Customer Question

Hi... Turning the key to on the oil and check engine light come on. When I attempt to start, lose all power... everything is dead... no starter click... nothing
JA: Does the light stay on, or does it blink?
Customer: Which light?
JA: What is the model/year of your Toyota?
Customer: 1999 Toyota corolla
JA: Are you fixing your Corolla yourself? What have you tried so far?

Expert:  david craig replied 10 months ago.

what kind of work were you doing in that area?

Customer: replied 10 months ago.
There was some damage to the body metal... I was pounding it out.
Customer: replied 10 months ago.
Not the fender, the body around the engine compartment
Expert:  david craig replied 10 months ago.

have you checked for damaged wire or losse wires at the fuse box. postive battery power cable going into the fuse box? loose ground?

Customer: replied 10 months ago.
I checked the ground connection in the passenger side fender - cleaned contact area and wire terminal with wire brush and reconnected with dielectric grease. Checking battery cables now. There is an "Engine Main" fuse that doesn't look great, and I will replace. Battery terminals could use some work too... but don't understand why everything would cut out, and then reset after disconnecting and reconnecting the battery.
Expert:  david craig replied 10 months ago.

you probably knocked something loose with the banging

Customer: replied 10 months ago.
Something like what? Before starting, the headlight and turn signal/parking light work properly. When the key is turned there is one loud click, and nothing. All the fuses are really tight - difficult to remove. Will replace the battery terminals, and maybe the fuse box this weekend. When I remove the fuse box, may be able to see evidence of a short under the fuse box.

check voltage at the starter relay

Expert:  david craig replied 10 months ago.

any update?

Customer: replied 10 months ago.
Replaced battery terminals and relays and vehicle started. Suspect short at battery terminal, and the vehicle's CPU cut power... Safety feature?

yeppers

Expert:  david craig replied 10 months ago.

i believe its called a circuit open relay

Customer: replied 10 months ago.
Might have been helpful to mention that before.
Expert:  david craig replied 10 months ago.

i said i believe it is. let me find out for sure.

Expert:  david craig replied 10 months ago.

there is a circuit opening relay. when you go 2 days without responding or updating so we can continue troubleshooting ...cant get back in the groove with that kind of lapse.

Customer: replied 10 months ago.
As I said, mentioning a circuit opening relay before would have been helpful... moreso than suggesting 'all the banging may have loosened something". No shit, Sherlock. I figured it out, thanks.

you're the one who screwed up your vehicle. not me pal. any ways i m glad you got it fixed.
