December 1, 2011I have a 99 Silverado with the 4.6 engine. It has 160000 miles and has run excellent since I have owned it. All I had to do was to turn the key to start it and it would start immediately. The last few days it has had to crank for a few seconds to start. I am thinking it is a fuel problem, but not sure. The fuel pump was changed at about 75,000 miles. Would a fuel pump starting to go bad cause this? Is it the fuel regulator. I changed the fuel filter a few months ago. I am looking for answers, any ideas?

December 1, 2011How is the condition of your battery? A short in the cells could produce a lack in cranking power.
December 2, 2011Battery is less than 1 year old. 800 cold cranking amps. The batteries in this truck have lasted about 5 years. This truck is a 99 and only the third battery. It cranks good, just takes longer to start now.

Without seeing it in person, it`s really hard to pin down. Just start doing basic troubleshooting and keep proving items"not the problem" and you will eventually find the "is the problem".
Best of luck, been there way too many times myself over the years.
