Fuel, air, spark... Missing one or one isn't getting there when it needs to be.

My gut reaction is a dead fusible link somewhere, broken ground, dead tfi, or distributor spun around.

Can you pull trouble codes?
How will i know if the fusible link is dead ?

Well its home now....drove home on its own power. Definitely electrical related,The pump relay only worked for the injectors so i bypassed the EEC to the pump by jumping the pump test port with a wire and she started up.
When i got home though i disconnected the jump wire and to my surprise the relay now works for the pump. So now i have to find out why its intermittent. A short is likely but where to start looking is the question.

There are some schematics in the How to Tech section that most likely cover your vehicle...


Not so sure you're looking for a short as much as a poor connection that reconnected with the messing around you did. I would look at the engine controls schematics and retrace what you did to make it run... then go from there.

Check the connector where the pump relay plugs in.
