Toyota camry

Hi i Drive 1994 toyota camry 4 cylinders,automatic trans. the problem with my car is it will run for like 15 to 20 minutes, and then dies out, i checked for spark, and there was no spark, so i changed the igniter, but still did it, so i try with changing the distribuitor,and the ECM, but still dies out, last thing i changed was fuses and relays, but nothing seems to fix the problem, i don’t know what else to check, i run out of ideas. Please help me.

Check all the electrical connections at the distributer, coil packs and alternator.

You may have a fault in the ignition System itself.

I recommend you invest in a test light probe and service manual to help you find the problem. It may be in the ignition switch area or a rely problem.
