Hi. new here, been lurking, could use some help Please.
I have a 93 YJ with 4.0.. It runs well, slight miss, very slight. Died a few days ago, towed it home put in a new fuel filter. Ran fine for two days died again. No warning no sputter just slows to a stop. will restart and run for a few seconds then die again.. Cools off for a couple of hours runs fine for an hour or two, maybe a few days. does it again.
Any thoughts? the fuel pump comes on with the key and pressures up the fuel rail. not sure where to start looking. will change the crank sensor and O2 sensor just to eliminate them since they look like they need it but where to look next if that doesn't do it.
Thanks for listening. could use some input if this sounds familiar to you.
