slownrusty Posted April 13, 2007 Share Posted April 13, 2007 Off the top of my head...fuel pump. Spray lots of starter fluid into the nipple on the intake manifold and see if it will start and run for 10-15secs. -or- crank it and see if fuel comes out of the gas line coming out of the fuel filter line...put the end of the line into a beer bottle as a viewing window.

MY77Z Posted April 13, 2007 Share Posted April 13, 2007 i would check the fuel injectors too, maybe they are plugged with dirt Quote Link to comment Share on other sites More sharing options...
Careless Posted April 13, 2007 Share Posted April 13, 2007 i took apart my fuel pump and found that one of the o-ring gaskets had clogged itself in the pump vane. I'm not sure how that happened, but as soon as i replaced them with off-the-shelf o-rings that were stretched to fit in there, the pump worked amazing, and now my car starts after 25 years of sitting under a tree... after being attacked by bondo and chicken wire (as one other z member noted ) Quote Link to comment Share on other sites More sharing options...
