Jeep Information


Hello all,

My Jeep was running normally until one night I tried to start her up and she just wouldn’t catch. I’ve since replaced all spark plugs, spark plug wires, fuel pump filter, and can shaft sensor. Fuel pressure at the rail is about 35 psi, and my battery is fully charged. I did a dry compression test on all 8 cyclinders.
1: 135psi
2:140psi
3:145psi
4:145psi
5:150psi
6:125psi
7:150psi
8:145psi
A friend and I got it started for enough time to take it a round the block. Was running fine in park and neutral, put it in drive and was idling around 200rpm and would stall out.

Not sure what else to do besides a leakdown test.
