#987 of 1035 Chevy Suburban Fuel Issue?? by girlofsteel

Jun 06, 2010 (4:23 am)

Hi All, I have a 2001 Suburban 1500, just put a new tranny in it (oh happy day), drove it home from the shop it was fine. Next day, filled the tank, a short time after that the truck acted like it wasn't getting any gas, then drove fine for a while. Put 2 bottles of dry gas in it...ran perfectly. Chalked it up to bad gas. Put new fuel filter in it. Service engine light comes on with code 1810. Back to the garage I go. He puts the code reader on it, apparently the truck didn't know what gear it was in...but drove fine. Cleared the code. Next day get gas at a different location, same thing. Acts like it isn't getting gas, then drives fine, then does it again. Service engine light comes on again..same code 1810. Then it cleared itself the next day. The fuel pump has already been replaced (new) approx 3 years ago. Any thoughts? This truck has NEVER done this before I replaced the tranny. It always ran great. It has 138,000 on it. Could the tranny be affecting the fuel problem?? Email me directly at girlofsteel37yahoo.com thanks!!

#989 of 1035 90 suburban woes by beatdahouse

Jun 21, 2010 (11:49 am)

my 90 suburban is cutting out and dying, sometimes i can start it right up other times it wont start. i have recently just changed the entire wire harness behind the distributor as the wire were brittle and it was shorting my ecm fuse. i have changed coolant temp sensor, fuel filter, egr valve, cap, rotor any ideas? i am losing my mind.

You might want to try to figure out what the problem is when it's happening by carrying a spare spark plug with a ground wire. Can you hook one up? If you have a coil for each plug then you could have a 12v test light check for power at the primary connection on one of those. You could spray ether into the air intake and see if it fires on that. It's possible that you have bad fuel or a clogged intake in the tank. My own "burb" has an intermittent check valve that releases the pressure in the fuel lines. It doesn't happen often so I just bang on the tank bottom. That either re pressurizes the lines or jars the check valve but it starts anyhow. That usually happens when my tank is below half full. You could have debris clogging the tank screen. When you say cutting out and dying do you mean it stumbles before it shuts off? If so that could mean the spark is weak or the engine is starved for fuel. An immediate shut off might mean that a switch or bad connection turned the engine off. Can you think of anything in common with it's shut offs? Any driving condition, engine temperature, weather, fuel level, etc.? How long did you have to wait to get it restarted and did it start normally then?
 
Do you have any other car problems that are easier to fix? No, really sometimes odd things are related.

thanks, i regularly run under half a tank i have changed fuel filter but not screen in tank. also fuel pump relay like i said just prior to this i kept blowing ecm fuses had to change wire harness now fuses do not blow. but this new problem has occurred. i always get a big blast of pressure when i open gas cap could this somehow effect? yes it stumbles at one point i was on freeway and just put my foot in it and i made the 40 mile round trip but when i slowed down in town it started to stumble again. service engine light comes on when it stumbles and goes off when it goes again. it does not always die right away but now it wont start. one other question, when i turn engine to crank should i hear fuel pump running? i know after i turn off key it still runs for a few seconds. thank you for your help

I have a 1998 Suburban 5.7 gas . The fuel pump has been replaced 2 times in 2 years and gone out again . I did replace the relay but stll no pump noise when the ignition is turned on . Any ideas , both were name brand pumps , is there anything else that could be causing this repeated problem ?

#995 of 1035 Which year Suburban should I buy? by swanlass

Jul 05, 2010 (6:21 pm)

Hi,
 
I'm going to be buying a used Suburban in the near future. Looks like I can afford the '01 -'04 models. Are there any years to stay away from? Basically, what years had the least amount of problems? After searching this forum it seems like they have electrical problems,tranny issues and fuel pump issues...anything else?? I wish I could afford a newer one but this economy is killing me and the family is getting bigger. Thanks for your time.....
