My car has spark and ehen i took off the gas line there was pressurein it

Do you have the proper tooling to test the fuel system for fuel pressure? Disconnecting a fuel line can cause a fire hazard and should be left to professionals or something with good know how at the very least. Testing overall needs to be performed to see if you have spark, adequate fuel delivery, and proper air intake to the engine, as well as necessary engine compression and proper timing. This will require some hands on effort for each area to drill down to the source of the concern.
