My 1991 corsica will not

Check the crank sesor located on the back of the engine between the transmission tail and engine you may have to remove the thrans/motor supprot plate to see. that is the most common no start ploblem. If I may ask why did you change the timing chain?

I just solved the problem with my Sons 1996 Chevy Corsica's engine would turn but not start, I changed the electronic coil wich is what the 96's have instead of a distributor cap. it is the part that the spark plug wires attach to. My son's car IS A FOUR CYLINDER so he has two electric coils, however only one was bad. the coils sell for around $24.00 each.
