    Thanks for your response. The trans that I replaced has 1 circular 14 pin male connector. the wiring harness has two female connector one has 8 pins the other has 6 pins. i cut and spliced the circular connector and put the square connector on it all the colors matched except 2 does that mean that the wires are all going to its respective circuit or do i need to find the wiring diagrm for the trans with the 2 connectorand if so were do i find it because i have alldata acoount on this 94 and 93 models none show 2 connector for trans in fact all cadillacs if looked up has 1 circular connector im in a bad way been working on this car fr 4 to 5 months and im sick can you give me alittle more insight pls and thank you

That will definately cause the car from starting. It will send an error code to computer. Almost any sensor malfuncion could cause a no start. crank, cam, and any temp sensor are most common culprit in the 8 years of my mechanic experience

While cranking loud backfire than i restart engine again than it cranks than starts up,this happend about 6 times during 3 months. Car did same thing yesterday, but it just cranks won't start 98 olds...

Not sure if you have a 1996 Cadillac Seville or a 1998 Olds Aurora but I would check the Ignition Coil Packs. One or more of them may need to be replaced. Also if you were working on the car and got the wires plugged onto the wrong coils then the firing order sequence would not be correct and this can cause a misfire or backfire conditon.

Ignition wires cannot rest near the primary wire harness of the ignition module, which can cause electrical interference and a no start condition or a misfire condition

On my friends 1997 Cadillac Seville it was easy to replace all 4 coil packs took less than 30 minutes and made the car run much better. Just make sure to get the firing order right. If necessary find a diagram of the correct firing order for you vehicle.

A good place for mail order auto parts is

I have pasted a picture below of what an ignition coil pack looks like

Electric problem

this could be a factory wire harness problems, generally over time the plugs ie connections get warm and tend to crack causing shorts which can lead to electrical fires i would check all connetores under dash and on main harness in engine compartment for discoloration which is a good indicator of a problem.
