I got a 1991 Chevy Corsica 3.1 Liter, Mileage 23,605.
the engine rotates but wont start, I Replaced the fuel pump, cleaned the injectors, an used Engine starter to make it fire, the fuel ant gettin into the pistons, all the fuses are good, any help would be apreciated
Use the schrader valve on the fuel rail to check for fuel pressure. If you have pressure than I would think it would be an ignition problem, Probably your coil pack. But also make sure you check your plugs and wires. It could be several things. So start with the most innexpensive first.
Also don't be afraid to goto the parts store and ask them to use their hand held computer.
Let me know what happens.
