1994 Classic - won’t Start - and ideas?
Discussion
Managed to leave my phone in the house sadly, so didn’t get any pictures of the fuel pump assembly going back in.
Biggest challenge was how stiff the three rubber pipes were to get back on the pump outlets.
I use some holts rubber lubricant left over from all my Caterham builds that seemed to work a treat.

Gave the battery a quick top up charge.
Got the keys in the ignition, turned to ignition position, and that wonderful sound of the new fuel pump priming made me relived that I had diagnosed the fault correctly.
One more turn and the engine sprang into life.
Sadly, as always seems to be the case with this car, put the clutch in and the decal fell all the way to floor and stayed there.
So I now have a clutch problem to fix!

Clutch stuck to flywheel. You'll need to shock it free.
Someone else mentioned that, what method do you recommend?Start it in gear?
It’s not moving freely very well at the moment either as the disks have rusted and seized on the pads.
I suppose I could put a strap on it and yank it with my discovery?

Either can work
Thanks bud, I will give them both a go.Sadly we now have another issue that has crept in.
In that now it won’t start at all.
When it was running yesterday it sat at a very high tick over, but when it came off the high choke tick over ( I assume it’s auto throttle raise from cold) when it sank back down to idle , it just stalled and would not restart.
Today it’s doing the same thing, ie cranking and then not starting at all.
Then I remembered I bought a new fuel filter,( on your recommendation I seem to recall!) so decide d to fit that.
Now the next bit was strange,I was led to believe that the fuel rail side should have a lot of pressure on it, and there would be loads of fuel coming out when you pulled the out pipe off the fuel filter.
There was no pressure, in fact not much fuel at all.
So I fitted the new fuel filter, but did a test first to make sure the fuel was getting to the fuel filter first, a quick flick of the ignition and fuel blasted out of the pipe from the tank, so I think that means the supply is now decent.
But still we have no ignition, ie engine firing into life, so I’m a bit stumped now.
Anything stupid I may have missed?

Cheers for that bud!
Immobiliser always been suspect from the day I got the car - it’s a toad one, dint think it can be disabled.
Plugs - could be, but it was running fine before
Coils - same as above
Leads - same as above
Crank Position Sensor - as possibility - how to check?
Neutral Position Switch - a definite possibility- suits related to the clutch which has an issue I assume
Weak battery - brand new battery fitted and fully charged.
Starter motor -could be the starter solenoid I guess, it clicks a lot but does not turn over,but that could also be due to the immobiliser disabling the cranking.

Compression, fuel, spark.
Have you checked you actually have a spark?
I can’t see how compression would have changed from running yesterday to not today?Have you checked you actually have a spark?
Also you mentioned leads, assume you mean Spark Plug HT leads, if so this engine doesn’t have them as it gas coil packs on each spark plug.
Anyway I’ve called it a day now, I’ve been tying to get to the bottom of the clutch issue, so have been trying to get the intercooler off, to get access to the slave cylinder.
I’m pretty stumped on that, I’ve released all the big three bolts that mount the intercooler, but it won’t budge.
I know there is a pipe on the bottom, but I can’t get to that, so pulled the blow off valve out, to get access to the other end of the pipe, released the big jubilee clamp on that, but it’s not looking like it wants to come off.

An update on this, sadly work has got in the way so not much has been done.
I managed to get the intercooler off so I could take a closer look at the clutch.
It looks like the arm with the spring on it had seized so I freed that up with some WD40, and now we have a nice firm pedal and it feels like the clutch is engaging and disengaging too.
Sadly it won’t start and I can’t work out why. I put the battery on charge, it’s nearly new, and with the peak charger it’s back to 13v so more than enough to crank it, yesterday it would turn over, but today it’s having none of it.
It turned over once and gave a small misfire, then that was it, it won’t turn over at all now, just clicks on the turn of the ignition key!
So I’m a bit stumped now, any ideas as to why it’s stopped turning over on the key?

Thanks guys, no chance of a bump start as the brakes are well seized, another job on the list of things to do!
However I thought I would try using my spare big battery and jumper cables which turned it over for a while, then it stopped again.
So I hooked up the jump leads to my disco 4,
With it running and that got it turning over no problems.
But it won’t start, just turns over then a big bang misfire then nothing.
A few times turning it over and it sounded like it might rumble into life, but nothing.
I might check that the new fuel pump and fuel filter I fitted are actually delivering fuel to the fuel rail.
The new fuel pump is working, you can hear it spin up on the ignition.
That also tells me the immobilzer is not the issue, as if you leave it the immobilzer activates and the fuel pump stops running.

I thought I would check the supply of fuel after I fitted the new fuel pump and fuel filter.
Took the hose off that goes to the fuel rail and put the pipe in a big bottle, good job I did as when you turn the key to ignition on a huge amount of fuel pumps out, so looks like we can rule out fuel supply issues.
I will pull a coil pack next to see if I’m getting a spark.

you will need to make sure the injectors still work too...that typically makes a right mess unless you are careful. Mind the o rings they are easy to damage.Took the hose off that goes to the fuel rail and put the pipe in a big bottle, good job I did as when you turn the key to ignition on a huge amount of fuel pumps out, so looks like we can rule out fuel supply issues.
