alarm/immob reset?

[baggiero]

Hi all -
old-style locking Chim 4.3, battery flatted by alarm due to me not driving it for a couple of weeks (and probably a bit of a knackered battery to start with)...
recharged battery (in house) and re-installed.
..
Alarm re-activated, fair enough.
Try to unlock/deactivate. (by key) - doors clunk unlocked, and the clunk locked again immediately...
Left it for a bit/fiddled around, tried either door .. seemed to "calm down" to the point where it would unlock, but on trying to start (unsuccessfully- battery not giving out enough juice) and then giving up, the car locked itself again (and armed the alarm, with just enough time for me to jump out again over the windows...

any comments/ideas?

Knackered battery and low volts screwing up the alarm ?

just had my alarm rewired by an autoelectrician which seems ok but i notice that the fuel pump runs all the time with the ignition on where as before it used to run as though it was priming the system then stopped untill engine was started ,is this ok or is there a fault.

Its a fault. The ECU fuel pump control has been bypassed so that the pump is energised permanently. Got good but not fatal.

re. original q. - yup, Steve was right (no surprises there..) - new battery installed, all is well again.
Wondering what people reckon is best non-alarming (ie. non power-draining) method of immobilisation? Since I've got the old door locks I can lock the doors mechanically anyway.

My ideas so far:
- remove/unplug lead to centre of distributor (presumably bad for cats as would (If hotwired) send fuel through unburnt)
- fuel pump fuse removal (assuming there is one) - more or less what the immob. does anyway?
any other good 'uns?

ok so there is a fault so how can i wire it so the ecu pump control is not bypassed as i do not have a wiring diagram ,any help please ,and does it harm the system being like this whilst the engine is running .not having a wire digram makes things dificult .and can i get a diagram from somwhere as i cannot get hold of the chimaera book at present.

I know this isn't the most helpful of responses but isn't it time to give the problem back to the autoelectrician that created it in the first place? The Chimera wiring diagram you'd like to get won't have amendments to show what the autoelectrician has done.

Hope you manage to sort it out before you knacker the pump.

That is right. The diagram do not have the alarm system in them. If the pump is energised then it usually means that the live feed to the pump is diecrtly connected to +12 volt instead of getting its power from the fuel pump relay. I would go back to the auto electrician and say "this is not right"
