96 jeep what else can be check still won't start.if spray ether in throttle body starts then engine dies?

when was the last tune up? checked sensors? is it puttin out codes for check engine?

Well, if it tries to start on eether. You have a fuel delivery problem. Does the fuel pump come on for abt. 3 seconds, when key is turned to run position? Ck. for fuel press at the test port on the fuel rail. If not, ck to see if fuel pump relay clicks when you turn on key. If not swap it with another relay. HORN would work. What all have you done to it? Is the ck eng lite on? Obviously ASD circuit is working because coil is firing. But the asd also turns on the fuel pump relay. You may also make sure power is getting to injectors. Look at the wires to injectors, the wires that are same colors are the power wires. ASD powers these as well.
