Where is the fuel pressure gauge on a C4 Corvette?
Where is the fuel pressure gauge on a C4 Corvette?
On ’85-’96 models, connect a fuel pressure gauge having a pressure relief valve to the pressure test port on the engine’s fuel rail then, open the relief and vent the system into a container which can hold at least a cup of gasoline.
What do I need to know about C4 fuel injection?
Watch for oil vapors coming out of the PCV valve port. If you have oil vapors coming out of the PCV valve port in pulses like a steam engine, you have broken piston rings or possibly a broken piston. A light amount of smoke (blow by) without rhythmic pulses is normal on high mileage engines.
Do you have to drain the C4 fuel tank?
Old habits die hard so service manuals still say to drain the tank prior to a sender change. With C4 senders going into the top of the tank, draining is not required to change them. Getting the fuel out of the tank and storing it safely are difficult tasks.
Where is the gas pump on a C4 Corvette?
06: A gauge without a pressure relief is available from Zip Products, but the process is a little different. Hold the gauge over a drain pan, loosen the fitting at the gauge then drain the gasoline into the pan. 07: The 1984-1996 C4 Corvette’s electric pumps are easily accessible from the top of the gas tank.
How is the c4.4 diesel engine electronically controlled?
Introduction SMCS Code:1000 The C4.4 diesel engine is electronically controlled. The C4.4 engine has an Electronic Control Module (ECM) that receives signals from the fuel injection pump and other sensors in order to control the electronic unit injector. The fuel injection pump supplies fuel to the high-pressure manifold (Rail).
What was the first C4 fuel injection system?
C4 Fuel Injection Overview. Speed density was the first fuel control system used on 1982-1984 Corvettes. It was also used on the 1990-1993 cars. Speed density uses a manifold absolute pressure sensor (MAP sensor) to calculate the necessary fuel load. The 1990-1991 cars have a MAP sensor bolted directly to the intake plenum.
