Where is the crank sensor located is it hard to replace?

It's not either of the above answers! the only way to know would to have a No Start diag done on it this would include testing everything form the fuel pressure and more! most common is a fuel pump but to just pic something without checking it would be retarded I would suggest you take it to a shop and have a no start diag done on it or pick up an Haynes or Chilton's and follow the trouble shooting procedures to eliminate what it isn't!

I agree with everybody else. but it could be the Fuel Filter....not enough fuel.

The problem is not the crank sensor, if it was it would not start at all. If the car starts and shuts off as soon as you let go of the ignition key, you will need to replace the electical portion of the ignition swithch. Honda (acura) has alot of problems with the ign switches. The cost is approx 120 cdn for the part and about 1 hour labour to install( can easily be done yourself in the same amount of time) Hope this helps...

I don't think it's the crank sensor...mabye the TPS(throttle position sensor) or put gas in it.

I don't think there is the problem with the crank sensor,the problem lies with the ignition switch.So check it there properly it will be solved.
