I have a 2001 suburban with the 326. Just in the past few weeks I have been seeing that it takes two and sometimes three attempt before it will start up. Once it does start it runs great. No hesitation and great power. It just takes a little to get her started. I spoke with the shop mechanic where I work and he suggested new fuel filter, and plugs. This weekend I changed the fuel, air and oil filter. I also replaced the pcv valve and all of the plugs. The old plugs had some carbon build up but not alot. The fuel gauge was on empty so I put in some new fuel and some Lucas injector cleaner. It fired right up. I thought I had her beat. I drove down the freeway for 20 miles. I pulled into a lot and let her sit for 30 min. I tried to start it up and it did the same thing. Any help out there? It spins over just fine. No lag in the starter and the batteries check out just fine.

Hello all I have a '99 burb (5.7L with 71K miles) and replaced the in-tank fuel pump and filter about 5 months and a 1,000 miles ago as I was told a noisie fuel pump is a sign of a bad bearing, plugged filter, or both . New fuel pump makes more noise now than the one I replaced at 70K. Are these fuel pumps normally loud ?? Truck runs fine, but other burbs don'y make the noise mine does. Any clues?? Thanks in advance JMDB92 |

I have a 99 Suburban (200,000 mi) and lately when I fill the tank you can smell gas fumes inside the truck until the gas gauges get to about 3/4 full then no fumes. My mechanaic did the smoke test on all of the lines including the charcoll filter and did not discover any leaks. We are stumped. I really love my Burb Thanks
