Pete in PA Posted January 14, 2005 Share Posted January 14, 2005 weird. :???: Don't you hate when they do that? You'd rather find the problem and fix it. Fuel line ice?? Water in gas? Quote Link to comment Share on other sites More sharing options...
Guest rockmeupto125 Posted January 14, 2005 Share Posted January 14, 2005 You know how when people are just exhausted, you can't wake them up, yet there's really nothing wrong with them? I dunno, maybe hauling two bikes, two folks, and two sets of gear 1000+ miles each way tuckered the old girl out a bit...... Quote Link to comment Share on other sites More sharing options...
N1K Posted January 14, 2005 Share Posted January 14, 2005 Maybe a little condensation somewhere... somehow.... eventually dried up??? (oops... I'm in the garage again.. can someone point me back to the bar?) Quote Link to comment Share on other sites More sharing options...
bartonmd Posted January 14, 2005 Share Posted January 14, 2005 I still vote fuel pump... sometimes they'll do that when they're about ready to go... not run at all, then start running again for no reason. Been there, seen that. Mike Quote Link to comment Share on other sites More sharing options...

blackhawkxx Posted January 15, 2005 Share Posted January 15, 2005 Joe, just for the heck of it, I would put a new distributor cap and rotor on it. I had the same thing happen on my wifes car. I didn't find it for a while. When it happened the second time, I put a new cap on it and it never happened again and that's been about two years now.

Guest rockmeupto125 Posted January 15, 2005 Share Posted January 15, 2005 Put new cap, rotor, plugs and wires in before I took the van to SEXXT last year......so that's about 4500 miles ago. Quote Link to comment Share on other sites More sharing options...
demon Posted January 15, 2005 Share Posted January 15, 2005 He had a good spark, so the ignition system is OK. I'm still thinkin Fuel System. It wouldn't be the inertia switch, they don't reset themselves. It would probably be a bad relay or booster pump. I've seen the switch that switches the front and rear tanks go bad before and it causes the pumps in the tanks not to work. I have dealt with fuel injection problems for years. I used to be a technician in a dealership and just about seen it all. Quote Link to comment Share on other sites More sharing options...
Guest rockmeupto125 Posted January 15, 2005 Share Posted January 15, 2005 Well........I've not had a problem yet with the switch....but its increasingly frequent that the gauge not work on one tank or the other (needle just falls to the lower "empy" stop). Are they on the same circuit, or might that play a part in it? Thanks, Donnie. Oh...one other thing.....which seems it would be a problem with the valve, not the switch. Gas from one tank will flow into the other on a relatively regular basis. I may use one tank until its 3/4 gone, and then switch to the other only to find that its only half full. Then, if I switch back after an hour or so, there's more gas in the first tank than when I left it. There's no leak...and the gauges are reflecting a fairly accurate condition when they work, because I get the same relative mileage from a fill, and run out of gas when I observe the gauge dropping steadily to empty (rather than just switching to it and having the guage simply fall to the lower stop).

demon Posted January 15, 2005 Share Posted January 15, 2005 The switch for the front and rear tanks controls the pumps, the valve, and the fuel level sending units in both tanks. If you have a problem with the switch, the pumps might not turn on, the fuel gauge don't work right or the valve won't function properly. That switch may be your problem.

Guest rockmeupto125 Posted January 15, 2005 Share Posted January 15, 2005 The switch itself feels tight and appropriate. Is there anyplace else that might be a problem? Can the switch be disassembled? And if not, it is at basic DPST unit? Quote Link to comment Share on other sites More sharing options...
blackhawkxx Posted January 15, 2005 Share Posted January 15, 2005 Gas from one tank will flow into the other on a relatively regular basis. My F-250 had a recall on a valve that would go bad and do that. Mine never did but I had the recall work done. The recall said that if you had two full tanks and it did that, it could push the fuel out the filler cap. :shock: Quote Link to comment Share on other sites More sharing options...
demon Posted January 15, 2005 Share Posted January 15, 2005 been a while since I worked on dual tank fords, but if i recall it's a basic dpst unit. Once the switch is tripped in one direction it kills the power in the other therefore killing the relays that work the pumps and sending units in the tanks. You might be able to disassemble it and prod around inside it, but any dpst unit should work. Pop the dash surround off and take a look at it in your spare time. You might be able to replace it with a non-ford double pole switch at a fraction of the cost. Quote Link to comment Share on other sites More sharing options...
Guest rockmeupto125 Posted January 15, 2005 Share Posted January 15, 2005 The recall said that if you had two full tanks and it did that, it could push the fuel out the filler cap. Yes, this has happened before. I never fill the tanks now unless I'm taking a trip and will be burning off fuel. Quote Link to comment Share on other sites More sharing options...
demon Posted January 15, 2005 Share Posted January 15, 2005 That valve may be your culpret. If it allows fuel to go into the other tank, you might not be getting the right amount of fuel pressure to the injectors or none at all if the valve has the fuel going from one tank to the other instead of to the engine.

Northman Posted January 15, 2005 Share Posted January 15, 2005 If neither tank works, and it's a fueling problem, try the switching valve. Bypass it if necessary, or check that the suspect fuel pump(s) are getting power. Damn, I love being right :wink: Quote Link to comment Share on other sites More sharing options...
