Just replaced catalytic converter, exhaust manifold and o2 sensors on my car and now it cranks but wont start. Also, when I press on the gas the rpm's do not go up. Previously replaced spark plugs and crankshaft and camshaft sensors. Do not know what can cause it.

It sounds like you have knocked off the crankshaft angle sensor electrical connector. Can you please check it? Here is the location.

I had the same problem and the sensor was broken. I replaced it and now it starts up great.

Thanks for the help.
