I am new to the FTE forums but have heard good things so here goes:

So I replaced the HFCM (which was a pain in itself...) because the dealer will not warranty my injectors with a bad pump. First turn of the key and the upper bowl does not fill. Check the inertia switch, reset, still not working... Pull the wire to the pump and find there is only 4.6V with <ACRONYM title="Key ON Engine OFF">KOEO</ACRONYM>. Voltage at inertia switch was 11.8. Also found a P0232 which would point to the relay.

As we know, the relay is part of the central fuse box and costs about $350 (non-returnable). Is there any way to check the relay and be absolutely sure ? Also, is the relay in line before the inertia switch or after ?

Any other ideas ? I checked all the fuses and I'm not aware of any other relays. The truck is taking up space at a friends garage right now and if I have to rent another Hyundai I'm going to lose it...

2005 Excursion 6.0 184k miles. In Harford County, Maryland...will buy any of you local guys lunch with a good scanner and some know how

Will be tackling a "bad throttle plate" and another <ACRONYM title="Exhaust Gas Recirculation">EGR</ACRONYM> valve (this will be 5 in a year) after this... Thanks for your help guys.

 

Do you use any additives (cetane boost) with your fuel?
I use dieselKleen (gray bottle) in each tank.

 

I do not use any additives, maybe I should start. This problem however seems to be electrical...not sure if it is the relay or something else -- I just cannot swing the dealer fees right now.

 

iirc the relay is non-servicalble and part of the fuse block. you need to get an wiring diagram and start checking connectors for voltage loss.
