Hey, I have an 05 honda civic EX coupe. Car will not start unless throttle is pushed all the way.

Things that have been replaced since this problem started. Ignition coils, spark plugs, IACV, throttle body cleaned, Map sensor, air filter, Fuel pressure priming was seen at 40+, and fuel pressure cranking same 40+. Timing belt replaced and set to TDC. Injectors replaced. Compression 160+ all cylinder, o2 sensors replaced but replacing them gave me a code. Constant Misfire codes. There is gas in the car. It doesnt idle. No matter how long you hold the gas. Before it would idle if you let go of gas, but now its nothing at all.

Would appreciate some help.

 

Sounds exactly like the idle air control solenoid sticking shut, this happened to me, would only run with throttle, would not idle. I tried cleaning it but if I remember correctly I bought a new one.
