fuel problems dutton

[Alan A1]

Help, Just bought a Pheaton S1, lovely car but i'm having a problem, after i have been driving for about fifteen mins the car seems to start to starve of fuel, it missfires shudders and evenually stops compleatly i've plenty of fuel and i've just changed the filter in case it was glogged up but the problem persists. can anyone help, please keep the jargon and novice/idiot level please.

Sounds a little like the filler cap or tank isn't vented. When it does it, get out and open the filler cap. Does it release a big suction???

[Alan A1]

Thanks Ferg i'll check that out later tonight when i use the Pheaton to drop my boy off at his school prom he reckons it's cooler than any limo.

[Ferg]

I was approached by a girl at a car show and asked if I'd drive her to her Prom in the Libra.
That's tomorrow night, so I'm going to give it a good wash tonight!
Her parents are paying me in beer!

[Alan A1]

Just dropped him off, rollers, limos, hummers, and my boy said the phaeton was the best and better still as its ours, still the same problem though, checked thefiller cap no suction, must be something else any sugestions anyone?

It could quite simply be a matter of the fuel pump not delivering enough fuel for the carbs... I've known similar symptoms when the fuel supply can't quite keep up, so whilst the car starts and runs just fine, the fuel level in the float chambers is gradually reducing to the point where after 10-15 minutes running the mixture leans out and the engine stops.

What carbs do you have, what state of tune is the engine in,what fuel pump set-up (mechanical or electric) and do you have a fuel pressure regulator fitted?

[jonnoak]

Also its worth checking electrical system (something getting hot and breaking down) so check leads, rotor arm etc
Good Luck

[Alan A1]

Thanks guys, looking into your suggestions i'll get back to you with the results

Fit an in-line filter near the carb, when it stutters to a halt check to see if it has fuel in it. Old cars have tanks full of all manner of crap so worthwhile anyway.
Could also be coil or condensor TBH.

I'm with stupid

I've had twin 40's on the Quantum and a failing Facet gave exactly the results you're describing

+1 As well. Fitting a "proper" clear in line fuel filter AFTER the pressure regulator will help you split the system for diagnostic purposes. FYI my original pump eventually failed (with those same symptoms) due to swarf, presumably from tank, and no I hadn't worked on it!!

My old dutton sierra suffered similar problems with the crossflow engine. It was sucking a lump of tank liner into the end of the pipe, ended up with a new tank from beevers auto panels.
If you are running a twin choke webber there is also a little filter in the pointed end of the carb where the fuel pipe goes in, inside the chamber under the big brass nut.

Other possible items to break down could be the condenser or coil.

Whats the setup? pinto or crossflow? single choke carb, twinchoke carb or multiple carbs? manual or electrical fuel pump?

Have you tried asking the previous owner if he has any ideas?

I had a similar problem on my Westfield and we checked everything. In the end there was a rubber pipe taking fuel from the tank into the metal pipe running the length of the car, this rubber tube had bent in half so couldn't suck enough fuel into the carbs, it was litterally a couple of quid and an inch of pipe that sorted the problem.

Mate of mine had a crack in the rotor arm of the dizzy, only stated misfiring when it had warmed up. Also try a new coil if all else fails.

[Alan A1]

Just fitted a new coil, taking it for a spin later tonight, i'll let you know how it goes once again thanks for the input.

[Rebuilda]

BUMPED

How did you get on with the new coil, did it solve the problem?

[Alan A1]

sucess, the new coil solved the prob, it runs like a dream i'm having new pedals made to give me more leg room and then i'm looking forward to many days happy driving that is of course once i've figured out how to reattach the gear stick that came out in my hand after taking the car out last night, it appears a pin has snapped. back to the drawing board.

[Rebuilda]

What gearbox is it Alan.
I have a box full of xflow based gearsticks...

Normally the thread goes or the tabs break allowing the stick to undo itself..

[Ferg]

Yeah, that plastic thread is just excellent....

[Alan A1]

Hi rebuilda according to the paperwork i have the gearbox is a mk3 cortina 1600E but i think it must be the mk2 as i don't think they made a 1600E in the MK3 its a 4 speed 'bullit' box can you or anyone else help
