Is the injection time on the injector pump off?
It was not off, it was within the tolerance band where the control unit can drive the commencement of injection valve such that the actual injection time matches the specified injection time. Regarding cold start problems, the glow plugs and temperature sensors are ok ?
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
Where is the timing gear on a fuel injection pump?
The single dot on the idle gear should meet between the 2 dots on the timing gear. 8) Important: Be sure to check the pump oil after installation. Use 15W40 Rotella for both the engine and the pump. There are normally two small bolts on the back side of the pump that are used for fill levels.
How to install a fuel injection pump on a tractor?
Stop rotating as soon as fuel rises to the top of the #1 hardline port. 5) Install the pump onto the fuel injection pump gear and bolt pump to the timing gear case. 6) This procedure should get your tractor running, but some fine-tuning may be required to achieve optimum performance.

What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
How does a GMC Sierra 1500 fuel pump work?
The older model has steel lines coming off of the top of the pump to the frame rail and then connects to the frame steel lines with short hoses, you’ll need line wrenches and the ability to curse. The newer style has plastic tubes from the plastic pump casing and uses those quick connect fuel fittings and you’ll need the disconnect tool.
How much psi does a fuel injector pump use?
Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.
