My just shut off one day. But before it shut off, it was idling high. Then the A/C started getting less cool, the brakes started going bad too. Then it started getting harder and harder to start, then it just shut off in the middle of me parking. So we checked and it was my fuel pump. replaced it. Then upon checking further, my breather hose was missing from my air intake duct. Now the car wont even start still. It cranks but wont start at all. Please tell me what's wrong with my car.
Thank!

Hello,

An engine will need spark, fuel and compression to be able to start.

Does it crank strong?

So you will need to make sure that first the engine is getting spark to the plugs.
Take a look at this guide of how to check spark:

If you have spark then you will have to check to see if you are getting fuel and if it has correct amount of fuel pressure.
This vehicle should have 38-46 PSI of fuel pressure with the key on and engine off.

Please let me know of any questions.
Thank you.
