Did it, still doesnt start

87 Jeep Cherokee, 4.0, automatic

Sat for 2 years. Did the following already:
1. Drained fuel
2. Changed Fuel Filter
3. Changed plugs
4. Cleaned rotar and cap
5. Changed plugs

I have plenty of spark to the plugs
I have fuel at the pressure valve on the rail
It starts right up with Startign Fluid

Still will not start on its own, What are the chances that the injectors are ALL clogged? Any ideas?

Yeah, check the fuel pressure. Could be the rubber lines in the tank have deteriorated/cracked to where they're not delivering the fuel to the lines exiting the tank. It happens.

Its one of two things, bad fuel pump or loss of vacuum on the inlet side of the pump so it wont prime. Do a fuel pressure test to determine the condition of the pump. If it passes then look closely at all the lines.
