Hey everyone. It's been a long time since I've come to visit the forum, but I'm so glad y'all are still here.
'94 350 2wd
Lately I rarely drive my truck. It sits in the garage, and driven less than 100 miles a year. It's about time for my inspection again. It may have been last years inspection since I drove it last, I'm not sure. Today I tried to fire it up, and it wouldn't start. It cranks, but no fire. I can hear the fuel pump priming when the key is turned. If I put starter fluid in the throttle body it'll go for a second or two though. There is no fuel coming from the injectors if you watch while cranking it. I was hoping for the easy fix and replaced the fuel filter first. While filter was off, I turned the key to 'run' just to see how the pump flowed, and everything seems fine. Fuel went everywhere. Reconnected the lines, and cycled the key a few times to get the fuel back to the TB. Then...still no start. I removed the the fuel line at the TB and cycled the key again, but never could get fuel up to the open line at the throttle body. I can hear fuel moving in the lines somewhere, but never spilled out.
At this point I'm thinking the pump is just weak, and doesn't have enough pressure to get the fuel up there. Before I remove the bed (full tank), and replace the pump and sending unit I wanted some extra input. Is there anything I'm missing here? I guess the only other option is going to Harbor Freight to get a gauge to actually test it, but I'd rather not.
Thanks for any help.
