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 5 months ago.

what kind of work were you doing in that area?

Customer: replied 5 months ago.
There was some damage to the body metal... I was pounding it out.
Customer: replied 5 months ago.
Not the fender, the body around the engine compartment
Expert:  david craig replied 5 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 5 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 5 months ago.

you probably knocked something loose with the banging

Customer: replied 5 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.

Customer: replied 4 months ago.
Replaced battery terminals and relays and vehicle started. Suspect short at battery terminal, and the vehicle's CPU cut power... Safety feature?

i believe its called a circuit open relay

Customer: replied 4 months ago.
Might have been helpful to mention that before.
Expert:  david craig replied 4 months ago.

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

Expert:  david craig replied 4 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 4 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.
