Question: 2002 Chevrolet Venture

My husband and I bought this van on 2/27/2014, we took it on a small test drive, it ran great. Super smooth ride, no engine noise, and shifted great. We left the car lot and drove about 5 minutes down the street to get gas and turned off the car, turned it back on about ten to fifteen minutes later and it idled rough. We turned it off and on again, it was running okay. We drove maybe 20 minutes and the car started to overheat, my husband changed the thermostat and tightened some super loose clamps while changing a few of the hoses. The van ran fine for a good hour drive, no overheating the dual fans wouldn't kick on but the temperature never made it over halfway, it was maybe 40' outside that day. We parked the car and everything was fine with it. My husband went to start it one afternoon and it wouldn't start. The fuel pump sounds like it's working, the spark plugs are fine, the engine cranks once. The security light came on but he got it to go out leaving the ignition turned on but not started ten minutes then back on. It died, he cracked the solenoid and it started but ran really rough until it died out. Then he replaced the starter , nothing. Then he put on an ignition push button (to start the van w/o a key) it starts but only while plugged up with jumper cables, when removed it dies after about 30 seconds. The trick/bypass of turning the key to on then waiting ten minutes and trying again doesn't work now, just that once. The key doesn't look damaged to be from the passkey so I really have no idea how to go about fixing this. The next and probably final thing we was going to try is replacing the alternator. Any help is greatly appreciated. TY

if the car will run with jumper cables hooked and dies when they are off means the alternator is not charging. You have a fuse in the under hood fuse box for the alternator. I would check that and all your fuses before I replace the alternator.

Car Brakes: How Do You Know When to Change Them?

By Zach Bowman For those who suffer a daily commute through heavy traffic, your vehicle's braking system can bring thousands of pounds of metal, plastic and empty Starbucks cups to a stop hundreds of times before you get to work. It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
