A direct correlation exists between the amount of oil flow through an injector and the amount of fuel flow out the tip of the injector into the combustion chamber. Check service records for correct oil type and viscosity for the vehicle operating temperature. Chassis Style: Helpful for evaluation of performance or fuel consumption complaints. For additional mounting options see 98004 adapter below. Acceptable levels could be described as a puff of smoke followed by very light white smoke for the first kilometer mile or so.
Crank the engine and observe the fuel flowing into the container. Purpose To determine if engine lube oil is being aerated and causing poor idle quality. You can expect better tunes, better performance gains level for level and better drivability from an Edge Revolver chip than any other chip around for your 7. It ran this way for about 3 weeks when one morning I get in and start it long cranking then started and ran fine and get about a mile down the road and the truck steadily lost power and died, coming to a rolling stop. Purpose To test individual power cylinders and injectors to determine if all are contributing equally to engine performance. The low power complaint cleared as the converter self-cleaned. It may be improperly diagnosed as a rough idle complaint.
This will perform step tests on the injection control pressure system and the exhaust back pressure system. It does not call for service action unless it is dripping. One to lubricate the engine components and the other to operate the fuel injectors. The check valve internal to the pump is not serviceable. Refer to the lube oil chart below to select the correct viscosity oil to use for the temperature condition s the engine will be operating in.
If this fluctuation is visible on test equipment, ignore it. System Faults: 0236 Detected high boost signal at low idle. Yes that is alot of amps so be sure your battery and charging system is up to par. A leaking nozzle sleeve or injector tip may cause fuel to contaminate the engine oil but may be identified as a performance problem. The right side of the form provides the technician with the procedures to diagnose a performance complaint examples listed below. Lube Oil Chart The oil level reservoir should also be checked. The surface of the exhaust side should have a sooty appearance.
If the light is illuminated, the fuel may be contaminated with water. Chassis Style: Helpful for evaluation of performance or fuel consumption complaints. Engine speed is one of the controlling variables in the calculation if desired injection control pressure. If the tang is positioned as shown in the exhaust butterfly valve is opened. Also See Circuit Breaker 12. Make sure trapped air is purged from the high pressure system by running the vehicle hard for 20 minutes after a repair to avoid false codes.
Also See Circuit Breaker 12. I assume that the 30 amp fuse under the steering wheel has not blown otherwise it would never start. There's no need to wait for reprogramming like hand held tuners. Lamp that indicates to the operator when the glow plugs have been on long enough to crank the engine. If you have only 3 glow plugs working and you use starting fluid on it you are going to cause engine damage very quickly. Operational Signal Checks These checks are made with the breakout box installed and are normally measuring a signal voltage or frequency. The tests on this form will discern if the essential elements required to start are present e.
Start looking for the leak at the top front of the engine and work toward the rear and then down the back of the block. Procedures This condition assumes that the reservoir was full when the engine start was attempted or when the engine started normally and would stall after 15 seconds of running. It is a silvery tin box with a wiring … harness running into it , but before you attempt to remove it or unplug the wiring harness disconnect your battery on the 1997 sunfire take off front passenger side tire pull off inner fender guard i believe there's one screw other are pull plastic retainers some will break and need replacement remove passenger headlight, it has two fasteners tow screws for module will be accessible under light, other screws will be from under neath, then you can pull and unplug automatic? The bottom of the form allows for entry of repairs performed to correct the problem, the names of the parts replaced, the part numbers replaced as well as the serial numbers of the defective items. . Everything electrical still works on the truck, it just wont fire and run. If the base engine condition meets specifications, the injector s may not be functioning correctly and will require replacement. The right side of the form provides the technician with the procedures to diagnose a performance complaint examples listed below.
Smoke Black Smoke Air intake or exhaust restriction, exhaust back pressure device closing, turbocharger failure, loose injector, clogging catalytic converter, altitude very slight black smoke on hard acceleration is normal. Had the 'no start' this morning again. Check Engine Oil Level 3. If porosity is suspected, it is recommended to replace the reservoir first. A reservoir that drains back after the engine has not been operated for a long period of time can cause a hard start condition. Ambient Temperature: Glow plug on time and exhaust back pressure operation are dependent on ambient temperature. One shunt conducts the current to the glow plugs in the left cylinder head and the other shunt conducts the current for the right cylinder head.
No fuel return indicates clogged or blocked return screens or orifices which may not allow air to escape from the system and contribute to rough idle. Measure Resistance to Ground Connector Checks To Ground B- The second step is to measure the resistance of all wiring harness connectors to ground preferably the negative battery cable to determine if a short to ground condition is present. Easily choose which tune is right for your driving conditions on-the-fly with the included 8-position switch. It is only a matter of time till all the glow plugs fail. When your truck losses one glow plug it will become harder and harder to start. Conditions are described that may contribute to rough idle and the reason for performing the test is listed below. I cannot get the top off of the fuel filter off it is pretty cold here and that could be why, but I changed the fuel filter about 6 months ago and I did put it on pretty tight.
The correct torque is between 17-19 lb-ft. Single grade or 15W 40 oil is recommended for cold ambient temperatures. Intake and exhaust system, fuel delivery and filtration system, high pressure fuel system and injector operation, turbocharger and exhaust back pressure operation, oil aeration, base engine condition and electronic control system condition. Fuel Pump: Possible Fuel To Oil Leak Paths Fuel In Coolant Probable Causes Injector sleeve Upper section of sleeve to fuel galley. A milky white oil indicates possible coolant contamination and will have an ethylene glycol odor.
