<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I spoke too soon about the "mystery fix".of car cutting out after a second or two of good running.<br> After doing that fuel system wire (#19) grounding on the manifold, to run pump longer, the car made a couple mile round trip for plumbing stuff, then the next day (temps still in the 20s), it started easily and ran, sitting there, for a good ten minutes.<br> But an hour later, getting set to go out, it ran for about 3 minutes (warming it up a little) then cut out again. Started it again...it ran for a minute. After that, just the one or two seconds.<br> So...as per Bob's note below, it looks like the pump is "getting tired". So, I'll soak a couple of dry-stored spares in diesel an get to the job of HOPING one of them works.<br> But, before doing that, is there any way to assure that it's a pump problem?...not one of
the switches or something? (I have a bunch of relay switches.) Clean filter was put in just a month or two ago.<br> If I did that wire grounding trick a few times, would that FIX the problem, or just delay the inevitable?<br> A pump change job, on the street, without a good jack even, is not fun...especially with hands already half ruined by heating oil work in the house.<br><br>Subject: Re: [T3] Mystery fix<br>Message-ID: <<a href="http://us.mc1260.mail.yahoo.com/mc/compose?to=422a3.31bd4a9f.3e346fb6@aol.com">422a3.31bd4a9f.3e346fb6@aol.com</a>><br>Content-Type: text/plain; charset="us-ascii"<br><br>In a message dated 1/25/2013 5:47:28 P.M.

That was fixed just by adjusting points a little <br>and giving all the wires and hoses a nudge and a
check. Let it run for <br>about five minutes to warm it up...it being about 20 degrees. Took it for <br>a successful spin around the block.<br><br>But, a half hour later, car wouldn't start. That is...it "ran" for just <br>seconds after starting, then died. Yes, two clicks heard for the fuel <br>system, no gas smells, etc. If I primed several times, it ran for a couple of <br>second longer. Checked pump elec plug. It was ok. But still same <br>symptom...start then instantly die.<br><br>For no reason except to experiment, I un-coupled the Fuel System wires in <br>the engine compartment, grounded one against manifold---which worked to run <br>the pump. (Is that what it does?) <br>THEN I tried to start it...and it worked. Went for a test drive around the <br>blocks. Fine. Let it sit and tried again. No
problem.<br><br>Thing is....Why? Was it just a matter of a bad, dirty connection? Even <br>though it's in its plastic sleeve, and snug with the other wire <br>connection...was that it? Or did grounding it like that coax some component back to <br>life? If so, which component? And, ;if so, is this an omen that the component <br>is on the way out? The fuel pump maybe?<br><br>IF it's the fuel pump, should I plan ahead by putting a couple of my <br>spares in a bucket of gasoline now to get one ready for Show Time?<br> <br> <br>It sounds like your fuel pump is getting tired (it could be the weather <br>too, as I don't work too well in the cold ;-) ). What's happening is that the <br>2 seconds of pump prime aren't enough time, which is why Jim sells a "pump <br>prime kit". The alternative, is to cycle the key until the pump stops, then <br> repeat this a couple of times until
the fuel rail is completely filled <br>again. What you did by "grounding out that wire" (#19) and letting the pump <br>run, is the same thing that Jim's kit does (run the pump a little longer to <br>prime the fuel rail before starting). <br>I think it wouldn't hurt to "store a good pump" in diesel fuel (they don't <br>like being stored dry anyway), until you actually need it, but warmer <br>weather maybe all you need. <br><br>Bob 65 Notch S w/Sunroof and IRS aka Krusty<br>64 T-34 Ghia aka Wolfie<br>71 Square-vert under construction<br><br></td></tr></table>
