fuel pump?? relay?? bad gas??

is all maintenance up to schedule in regard to filters and such??

how much of a diy'er are you?? tools??

i'd start with a fuel delivery diagnosis, check power to the pump, fuel pressure and volume.


good luck.

I was thinking relay as i have changed one when i first had the car.

As for tools and such i have pretty much what i need i race classic sidecar outfits and build my own motors so am a fair DIYer. just thought i would ask on here in case it was a common fault which would save some time and money changing un necessary parts.

Servicing is up to date.

well welcome to the 'fest!! :thumbup:

as with any diagnosis, i always stress checking the basics, like proper battery capacity and state, as well as things like filters and such.

symptoms sound like fuel related, so as i mentioned, this is where i would start first. depending upon what you find will determine the next move.

pics of said racing mobiles are a prerequisite, though. new rule as of three posts ago, sorry...:p

It could be fuel or spark really. Sounds like its catching fuel sporadically.. Could be a busted coil pack maybe, or like I stated earlier just a wet dme/ecu.. Any codes showing up?

Sidecar riders have tremenous skills and testes the size of basketballs. They do WAY more than ride and pray. If you've never seen a sidecar race, search YouTube and be amazed.

Edit: notice the bike going sideways in the grass in the background of dj's picture! :yikes:

Well this morning i hooked some jump cables from my wife's car so i could spin it over without the worry of flattening the battery, and reluctantly she burst into life! and ran as smooth as ever. I ran the motor for about an hour. no problem. Let it cool and it started first time. I will try it in the morning when covered in frost and see what happens then. Maybe just a gremlin then :mad:.


Thanks for all the help
