Normally the problem like this is caused by faulty starter relay.This can be solved by replacing the starter's relay contact mechanism.After a prolong time the starter relay contact mechanism will get worn out as a result of arcing.Check also to make sure there is no loose cable at the connection.

it has to like your key, that is its #1 purpose,
first is to check all fuses. there are many fuses related to
the antitheft option.
clock dome fuse? and C13 fuse (antitheft)
this module kills the starter relay dead. (can be bypasses ask)
finding a 2nd key or fixing antitheft on any Isuzu (they bugged out in usa, )
can be hard finding support for isuzu, in usa, (like Yugo,Daewoo,and suzuki.)

try my hack.
this blu wire if grounded, enables the starter relay.
give it a try.
theory, when the Anti box likes your key.
it grounds pin28 and the starter relay wakes up.
the key start wire powers the starter relay on its other coil pin.

1996 Subaru legacy with 5 starters replaced since June 2011. Still not starting normally. Will generally work for 2 weeks post replacement and then nothing when the key is in the start position. ...

I really think you have some other problem going on that you think is the starter. Maybe a starter relay. Does it just not start when it is warm and after it sits it starts? Does you remote starter switch bypass the key switch and go straight to the starter and then it aways cranks over. That would indicate to me that something is either wrong with the key switch or wiring to the starter relay or solenoid.

    I just recently purchased a 1996 cadillac el dorado etc. it starts then shuts right off. i dont know if it is something wrong with the anti theft system. maybe the keys. i need to know how to check this. i...

    Heres the deal. When you put a remote starter on this year Cadillac (and about 100 other GM models) you have to bypass the security system. On these vehicles, that chip in your key has to communicate with the ignition/lock cylinder and then the TDM (computer) to allow your starter to start and/or allow the injectors to continue working. So what people will do is "bypass" the key and lock cylinder to fake the TDM into believing it has the correct key chip inserted. This allows you to remotely start a vehicle with an antitheft. My guess is that your TDM has now failed. Since the remote starter (which is hooked directly to starter) works and the key doesnt AND we already know that the system has been altered.... I'd put money on the TDM (theft deterrant module). Check out this link. You'll find an answer to your problem for sure.

    on the relay there will be a small wire that gets power when you turn the key to the start position
    find that wire and connect it to the small terminal of the starter solenoid
    then if you get it right , when you turn the key to start, power will get to the starter solenoid , energize the solenoid and the starter will engage
