I have a 2001 nissan altima that wont start. it has been siting for about a year not started due to motor being rebuilt. the motor is back in the car and hooked up now. the motor turns over but wont fire. its getting gas. its getting spark to distributor but not out to the plug wires. ive tried replacing the distributor but that didnt help. does anyone have an idea on how to get it started?
