So I have a 85 pick up. She's been around. Replaced the fuel pump and injectors, tried a diff mass air flow still nothing. It turns over runs for a second then dies. Can keep it running by spraying gas into the intake. Just noticed yesterday the distributed wasn't bolted in . Wondering if the timing is all messed up? Anyway here's some pics...

 

If there are any cracks in the plenum pack (plastic air tube from the intake to air flow meter), it will not run. Had this issue on my old 88 runner. If there is a leak, it will not open the afm which turns on the fuel pump. Good luck
