Hey a couple of weeks ago I installed an aftermarket radio and rearview camera. A red light came on the dash but I didn’t pay it no mind. My car was fine until last week when it just wouldn’t start. Got a new battery, checked spark with inline spark tester, fuel pressure and engine compression is fine. Car starts for roughly 1-2 seconds after spraying some starting fluid inside air intake. Before I undo everything I did, has anyone seen something similar, Can anyone help?
