87 TA fuel pump not working

I have had my Ta sitting for awhile now.I would say about 6 to 8 months.

Re: 87 TA fuel pump not working

if the pump doesn't run during crank, it's probably shot. even if the relay tanks, tho ops will run the fp once oil pressure exceeds 4psi.

gas easily turns to crap in that time w/o stabilizer and can gum up a pump. i've had it happen before to a new pump. luck of the draw sometimes.

does the relay 'tick' for key on engine off (koeo) ? should tick ko (fp prime) and tick again 2sec later (fp off waiting for start).
