Hard starting, when its running it runs great?

Hi,

Chances are you are correct. Try this and let me know if the engine starts normally.

1) Turn the key from off to run (engine off) and count to 5.

2) Turn the key off and repeat step 1 a total of 5 times.

3) On the 6th cycle of the key, see if it starts normally.

Let me know.

Joe

No, no difference from what it was doing it will start to go and drop back to cranking.

Here's one had it running and took a quick ride an hour ago but it would only crank doing normal start so i thought try it in neutral cranked right up but after ride it's just hard cranking again.

Hi,

Based on that, I would recommend testing the fuel pressure to confirm it is within the manufacturer's specifications. We may simply have a weak pump.

Here is a link that explains how it's done. You will need a fuel pressure tester, but most parts stores will lend one to you.

I attached the manufacturer's pressure specifications below. Try this and let me know what you find. Additionally, when the key is turned to the off position, see if the pressure drops quickly.


Joe

See pic below.

Thank you. I'll let you know.

Will a scan reader say your fuel pumps are bad? I'm ready to go buy a new one already.

Hi,

Some scanners can, but not all. You need to make sure that the one you get can read live data and is bidirectional. In other words, you can have it communicate to the vehicle as well as have it communicate with it.

Let me know.

Joe

i bought a new battery camshaft sensor still nothing.

i did a scan no codes came up.

Hi,

When it won't restart, see if it starts if you use starting fluid. I there is no change, see if there is spark at the plugs.

Here is a link that explains how to check:

We need to determine if it is a fuel pressure issue or an ignition issue.

Let me know.

Joe

It does start with starting fluid.

If that is the case, then the engine isn't getting fuel when it happens. I need you to check fuel pressure when this happens. If it is low, the pump is the likely problem. If it is normal, then we need to see why the injectors are not providing fuel to the engine.

I attached the directions above for checking pressure. Let me know if you have questions or if I can help in any way.

Joe

I'll let you know tomorrow getting a fuel pump.

Hi,

Before you go to the trouble of purchasing and installing the pump, I would confirm that is where the problem is coming from. However, that is your call. LOL

Let me know.

Joe

Okay, how do i do that i can't drive it anywhere i have no pressure tester.

Hi,

Is there anyone that could pick one up for you or take you? Other than that, I'm not sure what to say. I just don't want you to spend the money, do the work, and then find out the pressure was good.

Joe

I agree.

Let me know what you plan. We need to get this thing running properly. LOL

Take care of yourself,

JOe

okay, here is were i am at: i can get it started with starting fluid and will stay running but the idle will be normal then drop down for a couple seconds and go back to normal, but when i give it gas there's is a lag for a second then it will rev a little bit. oh yeah, i also replaced coolant temperature sensor.

Hi,

Have you tried cleaning the throttle body?

Also, have you been able to check fuel pressure?

Let me know.

Joe

No pressure tester and I haven't cleaned the throttle body yet.

Just out of curiosity, try cleaning the throttle body to see if that changes how it runs. It may help out more than we think.

Let me know.

Joe

I'll do that.

problem solved, it was the fuel pump.

Hi,

Thanks for the update. I'm glad to hear you found the problem.

Take care of yourself, happy 4th of July, and feel free to come back anytime in the future.

Joe

Thank you happy fourth to you.
