Ok first the car it's an 86 GT , 2.8 that needs work, PO replaced 4 speed with auto, came from Michigan
so lots of rust, car sat all winter ( weather like Michigan ). car needed to be moved ( land lord problem )
First the battery was dead, charged it . Still would not start, replaced it with battery out of my 87 .
It wanted to start but would only do so with starting fluid. Replaced fuel filter thinking that was the easiest part
in fuel system to replace. All systems go , car started and we moved it to my house . Now the problems
Charged and tested the battery took charge and tested good, put it in car and the dome lights would work, chimes
worked , turn key everything would go dead. Good news tracked problem to corroded battery terminal.
so then I had spark , car wanted to start but back to needing starting fluid. After starting a few time it no
longer needed it to start but would not keep running. Now for the kicker after a few attempts ( may be 5 )
and a few minutes of running each time the battery was low again.
So fuel problem not getting enough , and battery goes down quick
Not sure I can check fuel pressure, ( lack of know how and lack of tester ) so anything simple to try would
be great. thanks
