HI All
88 Ranger, 2.9L V6, 5speed, 4x4, ext cab,
No power accessories, no air, no cruise.
External fuel pressure gauge shows NO pressure at all on the fuel rail.
Using Tpins I probed the wires on the inertia switch and there's only 7.5V going through the switch.
Is 7.5V normal?
My Chiltons of course does not show that detail so I'm not sure if that's a symptom to add to the mix or if 7.5V is normal.
We went 4 wheeling over the weekend and after 3-4 hours of rough trails and steep inclines the engine just stopped as if it ran out of gas.
Tank is 3/4 full.
My first thought is being 20 years old and this is it's first time out on rough bumpy steep trails we mixed up all the dirt and crap in the tank and either clogged up the new filter (about 1000 miles old is all) or we killed one of the fuel pumps.
Went back the next day to tow it home and the battery would not turn over the truck. Had the truck 6 or 8 months and this is the first time the battery ever had an issue. I put a charger on it and I am charging the battery.
The 7.5V is with the charged battery and the charger still on the battery.
Turning the key I hear a relay click somewhere near the airfilter box.
But I do not hear the front fuel pump, I don't think I have ever noticed any sound coming from the front pump but I have never listened for that either.
Symptoms so far.
1) Lots of rough and steep trails bounced the truck around a lot.
2) No fuel pressure.
3) Battery suddenly or coincidentally lost or loosing charge.
4) 7.5V going in and out of the inertia switch.
5) No sounds from the front fuel pump.
6) clicking sounds from the near the airbox.
No flashing engine lights or anything.
I have not done any other diag's yet, Hope to get to that this weekend.
I do have a obd1 that I will use as part of the diag's.
Any thoughts before I start taking stuff apart and diagnosing it?
Thanks
Bill
