My pickup start to have a fuel pressure leak abruptly over a weekend. Currently my pickup is very hard to start but once the engine is running it runs smoothly and I have not notice a drop in fuel economy. I can hear the fuel pump running and it is relativily new. What could be casuing this problem? Is it worth changing out the fuel regulator?
