Right my SPI wont start and the only thing i have yet to rule out is the immobiliser, however i do not have a key fob, all i have is a ignition key, and two buttons on top of the steering column next to the wee red light that wont go off. playing with these buttons i can occasionally make the hazard lights flash. so i must be on the right lines.

can anyone enlighten me as to what combination i need to press todisarm the immobiliser and start the car?

car started the day i bought it, but hasnt run since, its got a clifford alarm also if that helps.

if you can help but dont want the combination to be common knowledge pm me, i can even send proof of ownership if you need it.

if you dont know but know of someone who will or might i would much appreciate any contact details.

Thanks in advance of help,
James. :proud:

could you not ask the previous owner as to why it wont start?? why doesnt it have a key fob if it needs one to dissarm the immobiliser, one way you can get an auto electrician in to sort it out for you.. just have to prove ownership of the car etc.. you can probably guess the reasoning for this! my immobiliser is just turned of using the key fob button red flashing light (immobiliser on) no red lgiht immobiliser off :)

I have tried them, but theyre about as much use as a chocolate mantlepiece. car had been sat for 4 years, but with some new petrol and a bit off extra battery juice from my van it started and sat on tick over for about 5 mins. went to collect it 3 days later expexting to drive it on to trailer and it wouldnt do feck all!

I cant remember if the immobiiser light was on when it was runing that time or not.
so far its had,
Completely drained petrol system, new filter etc.
New Plugs
New coil,
and a hell of a lot of swearin!

when i come to restore it it will get a new front loom as but untill then it would be good to have it running as thats at least a year away. and with no permanent space for it need to move it now and again.

oh well, you get what you pay for!

I don't think your problem is the OEM Rover alarm

.......... two buttons on top of the steering column next to the wee red light that wont go off. playing with these buttons i can occasionally make the hazard lights flash. so i must be on the right lines.


........... its got a clifford alarm also if that helps.


I think the two buttons are related to the Clifford Alarm you have fitted. Certainly the original Rover alarm never came with these.

Are you sure the Clifford alarm is disabled ??

Can you remove the Clifford Alarm.

If you are sure it's not active then the question is whether the person who fitted it did anything with the original alarm. From standard there where two types of Rover alarm the 3AS and 5AS. I believe the majority of SPI's were fitted with the 3AS. This is connected to the door light switches. If active the horn should sound if you open the doors. I assume you are not getting the horn sounding. If not I'd say the Rover alarm is not active.

I'd check on-line to see if you can find how the Clifford alarm works and make sure it's not this that is causing the problem

Cool, that all seems to make sense, the clifford one is definitly active, but the best life i can get out it is when you connect the battery it beeps. No horn when i open the door would mean that the rover one must have been disabled (or never maybe existed?) when the clifford was fitted?
when i bought the car i was told they would have a look for the clifford documents and send them on, but so far have had nothing.
I could remove it, but i dont know whats standard and whats with te alarm.

Thankyou for the most usefull reply i have had so far (second or third thread so far on this problem). Thanks! :D :D

Right, i have found the alarm manual on the clifford UK website, and according to it the red light being on solid means the alarm is in Valet mode. which will allow the doors to be opened etc, but not started.

whats bugging me is that i am getting healthy spark and petrol,m but wont start.

The manual should also tell you how to disarm the alarm without the key fob. Normally you have to switch on the ignition and then toggle the valet switch, some of those alarms also have a special pin code.

might sound stupid but mine cuts the fuel pump... can you hear that tuning on like a buzzing noise from the fuel tank area when u turn ur ignition on? if not it might be cutting the power to the fuel pump stopping it from starting.. also check earths for the fuel pump mine came off once and caused me all kinds of headahces ahha!

Got Remanufactured ecu back from ATP today, and she still wont go! Fuel pump is running, and dash is lighting up as it should, so thats an improvement, but when i turn the key right round, nothing happens, is it likely to be a fuse now? will have to go tripple check them, any idea which one it should be?

tried crossing the starer, it spins but has been sat so long and wont fire the pinion out, will get someone to help me chap it when i get it on the key.

any suggestions?

When i try to start it, ingnition on, the pump is purring away, then stops as soon as i turn key right round. Should it be doing that?
Nothing clicks Anyone know what might be wrong?

could it be the relay pak, the underside of its board is quite corroded?. but i wouldnt say excessively.

All help appreciated, if any of you spi Gurus are out there reading this, would be glad of a chat on the phone or two, would return the gesture in any way i can.

:) James.

Try disconnecting your negative battery terminal
Then stick your key in ignition in the "on" position
Then reconnect the neg on the battery. This should instantly put the alarm in safe mode & start the car ?
Also have you checked the condition of the battery power. ?

One of my friends had an impreza with a Clifford alarm & immobiliser which broke & left us stranded Turned out the immobiliser cut the fuel pump. Luckily he had some dodgy wires for a sub woofer I removed & took a straight 12v feed from the battery to the fuel pump to get us home :).
Is your alarm the Clifford g4 ? There is many forums obline of people having starting issues with these! Of you still can't start the car after all else fails there should be a connection of the alarm to either fuel pump starter or ignition. Which you can remove & re wire without the alarm on between I'm guessing yours won't be the starter disabled as you say it's turning over ? But I'd say it would possibly cut power to spark under any Kind of load . ?

Is it a starter fault? Motor, solenoid, relay, switch?

Ok, sorry, should have explained clearer, ECU has been for a holiday to ATP electrinics and is now free running, i.e it doesnt rely on the alarm anymore, and th immobiliser is disabled.
Car now wont turn at all.

which relay is it for the starter? was trying to listen for one clicking, but couldnt hear anything?

Lifted the following paragraph from th sticky about relay pack functionality.

"The main relay is grounded by the ECU (white with pink), the fuel pump relay is grounded by the ECU (black with purple), the manifold heater relay is gounded by the ECU (black with pink), the starter relay has two options depending on year. One, the starter relay is grounded (black pin4). Two the starter relay is grounded by the alarm ECU ( white with red). Note the latter, the wire from pin4 of the relay pack changes from white with red to white with pink, through the body to engine loom connector."

with the starter relay being grounded by the white / pink wire, as i have removed my alarm and decoded the ecu does this mean the starter relay wont be getting grounded? (car wont start, could that be why?) should i connect the pink and white wire to the body?
