    It wont crank, I just had the fuel pump replaced almost a year ago.

  • mketchens Mar 01, 2009

    smacked the hell out of the gas tank, still no start.

    Good ground, good connections, still no start.

  • mketchens Mar 01, 2009

    Yes checked all fuses, including under the hood. Lights, radio, instrument panel and gauges work. I looked up the code and yes you are correct with that list but none of them seem to relate to my problem, however just for giggles i removed the gas cap and checked for holes and cracks. I cant drive it right now so I am unable to check for it to comeback in a day or two ...LOL....

    When I attempt to start the vehicle all the guages come to life and the lights come on and everything, what I hear is it attempting to crank like one time I can see the belt rotate maybe an inch and half to two inches (also while trying to jump it). It sounds like the battery is dead but its not! all guages lights and rdio will work.

    I took the altenator and had it bech tested, it Failed... got a new one, installed it and same thing will not start....I charged the battery as well still no start.

    The wire to the starter is good.

    One ground strap from the engine to frame is corroded about halfway through should I use the jumper cables to bypass that and see if it works?

  • mketchens Mar 06, 2009

    while the neg terminal is attached to battery?

  • mketchens Mar 06, 2009

    still nothing

  • mketchens Mar 06, 2009

    Yes, I can rotate the crankshaft.

    Starter tested fine.

Is the engine cranking but not starting? if so check the fuel pump. Sometimes a good smack on the fuel tank can get it going again but if it works it's a temporary fix.
Hope this helps!

    quitting while driving then not cranking sounds to me like a bad ground engine or body...........check the connections from the battery to the engine and body.....consider using a set of booster cables to create a new temporary ground cirut.

  • s60six Mar 01, 2009

    I found some info on your code and it doesn't appear that it would cause the problem.But i'm not sure if were looking in the right place to resolve the problem. When you turn the key what happens? (do the dash warning lights work? what do you hear?)
    Do you get power to anything? (headlights radio interior lights ect....)
    Another possibility could be a blown fuse have you checked the fuses in the electrical center under the hood as well as the ones in the dash?

    Here is the info on your code that i found.

    A code P0440 could mean one or more of the following has happened:

    • The gas cap is not installed or working properly

    • The purge solenoid has failed

    • The canister is plugged and not working properly

    Possible Solutions
    With a P0440 OBD-II trouble code
    , diagnosis can be tricky at times. Here
    are some things to try:

    • Remove and reinstall the gas cap, clear the code, and drive for a day and
      see if the codes come back.

    • Inspect the EVAP system for cuts/holes in tubes/hoses

    • Inspect for damaged or disconnected hoses around the Evap purge solenoid

    • Check and/or replace the sensor

    • Check and/or replace the purge valve

    • Have a professional use a smoke machine to detect leaks

  • s60six Mar 02, 2009

    ok, Inspect the main wire that goes to the starter. It may be broken off most of the way and not giving the starter enough power to start it. However that doesn't explain why it quit while you were driving. unless it shorted out on the body of the starter..........A big short will stall your truck! if the wiring is good your starter may be shot.
    the other possibility that comes to mind is the engine itself may have an internal issue causing the problem (something broken and binding in the inside of the engine)but if that was the case you would have noticed a loss of power and probably some severe noise.
    Keep me posted! thx

  • s60six Mar 06, 2009

    ye try running them from the neg side of the battery to the engine (something metal)

  • s60six Mar 06, 2009

    there are still a couple of things to try first get the starter tested if it checks ok then you may have an engine problem like i described earlier...........Try to turn the engine manually with a socket on the end of the crankshaft (you may want to remove the sparkplugs to make manual cranking easier) see if you can rotate it several revolutions without much effort or any binding.
    let me know how you make out.

  • s60six Mar 07, 2009

    have you tried to jump power directly to the starter to see if it will turn the engine?
    using a set of booster cables run the neg from the battery to the body of the starter
    run the pos from the battery to the large terminal on the starter then cross out the main batt post to the small solenoid post (starter trigger terminal)
    If this works you should be able to get it started if you do this with the key in the run position.
    also if this works then you have an issue with the starter trigger circuit
    let me know how it goes.

Sounds like the computer is putting the car in limp home mode you need to have a scanner hooked up to the computer and see if a code is set and then go from there to repair the problem.

I have a 99 Ford escort zx2 and it only does it occasionally, but if I'm going on a highway at 65 MPH, it wants to slow down and only go around 50 MPH. Sometimes the wheel locks up and service engine...

Sounds like a week fuel pump have the pressure checked at a local repair shop. Also if it has a lot of miles on it the catalytic converter could be stopped up also have the local shop check it out it is real easy to check.

Randon stall, no start

If it is the 2.5 v6 , you most likely need the distributor replaced. If it is the 2.4l cam and crank sensors would be most likely cause.

Stalled twice while towing at 65 mph. sputtered

If the scan will narrow down which o2 sensor it is and replace it. If it has more than one on that year that is. Under load you will probable have a richer fuel mix. If the sensor is going going bad it may only get out of spec reading under heavy load and warmer temps. I have had similar issues with GM and it was easily fixed.

2001 Chevy Tahoe - Stalls and restarts while driving

the only thing i could think of is a fuel shut off switch malfunction

1 Answer

Car shuts off while driving. usually while its still moving, I can put it in neutral and restart. In the beginning, it only happened when I hit a bump in the road. Now it just happens.

I had a similar problem. When I was driving on highway with 70 mph, the car suddenly stalled everything went off. I managed to get off the road then I tried to start the car, it did not start. After 5 minutes I tried again and it started running but after several hours it stopped while driving again. Took it to the dealer, had the ignition switch changed and it solved the problem. Costed $300. ( There is also a recall on all 99 Acuras for the switch. Mine had been replaced so they did not treat it as a recall. If yours was never replaced you can have it replaced for free)

Has the fuel filter been chg. lately. If it has, maybe a fuel pressure test is in order. Fuel pump might be geeting weak and does not show up until it gets warmed up. Fuel pumps are a common problem on this type of cars.

1995 tahoe desiel stalls when driving

I used to live on a farm where we had a number of Chevy diesel's in the 90-98 year range. The 6.2 and 6.5L diesel's in those trucks were known to have problems. A very common problem was with the fuel injection pump going bad, causing the engine to intermittently stall for apparently no reason during driving.
