Chevrolet Suburban and Tahoe No Start problems



  • Did you ever solve your problem? I have a 2001 Suburban as well that won't start on the first try. Usually starts on second or third. Runs fine after that. I read that it might be related to the MAP sensor. Have you tried replacing that part?
  • My 99 Tahoe is also having a starting problem. It will try to start but acts like it is not getting fuel. I was told that it was the security system locking me out. A mechanic said to turn the switch on and wait until the security light went out to try to start it. This worked for a while but now the light will not go out sometimes and the vehicle usually starts after 30 or 40 min. with the switch off. It is frustrating because it doesn't do it all the time. Did you find what was causing the problem with your Tahoe? The mechanic said a new module for the security system would be 8 or 900.
  • Michael, so far my 99 Tahoe has had her gas tank dropped, cleaned out, the fuel pump filter cleaned, and new gas put in the tank. One shop replaces all the spark plugs, due to rich fuel fouling. The next shop replaced her MASS sensor and a broken vacume line. I am told she works fine.
    I do not know as yet for I have a bill to get my Tahoe back. Although I hope this fix's the problem, I am unsure. My brother said if the problem continues to start my cleaning the MAP sensor then continue to replace the sensors until the problem is resolved.
    I wish every one luck in a well running vehicle. :D Myself included.
  • i have a 2003 Tahoe and it has done this 3 times. I heard that it has something to do with the fuel pickup in the bottom of the tank and that if you will tap on the bottom of the tank hard it will start. It did it to me yesterday and I hit the tank with my hand several times over the length of it and it started right up.
  • Especially in the winter when the cold starting take a ton of amperage... If you have this problem consistently, try new spark plugs. Sometimes 2 point plugs work really good in the winter... you might also find that the fuel mileage is better with the 2 points. Don't use them in the summer though... the engine heat will be very high due to the better burn. I have a 2001 with a 5.3 and it works for me. I still have a hard start sometimes in the winter. Good luck.
  • I have a 2004 Tahoe LT with the 5.3 V8. I have had a few times when the vehicle will not start either with the remote start or either original keys. The battery is fully charged, I've jumped the starter at the solenoid. The starter spins but does not engage.
    Recently I had a problem with the speedometer showing false readings. I received the recall for the cluster replacement. While I got the card a few months ago, I am out of the 70k mile warranty. However the little security light on the dash started to come at the same time. The factory alarm will arm as normal and will activate as designed, that little light never goes out while the car is in motion and the key in the ignition. Has anyone experienced this problem?
    When I turn the key there is nothing, while using the remote the lights come on as normal and the car attempts to start but during the time the starter would normally be engaged the is nothing. It will attempt 3 times then stop. Could this be an intrusion alarm locking out the starter and fuel pump, be cause it doesn't sound like it comes on either.
  • A few days ago I was driving home from work when i noticed the my tahoe was acting up. I was at a stop light and when the light turned green i stepped on the gas pedal and my tahoe kind of stuttered as if wasn't getting fuel. so then finally it started to go and i kept driving when i went to pass someone i stepped the on the pedal a little harder and it did the same thing. The next day the same the thing was happening, when i would step on the gas pedal not much seemed to happen. my tahoe wouldn't really go when i stepped on the gas pedal. so then when i was going to go home from work i tried to start my tahoe and nothing would happen, it sounded like it was going to start but it just wouldn't kick over. the tow truck driver put more gas into my tahoe and nothing would happen. so then i realized that when i turned the ignition over i could no longer hear the whizzing sound that is said to be from the fuel pump. So is it my fuel pump? i was told to replace the fuel relay and i did and nothing happens. PLEASE HELP!!! THANKYOU!!
  • I have the same problem every winter. When the temperature drops into the low 30s or lower my Tahoe will not start. I have to wait till the temp rises to about 50 and it will start just fine.

    When I try and start it, all lights come on as expected, makes all the same noises as usual, turns over just fine, but will not fire. Whenever I take it into the dealer it hasn't been cold enough to not start. They say there are no fault codes. One technition has heard of the problem and thinks it is the engine control module. But they cannot reproduce the problem to test it. The truck as a new battery (3-4 months old).

    I guess my question is has anyone else had the issue? I am headed to Tahoe next week and thats the last place I want to be with a truck that won't start in cold weather.

  • My wifes 2000 suburban is hard to start at times. It will turn over for a while and finally kick off and start. Sometimes it wont start too.

    I am not a mechanic at all so sorry about the descriptions I may give.

    She also notices the battery gauge "bouncing" back and forth alot. Can these two issues be related?

    Any suggestions?

    The service department at the Local dealer cannot find anything wrong.
  • I am havin the same problem, i just replaced my fuel pump thinking that would help but it didn;t, my mechanic said it was the aftermarket alarm system thats causing it to kill after I start it. after 10 or 15 min it will start right up. The alarm is resetting itself, So this morning I had someone take it to a car alarm shop to take it out. I;m hoping that will do the trick, I'll let you know. See if your vehicle has an aftermarket alarm and if thats not it it may be the passlock system. :)
  • I am having the same problem with my 2000 chevy suburban. I replaced my fuel pump thinkn that was it, but my mechanic said it is the aftermarket alarm system that was put in b4 i purchased it(used). I am having the alarm taken out this morning. The truck wouldn't turn over but would start after about 10or 15 min because the alarm would reset itself. If thats not it u will have to take it to the dealer to have the passlock system checked. hope this is helpful and everything goes well!!!!!!!!

    I've been having the same problem on and off. This week is at it's worst because my truck has not started at all. Maybe you shouldn't take it to Tahoe.

  • Hey thanks for the info. I've had my tahoe for 3 years and since i remember i've always heard that noise, is it possible that it took it this long to crap out? Do you think it is my fuel pump that is not working properly?
  • Thanks (msmocha). I have only the factory alarm system. I do have the Viper Remote start. Over the last week I have gone out and started the vehicle right off every time. When I start it i will do it several times in a row, and it has started. However on Saturday morning I went out to start it and it turned over very slowly like the battery was going dead. Then Sunday the same thing. Each time I started the vehicle I let it run for at least 10 minutes to replenish the battery. Monday morning the truck would barely crank but not enough to start. There is nothing plugged in so the only system running on the truck is the factory alarm system. I have noticed that some times when the truck is shut off and the key out of the ignition, there sounds like a module or something running in the dash. Hard to explain the sound. Anyone have any different thoughts? :(
  • Hope this might help and save time and $ for some people. If your Suburban randomly will not start, try checking the cables that attach to the battery terminals. They can become loose (in which case there is faulty contact w/ the battery and the car won't start or the lights flicker or go out, etc) frequently and for a variety of reasons. For example driving over speed bumps, on rough roads, etc. Corrosion can also build up and cause faulty contact as well. So, if your Suburban won't start and the battery is good, pop the hood and inspect the battery. Loosen the nuts holding the battery cables and if you see corrosion use a battery cleaner spray or wire brush to clean off the nuts and bolts/metal clamps that attach to the terminals. Then reattach terminals and tighten the nuts well. It's great if something as simple as this is the reason your truck won't start, instead of one of the many other potentially unknown and expensive problems. This works for me. ;)
  • In regards to my Tahoe and her intermittent starting problems. I am very happy to say that after many attempts of repair she is finally running!
    Replacing the fuel-fouled spark plugs was a start.
    Replacing the fuel pump and fuel filter helped.
    Cleaning her MAP sensor, MAS sensor, MAT sensor helped.
    The winning replacement part was her "Ignition Distributor" :)
    Replacing the distributor was the winning part to make her run even in below zero weather.
    I wish every one luck in their automotive repair' s.
  • I was wondering if you or your mechanic fixed your problem with your Tahoe not starting. My Tahoe, ive had since new, has left me stranded 5 times over a nine year period. Each time the next day, the mechanic says there is nothing wrong. I did add a after market remote starter, and felt that was the problem.
    The Tahoe is in the garage after a complete tune up, replacement of sensors under the dash, replace fuel pump, and it still won't run.

    Can you or your mechanic help me.

    I have an '04 Tahoe with about 85k on it. Recently it won't start on the first try and generally will on the second or third. This occurs if it has been sitting for a while such as overnight. If it is warm then it starts right up. The dealer said that it is the fuel pump. That on the first "cold" try it doesn't completely pump the fuel to where it is needed. They said I need to replace the pump and should replace the fuel filter at the same time. Does this sound legit? This is a big expense.
