Need Help please read.

1988 Cherokee 4.0 inline 6 automatic 4x4. Didn't run when I bought it had been sitting in a barn for a yr and a half. Also wasn't getting fuel when i bought it. Has 250K miles on it. Motor was rebuilt at 200K miles.
All Fuses are okay.

It is getting fuel but no spark. What has been replaced in the past three days:

Battery (replaced cuz there wasn't one)
Battery Cables (Destroyed)
Spark Plugs (Way past Shot)
Spark Plug wires (weren't any on the jeep)
Ignition Coil (Bad)
Relay/ Ballast Resonator (Bad)
Crankshaft Position Sensor (Just Because it is known to cause problems)

Being replaced tomorrow if bad:

Rotor

I am out of ideas.

Please Help.

Thanks,
Evan.

Double check ground on block and make sure you are getting spark at the coil. Swap the relays around under the engine compartment also. Start there and return here with results.

Dumb question: do you mean spark from the distributor to the coil or vise versus?

He prolly means spark from the coil to the distributor. The grounds thing can be a cause for no spark as well. The negative batt connection to the block and the ground from firewall to block.

I cleaned the negative connection at the block as well as the ground from the firewall to the block.


I am not getting spark to the cap.

Brand new.


Update. That relay that I replaced, well when the old one was on the fuel pump wouldn't run But I did get spark. Now with the new relay installed The fuel pump runs but no spark. I put the old relay back on and sprayed starter fluid in the intake and it started right up. I am thinking maybe I got a bad relay.


Edit: I got it to start with the new relay but only after I used starter fluid in the intake. And it doesn't work every time. It is like the spark is intermentted.

Update since the relay. Fuel Pressure Regulator started leaking a few nights ago so i replaced it. The fuel pressure seems to have gotten a bit better after changing that out. But still not running. So... I took out the injectors and let them soak in a bucket of B-12 for 24hrs. I let them dry for about 12hrs. I just got done putting them back in and hooking everything back up. Cleaning the injectors did seem to help a bit. It is actually trying to start now, but wont.

Any ideas?
