09450-06501 PUMP ASSY, INJECTI Denso Cross

Do not use more than 55 kPa (8 psi) of air pressure in the fuel tank or damage to the tank may result.
Check for leakage at the connections between the fuel tank and the fuel transfer pump. If leaks are found, tighten the connections or replace the lines. If there are no visual leaks, remove the fuel supply line from the tank and connect it to an outside fuel supply. If this corrects the problem, the suction line (standpipe) inside the fuel tank has a leak.3. Low Quality Fuel: Remove a small amount of fuel from the tank and check for water in the fuel. If there is water in the fuel, remove fuel from the tank until it is free of water and fill with a good quality fuel. Change the fuel filter and "prime" (remove the air and/or low quality fuel from the fuel system) the fuel system with the fuel priming pump. If there is no water in the fuel, prime and start the engine by using an outside source of fuel. If engine starts correctly using different fuel, remove all fuel from the tank and fill with good quality fuel. Prime the fuel system if necessary.4. Fuel Transfer Pump: At starting rpm, the minimum fuel pressure from fuel transfer pump must be 35 kPa (5 psi). If fuel pressure is less than 35 kPa (5 psi), change the fuel filter element. Look for air in the fuel system. If fuel pressure is still low, install a new fuel transfer pump.5. Fuel Injection Timing Not Correct: Check and make necessary adjustments as given in the Testing And Adjusting section of this Service Manual.6. Valve Adjustment Not Correct: Check and make necessary adjustments as given in the Testing And Adjusting section of this Service Manual. Intake valve clearance is 0.38 mm (.015 in.) and exhaust valve clearance is 0.76 mm (.030 in.).7. Bad Fuel Nozzle(s): Remove the fuel nozzles and test as in the Testing And Adjusting section of this Service Manual.8. Low Compression: See Engine Misfires Or Runs Rough. Exhaust Smoke Cannot Be Seen While Starting9. No Fuel In Tank(s): Check fuel level visually (do not use the fuel gauge only). Be sure tank selection valve is open to the tank with fuel in it. Be sure valve in fuel line between the tanks is open.10. No Fuel From Fuel Injection Pump: Loosen a fuel injection line nut at the valve cover base. With ignition switch in the ON position and accelerator in the FUEL ON position, turn the engine with the starter to be sure there is no fuel from the fuel injection pump. To find the cause for no fuel, follow Steps (a) through (d) until the problem is corrected.a. Prime the low pressure side of the fuel system with the priming pump.b. Check the shutoff solenoid. Remove the cover on the governor and check the plunger. Plunger should be fully extended to allow full rack travel. If rack travel is restricted, adjust
