No start, 1990 240DL Wagon Been Sitting 3-4 years 200 1990

Hi,
Car had no starting problems prior to sitting for 3-4 years. The battery has no charge but when given a jump the car just turns over with no start. Seems like it's not getting fuel? Added 7 gallons of new fuel in last week. AAA person says it must be the fuel pump(s). Could they be stuck or just need replacing? Or something elses? Any advice on how to proceed to get the car fired up would be greatly appreciated.
Best,
John

    I don't remember when the change was made but look to see if your car has a red wire connected to the positive battery post. If it does follow it to the 25 amp fuse holder less than 24" away. These have a tendency to corrode over time and are familiar problems. If you have one clean up the contacts.

    There is a white fuel injection relay attached to the firewall above the passenger's feet. Remove the bolster to open that area up. You should feel/hear the internals move when turning the key to the run position. This should coincide with the brief running of the fuel pumps. Sometimes tapping the relay with a screwdriver handle while trying to start the car will engage the relay. If this is successful you can usually resolder the circuit board as the solder joints have a tendency to crack over time.

    There is also a procedure to bypass the fuse and relay involving fuses 4 and 6 in the fuse box. It involves using a jumper wire to force run the pumps. It has been awhile and I am not positive but I believe The jumper is used to connect the left side of fuse 4 to the right side of fuse 6. Perhaps someone can verify this.

    With the jumper in place the pumps should run and since it ran on starting fluid it should run with the jumper in place. This would indicate a fault with the 25 amp fuse under the hood or the fuel injection relay

      Thanks! Valuable information . . . I will certainly check these things as soon as I find the key (yes, now I have misplaced THE KEY! . . . may just have to get another made).

        Check out Art's writeup about the in-tank or transferpump here (image below linked in from that site).
        It includes the jumper procedure mentioned by rstarkie.

    You might have the same problem I've been dealing with. If the car was parked with fuel you may have a tank full of varnish, like I did and posted about it quite a bit. When you turned it over it could have pumped that varnished gas all through the system, that's what the previous owner had done to my car before he sold it. Now the car I'm restoring was parked for at least ten years (I think it was closer to 15) with about 3/4 tank of fuel, so I had about the worst scenario with this. It could be your pumps but it could be anything in the fuel system up to the intake manifold--or everything, that was my problem, it all had to be either replaced or deep cleaned from the filler cap to the manifold. If its turning over check to see if it has spark and also open the oil cap to see if the cam is turning, that's a good sign that the engine has compression. Pull the fuel line off the rail, put a mason jar on the line to catch what comes out and turn the engine over, and see if anything comes out, that will tell you if your pump has any life left in it. See what the fuel looks and smells like, if its dark and smells like varnish that could be your problem. Next thing I might do is to check the injectors, mine were completely crusted and it was easier to replace them than try to clean them. A varnished fuel system is a nasty, time consuming and potentially expensive thing to clean, I really hope you don't have to deal with that.

    This is not going to be easy to answer from this side of the keyboard without some more information.

    Can you describe what the AAA person did to determine that the fuel pumps are at fault?
    Did he/she check if there is a spark?
    Can you hear the pumps run for one or two seconds when you switch on the ignition?
    Did you add the new fuel before or after the first attempt?
    What is the condition of the fuses and fuseholders?

      Hi
      Thanks for the response . .
      -The AAA person only checked the battery. Just made the observation without really checking anything out.
      -No one checked for a spark.
      -I'll have to have a listen for the pumps when I get a charged battery in it.
      -Added two gallons of new fuel for first attempt. Then five more gallons for second attempt a few weeks later (last night).
      -I'll have to have a look at the fuses/fuse box. Everything seemed okay prior to it sitting.

      John

        So basically, the AAA person was of no use.
        If a car has been standing for some time, all kinds of nasties can occur. Who rests, rusts, as they say.

        What fuel system is this car equipped with?

        I would begin with the simple things. Check if the fuses are still making good contact, a known weak spot in this car is the fusebox. Take the fuses out, look for corrosion, clean them and the holders and put them back (preferably one at a time and with the battery disconnected).

        If that didn't solve the problem, then I would check for spark. If the ignition system appears to be working, it's now more likely a fuel problem.

        Follow pdunn's procedure to check for fuel flow and fuel quality from here.

    Spray some starter fluid into the intake. If it starts then suspect the fuel pump. Gasoline can get nasty when old.

      Hi,

      It fired up briefly with the starter fluid, so I'm thinking perhaps fuel pump(s). I'm confident I can replace the in-tank one, but not so much the main as it's underneath and I don't have a way to get the car up and get under there.

      Any chance it will just be the one in the tank that's giving me the no-start problem? I guess I would find out after I replaced it but still curious . . .

      ]Thanks,
      John

        Unfortunately, that's very unlikely.
        Often the only symptoms of a failed in-tank pump are a somewhat noisier injection pump when the level in the tank drops below 1/2 or 1/3.

        Unless you're physically incapable of working under the car, replacing the pump and fuel filter are doable with the car on jackstands.

        But before doing any of this, make sure the pumps are actually getting power.

          Thanks so much. I assume I'll need a voltage meter to check for power . . . I supposed it's about time to get one.
          Yes, I'm physically capable so I'll get some jackstands and go from there.
          Really appreciate the guidance on all this.
          John

            If it's just to see if the wires to the pumps carry a voltage, then a simple test light should suffice.

            The simplest test to see if power is getting to the pumps is actually to hear them run, then you'll also know the fuel relay is working (known for failing).
            The thing about the LH-Jetronic 2.4 is that it cuts power to the pumps if the engine is not running (except for about 1-2 seconds after switching on ignition). You can force the pumps to run by using a jumper wire between two fuses, as explained here.
            Especially the main pump under the car should be audible. Maybe a bit less so if it's an original Bosch but many aftermarket replacements can be quite noisy.

              I'd just add if you do the jump and you're sitting on the rocker panel next to the fuse box with your door open and its relatively quiet, when you jump it the sound should be very obvious. Its a whirring/buzzing kind of sound from right in front of wheel where the main pump is on that tray.

            Checking the voltage is a good idea. Also, before you jump into replacing the main pump check to see if you are getting fuel at the fuel rail per pdunn. If you don’t have one already I would consider getting an additional fuel filter. Emptying the tank and starting with fresh fuel before installing a new main pump (expensive) is also recommended.
