so my truck took a dive on me.

she'll turn over but not start.
i put a new walbro fuel pump and fuel system relay and still got nothing .

ideas ??
wheres the fuel filter on this thing, is it replaceable ?

 

hmm Im a newbie, from what ive been learning, here's a thing to check maybe,,,, Are you getting pressure on the fuel lines? If so, might be your ignition coil?

 

fuel filter is in the tank, part of the pump assy.
check IOD fuse, check for fuel pressure at the rail (the little valve thing)
any spark at the spark plugs ?

 

i poured some gas in the tb and fired right up... i know the filter can come off, anyone ever replace it ?



IOD Fuse?

 

There you go. Engines need three things. AIR. FUEL, SPARK. You know that fuel is the problem so just walk back from the injectors to the tank.

Make sure your fuel pump is getting electricy, check your injectors if the are getting fuel. Be careful take your time DONT SMOKE.

IOD = ignition off draw. i didn't know what it stood for and had to look it up.



All vehicles are equipped with an Ignition-Off Draw (IOD) fuse that is disconnected within the Power Distribution Center (PDC - Fuse #18, 20amp) when the vehicle is shipped from the factory. Dealer personnel are to reconnect the IOD fuse in the PDC as part of the preparation procedures performed just prior to new vehicle delivery.

The term ignition-off draw identifies a normal condition where power is being drained from the battery with the ignition switch in the Off position. The IOD fuse feeds the memory and sleep mode functions for some of the electronic modules in the vehicle as well as various other accessories that require battery current when the ignition switch is in the Off position, including the clock. The only reason the IOD fuse is disconnected is to reduce the normal IOD of the vehicle electrical system during new vehicle transportation and pre-delivery storage to reduce battery depletion, while still allowing vehicle operation so that the vehicle can be loaded, unloaded and moved as needed by both vehicle transportation company and dealer personnel.

The IOD fuse can be used by the vehicle owner as a convenient means of reducing battery depletion when a vehicle is to be stored for periods not to exceed about thirty days. However, it must be remembered that disconnecting the IOD fuse will not eliminate IOD, but only reduce this normal condition. If a vehicle will be stored for more than about thirty days, the battery negative cable should be disconnected to eliminate normal IOD; and, the battery should be tested and recharged at regular intervals during the vehicle storage period to prevent the battery from becoming discharged or damaged.

 

i checked that fuse and its good.

also found a replacement fuel filter.
