Engine is hard starting?

Hi:
What you need to do is check for fuel pump pressure drop off. When you turn the key on, there should be pressure. WHen you shut the key, it should hold pressure for some time. WHat you need is check for fuel pressure drop off when you first shut the key. IF it drops off right away, that is why it takes time to repressurize the system and longer to start.

Here is a how to for checking fuel pump pressure and drop off. Check it and let me know what you find.

Check firing order, make sure its firing on all cylinders

check for excessive fuel in cylinder and on plugs
check fuel pressure regulator

remove O2 sensor before catalytic converter and check exhaust back pressure
if high suspect clogged catalytic converter

This is something that is going to require some troubleshooting to find the cause. When the problem happens is when it can be tested. I suggest making an appointment with a shop you are comfortable with to do the testing. Set up an appointment so that when you show up, the problem will be present and the diagnosis can be done. Make it clear that when you get there you want it checked at that time because that is when the problem is present. They should be expecting you and you should be prompt. May be a spark, fuel or timing issue. Needs to be diagnosed.

Is the starter turning the engine at a normal speed? Is it always hard to start? Has the check engine light come on? Has fuel pump pressure been checked?

Check fuel pressure first.

Start there

Good job

Could be the battery itself or loose connections also the starter relay-start here

Good afternoon,

Does the engine crank over when it will not start?
