I am working on a 2000 jeep cherokee 4x4. It came in the shop with a 8 inch crack in the cylinder head with a blown head gasket, but was running, so I recommended engine replacement. The customer provided a re-manufactured engine. I replaced all parts from old engine.
I have removed timing cover and checked timing marks I have removed transmission and checked the flywheel. I have replaced crank sensor and coil pack. I have set the oil pump drive gear the exact way it came out of old engine also tried turning it several ways to see if it would start. Still backfiring thought the intake and exhaust and wont start?
Please help me!
