I have a 96 s10 blazer that starts hard. If I let the truck sit for 2 days
it will not start until I put gas in the carb. As soon as I put gas in the
carb it starts it runs like new. When I turn it off and try to restart the
truck it starts hard, but most of the time I can get it to start. However,
as I said if it sits more then a day I can't start it without putting gas
in the carb. When I first start the truck the fuel pump kicks on and is
pushing 45 psi, but it instantly goes down to zero psi as soon as the
electric primer kicks off. Any thoughts on what it can be? Fuel relay?
