Week ago batteries died, jumped it and headed to fuel up. On my way truck completely died...no sputtering or anything. Changed alternator a month ago, batteries are a year old. So I thought I ran out of fuel. I put in a few gallons, primed it and tried giving a go. Nothing, figured I loss prime so changed all of the gaskets in fuel filter head. Truck started 3 times but wouldn't stay running. After the 3rd time it out even run. Getting fuel to the rail but not sure about injectors. Not even sure if its a fuel issue or not anymore. Mods are as follows, stock tuning by moonshine(edge cts) , straight piped stock exhaust and 6in lift. Any ideas please before I go dumping money.
