Question about 2003 Chevrolet Suburban 1500

Suburban dies at highway speed

Almost the same thing happened to me this weekend. I was driving home from Oklahoma City to San Antonio in my '04 Suburban and just out of nowhere the engine died. I made it to the off ramp and access road and sat there a few minutes and then it started and ran fine for a few hours. Then near Round Rock it did it again. I got off the highway and sat probably 30 minutes trying to start it. It finally did start and ran perfectly the rest of the way. I'm thinking a fuel problem because when it finally did start it "almost" started a few times, then sputtered a little and then started. My "Check Engine" light has been on for several months so maybe something affected to CPU and thus would not allow it to start. Or maybe I had some kind of vpor lock or something. Outside air temp. was 104.

It sounds like a fuel pump getting weak and hot. First check the ground wire at the fuel pump pigtail. and replace the fuel fiter.

The engine falters at low speeds


The flashing engine check light means a code is being stored in the computer. You need to have this code read and this will tell you what system is malfunctioning.

2002 suburban 4x4 has very loose steering at high speeds


One thing I can think of is that the steering gearbox adjustment is too far from the pinion and needs to be tighter. But then your mechanic would have known this and reset it. Only other thing could be that you have the incorrect backset in your front wheels and that would make the vehicle squirly at speed. That happened to me when the wheels I stuck on my vehicle were outset too much. Other than that, only other thing is there is no toe in on the front end. Without a certain degree of toe-in, there's no drag at all and the tires will flop from left to right at will.

As I slow down or stop at a stop sign or red light it turns off. It drives good in a highway, as soon as I get out of the highway it turns off, or as I'm driving in the city. Took it to the mechanic can't...


Does it happen in stop and go traffic? If the answer is no and the only time it does happen is at speeds at about 40 mph's or better then its the brake switch its failing to cancell out Torque converter clutch solenoid (TCC). If it happens at all speeds take the vehicle to a shop that does SCOPE TESTING NOT A SCANNER this way they can hook the vehicle up to the SCOPEMETER and drive around with it to see what turns off (other than the vehicle) and causes the vehicle to die.

Vehicle dies


Sounds like a possible fuel pump problem...When they begin to go bad they will overheat and lock up, then work fine for a while and do the same thing again. By changing the filter you lowered the flow resistance and allowed the pump to work a bit easier but still being bad, it did the same thing again. There are other things that can do this as well, but pump is most common.

Highway driving problem. City driving ok.


If you have been to three shops,I'll assume that all the basics have been covered. Did anyone check computer stored codes? What did they see? If you are going to try to fix it yourself, you will need to get a manual and check each and every component, one by one. Also, outside of the realm of computer stuff, check converter to make sure its not partially plugged. At low rpm city driving it may be flowing just enough to get by on. Also check that fuel is clean and has no water in it.
