I have a 1989 Olds cutlass ciera with a 3.3, distribuless ignition. It will not start, it is getting fuel (almost caught the car on fire), it has plenty of spark, has new spark plugs, new control module, all three coil pack are firing. It acts like it wants to start but doesn't. I also chage the crank sensor with a new one. How can I check the timing on this car with no distributor or timing marks, without tearing down the front end and checking the timing chain? Any help is greating appreciated.
