Hi, welcome to Just Answer. I’m Ron and I’ll be helping you
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.

We need to confirm what we are missing when this happens to you. Fuel pressure needs to be correct, spark needs to be present at the plugs and power needs to be going to the injectors. let me know your findings.

Thanks, Ron
