Hi, welcome to Just Answer. I’m Ron and I’ll be helping youtoday.Before we get started though, Please understand that I don't knowyour skill level or tools you have to assist us. Also understand thatI can't see, smell, hear, or touch the vehicle either, so patience isappreciated. JA is a great Q/A site, but it does NOT replace arepair shop.My goal is to make you happy and get a great rating in return formy time. Sometimes I have to give you bad news that I know youdidn’t want to hear, so please don’t shoot the messenger.
Let's first check the fuel pressure with a gauge to see where we're at for a baseline. Also check for a strong blue spark at the plugs with a spark tester. Another item of concern is the engine coolant temp sensor. This part acts like a choke used to on older carbureted engines. It enriches the mixture for cold starting.
