E 250 no fuel. Owners manual states the inertia switch is located above the brake pedal on a bracket---I can't find it. All I have read tells me to reset the inertia switch before looking at the fuel pump. Some places state my van doesn't have an inertia switch. Some places tell me its located somewhere else. Does anyone have a clue where this switch might be????

 

Welcome to the site..

Fuel shut off is done by a signal (event signal-impact) provided by the Restraint Control Module. The RCM and Fuel Pump ControlDriver module signal is monitored by the PCM, on moderate to severe impact, PCM disables the FP.

The reset is done through normal key cycles from Off to On.

 

Thank you Hayapower. I was afraid of that. Tried several times to start. It runs off either so it has to be a fuel problem. I suppose my next step is to drop the fuel tank and look into the fuel pump. And I just filled up before this thing went south.

 

Already found 2 fuses, according to my owners manual, for the fuel pump. Both are good. I cannot find any information about the fuel pump relay block----if it even has one.

 

If no pump run, check fuse #43 20amp in the Battery Junction Box, as well as #54 10amp in the BJB (although 54 would affect PCM) 'OR' a quick test for voltage passing through 54 and into the Fuel Pump Diode in the BJB.

If fuses test ok, both sides, next step would be to check for an active 'output' voltage at either the harness bulk head connector (+ access) BJB connector, the Fuel Pump Driver Module connector, or the Fuel Pump Module connector itself and would prove out power distribution in steps checking first that both fuses prove good prior to any probe check points.. Could be a pump, relay, but power distribution needs to be checked.

Checking for an 'output' voltage from 'Fuel Pump Relay would prove out a good/active FP Relay and overload protections.

 

What engine?
Anti Theft?

 

The fuses are good. The diode works correctly. Have 12 volts coming into the pump relay (box #5). I have no idea where to look after the battery junction box except the plug to the fuel pump-----above the fuel tank. I have no wiring diagram. Thank you very much. If you happen to think of anything or anywhere I could test a circuit without dropping the tank, I would be most pleased.

 

It's 09,, correct?
FP relay S/B in the BJB..

Engine is 5.4?
Confirm the engine and year, 'NO PATS, correct?

I can send you some connector views for some pin out test points prior to any tank drop..

 

2009 E250 motor 4.6 gas group 9FMXT04.65HA Not sure what a PAT is. As far as I know it's just a standard van. Close to 100,000 miles.

 

PATS is 'passive anti theft'. Uses chipped/encoded ignition keys. Also if equipped, has panel mounted red/flash security light.

If PATS, engine cranking, fuel injection can be disabled. One, or both, either functions can be disrupted
