Ive got the problem down to spark. Whats throwing me for a loop is no codes are appearing. Checked camshaft sensor. It still functions. Replaced ignition coil and module. I reset computer and dont show a theft light. I feel that a car that old should have atleast one code. Weird. Im thinking ecm. Even though no issues beforehand.

Yeah that's what i Checked "crankshaft position senor". I've checked it with a multimeter. Shows voltage. More on warning lights. The check engine light is on but has been since I've owned it. Unless there is an issue with the OBD hook up. Then No codes. If you want i could send you a couple pictures. I just don't think it'll help much. Test light doesn't show spark.
