if the intake sensor is having problems you could tell very quickly by unplugging it if it were just that or not but to really help you you would have to be more specific about what is happening to your car... if it will not crank then there are 3 things you need to look for
1 spark it has to have fire
2 gas it has to have fuel
3 air if it can't breath it will die
to check the spark take a plug out and lay it on the head DO NOT HOLD IT IT WILL GIVE YOU A LITTLE SHOCK

if it is sparking then go to the next one
fuel if you are thinking the injectors are bad or clogged then you can take them out and turn the engine over... if they mist gasoline... into a bucket or rag.... not just letting them spray... then check for the air
the only thing i can think of is that the filter is clogged or that the intake is clogged just take the top off the filter box and crank it up or turn it over if it will not crank and you have fuel spark and airflow then you may want to check the compression in your engine if it is below about 120 i'd say your piston rings need replacing badly normal i think is around 145 psi... any other input is welcome
