it all the way up and when i did that the wire i had been using to jump the fp - B+ started to smoke and i knew some thing asn't right


i pretty much shut the return line off by turning it all the way in, and pulling the vac off it.

i couldn't imagine what would cause this to happen,
the only ting i can think of if the pump is good that there's a restriction in the feed line,

there brand new ss braided lines, so i doubt that, but im going to check for kinks and pinchs to be sure.
