OK, I have read through a ton of posts and am at a loss. I have an 88 XJ with the 4.0 and I was driving home from work and it did this little stutter, like it ran out of fuel, then it just dyed. I got towed home by a friend then started looking around here to see what it might be. This is what I have done so far, in no particular order.
1: Checked for spark, it has spark. I replaced the cap and rotor just for the heck of it.
2: Checked the Crank Positioning Sensor, it reads 199 Ohms at the plug on the firewall. As I understand it that is within specs.
3: When I crank the engine, I can smell fuel and I get good pressure from the little valve on the fuel rail. And I can hear the fuel pump kick on. I am going to replace the fuel filter just to make sure.
4: I sprayed starting fluid into the intake just to see if it would attempt to fire but it did not help at all. I would think that would have got it going for at least a second?
5: I checked the compression, and one of the the cylinders only reads 60 lbs. Is that my issue? All the others read 115-125. I would think it would at least run, just not very well.
Let me know what you guys think.
Thanks in advance.
