Ive also noticed that the alarm doesnt seem to be comming on. i wondered if it was imobalising. every time ive had battery of in past the alarm has gone of when dash sets itself (needles go to full) but not this time! any helps????????????

check that you have not missed off anything,the sensor above the aircon pump near timing chain is most likely the cause.

everything is in place, and have noticed that the plugs are dry. would have thought they would be wet with not fireing! anyone know how to check that inj are working?
also can anyone tell me how to set my alarm off cause i think its not working. can it switch the imobalizer on with still allowing spark?

thanks for the help!!

Hi if you have had the battery disconnected its worth checking that all the wires are back on as sometimes one can be missed very easily causing all sorts of problems regards malcolm

One Way is to
Lift bonnet and put finger on the spring loaded button to simulate closed bonnet. using keyfob activate door locking and wait for pats system to activate (10 seconds or so) then simply remove finger as to simulate bonnet being opened, alarm should then activate.... :o

thanks pete will try that! have now found that theres no fuel being pumped. does theses scorps switch pump off if censers arnt working. but even then would they not still allow pump to work on ing 1 position?

Check the fuel cut off switch located on the boot slam plate left of the catch. It's a red button which is designed to cut fuel by an inertia switch in the case of a crash.... can sometimes go off willy nilly...

I was just going to suggest the same pete.My old 16v had the same problem.Took me hours to realise this though :-[ ::)

This could also be caused by a problem with the signal from the ECU to the Fuel Pump Relay. This signal provides a 12 volt supply to the pump safety switch and then to the pump. This signal is provided from the EDIS unit to the ECU (black and white wire) and can be checked as follows: -
Pin 1 EDIS to Pin 48 PCM (ECU) - black and white
A four channel scope
Channel 1 EDIS positive - Ignition feed
Channel 2 EDIS ground
Channel 3 PIP signal
Channel 4 Crankshaft Sensor

good luck

Hi there!

Check the fuel cut off switch to start with as Pete says. You can tap it sharply with
a rubber screwdriver end or with something else, but don't go hammering it with
a force. It should pop up when tapped, then press it in again. You can do that
a few times around to make sure it's not sticking.

Having had the same problem in my 24V to 16V lump swap, I could give you some
other pointers:

1) Check the battery junction fusebox, turn on the ignition and wiggle relay No. R17
( See this link: http://www.fordscorpio.co.uk/images/battery_fusebox.gif )
If there is a faulty connection in it and it's not that rotten, you should hear the
fuel pump activating.
2) Check the fuses in the battery junction box with a multimeter, or you may even
construct a lead with a 12v lightbulb to find out if there's power to the fuses
No. 42, 33, 34, 37 etc.. At least all these have something to do with starting.
3) When you turn on the ignition, is the alarm/pats led glowing for about 5 secs
and then going crazy, blinking like a madman and after about 20 - 30sec, settling
to show an error blinkage (one flash, pause more flashes, pause ... ). If this happens
it's a pats related problem -> PM me and I'll tell you how to get rid of that (Thanks
to KIMI! )

I had a rotten aux. fusebox which had worked just well until I started my engine swap
project. Gave me a lot of headache before I realised that it was actually failing. It is not
very hard to take it out and have a look inside and underneath it. There are a lot of
leads and plugs, but they are idiotproof - you cannot insert them into wrong places.
So you can safely disconnect them. It's not a nice task, but then you know if you have
a fusebox problem. My alarm never worked before I changed the fusebox. I always thought
that "funny, there's deadlock, but no alarm" because the led never started blinking when
I closed the doors and set the deadlock etc. Now it works. After swapping the fusebox!
Granny's auxbox will do the job if it is at least -93 or newer. i changed mine from a breaking
project granny. It happened to have a new box! (I wonder why... ;D )
