Where is the fuel filter in a 1999 Chevy Suburban and could that be why the engine turns but does not start?

Answer 1

Crawl under your truck they are usually in line in front of your rear wheels. Chevrolet had quite a problem with some fuel pump electrical connectors during the mid to late 90s. These connections are located on top of the fuel tank and not easy to access. You can sometimes jar the connection by rapping the underside of the fuel tank with a rubber, I repeat, a rubber, not metallic, hammer. This will cause the connection to wiggle and sometimes make a better connection for the short term. Then, turn the ignition only to the "ON" position, but not "START" (so you won't have to listen above the engine noise), you should be able to hear the fuel pump come on for a few seconds. I bet your car will start then. My 1998 K2500 Suburban (454 engine) let me down a few times, but only while I was a long way from home, never locally. The connection had to have time to heat up and the connectors expand. The engine would then die. Sometimes restarting immediately and going another several hundred miles. Sometimes only going a few feet. I thought it was the fuel filter and kept changing that. After 140,000 miles, I decided to change the fuel pump because it had always been noisy. That required draining and dropping the 44 gallon gas tank. I discovered the electrical connection was discolored from overheating due to a loose connection. I took needle-nosed pliers and squeezed the male/female connections together. I also applied dielectrical grease to inhibit corrosion. That was 2 years ago. No more trouble since then. A few friends have had similar experiences with their Suburbans, Tahoes, and pickups. Same remedy worked for them too. Good luck!
