I have a 98 Chevy S10 blazer that will not start. the engine rolls over when you hit the starter but will not fire. The fuel pump and fuel filter are brand new. The car was running great until it was parked on a Friday night and would not start Saturday morning. I have verified that there fuel up to the engine and I have spark down to the plugs. Any help would be appreciated thanks.

 

No codes? Can you borrow an OBD reader?

How did you confirm the presence of fuel? Did you check the fuel pressure?

How did you check the spark?
