02 Nissan Quest - Starting problem....when it sits

[sharonj_1017]

briefly, it sometimes won't start back up...? but when it sits all day or overnight, it'll start just fine. Mainly it is occurring when I run a quick errand (go into a store for less than an hour or pick up my daughter from daycare). When I turn the key, the motor turns over, but weakly (as if the battery is dying) and doesn't actually start the van. It starts up fine if I get a jump (and then I also don't have the problem for a few weeks after getting a jumpstart). But when it sits overnight, I never have this problem (which makes me think it's not the battery!). Starter? Alternator? Something else?

Sounds like a draining battery. Have it check, including post and cables------before it does not start at all.

Check your idiot light or Check Engine Light if it comes on have it tested at most any car parts store. It may be anything from alternator, coil pack, electronic control module, or plenty o different sensors could cause the problems your talking about, definitely something electronic so your best bet is to have it tested so you don't keep putting extra money in it trying to figure out the problem. Most electronics are not refundable. Each component can be tested battery, starter, alternator,coils, most anything electronic. Start with battery.
