I dont know :bang:

It not as far as I can tell a common code on a fiat and this engine is over 15 years old

I found a few threads where this, that and other has been changed, then the threads have gone dead.

Examiner doesn't report this code as low fuel pressure ?

If you clear the code, does it come back.

Not even 100% its not caused by the long cranking ?

I am guessing and dont see an easy way to progress. Testing the fuel pressure with the injectors disconnected would be the way to go at a garage. This would instantly tell if either fuel pump were faulty.

Oops, sorry, thought my post hadn't taken! No, I meant I'd tried the removing fuel cap in case a blocked valve.

Have a look at running a injector bleed back test lots of how to's
on Utube if you have a bad injector the pump wont be able to
get the pressure high enough,

My 100HP did the refusal to start thing last summer after being laid off for weeks due to the Covid lockdown. Battery was charged everything ran as it should - engine spun over as it should but there was not the slightest attempt to start. MES refused to work which had me running around for days trying to fix the computer (see more later).

After checking fuel pump, coil, plugs, ignition switch and individually testing every fuse in the car, it suddenly started working and hasn't looked back. The one oddity was that OBD socket was dead - no power. I never found out why, but that's what was killing the car and why my MES had appeared to be faulty.

Check you have power at the OBD socket. AnyOBD tester will do. The issue is a faulty connection somewhere. Best of luck finding it but at least it's consistent so worst case an auto electrician will be able to find it.

Hi again!

Well, seemingly the local garage put it down to a relay (T10 I believe). Anyhow, that seemed to do the trick though they replaced fuel filter first on the off chance which majes sense. 4 weeks later though exactly the same happens. Slight falter when in top at about 50mph after a few miles and the engine light comes on. Makes it home by not stopping the engine and once home stop engine and it will then turn over but not fire - as before. Link up code reader and it's my friend P0087 with the punch line of "fuel rail / system pressure too low". On swopping the high beam relay (T02) and T10, which are identical 20A ones, the engine fired up!

I have a nasty feeling it will end up being the fuel pump!

See you all again soon with the next exciting installment .....

Did the tank pump still whirr ?

It just might be a bad connection in the fusebox that is affecting the power being delivered by the relay. Swapping them about being enough to improve the contact. See if you can close up the female contacts (within the fuse box) that take the relays.

This might also give some clues. Used pumps about £50 to £80 regulator £45.

Here's the pump seal kit. Worth a punt at £17.75, if it's all that's needed to refurb the pump.

We,

The garage fitted a new OEM relay and said they couldn't find any other possible causes. I guess this might tie in with the suggestion about checking the state of the fuse though it remains a question to me of "if it needed an original relay refitting then why did the one before fail?". Oh well. i guess this is thejoy of running a vehicle over a certain age with primarily electrical rather than mechanical systems. Don't even get me started on clutch pedals which can't be adjusted!

Why would you need to adjust a hydraulic clutch pedal?
If it's out of the normal range it means something is wrong such as the clutch being very worn
It's not like a cable that can stretch a little

You can get a used replacement injection pump for £50 to £150. It may well solve the problem. If not you can get the original rebuilt.
