Did I put fuel filter on backwards




They have an arrow pointing which way it is to be installed - did you see that? They have a check valve in them so if it installed backwards, no fuel. When you turn the key on don't crank it right away, let the fuel pump prime, then turn the key to ON and hold it while it cranks. If it doesn't start after several seconds, turn the key to off and wait a minute, let the starter cool down. Then repeat. After 6 tries you will have to look into how you installed the filter.
