replaced fuel pressure regulator because it was bad. had gas in vacume lines. now acts like it is running out of gas then dies. will not restart for about a half an hour unless i use starting fluid and even then i have to do it five to ten times to get it to run. when it does start it does it under protest slowly chuging to a normal idle a smell of gas is pressent but none can be seen. it can do this as many times as six or seven times in ten miles i am using a lot of starting fluid and along with the gas that i seem to be running out of i am running out of patience.
