Six problems related to other fuel system pump have been reported for the 2002 Chevrolet Suburban. The most recently reported issues are listed below.
Whether it's idling or driving shuts off I replaced the fuel pump and the wiring harnesses that come with the fuel pump and still no avail it's caused a lot of time off of work and a lot of headache I work for a reputable dealership I worked on vehicles for over 40 years.
Some days my truck will not start some days it does for instance it will start for a couple of days consecutively and then it wont start for 2-3 days after a couple of days of just sitting. I have replaced the battery, the alternator , starter , fuel pump and I'm still experiencing the same problem. This happens all the time has been going on for the past couple years, lost my job because of non reliable transportation.
We went on a fishing trip from wilson, nc to new port news. I drove all the way there with no problem. We arrived at the james river bridge and my truck cut off. It crunk up and rolled a little then died again. It took me 25 minutes to park. I had to wait until it decided to stay on. We fished then we left the next morning. My truck drove good with no problem. It normally takes us 2 hrs. To get back home. My truck stared cutting off again when we got 40 miles from home. It took 4 1/2 hrs. To get home from 40 miles away. It was so hot. My family had to wait along a hot, long, lonely highway. It started cutting off more. I had the fuel pump changed and also the filter. It hasn't cut off today but the engine light has come back on. It's been 3 days since those parts was replaced. I don't know why my service engine light is back on. It was off before it started cutting off. Now it stays on and never goes off.
During normal operations under normal driving conditions the following occurred. Loss of engine at speeds of 60+ mph after driving one hour. Engine restarted with in two minutes. Problem occurred multiple times with shorter run times between each attempt. Over a three year time frame vehicle has required four fuel pumps all from different manufactures to eliminate the possibility of any compromised product batches. Total consumer cost. $3000.
My 2002 chevy Suburban has intermittent but increasingly more frequent and longer duration starting problems. My research tells me that it is exhibiting the exact same symptoms as the 2000 and 2001 Suburban models that were under a 2005 fuel pump harness recall. After nearly 4 months of dealing with this problem, researching it, and trying to convince both my local mechanic and the dealership to replace the pump, my Suburban finally failed to start at all today. Tomorrow my local mechanic is going to replace the fuel pump and relay. I am angry to discover that the 2001 and 2000 models were under recall for this very same issue, but the 2002 models were not included in the recall and the dealership -- courtesy Chevrolet in san diego -- despite 3 recent visits there with this problem, failed to mention this recall of those earlier year models. They failed to even recognize that this could be a problem with my Suburban. They won't do anything unless a computer diagnosed code tells them what to do. My symptoms are the same and I'm realizing now how fortunate I am that this car did not die on me in the middle of one of the many interstate highways in san diego county. I'm also fortunate that my car did not catch on fire! I'm asking you to look into how many 2002 Suburbans have the same fuel pump and fuel pump harness issues as the 2000 and 2001 models. The date listed below is the first day the car acted up. It has been ongoing progressively since then.
Driving at highway speeds, car engine died immediately after sputtering and losing power. First time this happened, I pulled off the road and restarted the car almost immediately. Drove another 600 miles without incident. Second time, car died again at highway speeds. Restarted after 15 minutes. After reporting the problem to on-star and having remote diagnostics run, I drove another 25 miles towards dealership rather than waiting for tow. (118 deg heat in desert sun). Engine failed again about 200 yds from dealership. Dealer replaced fuel pump, pressure regulator, and filter. Cropper auto group in casa grande, az, kept the defective parts. I have had problems before with fuel level sensor indicating properly on this vehicle. This repair also replaced fuel level sending unit. $800+ repair. 60,000 miles on the car. Extremely hazardous loss of power and control when engine dies without warning at highway speeds. Noticed at least 5 identical complaints on NHTSA website: oid id numbers 10041486, 10079660, 10099685, 10100051, 10126511.
