An the answer was bad fuel lines on the pump and a glob a foreign material in the filter.. Replaced all the lines and the filter. Put in some fresh race gas and Boom back to life. I did manage to cut the pump assembly gasket to the tank and had to use my emergency spare... I hope it holds as it is a few years old... Thanks all the house smell like race gas :-) Cheers, Eric -----Original Message----- Sent: Monday, March 02, 2020 0:02 To: Ducdude Subject: RE: 748 just will not start A friend had a similar problem several years ago and the fuel line inside the tank coming off the fuel filter feeding fuel to the injectors/throttle bodies had cracked and come off...so no fuel was getting to the engine... Given your attempt with starter fluid...that may not be the issue...do you smell fuel?? -----Original Message----- From: Ducdude <ducdude@verizon.net> Sent: Sunday, March 1, 2020 5:41 PM To: ducati@ducati.net Subject: 748 just will not start Greeting all, I have had a 97 748 since 1998 and while she has not been trouble free over the last 40K miles she does always start..But not today..She did run back in November when I did the oil and filter. The battery is good and she does prime when I it click it to start. I changed the relays under the seat any way As I had them and they have failed in the past. I also put in fresh plugs just in case. The main and starter fuses are good but WTH I changed them any way. Fuel lines are tight and secure under the tank and the battery connections are clean and tight. I though I would ask for ideas of things to check as the only other thing I can think of is the hall effect sensor spacing..I have not check that yet though.. Any other ideas? The bike cranks but will not pop or bang even with ether starter fluid witch leave me to think it may be an ignition issue. Many thanks for your input.. Eric
