Rough starting cologne 2.8
Discussion
Hello all,
Car has been running pretty well for the last year or so, but recently it's had a twofold issue.
1. When starting after sitting it's taking longer to bite than normal: 2-3ish seconds so nothing terrible but still noticeably longer.
2. When starting 2-3 hours after a drive, it's 'half' catching on key turn, so it turns over but roughly for a few seconds until it settles in to normal idling. Possibly not all cylinders firing? If you give it gas it will rev, but sounds a bit weird.
When hot it starts fine, and in normal driving there have been no problems, only that it possibly sounds a bit raspier than normal (but could be my imagination).
Changed the pump, accumulator, high pressure hoses, spark plugs and coil recently.
Next step for me is to try some injector cleaner, then test the injectors to see if they are all fine if that doesn't clear it up.
Then i'll check out the air pressure plate in the metering head.
Any other thoughts?

Hi Penny,

No, it's not you who's dense - I may be very dense here,
Try asking on the S Series Forum, S1 had the 2.8 and there are a couple of knowledgeable guys on there.
(or there used to be, PH is a bit dead these days)

Injectors bursting properly?
Hi, good questions!
From Cold it starts ok but rarely on the button. Normally needs a few seconds of turning over but there is some variance.
After 2 mins it starts much better, generally on the button.
After two hours after driving, that's when the issues I mentioned above occurs. It catches but sort of a 'half catch' where it's not really idling properly. After a few seconds, it returns to normal idle. Note this does not always seem to happen, but has happened a few times recently but never before.

Hi Penny,
Thanks for the suggestions. Temperature sensor something i'll have a look at - could well be part of the issue.
Regarding ECU - I may be very dense here, but it used the Bosch K-jetronic fuel injection system, which I think is fully mechanical?
No nothing of the sort, was thinking out loud and a EEC lV ECU setup came to mindThanks for the suggestions. Temperature sensor something i'll have a look at - could well be part of the issue.

Hope you get the K jet sorted soon

Have you had your residual fuel pressure checked after leaving it 2 or 3 hours?From Cold it starts ok but rarely on the button. Normally needs a few seconds of turning over but there is some variance.

May well be the injectors slowly dribbling and leaking the line fuel pressure or the non-return valve to tank not holding the pressure in the line
The non return valves used to be only about a tenner and worth trying anyway

Am not going to be getting involved in a great debate with anyone here about the correct operation of a Ford Purple (some see it as Pink) fuel pump relay
Moving on
Does your fuel pump relay give 2 to 3 seconds priming when switching the ignition on
As mentioned above by s m, low pressure could be the problem
If the fuel pump relay doesn't give 2 to 3 seconds priming, for testing purposes it might be worth using a fused jump lead to prime the system by connecting a supply to the fuel pump fuse or fuel pump itself and check how the engine starts
Many Ford Purple/Pink fuel pump relays have given me a 2 to 3 second priming and it can be read in many Ford forums/topics that those relays that didn't give priming were replaced with new Ford relays and the new ones did give priming
Am wondering if your fuel pump relay did used to give priming and has now failed in doing so just like many other Ford Purple/Pink relays have failed in the past
If checking for fuel pump priming, the Ford Purple/Pink relay gives priming when switching the ignition on for the first time. If switching the ignition on/off and back on the relay will not give a second priming (needs to be left switched off for several minutes to achieve another priming, there must be a timer circuit or something that prevents it)
Good luck in finding the problem

What year is the car? If its an early one it wont have any relay, and will not prime the pump when the key is on. I would check the accumulator isn't leaking through the vent line, and definitely try running some injector cleaner through the system.
Does it run lumpy until you rev it and then it clears, or until it warms up? If its until you rev it, I wouldn't worry too much. If its until its warm, i'd get the pressures checked as the cold control pressure could be out of spec.

Thanks for the thoughts and questions.
It's an 83 Series 1
The lumpiness has typically lasted for a few seconds before clearing. It revved a bit lumpy, but then caught and was fine.
I think based on the feedback here and a chat with Amore when I dropped it off i'm not going to worry about it too much. If it gets worse I'll check the injectors and the return valve but it happens so infrequently i'm not hugely worried.
Best,
J

Remove the cap off the coolant header tank and 'blip' the engine. Does the coolant level rise slightly.
Always start with the basic free to check items, in your case for possible low compression.
