Runs rough, won't idle, lurches, can't go faster than 25 mph. Replaced TPS & IAC Valve........No Change....Truck is on side of the road and I don't have OBD codes....Fuel pressure ? Ignition ?

CPI 55-60 psi @ schrader valve rear of engine. AND IT SHOULD HOLD PRESSURE WHEN KEY IS TURNED OFF!!! If it does not then the fuel spider is the likely suspect! Need a tow in that case. Black smoke from T-pipe?? Light on?

What is the 8th digit of the VIN. If it is W fuel pressure should be 55 to 60 psi. If it is a Z fuel pressure should be 6 to 9 psi.
It's a Z..So the fuel sys. should hold press when key is off...If it doesn't...Spyder is located ? SURVEY SEZ...Under INTAKE MANIFOLD ???
