The reason is because the fuse leaking or faulty makes the car won't start?

More than likely your wheel bearing if it increases with vehicle speed not engine rpm if it’s engine rpm it’s more than likely a failing pulley bearing

Hard starting but cranking

Honda Civic 2006 Hatchback  35000 miles
My car will not start but cranking after a day or 2 of rest. When inertia switch is pushed it will start luckily then when the problem persist and pushed the switch again nothing will happen. Car will not start but only cranking. Upon research, my inertai switch may need replacement bec it also served as a fuel pump cut off switch. I want this switch to be by pass but i need a wiring diagram to examine if my theory is possible and will work after by passing the inertia switch. Thank you for your assistance on my dilemma

GX model runs rough when very hot outside

Honda Civic 2009 GX 325000 miles
My Honda civic is a GX model. Runs on CNG (compressed natural gas). When it’s very hot outside, especially with air con on, it’ll run rough and occasionally stall. It’s like a misfire that gradually gets worse, then it’ll suddenly run smooth. After a bit it runs rougher and pattern repeats.

Installed backup camera - now car won't start

Honda Civic 2009 LX-S 145000 miles
I recently added a new stereo and backup camera to my Civic. I got everything to work correctly, but today noticed that the wire attached to the reverse bulb had popped off. So earlier today, i started to redo wiring in the trunk for the backup camera. The key was in the ignition and I had the key set to ACC. This is where it begin. Then out of nowhere, the "door open" beep starts. I try to start the car, and its not working. Current state: Battery has a charge, full tank of gas. Engine will turn over, but immediately dies - like its not getting any gas. Also, the dashboard is not displaying… Read complete

Car won’t start, no fuel, no spark, won’t read codes

Honda Civic 1996 Manual hatchback  99000 miles
The car has a b20z2 from a 99-01 CRV, a wiring harness from a 96-98 civic si. I’ve checked and cleaned all my grounds. Checked all my fuses and their good. Tried different ecus. It won’t read codes. The main relay works because I bought it new and it clicks. Bought a new wiring harness. New fuel pump.
