I don't know what's wrong

[Guest Tuna Rick]

  have a I have a 1990 Jeep Cherokee 4.0 I have to prime it with starting fluid every time I start it but after I prime it it runs fine all day only when I start it what could be wrong please help me

starting fluid?  for a fuel injection?  that is indeed weird.   how long do you let it crank before resorting to this?

Try jumper cables and see if it cranks faster and starts without a jump. My fuel pump relay go weak and wouldn’t latch while cranking due to a low battery (one cell was gone but the motor was so low compression that it spun over like it was going to start)
