Why won't my van start or spark/turnover


You probably need a new battery. There is not enough capacity to turn the starter (which draws a lot of current); low current-drawing accessories (lights, radio, horn) will still work until the battery is flat out dead.

Why wont my car start?


Sounds like you have a power leakdown over night, after all night the engine and battery is cold causing the issue.
does the terminal spark when you connect it?? If so something is dragging power..
Check none of the accessories are drawing power when key is off e.g radio, cig lighter adaptors, interior boot lights ect....

Can the car alarm kill your battery but you can start the car but after you turn it off battey died again


sure, if you let the alarm drain the battery, this can destroy any stock battery.
The car batteries are not like golf carts and are not deep discharge rated. (so can be damaged)
so charge the battery, if it wont hold a charge, it is bad.
if it discharges silently, and darkly parked , that is phantom discharge
if is discharges , driving that is a engine charge system failure.
parked over night discharging is phantom discharging.
if the alarm goes off and stays in alarm , then dont use, it.
if the battery is happy with the alarm defeated then the Alarm is bad.

The battery measure 12.6vdc charged,(rested) "voltmeter"
and running measures, 13.3 to 15vdc at idle.

this one tool can solve this problem

My 2004 envoy will not start. A couple nights ago the lights on the dash were going crazy on and off. I would lose power on the radio and the dash gauges would lose power (fuel, battery, water) they...


Check the connections at the battery. Loose connections or corroded connections will cause this same symptom.

It is not uncommon for side terminal batteries to also have a problem internally between the mounting button (the place that the cable end bolts to) and the internal connection to the battery.

What sounds like what is happening is the connection is good enough to power up a light load, dash lights, gauges, radio, etc, but when a heavy load is demanded the connection heats up and looses continuity.

I see this issue more on fords but I have seen a fair amount of GM's with this issue.

Sunroof will not work


Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

The RAP relay is responsible for the radio and windows working after the igntion is turned off.

The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

(1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay(1) Park Lamp Relay

Car wont start but the lights, radio and everything battery operated comes on but it just makes a click noise when trying to start engine


If you can hear a click (quite loud) from the engine compartment, but the starter won't crank, this also could be caused by discharged battery. Battery problems - Discharged or dead battery is one of the possible reasons for a car not to start. Very common is the situation when we forget to turn the lights off overnight (the dome light, for example), which causes the battery to drain. In this case when attempting to start a car, all you will probably hear will be a clicking noise - there won't be enough power to turn the starter. Here is the simple way to check if the battery is discharged: Turn the ignition on. With the engine off, turn the windshield wipers on. If they move way too slow, much slower than usual, the battery is probably discharged. Also look at the dashboard lights - if they appear very dim, the battery is probably discharged.
If the battery is relatively new, it can be recharged. All you need to do is to boost your car and let the engine run for a while to charge the battery.

However if your battery is more than three-four years old, you will probably need to buy a new one. Sometimes, an old battery may even die with no apparent reason, even if the day before it was OK.

If the battery is OK, the starter solenoid, starter cables or the starter motor itself could be a problem.

Check it and tell us news.

1997 park ave battery dies over night


I just posted my experience in another place on this site but on my 1992 PA the accessories relay stuck closed. This relay is the one that allows you to listen to the radio etc and keep things on until you open the door then all shuts off. When it is stuck closed accessories keep running until your battery drains dead. The relay was replaced and all worked great.
