Welcome to JustAnswer!!! My name is***** will be helping you with your question today...

Expert:  -Brad- replied 14 days ago.

When it's hard to start can you test fuse M25 and tell me if it has 12v? This is a common issue and if you don't have voltage then reply back so I can tell you how to fix it before it leave you stranded..

Talk soon,

I have no way to check voltage but the fuse is good
Expert:  -Brad- replied 14 days ago.

If you want to fix this yourself then I will need for you to grab a test light and see if the fuse has voltage when it will not start..

Talk soon,

Are you going to test it? Also are you asking your question here to get an idea on what could be the problem or are you going to be repairing this yourself?

Customer: replied 13 days ago.
Repair myself if simple repair
Expert:  -Brad- replied 13 days ago.

Thanks for the reply!!

Ok if you can see if the fuse lights the test light when it will not start I will be able to tell you how to fix it. I see that you replaced the fuel pump and to be honest the OEM pump was most likely good.. You will be able to fix this yourself if you have a solder iron and about 30min.. We sell a kit to repair this..

Let me know what you find,

Does the switch need to be on when I check 25?
Expert:  -Brad- replied 13 days ago.

The ignition switch? Yes you need to be cranking it and the engine needs to not be starting when you test it.. Yiu may not be able to do it today if it's running fine.. But when it won't start have the test light ready and see if M25 has voltage.. If it doesn't then your fuel pump is not coming on which is why it will not start.. I went ahead and attached the bulletin describing what is going on and how to fix it..
