only 2ways to regress any alien alarm on a car.

notify manufacturer --local installer ---or ask old owner

Most factory remotes have the car makers logo on them. Aftermarket will either have nothing or a brand name like Viper, clifford, avital, DEI, etc.

My best advice is to contact clifford direct and explain your problem normally very helpful.

go back and have installer check and test system

Most audio mobile mechanics are trained in installing alarms as well as other things on cars part and present. It would be worth finding one and enquiring about your alarm. When you phoned Clifford I am guessing that you spoke to the receptionist and they just looked it up on their computer as the model is not stocked they probably won't help as it most likely wouldn't of had any warranty anyway. I had a 97 corolla and it had a stock alarm on it and it was good. Good luck anyway. If you are not confident enough don't touch as electrics are tricky on cars specially when taking advice that is noteface to face at the problem.

I am sorry but we have no electrical diagrams for any alarm system.

Look under the dash for a little button that youll push to bypass the alarm. If not one you will need to disconnect the alarm sysem and remove it. It is useless to you anyway without the key pad

Find where your fuel pump relay is and check for power there. Most alarm tech's and alarm system dis engages the fuel pump at there relay's.

Simple things to check is the fuse first then go for the relay and if everything there is working properly, it could be your alarm may have gone bad or your fuel pump it self.

Good luck and hope this helps
