Pour a little into the throttle body - if it runs for a second, then that was the only gas getting into the engine. Check for 12V on the red wire that goes to all the injectors and check for an oscillating ground on the other wire (one group has Tan/R & the other has Tan/Or). If you can stick a pin thru one of the tan wires, ground it temporarily, & get the engine to sputter, then the ground signal isn't making it to them for whatever reason. My engine had sat in a junkyard for a few months and I had to hold the second wire grounded for a few seconds to get the injectors hot enough to melt the goo inside them. They've been running fine for the past ~200Kmi.
