Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
today.
Before we get started though, Please understand that I don't know
your skill level or tools you have to assist us. Also understand that
I can't see, smell, hear, or touch the vehicle either, so patience is
appreciated. JA is a great Q/A site, but it does NOT replace a
repair shop.
My goal is to make you happy and get a great rating in return for
my time. Sometimes I have to give you bad news that I know you
didn’t want to hear, so please don’t shoot the messenger.

Let's check for spark at the plugs first with a spark tester, then check fuel pressure with a gauge and let me know the results.

Thanks, Ron
