Possible fuel problem.

#1 Post by tonyinbeds » Sun Feb 09, 2020 3:06 pm

Hi,

It's a thoroughly wet day and I went out to start the car, it fired then stopped. Lights on dash all ok and turns over but no sign of actually firing. I'm thinking possible fuse on fuel pump if water has crept in but while I'm waiting for a dry day does anyone have any similar experience or suggestions, cheapest first, something like a censor, replacing pump will probably be last.

I removed the petrol cap and replaced in case of vacuum but nothing.

Gauge reads over half and put £40 in last Wednesday and not been anywhere.

Thanks if you can help.
Cheers

Tony

You should be able to hear the pump prime

Thanks, whereabouts is the pump? Not looked yet.

It should be very audible as soon as you go to key position 2

If you crank it over & then remove a spark plug if it's wet you've got fuel coming through, if its dry you haven't.

If it's wet put the plug on a suitable earth point & get someone to crank it over, it probably won't spark which will point to an ignition fault. I'm too familiar on the D16 but I think there's some electrical bits in the Dizzy cap that can fail.

If the plugs dry there's no fuel getting through, which could be failed pump (no buzzing). If there's buzzing it would suggest a blockage of some sort possibly a collapsed/crushed pipe or even a clogged filter.

Had a complete ignition failure a few weeks ago. It was the coil, which sits in the distributor. 30 minute fix. It is more likely to be an electrical failure in the ignition circuit somewhere I think, rather than a fuel pump failure. By the way, it's Fuse 13 for the fuel pump.

Hope, for your sake, it's not the fuel pump, as this is a tank out job and a fair few hours work.

Thanks for the tips... it's not raining so about to go out and fuse fiddle.
I did download the Electrical Fault Finding Manual which has suggested the Fuel Cut off solenoid too.
Process of elimination as usual starting with easiest and cheapest.

Ok,
1) Check the fuse - OK
2) Turned ignition on and heard buzz - ok
3) cranked it over and almost went - mmm
4) Lifted plug 1 (near Dizzi) wet and smelled of petrol, also fuel smell from pot - ok
5) Laid it on the rocker cover with HT connected and tried to view through bonnet, and cranked it over but no spark. - not ok.
5) Plug gap looked wide (been 2 years) so decided to lift all of them.
6) Plug 2 was drenched in oil, I am working on theory this means the rocker cover gasket has gone - as I don't want to contemplate anything more serious but if you have a thought on this please let me know.
7) Plug 3 and 4 ok.

PLAN
a) take battery off and give good recharge.
b) check all lead LT etc for signs of wear or breakage.
c) source condensor and check inside of Dizzi cap for anything.
d) clean plugs and check gap.

Any other thoughts all welcome.
Cheers

Coil - Part number FDU1814EVA here:

https://rimmerbros.com/Item--i-GRID002302

No doubt you can find a cheaper one on e-bay.

Can't see that it would be multiple plugs failing at the same time. If engine cranks I can't see it being the battery (but it costs nothing to charge it). You would be best to check more than one of the plugs for spark by resting on engine.

Oil on plug can't be rocker gasket (unless plug was not tight). Most likely inlet valve/guide wear or seep from HG (unlikely anything worse).

Could be main lead to distributor cap, if all plugs not firing.

Otherwise, you're looking elsewhere in electrical system.

Cheers...
The battery charger readout did indicate battery was at low V and charge so may be an issue.
I'll clean and reset plug gaps first, put them back in and see what happens...
..rain stopped play for now.. :sad

I replaced my 30 year old coil with a newer 29 year old one.

Ok, just tried it with fully charged battery, and plugs cleaned and gap set (1.1mm) I found on here.
So put Plug 1 on the front panel next to an earth bolt and fired it over, on my own but it was dark so I could see a spark, not brilliant but given the connection to the earth is probably not nevertheless it was still a spark.
Put all 4 plugs in a turned it over for 3 secs twice but nothing.
Started to rain so called it a night.
More investigation into it tomorrow.
Seems odd to get a spark and fuel but not even offer...
I'll feather the throttle tomorrow when I have more time. :unsure

Good idea checking at night, that way you can see any arcing sparks.

We had a breakdown in my Sons Rover 45 Sunday, luckily it was just a dodgy main earth lead.
