Can't prime my saanyong musso diesel


If vehicle has a MERCEDES MOTOR fuel distribution comes via common rail system, diesel is drawn from tank by high pressure pump and fed to injector rail. FOR any reason if rail pressure drops injectors will not open .Possibility that fuel line has air lock or leakage. Diagnostic equipment will be required to solve certain engine management malfunctions.

Air lock in saab fuel injector


I've never really heard of an air lock in a fuel injection system.
The computer opens the injectors and the electric pump in the tank pushes the fuel to the engine.
Have you checked fuel pressure at the injectors with a gauge to see if it is normal ?

I have a 2002 Chevy Blazer. It died driving down the road. I thought I was out of gas. I have since replaced the coil, the rotor and cap on the distributor. I have spark. I used a fuel pressure tester and...


First will it fire with the aid of fuel inducet to the engine? There will be a breather hose attached to the intake near the throttle body. remove and use a carb/ throttlebody cleaner spray, have someone crank the engine and spray into the hole going into the throttlebody using the straw that the cleaner comes with. if it fires then the engine is not getting fuel. fuel pressure should only be 60-66 psi. Sounds like you have a faulty Fuel injector spider assembly. The regulator IS replaceable, you have to be VERY careful if you want to try that first. the assembly is plastic type of material and gets britle.and brakes EASY along with the injector lines. I will usually just replace the whole assy. as if it is not the problem and the injector is you have to go back into where you already were again.

2000 GMC Jimmy 4.3L CSEFI won't crank. Fuel pressure is 50psi and should be between 55 to 60psi. Fuel filter 1yr old and fuel pump is probably stock & needs replaced but never had problem before...


Check your starter and check your connections to make sure they are clean and tight. The low fuel pressure won't cause a no crank. Too low could cause a no start but not a no crank. I've had starters be bad right out of the box. But if that starter motor isn't turning either the starter motor is bad or the solenoid attached or the wiring to it is at fault.

Looking for fuel pressure rgulator for efi 4.3 v6


It should be connected on the fuel rail or on the end of it. It's round in shape and has a small vacuum line connected to the top of it.

Where do i find the fuel pump regulator on a 1997 astro van with 4.3 vortec v6? Is it replacable or ajustable?


depends on the type of fuel injection on the motor... on the CSEFI injector assembly the regulator is located under the air intake plenum on the back of the fuel meter body

Fuel injector replacement goes horribly wrong.


We had the same problem with a 95 Jimmy, Drain your oil, and if you get more than 5 qts it means the injection system failed and filled the bottom half of your motor with gas. You can simply check the level on the dipstick and smell it first before draining. We drained and replaced oil and filter, and the expensive injector assembly, but the motor only lasted 4 months after that and now I am replacing the motor in it. Check around to see if there is a product on the market to save the bearings in your motor before going through all the expense and work. Happy motoring.

1996 GMC JIMMY won't start


I think 54 p.s.i. on fuel pressure is close to border line, Are the injectors pulsating, You can have fire at the plugs but if injectors are not pulsating it will not run. I know there were problems with the injections systems on blazers and jimmys around that year, i would look closer to the injection system.

No start


NO, it will not cause an air lock in the fuel system. It can cause a hydraulic lock in the affected cylinder however. A leaking fuel injector or a leaking injector cup can allow air to enter the fuel system.
