Not sure exactly where to post this question as it relates of an '84 Ranger with a 2.8l V6. Similar enough to the 2.9 so thought I would throw this question to the the forum most familiar with these engines.
My son's Ranger has sat for about 6 months and we are just getting it on the road for him now that it has hit the magic 30 year old mark and can be permanently registered as a 'classic' vehicle. After we parked it for the rest of last year, we have gone through and done some needed maintenance on items that though functioning, were starting to show signs of wear or needed refreshing. New starter, new starter relay (ran into some problems here that are documented on the General Technical and Electrical sub forum, now solved), fresh belts/hoses/vacuum lines, cleaned up electrical connectors and straightened out the wiring looms, fresh plugs/wires/distributor components, and a cleaned and rebuilt carburetor. Each component refreshed followed up with confirmation that the truck ran when completed whenever needed.
Now that I've listed the things we have done I will pose my question:
Just before parking it for the latter part of the summer/fall, my son put in a new (mechanical) fuel pump. Worked fine, he drove it for almost a month with no issues. Now that it has passed the magic age of 30, he is ready to re-license it. It turns over great but we are not getting any fuel to the carb from the fuel pump. New filter installed on front of carb during rebuild and works properly. Trickle gas into carb from bottle and truck runs fine. Removed line from fuel pump and ran a hose into a bottle to measure fuel flow and nothing comes from the pump. Removed fuel line from output side of pump and there is not any pressure coming from the pump.
Is it possible the diaphragm inside the pump has dried up and is no longer forming a sufficient vacuum to pull gas from the tank? Any other thoughts or words of advise are appreciated. He REALLY wants to get this thing on the road again and I'm anxious to have my 'spare' rig back home. ---rick
