Hard start and acts like the timing is retarded, then starts and runs fine. Sometimes the throttle needs a soft touch or it stalls. My guess is a sensor but I don't know where to hunt for one..

Update (07/20/2022)

replaced both water temp sending units on the head. Car starts and runs fine till it gets to operating temp, then it stalls and backfires. It is not running hot, water level is fine, lower and upper hoes are hot so it isn't a sticky thermostat. I'm stumped.

After finishing the car assembly and reconnecting the battery, the car cranks but does not start. The car was working perfectly, and I just replaced the spark plugs and cables. Any advice? I think the alarm system might somehow be blocking the car. I've tried locking and unlocking the car again, but the engine still won't start. Thanks for your advice
