Test all your fuses with a test light and then check the ASD relay and it's power supplies. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Check thoroughly to see if the plug connection might be bad or the pick up in the distributor could be bad and cause a no spark. Check the starter and ignition relay also, or there could be a problem with the PCM. If so check it with your dealer.

Jeff Collision, stop posting your wild nonsense. If you don't know what you're talking about, don't post. The OP had a very specific symptom and most of what you suggested has no connection. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

Thanks for your response. checked all the fuses with test light on both sides all are good (assuming there is only one fuse box). Checked the ASD with key on there is power at two of the four pins. Ran continuity test on wiring from engine compartment to fuel pump everything checks ok. Noticed the ASD buzzes for a moment when the key is turned on. Replaced the relay no change. Suggestions?

This gets a little complicated so you may have to get it diagnosed One thing to remember here. the ASD relay only powers for 2 seconds when the key is first turned on so make sure you are checking it right. Use a fuel pressure gauge to check fuel pressure. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
