Computer problem

Engine starts and runs only for few seconds. We tried letting the ignition key on for 10 minutes. Also we disconnected the battery for 5 minutes. Nothing works. Thank you for any help.

Yes, your theft deterrent system has shut the fuel off.

P1626 Theft Deterrent System - Fuel Enable Circuit

Follow the guide below on relearning for the anti-theft system.

Sometimes the wires that go from the lock cylinder to the anti-theft module break.. this keeps the system from being able to read the key

We have erased the P1626 & P1632 codes. The engen started and ran but when we stopped it, it will not start again. I Don't know if this might be connected to the problem but the electric door locks don't work.

We are not able to activate or deactivate the alarm system

Its your alarm system, it has to be looked over, something its doing that is shutting down the fuel. Check the the fuses for the door locks, it will probably happen again, because I believe a fuse blew. So check the door lock fuse

I have checked the fusses and they are all good, however, there is no power to the three lock relays. What can you suggest might be the cause?

Can you activate and deactivate the immobilizer/alarm system? Check the relay for the theft system

With the three door lock relays not receiving power the transmitter will not work. Again all fuses are good, all codes were erased, it started and ran until we shut it off, now it wont start again. Sme two codes come up again (1626 & 1632) Its the theft system. The question is how do I reset it?

Right, it is the theft system, but all cars are different, so if you do not have the vehicles manual. You will need to go to the dealer. I really hope you can locate the manual. As your gonna have to pay just to do what you could have with the manual. Also make sure the battery is good in the transmitter

Do not know what BCM stands for? Read about it on your site.
Starts but does not run.
Now the instpanel kites of all the problems. Do not light up.
Been thru all the fuses. Some were corroded on the left door side. Used the proper stuff /anti static and put all back in place. Pulled and checked fuel pump fuze and relay. Nothing.

Guess I will try the "relearn" for BCM. But won't know when the theft light goes out cuz it doesn't lite up.

Thnks
