My POS Blazer Won't Turn Over in the Rain

My 98 POS Blazer:

This week's problem:
Car won't start.


Battery is new, plugs, wires are all new.

Car has power, but doesn't turn over.

You hear it try to start, but never fully turns at the end.

Won't start in the rain or after it rained.


What could be the problem? Starter? Wires??

could be the battery cables, I had a bad ground on mine and it wouldn't start, just make sure the cables are tight, and make sure that the plastic on the terminal end isn't stopping you from getting good connections. I just cut mine off.

this was happening to my buddies jetta...there was just corrosion on the terminals...take a wire brush to it and see if itll start, then let us know how it went

battery is new.
Terminals are clean, make contact.

possibly the starter?

possibly the starter?

^^thats a good possibility, also im not sure but maybe check the alternator. again im not positive on that

probably the starter. I don't think the alternator would make it not turn over unless the alternator didn't charge the battery, causing the battery to run out of juice.

yea it cant be the alternator because he said its a new battery, in which case the alternator hasnt even had a chance to try to charge it...seein how its never been started with it..anyways, id say its the starter

Id say starter also, the best alternator test is when the car is running disconect the battery if it stays running the alternator is good if it shuts of go to the part store and get a alternator, im sure most people know that though.

Ok I dont say starter... all you need to start the car... power, spark and FUEL. ARE YOU GETTING FUEL??? If not, FUEL PUMP.

Thats my thought... if it cranks fine and no fuel... well, thats just my thought.

I think what Pat (hillbillyinohio) & Mike (MCas86) was trying to get to way back in the beginning was the contacts both at the battery and at the starter. If the terminals on the starter are corroded, you can get the same effect.

My take on the original post is that the starter is engaging, but does not have enough umph to spin the motor over. You do have to check all of the main things, but you also need the motor to spin to start it.

Update:

Seems the car will not start during/after it has rained.
When it has been sunny out for a few hours, it starts no problem.

I'm thinking it is a wire or something else getting wet.

Suggestions?

Please clarify.

By "not start" do you mean that it won't turn over or the starter just clicks (ie. crankshaft does not rotate)? Or do you mean that the motor turns over, but will not fire (spark or fuel problem)?

From your first post, I was under the impression that it simply wouldn't turn over.

thats the impression I got... why I said fuel pump. lol... hmm...could be wiring that has gone bad or gets wet.

The key turns, and it goes through the motion as if everything is turning, but you never get that last big rev before the engine finally starts.

my blazer did the same thing for a while. I finally replaced cap and rotor. that took care of it permantly. I would look into that. it would crank for ever and ever, and just not fire.

Cap, rotor, plugs and wires were replaced less than 3 months ago.

mine was replaced about 6 months proior to this. so it took me a while to look at that. who knows, worked for my truck.

Took it to a shop.

Turned out it was the coil.

Not completely true because mine was having problems starting because I did not properly crimp the wires when I swapped out my transmission which caused a bad connection which drained some of the power when I was trying to start. Jimmy rigged but hey once I crimped the wires right it worked like a charm.

The best way to test the altenator is to put a volt meter up to it. disconnect the altenator from the battery line and if it is putting out at least 12V then you are good (depending on the car of course)

Does it start after it sits there for about 10-15 minutes or so? If so, check out this thread:

For those who didn't read it the first time, his problem is fixed, it runs, no problem with his ride. Now on to the new thread that I about to start.
