Installed new pcm modult on olds 88 made 1998

Unplug computr n clean pins they git corroded. The coil cud b worn on that old car. If it has a distcap clean inside or replace. Chec wiring under fusebox for burnt Relay cud be bad or fuse. Ign module also. Make sure its gittn rite fuelpressure. Buya haynesbook at parts

Open the fuse box under the hood and swap the PCM power relay with the Fuel Pump Relay. It should start. Buy a new PCM relay and put the good relays back into their original positions.

You need to take it to the dealer or have a mobile lock smith program the new key's . Transponder chip in the head of the new key . If the computers - PCM / ECU an the BCM do not get proper code it won't let the vehicle start .

Have you had the system reprogrammed? The security system is locking you out.

you might try unhooking battery post from battery and leaving it like that for at least 30 minutes and if that dont work. Try to start the car and when it doesnt not start leave the key in the on postion for 10 minutes and the turn the key off and then when you try to start it again but be sure that you use the clock that is in the car to count the 10 minutes with. we have to do this with my wifes old 2004 chevy malibu classic. hope it helps

have PCM check sound like PCM CHECK PCM FUSE.

is there a check engine light, possible mass air flow sensor

sounds like your convenience module is on the fritz

I have the exact same problem. Fuses look good, I have no idea what the problem is?

You need to change the locking mechanism on the door,not the theft lock that you push down by the window,the lock that keeps thew door shut.I dont know why it wouldnt lock,it must be a factory defect,that worn out before its time..
