95 honda civic ex squeals when starting engine

The timing belt is wrapped around the crankshaft and camshaft sprockets in the engine assembly.

Get diagnostics done , obd

Sounds like your starter motor went bad. That will definitely cause the engine not to turn over.

Hi
Your thermostat is located under a metal housing on the engine, which is where one of the radiator hoses attach to the engine. The housing is held in place with 2 bolts.

95 civic coupe ex brake lights wont work and the shifter locks in park position, what's wrong?

DID YOU HAVE SPARK IN THE SPARK PLUG WIRES WHAT YOU CAN DO IS TAKE OFF ONE OF THE WIRES FROM THE SPARK PLUG AND PUT A FLAT SCREW DRIVER INSIDE THE WIRE AND PUT IT CLOSE TO THE METAL SO THE WIRE GETS GROUND AND HAVE SOME ONE TO CRANK THE ENGINE AND YOU GOING TO SEE THE SPARK IF YOU DONT SEE SPARK SO THAT IS YOU POBLEM

I would talk to who cleaned the injectors, I don't know if it something they did or not. It could be a stuck open injector. The exhaust would have a raw fuel odor if it was. What it sounds like is a blown headgasket, which can just happen. The exhaust would have a sweet smell to it. Usually starts as a small leak (between cyl. 2 & 3), the engine burns the coolant while driving which you don't see. Then the coolant level gradually drops to a point where the car overheats, which warps the head, causing a large leak. Now you see the coolant burning (white smoke).
Good luck Honda Al

I would suggest you check your drivebelt/fanbelt tension and waterpump.

clean your air filter and try it .... normally on CNG at low Rpms it has unstable running

On the emissions tag under the hood but anyway it's a 2.2 Litre
