Question about 2001 Nissan Pathfinder
Posted by Anonymous on
I would say something cut into the wiring harness. Maybe it is resting on a hot pipe, but that is a lot of circuits. It has been running rich, which may have caused the converters to fail. Do not replace them until the problem is solved and only if tbe 420 and 430 codes come back. Check the ecm connector and the unit itself for damage. The ecu looks like it's on the center of the firewall, but I'm not sure if it's inside the cabin or engine compartment.

SOURCE: long crank time before starts
Thoroughly clean interior of throttle body especially area where butterfly flap seats and all drillings, use aerosol carb cleaner, check air filter and spark plugs (platinum type only!). Then set idle with a consult unit or similar, engine management must be in service mode to set idle properly.
Also test coolant temp sensor it may be open circuit. If you don't know how to do this ask me.
Forget about earth if starter turns engine over at normal speed.

Do you have a check engine light with this?
What can happen is a code has caused the engine to protect itself. For example in a low coolant situation when the engine heats up too much, the engine can Knock causing an Engine Knock fault.
If that occurs you will recieve a fault for each of these items. Fill the engine with coolant. Then reseting the code will let your engine accelerate normally.

Primary ignition fault. Reasons: Bad distributor cap (most likely) or ignition control module/ignition coil.
Hope that helps

It sounds like the rings are washed out for some reason. any chance you filled up at a gas station with water in there gas ? if it was me I would do a compression test and see if it is low , and it sounds like it might be then leave the plugs out and put oil in each cly turn engine over a few times and let sit over night or at least serveral hours , this will free the rings up , fuel and miss fires will wash the rings out and running will get you white smoke , after oil has set in cyl now you have to clean it out if you have qa air compressor you can shoot air into each keeping a rag over so you dont make a mess, and you can keeping one end in hand send a rag down to soak it up, you will most likely have to pull the plugs out and clean them with break clean a few times till the engine will stay running once it stays running it will smoke until the oil is gone but the compression should be back to normal and cleared up it might smoke for over an hour once you get it running you can hold throttle to 2000 rpm as well this helps a bunch. but find out where compression should be and check it . I think some how either the missfire or bad gas. did you replace any coils or coil pack ? is the miss fire gone?
