Had starting problems with my SUV. Towed to dealer, where I was told that the fuel pump went bad due to a clogged fuel filter. Called to complain to gm that the requirement to replace the fuel filter was not listed on their scheduled maintenance chart in the owner's manual, I was then told that the pump shorted out which caused the failure. This is an internal fuel pump mounted within the tank itself.

July 19th in denver colorado 2004 chevy suburban stalled on santa fe blvd. In heavy traffic. Waited 30 minutes and then started truck and went about 2 miles and stalled again called local dealership and had truck towed to dealership. Dealership replaced fuel pump under warranty. Drove truck 1.5 hours and same issue of truck stalling. Took back to dealership and mechanic on duty told me that it was a known defect with the 2004 chevy suburban and nothing could be done until the air temperature went down. Temperature was around 100 degrees. Problem is caused by high temperature and altitude. Problem is vapor lock. On the 22 of july dealership was told to replace the fuel pump again by local chevy area vehicle manager (avm). Dealership replaced the fuel pump again and I drove it for 1.5 hours and it stalled again in traffic. Took suburban back to dealership next morning. Dealership assured me that 700 new fuel pumps are available to fix problem and one would be installed on my truck on july 26th. On july 26th found out that fuel pump sent by chevorlet corporate would not fit the suburban and that I had to take my chances and drive it back to minnesota. Temperature was cooler and chevy felt it was worth the risk for me to drive it back to minnesota and let them know if I had a problem. Dealership also admitted that the fuel pump in the suburban was already the "new " height altitude version of the fuel pump and that the dealership had multiple vehicles with the same problem and chevy does not know what the problem is. Dealership says issue is with 2004 suburbans and silverados. Known issue at chevy and they are doing nothing to fix it. Suburban will still not work at high altitudes (denver) and temperatures in the 90s. Suburban was not fixed. Luckily weather cooled down. Call chevy 800‑222‑1020 refer to ticket 1-350803636 ask for arch summers he is the chevy representative I am waiting for call back from.
