Need your help: I have no electrical power at all

[reno808]

I used electrical cleaner spray on the maf sensor and connector because i got a code figured i clean it and give it a try. A few ppl on here said it worked. i put the key in the ign on the acc pos played with the radio for a sec and when i turned key to the on pos. i think i heard a pop and all the power cut. i have no power what so ever. i have checked all the fuses by the door panel and the by the ecu. Is there like a main power relay or fuse i'm missing?

Thanks for your help

Did you wait a few hours to let the maf cleaner fully dry? If you put it in wet and started the car, you could have short circuit your ecu, frying it.

Check all relays inside the ecu again

Maf cleaner dries really fast, I think it would be unlikely that even if it was still wet that it would fry the Ecu. If anything probably a fuse/relay you missed.

Fast dry or not, its very likely that moister will fry the ECU

Ask me how I know. Always wait a few hours

Solved update: This is pretty bizarre. I noticed that the neg post/cable was really HOT so i disconnected the battery. I then test again all relays and fuses, also tested all cables continuity it was all good. So my dad popped the battery back because he thought i didn't see it, boom everything worked like if nothing happened. super weird.

Ah ok. Not bizarre at all actually.

Your battery post was hot due to arcing, which is due to poor contact or high resistance due to dirty contacts. Clean your battery posts and make sure the terminals are seated nice and tight :)
