Nissan Sentra Spec V won't start - help please.

[Inkedupally]

I'm having issues with our 2003 Nissan Spec V. When I bought the vehicle I was informed it needed new struts/shocks. However, I wasn't able to fix it right away due to money. The vehicle has slowly been breaking, and now it is at the point it no longer runs. We've replaced the battery, a new exhaust, tested the coils with good ones but they're okay, looked at the ECM and the padding was removed due to its recall and it looks to be in good shape. When I ran codes on the vehicle it stated that it was a misfire, cylinder number 3, and the throttle body position censor was showing in error. I have some people suggesting its the ECM still or the throttle body. The last thing I want to do is spend money that I do not need to. What would you suggest I do?

We've also replaced the crank shift censor.

have you checked the spark plugs at all?

I suggest you check out the fuel pump. The fuel pump sometimes loses the prime to the fuel throttle body. Let the fuel pump rum a 20 seconds or more to build it back up. If you have changed all those components you might be looking in the wrong place.
