No start, no fuel 850

I have a quick question re: 1995 855T. It refuses to start, nice crank and no fuel pressure. I pulled the fuse, OK. I pulled the relay and jumped with a paper clip, no pump noise. So I am assuming the pump gave its last gasp.

The question is about the relay. With the paper clip in place, I got 12V at the pump wire. With the relay in place, nothing?? Granted, it does take a few seconds to get from the passenger seat to the back of the car and plug in the voltmeter, but zero voltage at the pump? Did the relay go south at the same time?

Anyone try a fuel pump like this one, for $20????:

    WHAT!

    Klaus, you only have a set of pin leads! This is the guy that is the highly regarded Oracle of Minnesota?

    Go to Radio Shack and pick up a new set of leads - save them for resistance and other delicate measurements.

    Cut the old leads in half and add a set of insulated male/female spade connectors.

    Now fabricate some special lead ends, with alligator clips, spade connectors or whatever you think will be handy.

    Make extension wires with spade connectors (as long as the car?)

    Add a couple of more wires with various connectors, and you will have an inexpensive kit to keep in your car to trouble shoot, or run power or ground to most devices if something fails on the road.
    ,
    Include some leads so that you can bring two females together with a fuse in the middle, so you can fuse a temporary power wire

    I have used my kit to power a brake light switch, make a horn work, and run power to the unwired 850 seat in my 544 if I need to move it.

    If you are worried about accuracy, you can zero ohms, you can check your leads against a good pair by measuring voltage across your battery, and all current in a curcuit HAS to go through your leads, like it or not.

      There is no more Radio Shack! No more little light bulbs.

      Harbor Freight has cheap multimeters with alligator clips. I could always use a spare. Yes, my bin carries male and female connectors with small spades. But my garage is still too cold!! Poor fingers...

      New pump motor comes tomorrow afternoon.

    Plug in the voltmeter and leave it somewhere you can see it from the drivers ( or passenger seat). Try the key...

    So many aftermarket parts are pure junk. I don't think 'you get what you pay for' has ever been more true.

      Cheap is cheap.

      Bought and installed a ProParts fuel pump for the daughter's 14 yr./180,000 mile S40 as a preventative maintenance measure. It was $100 vs. $340(?) for a pump from the dealer. It lasted 6 months/3,000 miles. Fortunately it failed within a 1/4 mile from home so I could drag it back to the house with the 145. Of course, it was just out of warranty.
      Purchased a factory pump after that.

        New Bosch pump 850

        The new pump is installed and all is well again.

        BUT, I really don't like clipping wires and crimping on new spade terminals when the originals looked so good.

        AND, the old fuel line was not quite as long. The new pump is shorter than the OE by a 1/2 inch or so. That makes the fuel line that much shorter. I did manage to make it work, but the clamp is just barely on the top nipple. I didn't have any spare line that fit and the auto parts store is a 6 mile walk - last time I was there, they didn't carry metric lines and all I had at home was 1/4".

        But, it works! I doubt that it will ever fall apart. No leaks!

        Now to get a spare FP relay and a new fuel filter.

      True about getting value, except when it comes to dealer prices for most parts.

      I have a sneaking suspicion that the fuel filter is almost clogged and caused the pump to over work and fail prematurely. So that will get changed out as soon as the car is running again.

      The leads on my voltmeter are pins, which work great for female couplings, but they need to be held in by hand. I guess I will recruit a helper to turn the key :)

    No voltage unless you are cranking. Normal, check while someone is cranking it over. Haven't tried that pump.

      Thanks Bob.

      The $20 pump sounds to iffy. I am going to get a Bosch insert so I don't have to worry about it all of the time.
