#145 of 381 1996 Chevy Suburban Killing Batteries
May 17, 2009 (4:25 pm)
I have a 1996 Chevy Suburban 4WD (no turbo engine), and I have been replacing batteries time and time again.....I have taken the alternator to Auto Zone for testing, and it passed. I think that my truck is still a good truck, and I want to try and fix it (it is my fishing/work truck !), but I do not want to toss a wad of money into a (possible) electrical problem-which is WAAAAY beyond my mechanical expertise.
I had a Chilton manual for my truck, but I have misplaced it (UGH !)............
Could someone share some of their mechanical prowess ?

Well either the alternator isn't charging it, or there is something draining it down.
Normally you would drive the vehicle to an autoparts store, and they would check the alternator under load with the engine driving the alternator. I had a 97' and went thru 2 alternators over 10 year period, so I'm personally suspect of the alternator. What you may want to do, is drive your vehicle over to some different parts center, and get a 2nd opinion on the status of your alternator (while it is in the vehicle).
If the alternator checks out okay, then you need to put a test light on the current draw off the battery, and start unplugging fuses to find out when the current draw stops. Something could be sitting there with a constant couple amp drain and draining the battery down. Start w/engine off, key off, and try to figure out if there is any current draw, and if so, which fused circuit it's on.
You could have a relay with fused points, providing voltage all the time to something that shouldn't have power when you turn the key off.
#147 of 381 Tahoe won't start unless hot?

I know this is over a year old, But I am having the same problem with My Tahoe, Won't start unless it's sitting in the hot sun. I took it to 3 mechanics including the dealership and they all said come and get it, we can't fix it.
I was wondering if you ever solved the problem?

I NEVER found a "reason" for the discrepancy, but, I put the starter back in,..and it has been running well ever since.
Anyway, now, I have to replaces the rotors/brakes on the front end - it is metal-on-metal now
I hope you find a fix for your situation, and maybe, you will pass the findings on
#149 of 381 Crankshaft Position Sensor
Jul 09, 2009 (1:13 pm)
I just replaced the Crankshaft Position Sensor on my 1999 Suburban, 4wd, 1500, gas, not diesel. It was kicking back and grinding yesterday when I replaced the starter, but once it started, it purred beautifully. Shimming did not help. Now that I've replaced the Crankshaft Position Sensor, the car sounds great while it is trying to start... sounds wonderful compared to yesterday... like a brand new car. But it won't start. It's must be from replacing the sensor. The fuel pump is working great, new distributor and all. Does something in the computer need to be reset at the dealer or at a shop?

My fuel pump module on the 1999 Suburban finally died last week. I replaced it with an aftermarket Bosch unit, which at $250 was less than half what the dealer OEM pump cost. I replaced the fuel filter at the same time. Now our gas gauge is working again, a side effect of replacing a bad pump. Compared to the 1993 Chevy Astro we used to own, the quality of the fuel system components has gotten cheaper and more prone to fail.

I mean we have changed everything that deals with the ignition that we can think of. The suburban still won't start if it gets warmed up and we shut it off. What are we forgetting? Anyone have a clue?
#152 of 381 97 Chevy Suburban starting issue
Jul 29, 2009 (5:04 am)
I have a 97 Chevy Suburban that has developed an intermittent starting issue. The past few days when I go to leave work, I'll put the key in, turn it and nothing, although the dash lights and the radio will come on. After a few minutes of turning the key off and on, it will turn over and start right up. It has been starting fine in the morning, but I'm sure at some point I won't be able to get it started. Any ideas short of replacing the starter?

Hang a fused test lead off of the +wire going to the starter solenoid. Put a voltmeter on that wire, so that you can watch what the voltage is when you are trying to start. If you have voltage there when you turn the key to the start position, then the problem is either solenoid or starter. If you don't have voltage, then your problem is between your ignition switch itself and that wire.

I'm beginning to suspect this may be related to the key. I switched to my spare set of keys and haven't had a problem since. Just a guess, though.
