so the pass few days ive been having trouble starting my engine. sometimes it starts and sometimes it doesnt. ill start it up in the morning and it will run for a about a minute then just dies and ill try starting it again but no combustion... i notice if i wait awhile ill be able to start it again but sometimes it will stay running and at times it will die again. i changes my plugs and i still have the same problem. i have a msd iginition set up external coil msd cap ngk wires ngk bk7re plugs rc injectors blox fuel regulator but im not sure if its fuel or ignition causing my problem. also at time when i try to start it makes a wierd boggin noise. any input would help thanks
