Engine Mechanical problem
1990 Chevy Silverado V8 Four Wheel Drive Automatic 152000 miles
pulled tank and tested fuel pump by hooking sending unit straight to battery works fine. Will not work when it is plugged into regular wires. Traced wires did not see any breaks or bad spots. Replaced relay and fuel pump fuse. Also the ignition was replaced about 4 months ago. It died a couple of days ago and I checked to see if it was getting fuel but wasnt sprayed starting fluid in th throttle body and it would star but die of course. I also checked the pump before I pulled tank by runnig a wire from battery to the aldl g wire and nothing happened the book said pump was bad. Please help dont know what else to do!
