awsome vid helped me out

Thanks very much!

Hey, I'm really glad it worked out for you! Here's another tip you might want to do just as preventative maintenance. I've come across 2 Ducati in the last 6 months with issues where the engine will randomly die. These are really hard to diagnose because you can't reliably duplicate the problem. Sometimes they start right back up again and run fine for days. Apparently it's a super common issue. There's a fuel pump relay that's very common problem. Just look up Omron G8HL-H71 on Amazon. They're $9 for two relays. Perfect because the bike has 2 relays this size. Replace them both. This fixed the problem on both bikes. One of them had been randomly dying for years and and finally completely died. So, I was able to catch the relay failure.

Sam, YOU'RE great!

Thanks for the encouragement, Shane.

Thank you, Otto.

Thank you for the encouragement, Tomo.

YOU'RE amazing!

Yeah, they're alright.

Thanks for the comment, John!

I hope you get it fixed. Thanks for commenting.

@@redneckoriental Thanks to your video I have already confirmed that the pump is good by applying 12V to it..... AND, I confirmed I am not getting 12V to the pump, but I am getting an immobilizer error..... the light flashes once (indicating the immobilizer and ECU have lost their serial connection), then the light goes out, and comes back on and stays on, to indicated a problem. IMO the Immobilizer system on these Ducatis is needlessly complicate. If you know a good resource, I am all ears. Thanks again for your video.

@@RWayne-nu2fi My brother just had to disable the immobilizer on is 1198. He said first, open up the trim around the ignition lock cylinder and make sure immobilizer antenna ring isn't broken, wires disconnected or wires broken. If you want to permanently disable the immobilizer, you can buy a cable to access the ECU (through eBay, $65). Then, download the software (free) and the binary files. He can get the binary files for you. Please let me know what year and model your monster is. Also, there is a sticker on the ECU with numbers. Please give me all the numbers off those stickers so he can provide the correct files.

@@redneckoriental Thank you! Much appreciated. I have a 2002 S4 Monster. Like I mentioned, I am getting one flash from the IMMO light, indicating that the IMMO and ECU have lost their serial connection. According to a couple of Ducati dealers/service people, that is often (always?) a simple "wiring" problem. I am told that you can fix this issue one of two ways, 1) find the wiring issue and fix it, or 2) re-flash the ECU and defeat the Immobilizer function. (In an ideal world, I like option #2.) Give me some time to chase wires and if that fails I will provide you with the ECU numbers, etc. My ECU has an "UltiMap" label on it..... they were a Ducati tuning/reprogramming group out of Australia.... they are out of business now evidently, but that information might be meaningful to your brother. I have checked the antenna and its wires, all good there. If he's in the habit of doing this, I might just $end him the ECU!! Thanks again, I appreciate your help!

Here's someone selling the fuel pump in eB www.ebay.com/itm/173883408497. Here's the Wix fuel filter: www.amazon.com/gp/product/B000C9WJBM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1. Here's the fuel hose (get 2 if you plan to replace both in-tank hoses): www.amazon.com/gp/product/B001R5XSGU/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1.

I put the part numbers in the description of the video. Please diagnose it before you throw money at it.

I've figured it out! It's a sleeve for the pump nozzle when you're gassing up. You should've connected it to the bottom of tank cap. Part 802.1.005.1A (they call it just "hose") parts.powermotorcyclesusa.com/p/Ducati__/Hose/42747804/802.1.005.1A.html

@@IanSampaio Great find! I'll have to reach in there and grab it.

Btw I just liked and subscribed! Thanks

It was a short explanation in the video. That strainer sock tends to deteriorate and fall apart, as this one did. The system already has a fuel filter to protect the injectors. The sock just keeps large particles greater than the size of sand from entering the pump. I've never found rocks at the bottom of a motorcycle fuel tank. So, I don't think the sock is necessary.

I just updated the video description with links to where you can buy the pump, filter and hoses.

@@redneckorientalcan you please include the link for the parts. Pomp and filter please. I am need need

@@saululloa3123 Pump Bosch 43040041A . Fuel filter Wix 33032. In-tank hose, Gates 27093 (you will need 2 of them if replacing all the hoses in-tank.

@@redneckoriental yes ser. Thaks

Your problem is is harder to pinpoint because it's intermittent. Normally, you'd check for power to the fuel pump when it's supposed to be be on, like during priming. If you have power, but the pump doesn't run, then you have a pump problem. If you have no power when there's supposed to be power, the problem is somewhere upstream. A cheap thing to eliminate would be the fuel pump relay. This is a high failure item. There are 2 relays. I don't remember if they both affect the fuel pump, but I replace them both anyway because they're cheap. You can find them on Amazon for $9. Search for "g8hl-h71". Stick to a good brand, like Omron or Bosch. There is a way to bypass the relay with a jumper wire if you want to do this before buying the relays. If you look at the relay, there are 4 pins. Google the "g8hl-h71", go to images and look at a diagram of this relay. Pins 3 and 5 are the ones that need to connect when the relay is on. Remove the relays from the bike On the sockets for the relays, install a jumper wire to connect 3 and 5. Do this for both relays.

@@redneckoriental so all the relays and fuses look good and in great shape, nothing corroded or burn and everything is clean. I replaced the two relays since they’re were cheap and bike still runs fine but sometimes I can hear the pump inside the tank while cap is open it’s kind of sputters and clicks when priming. I got a new pump and fuel filter too. Now my question is how do you take off the old pump? I can see it at the bottom of the tank but don’t want to pull or twist anything and damage something.

@@Leona31007 It does sound like your fuel pump is going bad then. If you have a steel tank, like the one in the video, just pull on the pump and it will come out. It just slides into a rubber sleeve. There are no fasteners holding it on.

First, find out if it's lack of spark or fuel that's causing the hard start. Remove the air filter. Spray carb cleaner or brake cleaner into the intake for 2 or 3 seconds and crank the engine. If it wants to start right away instead of the usual hard start, you know you have a fuel problem. If it's a fuel problem, you may want to start by replacing the 2 relays. They're cheap. Look up "GH8L-H71 Relay" on Amazon. If these look like your relays, replace them. Otherwise, do like in the video and check for power to the fuel pump while cranking. Where are you located?

@@redneckoriental Western Montana! What kind of spark tester do you use?

@@tychormthorp Cheapie one with a light bulb inside. You can get one from Harbor Freight tools if you have one nearby. Otherwise I think mkst auto parts stores sell them.

@@moocow2529 nice, I'll pick one up and check it

@@redneckoriental The bike is actually capable of starting, but it's a hard start that will stall and die after 3-5 seconds, even with the fast idle on. Both of the headers were warm after attempting to start a couple times, and I was getting a burning/fuel smell from the right pipe for some reason (even though they meet in the middle before splitting off to each tailpipe?). If I give it any throttle while cranked it will almost immediately stall. I recall the previous owner mentioned something about fuel pump issues and finding pieces of the sock in the tank, and I suspect he may have never properly cleaned it out. Last year I put it in a heated garage and dumped a bottle of injector cleaner / stabilizer into the tank, and there's ethanol added to the 91 up here so I suspect the fuel is muck with bits of broken sock and gunk by now. I pulled the plugs and they were black as night (not blued, everything from the gasket up to the electrode was thoroughly fouled). Would you mind if I sent you pics / video? Might make things less abstract. I started in on it this week! So far I've; 1) Verified spark with a bulb tester, looks consistent. ______________________________________________________________________________________________________________________________________________________________________ 2) Verified battery is making ~12v and appears to be in spec when checked with a load tester. That being said when I turn my ignition on, a multimeter indicates the battery is producing 10v, and when I attempt to crank it the voltage drops to ~ 7-8v - I had the battery tested at two different shops in town and the folks there said it seems perfectly fine but could we be missing something? ______________________________________________________________________________________________________________________________________________________________________ 3) Replaced the fouled plugs, the bike seems more willing to start and idle is slightly more healthy but still has issues w/ idle rpm slowly dropping then stalling. ______________________________________________________________________________________________________________________________________________________________________ 4) I have checked the fuses, ordered the relays ______________________________________________________________________________________________________________________________________________________________________ I will drain the tank and check the tank / pump for debris while I do - like I mentioned above I suspect the fuel in the bike is sludge and am curious to see if fresh starts it. I'll comment again after I've changed fuel/verified pump, filter/installed new relays. Will also spray some carb cleaner into the intake to see if it starts more easily. Thanks so much for the helpful advice so far, I can't wait to get back on the road!
