I have an EG with LS swap. It ran and started before, but now it doesnt. It cranks but doesnt turn or stay on. I changed the battery, the alternator works, starter works, there's gas, the fuel pump comes on, I replaced the dizzy along with the coil, cap and rotor. Still wont start. But when I spray that starter spray thingy into the intake/manifold, it cranks better and almost starts, but still wont run. What do you guys think?
