changed lifters now car wont start.have fuel and spark.

If after significant repairs the engine suddenly doesn't start, you'll really have to recheck each step and each component operation to see what is happening. Engine's need fuel, air, spark, exhaust flow and proper emission controls, along with engine timing and compression to run. Anti-theft systems must be verified to be deactivating also, including that related to immobilizer keys. www.repairpal.com/repair-shops
