GMC Repair: 1998 Chevy PU, battery gauge, amp meter


Question
I poured the gas in yesterday and still nothing, I checked the spark plugs and I was getting a blue arc. My battery gauge still shows that my battery is almost dead eventhough I bought a new battery and it was at 100% charge. In this model the voltage regulator is built into the alternator. -------------------------

I am in Oklahoma. I would try my amp meter,but it broke:P
I personally have replaced 2 taillight bulbs, a starter, alternator, 3 batteries, spark plugs, oil filter, and brakes(front and rear).
When I changed the battery the last time it was bulging on the sides if that helps any.
I had the starter and the alternator tested and they were fine. I checked all of the fuses and the relays all looked ok.
It's turning over just not starting.
It is getting fuel and fire, so i don't know what else to try :(

I bought this truck in 2000. From the time i bought it until now i have had to put a new battery in it every year, a new alternator, a new starter, and about every 6 mths it dies on me. The battery guage will show that it is almost dead. There has to be something that is staying on all the time, or something draining my batteries down. Do you have any suggestions for me? no one seems to be able to find the problem.
I have taken it to a few mechanics and still no luck.
Answer -
I'm NOT surprised that they can't find a problem. The trouble with people like them is that they are either DON'T CARE and or are to lazy or have no clue as to how to test for and find the problem.

Out of curiosity, WHERE is this truck at ?. As I am in New Mexico.


OK, If you have an AMP meter and know how to use it I can give you some basic tests to perform to help isolate your problem.

FIRST, I need the complete known repair history of the vehicle. EVERYTHING from a new transmission to replacing a light bulb.


Normal amperage drain on the battery when the vehicle sits overnight is !/2 amp (0.50). Anything above 1 amp is excessive.

let me know.

Answer -
A BULGING battery is a sign of overcharging by the alternator and or a fault within the battery itself.

How did you determine that you have adequate ignition and fuel ?.

Although VERY DANGEROUS, Try pouring about 2 ounces of gas into the intake manifold and see if the engine TRIES to start and BE CAREFUL DOING SO and let me know.

Answer
If your POSITIVE that you have adequate fuel PRESSURE and VOLUME and are also POSITIVE that you have adequate ignition to ALL the spark plugs, Perform a compression test on ALL the cylinders.

There is something that your not telling me here that has been altered with the vehicle or someone has tried to make some type of repair that is causing a DEAD short in the vehicles electronics or somebody has tried to install SOMETHING somewhere.

Your going to have to put an AMP meter in between the negative battery post and the negative battery cable to see how many AMPS is being drawn from the battery BEFORE we can continue.
