1990 chevy truck hard to start
hey I have a 1990 chevy truck with a 350 auto when it is cold or has been sitiing for a while you have to crank it for about 1 minute before it starts , what i have noticed is as soon as the oil pressure gauge rises it sends fuel to the throttle body and it starts and runs fine even when you shut it off and try to restart unless it sets for about a hour or so then it is the same thing all over again. I have changed the oil pressure sending unit and fuel filter no change, and it runs fine after it starts , thanks for the help Bill

Check your fuel pressure to see if it's holding when your key is off. If it's bleeding off, you probably have a bad regulator.
