Fuel pump was replaced recently and I hear it whine when I turn key to on so don't think it's that.

@Deleted User If you're talking about wires then hell no they ain't clean, there's oil everywhere.

Deleted User 2018-03-16 18:02:00  

Maybe try cleaning off the contacts to make sure that the oil isnt impeding the flow of current

Deleted User 2018-03-16 18:05:13  

Starter could be bad

Deleted User 2018-03-16 18:05:18  

Seems unlikely though

@sigruna14 Check inertia switch

sigruna14 2018-03-16 19:31:54  

@John O - Is that like blinker fluid?

John O - 2018-03-16 19:32:44  

No, it's a safety device that cuts off the fuel line if you flip. As the vehicle gets older, they become more sensitive

John O - 2018-03-16 19:33:50  

It's just a spring loaded normally closed switch. You can test it by pressing the button, and if the car starts and then stops, it's the switch

sigruna14 2018-03-16 19:36:23  

@John O - But if that switch were tripped, would I still hear the fuel pump whine when I turn the key to on?

John O - 2018-03-16 19:36:33  

Yeah

John O - 2018-03-16 19:36:59  

It stops the fuel line, not the electrical circuit going to the motor

John O - 2018-03-16 19:37:37  

The intention is that if the car gets in an accident, the fuel line doesn't pour all over you if the hose breaks

sigruna14 2018-03-16 19:40:24  

@John O - Where is the reset button? I Googled it but nothing definitive.

John O - 2018-03-16 19:40:40  

Consult the owner's manual

John O - 2018-03-16 19:40:50  

It was under my dash in my old truck

John O - 2018-03-16 19:42:03  

Or just Google "your vehicle inertia switch"

John O - 2018-03-16 19:42:42  

The reset button is on the switch

John O - 2018-03-16 20:55:17  

@sigruna14 You get it?

sigruna14 2018-03-16 22:00:27  

@John O - The internet seems to think this car doesn't have that. I just gave it to the shop to diagnose. I'm tired of dropping dough and screwing with this damn thing.

sigruna14 2018-03-16 22:02:06  

If I keep replacing things hoping it'll fix pretty soon it will basically be a whole new car. Anyway evidence seems to point to wiring or computer. Either one is pretty much beyond me I think.

sigruna14 2018-03-16 22:02:44  

I replaced the computer three years ago and if it's that then idk what to do, maybe it needs flashing or something. I just got one from Advance and threw it in, seemed to work fine until now.

John O - 2018-03-16 22:18:48  

What kind of car?

John O - 2018-03-16 22:19:11  

I'm just curious at this point

Freiheit - CA 2018-03-16 23:47:54  

Inertia switch is often by rear left tail light in the trunk.

Freiheit - CA 2018-03-16 23:49:42  

...here's a video for your car I think https://m.youtube.com/watch?v=KFuE31wFgE8

Freiheit - CA 2018-03-17 01:05:21  

Nvm...not helpful.

Tanner - SC 2018-03-17 06:01:28  

John, he posted earlier that it’s a 2001 Caravan 2.4L 4-cyl.

John O - 2018-03-17 12:21:53  

Yeah, what brand

RevStench 2018-03-17 13:00:53  

Dodge/Chrysler in 2001

Deleted User 2018-03-17 14:42:47  

Crank problem is almost always fuel issue for me siggy

SamanthaM 2018-03-19 14:19:41  

Quick question. Does anyone have a good book they would recommend on the basics of automotive mechanics?

Deleted User 2018-03-19 14:22:42  

Haynes Repair manuels. The Bible for any DIYer.

Deleted User 2018-03-19 14:23:38  

Many a man tore his knuckles to bring us the glorious Haynes Manuels.

SamanthaM 2018-03-19 14:34:05  

@Deleted User Perfect. Thank you. And this is an overview of everything I'll need to know?

SamanthaM 2018-03-19 14:34:43  

Does this cover most modern cars? Sorry, completely illiterate on the subject.

Deleted User 2018-03-19 14:36:13  

Yes and you can purchase them at any autozone, napa or cookie cutter parts store.

Deleted User 2018-03-19 14:36:55  

Yes, everything. From routine maint to changing out A-frames.

Deleted User 2018-03-19 14:37:03  

It has it all.

SamanthaM 2018-03-19 14:39:42  

Great. Just picked it up on Amazon. Thanks! Love how they're specific by model/year.
Second question. Is there a basic book on how engines work?

Deleted User 2018-03-19 14:40:55  

I dont have a good rec for that other than Youtube.
