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?

If its starting up with starting fluid, Im gonna guess injectors or fuel pump. Is the pressure your you are getting what is recomended for your vehicle? Low pressure is as bad as no pressure

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.

Not trying to Thread Jack,
but my friends '88 XJ has the same problem right now.

It also ran fine until it sat!


We too will watch this thread closely...

Yupp!

Not getting gas, no fuel pressure at the rail.

Doing the same thing as Always89's XJ!!!

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.
