    I have measured the resistance of the key an used a resistor of the same value to bypass this part of the security. When I first turned the key on I could not hear the fuel pump. I seem to have 12V at the coil the injectors and the fuel pump but they do not seem to receive the ground signal.The computer has been changed with engine.does the computer keep this from happening because the security light is on?

    Thanks ! I have bypassed the fuel relay but the car still did not start.It seems that the computer is not supplying the signal for the ignition or the injectors.

    The car engine turns over now as I found the problem with the security light.the problem now is the fuel pump does not activate when the ignition is turned on. 12V is present at the injectors and at the ignition module. It is also present at the fuel pump relay.there does not seem to be a signal to activate these things

    The problem of the engine turning over has been solved.The engine has a crank trigger so thus no distributor. My problem now is that when the key is turned on the fuel pump does not activate. There is 12V going to the relay the ignition and the fuel injectors. There does not seem to be a signal being sent to provide a ground for these.I have checked the plugs to make sure they are connected. What I need to find out where and how the signal gets to these items

Relearn the key fob,,turn the key on,leave it ten minutes,then tun it off,and right back on,leave it turned on ten minutes,and turn it off,and right back on to do one more time,a total of 30 minutes,then the key fob will be relearned.

Hi! Please check the connection of the MAF (mass air flow) sensor. It may need to be reconnected. Check the timing of the distributor too for it will require correct timing for it to turn over. Hope this helps and have a good one!

Hi!!

Under dash, by steering column, there is a Theft Deterrent Module (a relay looking device) that controls the secuity of the vehicle, use a wiring schematic to bypss this function and you'll be OK.

If you change the motor and not the computer and/or the ignition switch, This happens, the computer does not recognize the key, have been told that you have to change the three things together.

Click on this link to get a wiring diagram for your vehicle:

On the wiring diagram Fig. 4 you'll find the device I am talking about.

Keep me posted. Appreciate rating this post, Good Luck!!

    check the fuel pump relay and bypass it w/jumper wire, just to see if that would do the trick. If it works, check what's needed to activate relay, 12v or ground and if it is ground, get it from car body, if it is 12v get it from fuse box but activated when the ignition switch is in RUN, otherwise you can mess up the fuel pump.. It seems like you know what you're doing. so wire it the way you think will work better for you. I'm just giving you the general Idea.



    Please keep me posted, I really want to know how it worked out.

  • Rene J Solis Apr 25, 2010

    About the light on dashboard, I don't think is what's keeping it from starting, it is just telling you that the computer does not find the right signal to unlock the security system.



    And again, bypassing the signal, will not harm the ECM

  • Rene J Solis Apr 25, 2010

    Allright! Just remember, you need to supply power to the ignition module, maybe from same place you got the juice to the relay.



    I beleive that the motor starts, the sensors will be sending the signals and the computer will take over. If it is not sending juice to the ignition module is because the security device is not sendig the right signal. I'm just using common sense.



    I wish I could be of more help, but I know you'll get it running, thanks for keeping me posted.

Hi all,I've got a 1999 Pontiac Firebird and I need step by step instruction (please) on how to replace the spake plugs. The engine is a 3.8


You have to get 3 of the plugs from underneath the car, and you will also need extensions and a swivel-joint . Good luck, it's a tough job! 3-5 and 6 you must get out from under the car. 1-2 and 4 you should be able to change these under the hood.

I have a 94 pontiac firebird the security light comes on now i wait 3 minutes and it will start sometimes i have to wait 2or3 times to get it to start when the light is on it does nouthing


(from autostalk.com)
I'm pretty sure I know what the problem is, if you have the keys with
the small 'computer chip' on the black plastic part then your car is
equipped with a sensor in the ignition (where you actually put the key
into) that is supposed to be able to sense the key, to make sure its
the real key. In many cases, the wires from this sensor become loose or
faulty and will trip that light.

Blower motor is not working. Will not blow a/c


If you have power to the blower motor, and it still doesn't work, the problem is indeed your motor. If there is no power, it could be a fuse, switch wire... etc. You will either find the blower under your dash on the passenger's side behind the insulator panel under the glovebox, or under your hood. Your's, i am quite certain, is under the dash. Some are pretty easy, some are not. It is held into the hole by three bolts, and then you just pullit down. When you buy your new one, either get one that has the fan part on it, or ask them to change it for you. I would suggest you buy a complete one. Take your's in with you. They should give you something for core. Good luck. Don't be afraid to ask for help.
