I have an 84 300D and I have tired everything in the world.... Car has plenty of fuel and will crank and crank and crank but it just wont start up... the motor cranks more than fast enough to start and white smoke putters from the back but the car just wont turn over. I popped the line off the injecters today and checked and they had fuel, I pumped the primer and the fuel didn't move or anything... Is it stopped up somewhere?
