Question about 1998 GMC Suburban

2 Answers

1999 F250 7.3 Diesel will not start

I have had both batteries checked and they both are reading 12.45 volts, the starter was benched checked at Autozone and the bendex comes out and spins and I've had a relay on the fender well checked and it too was good. When I try to start the truck all I hear is a clicking noise. That's it! No trying to turn over or anything. Could it be the starter or a bad ignition switch? Please help!

    how do i find the reserve amperage and what's a drop tester?

  • beetlebob Sep 10, 2009

    The amperage in both batteries were around 560 CCA. So, I replaced both batteries and it is still doing the same thing. I'm just getting a clicking noise. That's it. Any idea on what might be my problem?

  • beetlebob Sep 11, 2009

    Well I've replaced both batteries with brand new ones, the battery terminals are good as well and as far as I can see, the cable on the engine is good. I will look at the relay today. I think my book showed one for the starter. For the faulty solenoid, are you talking about the one on the starter? Fender well? or the Glow Plug Solenoid? The one on the Fender Well checked good, I just replaced the Glow Plug Solenoid because it broke on me putting it back in. If they bench check the starter and the bendix pops out and spins, wouldnt that solenoid on the starter be good?

  • beetlebob Sep 11, 2009

    I took a jumper wire earlier today and tried to start the truck from the starter relay on the fender well with the key on. I got the same clicking noise and it sounds like that clicking noise might be coming from my starter. Is there a way I can do the same to my starter and see if it is the problem? I know it checked good at the part store, but does that really check the solenoid on the starter when you take it in to get checked on the bench?

  • beetlebob Sep 11, 2009

    It was the starter. It was bad which is weird because I had it checked a few days back and it was fine, but when I took it in today and they put a torque against it, it didn't do anything. I replaced the battery and she's running just like she use to. Thank you for the help.

    a drop tester is a thing for testing batteries ,it has a big resistor ,a spike and a very heavy cable .when put across the battery it glows red hot and reads the amperage being drawn ,if battery isnt holding a charge then this will show it up .Just because your volt meter shows 12v doesnt mean to say that batterys are any good whem you have a cell down .Had this before with a guy with a winibago ,i fitted two ne batterys and it was fine but got slated off to his mates that i was a cowboy because his voltmeter showed 12v ,and to start he kicked in the aux batteries .Stupid bar room mechanics

    still clicking?? so iam going to get talked about again but who cares .Right still clicking on starter motor ---causes

    1 battery

    2 earth cable from engine to battery

    3 dirty corroded battery terminals

    4 faulty solonoid

    5 dirty contacts on back of ignition switch

    6 faulty relay contacts

    plus most likely something else that i havent thought of ,still nobodys perfect ,but i would try puting a jumper lead from the starter motor fixing bolt back to battery ,a proper jumper lead and not one of these cheapo chinese boost cable type.try it and get back to me if it still plays up

  • Colin Stickland
    Colin Stickland Sep 11, 2009

    try the earth cable on the starter direct ,although cable looks good it could have a high resistance on one of the connections.also run a cable from the battery direct to the small connection on starter solonoid and see it that makes it start ,if with the extra earth lead on and a direct feed to the starter motor solonoid it should go if the motor is ok ,What about positive feed to big terminal ,try flashing it with an old jumper lead to make sure that you have a nice juicy flash .if all that fails change the starter ,or your engine is siezed solid ????best of british with it anyway ---from spain ,

    never mind the bumper whatsit ,try what i said that way you will know if the starter is producing enough torque to turn engine over ,and to locate the fault

Did you try taking the gear hand out of park and into drive and then pushing it hard into park and then trying to start it? Also change the agnition switch!

Hello I'm having problems with a starter. It is on a tractor with a 24 volt system. It acts like my batteries are dead but I'm reading 24v and good amps. Will a bad starter act like bad batteries?

but there are some checks to do first
using a multimeter check the voltage at the main terminal of the starter solenoid
check the voltage at the small terminal and check it then with the key in the start position
if you have a relay for the starter check the voltage at the terminals of the relay from the switch to the relay and from the relay to the starter
check for fuses in the start circuit
if you have 24 volts every where then , pull the starter for a bench test by an accredited auto electrician

My 2001 Chevy Impala won't start. When I turn the key all ouside and inside lights comes on but that's it. No nothing else.

simple stuff 1st

  1. Check the battery for volts. You can have your lights but not enough to start. should read 12 or more volts. if not remove battery cables from posts clean posts back to silver color all the way around and charge.
  2. Clean the cables where they connect to posts till silver. Wire brush or file it
  3. reconnect and make sure there tight and try start
  4. if no start follow the battery cables and clean and tighten at starter and ground to frame.
  5. Try start
  6. no start then test solenoid and bench test starter.
Hope this helps Mike

Engine won't start. Cranks very slowly like it's on compression.

What are you working on? Make, model, etc. Check the wires for corrosion as they can cause symptoms of a weak starter. Also, was the engine acting irregular prior to the starter problem. Bad bearings can cause this too. Wouldn't hurt to bench test the starter. Just because its new doesn't mean it good. thanks

My alternator is not charging my battery, and both the aternator and battery are brand new and tested positive on the bench tests... Any ideas?

The early GM products would build up restance in the wire that went from the alternator to the starter. The easy cure for this is to install a 10 guage wire directly from the Alternator Batt. lug directly to the battery postive post. Do this using the correct end connectors.. do not just wrap the wire around the termanel. This was a big problem on these cars. especially the Diesel cars. Always disconnect the battery ground terminal before you work on this.

1998ford f150 starter won't crank or turn over.full charged battery.starter ingages when crossing small hot bolt with upper larger bolt.clicks with ignition.

First make sure you can turn engine over with a socket and that it is not seized. Second if engine checks out fine does the starter just click with the ignition key? If it does perform what is called a voltage drop test on the starter cables. Connect a volt meter on each end of the cable you are testing you should read no more that a half a volt drop when loading the circuit. If cables check out fine pull the starter and have it bench tested at an auto parts store. But be carefull bench testing can show a starter is ok with out putting a load on it, if it still shows good on the bench you still may need to replace it. If you don't get a click with the key check for 12 volts at the starter connector unplugged, if no trace starter wire noting color code back through the starter safety switch back to the ignition switch.

Have a 2004 saab aero 9-3. Recently battery died. It was shorted. But 6 years old. Replaced battery. Now often when trying to start, makes one loud click and won't start. Displays flicker and/or go black,...

I was having the same problem with my 2004 9-3. I assumed the starter was bad and replaced it. I then charged the battery and found it wouldn't fully charge. After charging for several hours when I removed the charger I only showed 11 volts at battery posts. The new battery tested 12.8 volts and the car started well. With the car idling I tested and showed 14.6 volts at the battery post which confirmed my alternator was charging.

I do believe I replaced the starter in error and that it was just a bad battery. When my battery was failing I had dim headlights and flashing displays that you described and the clicking noises also. When I put jumper cables on my saab and let the bad battery charge for several minutes the car would start right up and the headlights would brighten up and even though the battery was bad the idle voltage at the battery posts was increased to 14.6 volts coming from the alternator.

Remember to remove the jumper cables quickly once the car starts to avoid possible electrical problems.

I have had bad starters in other vehicles that would draw a huge load on the battery and jump starting them would sometimes give enough voltage to turn the engine over and start it.

Bench tests aren't always correct because the components aren't under a true load. I had a brand new alternator fresh out of the box last year that was bad and wouldn't put out good voltage even though it bench tested perfect. Go figure.

Check your battery voltage with the engine off. It should read over 12 volts if its charged.

Will not start

Have your battery charged and load tested to make sure it's OK. Then check the charging system and alternator drive belt for tension and condition. If car won't staqrt after charge, you may need to remove alternator to have it tested on a bench. Otherwise, put a volt meter across both terminals. With engine off, volts should be 12 or higher. Running should be 13,5-14V running with all lights, heater and A?C on should not drop lower than 12.8v.Low readings running indicate a bad alternator. If everything in charging system checks out OK, problem is likely in the starter or starter relay.

93 ranger not starting, wont turn over.

Take a volt meter and put the red probe of the meter on the engine block and the black probe on the battery Negative terminal. Have somone try to crank the car. If you get a reading of over 1/2 volt, you have a bad ground from the battery to the Engine block. Check the terminals on both ends of this wire.

If the above is OK, Put the volt meter on the battery terminals. (Red to Positive) and try cranking the car. If the voltage falls well below 9.6V your battery is bad. If 9.6 V or more, you may have somthing binding in the engine. When did this car run last?

Good Luck
