Have a proble with my 97toyota Tacoma 2.4l eletrical system bad relays/wiring from over loading with larger fuses. So no power to the starter when cranked power to dash with key out (oil and check engine light stay on) when key is on acc multiple issues with ex light signal/wipers.
I think it's a few relays osr and starter relay along with flashers? Also ignition and coil?
Also was getting no spark from distributer/plugs when jumping the starter. One more thing the engine would crank and pump fuel with key on and e brake pulled. After removing and reinstalling wiring with no sign on damage theirs is no more engaging of the fuel pump but still cranks with ebrake engaged.

 

Picked up oar and starter relay no luck same issue

 

Just what is wrong??

Having higher then recommended circuit protection will not do anything but allow that circuit to draw more current.

You need to work on one circuit at a time.

You should really try and find a copy of Toyota`s Electrical Wiring Diagrams. For your Truck

Go from there.

 

Not having any luck with it I have got the Haynes manual and going through it but these is no speciation a on where to sart on wiring shorts like most common at the ground wire for example and or not finding and issues of similar problems.

First time going over the hole engine and wiring is not something I'm great at so assistance is greatly appreciated. Thank for the rely

 

So going over the wiring now and could use a diagram of witch j/b j/c are located where I keep getting them mixed and about to throw some labels on them if I don't get one..

 

Throw away your Haynes manual. Seriously. It's about as helpful as a roll of toilet paper for the issues you're having.

You need to buy a 2 day subscription to Toyota TIS and simply download the entire FSM.

Electrical demons suck.
Good luck.

 

Hating this going to see mechanic but also can't work from the garage any more.

 

Update think I've narrowed it down to a faulty ignition module and a bad cell and starter relay also found a loose ground wire previous owner decide to leave hanging and rigged up I'm just getting no spark and no crank and relay is popping...
