Hello everyone

Im new here, so i recently bought a crashed type r with airbag deployed.

Usually in those cases, you replace the negative battery cable sensor and it should start.

Did that, it doesnt start..

So, i was wondering if anybody knows if the fk8 have a fuel cut switch?

I checked all the fuses and evertyhing seems ok..

The car does start when i push it in second gear.

Any input ill really appreciated

Thanks

OBD scanner say anything? Never dealt with a crashed car personally.

A few things... will the car turn over? If not... immobilizer perhaps might do something weird on an accident where the SRS module registers the accident. If itā€™s turning over but not firing, my bet is thereā€™s an inertia switch that tripped. It kills the fuel pump so it wonā€™t keep sending fuel down to possibly ruptured lines and feed a fire. Iā€™m not sure if thatā€™s integral with SRS or not. SRS does more than just airbags... it also does the belt pretensioners. Iā€™d look at this possibility however. I have to finish a bibliography for college tonight and will see if I can find some details on our cars while Iā€™m on. Iā€™ll fire it back if I see anything.

Edit: if you plug in an OBD2 reader and the car is making no fuel pressure when the car button is ā€˜onā€™ (double tap) then Iā€™d assume this would point to this.

Another off thing is the... er... neutral safety switch/clutch switch. Whatever itā€™s called. If it failed in the accident, it wonā€™t allow the car to try and turn over, as the starting it or would try and move the car while in gear. It should be a physical switch under the clutch.

OP says he can push start it. Wouldn't that mean the fuel pump circuit is functioning, so my guess is it won't turn over with the push button. OP are you there?

Yep... I totally missed that line. So you can push start it in 2nd and it will run and idle fine?

(I did find the inertia switch on a Jazz for what it's [not] worth).

Most likely the fuel pump is shut off. It is a safety feature that is enabled when an accident occurs.

How do I know? I was drilled in the rear years ago and I had the exact same thing happen to my car.

First question, why did you buy an R that was in a state like this?" Usually, doesn't exist with this platform in this case.

"so i recently bought a crashed type r with airbag deployed.

Usually, is not the case. There are a ton of details missing that prevent you from driving that car away. Airbag, or airbags? front, rear, side, what was done to repair if anything?

Thanks ppl for all the input

You guys are right, i need to provide more information.

One, i bought the car from the auction with the intentions of restoring it and have some fun.

This is not the first car i restore, so typically with a crashed, airbag deployed car you just need to change the negative battery cable sensor and it shoudl work. (BMW cars)

This time, it is not that simple.

Car is hit in the front driver side, hood, fender, radiator support and headlamp are gone.. Apron is ok .

Steering wheel and roof airbag deployed, including seat airbag

Damage is not that bad to be honest.. well not for me..

Car runs and drives if i push it.. no overheating but my cluster looks like a christmas three..

I have follow the videos from rebuiltguy repairing a type r (youtube), but he doesnt mentioned anything about how he make it start again..

Then today i found this diagram item #18 (looks like an inertia switch)
https://www.hondapartsnow.com/parts...c-5dr-type-r-touring-ka-6mt/switch.html?PNC=5

Checked all fused on driver side kick panel and nothing..

Thanks again for all the input

I'd assume it's not an inertia switch since your fuel pump is working.

As to the instrument cluster being lit up, there are a few threads on here about cars that were still drivable but with front end damage that cut enough wires that are running around the bumper that it's going to make a lot of stuff go batshit. Checking out a few general "I wrecked by Civic" threads, regardless of CTR vs other trim might be helpful. Barring another good idea from someone else or something to bring an inertia switch back into play or something the SRS module does to prevent a restart (and I've never heard of that) I'd start with verifying that the starter and associated components aren't in some way faulty. Not sure where it's ground wire on a CTR's starter gets landed... but check to ensure it wasn't lifted when all those parts got pulled for some odd reason.

But the car isn't turning over when you push the button when stopped?

When you have the car rolling and pop the clutch and push the button you're turning the car to what a keyed car would be in the "On" position. I'd assume you'd start it rolling with the button double-pressed to on with the clutch not in... then get a push with the clutch in then pop it to let the momentum of the car turn the engine over. You'd do the same thing on a car with a failed starter.

If the car is turning over but not firing when you depress the button... it's another problem. Again, the safety switch under the clutch would also prevent the starting motor from turning.

I don't have a lot of knowledge of inertia switchesā€¦ only that your fuel pump shouldn't work w/it tripped. The whole point of it what (at least I thought) to secure your fuel pump so it wouldn't pump your fuel tank through a possibly cut fuel line in the engine bay or elsewhere on the car to feed a fire.

Good point, Ill check on the clutch sensor see wazup tonight

I will also recheck all the fuses in the kick panel

Ill check that switch on the pass side, it might be the inertia switch but not sure..
