Welcome to Just Answer,
Your distributor needs to be reset in block correctly, sometimes a scan tool capable of reading timing data is needed to set the timing of the distributor.
Rotate the number 1 cylinder to Top Dead Center (TDC) of the compression stroke.
Notice: The ignition system distributor driven gear and rotor may be installed in multiple positions. In order to avoid mistakes, mark the distributor on the following components in order to ensure the same mounting position upon reassembly:
Notice: Installing the driven gear 180 degrees out of alignment, or locating the distributor rotor in the wrong holes, may cause a no-start condition. Premature engine wear and damage may result.
Ensure that the spark plug towers are perpendicular to the centerline of the engine.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
Tighten Tighten the distributor clamp bolt to 25 N·m (18 lb ft).
Tighten Tighten the screws to 2.4 N·m (21 lb in).
Important: If the Malfunction Indicator lamp is turned on after installing the distributor, and a DTC P1345 is found, the distributor has been installed incorrectly.
Before removing the distributor bring cyl #1 to TDC check the crankshaft pulley timing mark it must be in the middle of the "v" on the timing chain cover, remove distributor cap and check to see if rotor is pointing directly to the "8" on the dist base. if it is"off" just a little to either side loosen dist hold down bolt and rotate base to bring it inline with the '8", install cap back on and clear codes and restart. If the rotor is not pointing at the 8 and can't be rotated to the 8 the dist will need to be removed and set back in using the procedure in previous post.
