corsica no code won't start when warm

Won't start when car is warm & sometimes dies when driving Engine check light does not come on, when it wouldn't start sprayed starter fluid still wouldn't start. Have replaced crank sensor. Any suggestions.

If it won't hit with spray it is not firing. Since you have replaced crank sensor, the next thing to do is remove the coil pack assy, which is the coils and the ignition module. Depending on your motor this is not too hard, but you have to remove together. The ignition module it flat and has wires running into it. The coils sit on top and have the spark plug wires running to them. if you have a 4 cyl. it sits in back of motor, if you have a 6 cyl; then it is either down low in the front of motor, or possibly on top. Depends on motor. Most TBI 3.1's have them in an easy place to get to. Remove the assy and remove the coils (2 on a 4 cyl. and 3 on 6 cylinder) and take the ignition module to Advance Auto, NAPA, or most any good parts stores. They should be able to hook up to a tester and advise you if bad. Costs vary but should be 80-100 bucks for the module. Do NOT buy a used one. Some people will replace the coils too, since you have everything out, but that is up to you. Might prevent you from taking it back apart later on if one is getting weak, but again, it is up to you. If money is tight and car was not missing re use the old ones if you wish. They can cost 20-25 bucks each.
