I got a call tuesday from a friend of a friend who can't get his blazer started after running out of fuel. I figure sure I can handle that. I get there and find that it's a 1982 n/a 6.2 . First thing I did was ask how much fuel was in the tank and he said he put 5 gallons while trying to get it running. So I crack loose some lines at the injectors and tell him to turn it over a while. Didn't see any fuel. I pulled the stanadyne box filter off the firewall and it wal full of fuel. I blew through the hole without resistance. I disconnected a line at the fuel pump and it sprayed. Disconnected the filter to injection pump and got spray. I loosened the air bleed line and fuel squirted out so I used a little to prime the engine without success. Used my sentra to pull start the blazer at 20 mph in second gear for over a mile. I thought it was gonna light off a few times but it didn't. Tried starting fluid and only once did it almost fire. I cracked the fuel lines again and no fuel. The injection pump clicks inside when I tested it with battery voltage. I don't what else to do without removing the injection pump. Does anyone else have any ideas?
