GM-GMC: 93 GMC 1500 Fails to start, gmc 1500, electrical connections

Question
One morning I go out and my truck fails to catch. Lots of turning power but it doesnt fire up. I remove the air cleaner and check the injector plugs in the intake. Put them back on and it fires up and runs until I shut it off again. Same procedure before it will start again.
Might this be an electrical part of some sort?
Thanks,
George

Answer
My first suggestion would be to take a good look at the electrical connections etc around the injectors.  Also a quick resistance check of the injectors and compare them to each other.  With out having the specifications in front of me, they should defineately be within 10% of one another.
Hope this helps.
