Hey all,
Great forum!!! Thanks for bein here!
This is my first post and hopefully I'm ok starting a new thread for this issue... I been thru 2 weeks and huge numbers of posts regarding similar conditions, though none have led me to a resolution. :banghead:
Most of my life I've bled blue (I like my Fords) :shrug: but I came into a 1993 Safari XT AWD (VIN W)... man these things are AWESOME, minus the damn injection system! I live in MN and this van is built for this weather... can't get it stuck!
OK... to the point. Forgive my lengthiness... I'm 2 weeks without wheels and stuck.
Background:
My Safari recently died after an 800 mile trip. It began as a misfire/hesitation exiting the Interstate, progressively got worse and 10 miles later pulling into the driveway (I got lucky) it died and would not restart. Cranks, won't fire.
Figuring I had run the thing empty, I know... :naughty: , I added 5 gallons... no go. To the standard troubleshooting fuel-air-spark....
-Spark is good and hot to each plug, but I replaced cap, rotor, wires and plugs for good measure.
-Fuel... pump was priming, pressure KOEO 60+psi and 80+ with return pinched and minimal leak down. I did find relay connectors for the fuel pump & manifold valve had melted somewhat and were "gooey". Repaired the connectors, testing all wires ensuring no shorts or excessive resistance... all seemed well but the melting still concerns me. Tested PCM connections, no issues. Dropped tank... connections and internals checked out in there... cleaned the "sock" and tank, changed filter (out toward engine), traced wiring and lines looking for leaks or restrictions (none), re-did grounds... including the thermostat grounds. Pulled and tested EGR... good with minimal carbon build up. Oil pressure switch also within spec. Add 9 gallons of fresh gasoline. Bleed air out. Pressure still kosher.
Still no go...
Off comes plenum... holy oil batman! It seems I missed the PCV valve had been removed at some point and not replaced
, having the hose stuffed into the valve cover. Nothing is leaking to or from the spider. Power and pulse seem to be there at the connector, but when cranked poppets don't spray. Am I overlooking something that would cause this?
Currently... I'm am cleaning the plenum/spider as things were saturated with standing oil (hoping for a short here and will find joy after re-assembly. Intend to replace ETC sensor (near thermo housing), but current one seems to check out. Also replacing pigtail and hoses that are brittle.
Also, could be mere coincidence... during my trip i had run into a downpour and had wipers running, go to turn em off after rain and they refused to do so, all speeds worked, just would not shut off. As I went to exit interstate to check things out, they stopped. :? Some of the MANY posts i have read thru mentioned a possibility of a no start/stalling due to connection issues or switch in column, but not in detail. Any thoughts on possible relation?
The temp gauge also had been intermittently going pegged, connector seemed lose, but sensor ohmed out fine and grounding wire proves gauge working... now back on tightly.
Found THESE article I have not seen in any of the posts or forums...

http://www.asashop.org/autoinc/feb2000/techtotech.htm... could have been useful at the beginning. :violin:
Any help would be much appreciated while I have the spider exposed. :feedback:
:ty: Thanks for your time... hope to have my wheels back today as cabin fever is setting in.
