My vehicle listed above never starts in the morning. And after it has parked for a long time it takes long to start. I have been told I have been told by different mechanics that it's the injector pump and others say it's the compressor of the engine. They are telling me to do an engine overhaul but am skeptical because non of them seems sure.

This is unlikely to be a compression issue as you do not lose compression and gain it back as you are cranking the engine.

However, the way to know for sure is to test the compression when it is cold. Here is a guide that will help with this:

I suspect this is a fuel issue so again, we need to test that by checking the pressure using this guide:

Unfortunately we don't have a manual on this vehicle to give specifics as this is not offered here in the USA but we should be able to help figure out the issue with this info. Thanks
