Would not start 5 minuets after just running. Shows no spark. Cant,hear fuel pump running prior to ignition. plugs are dry. turns over fine. Can't find emergency fuel pump shut off. Would fuel pump not running cause engine control to disable spark? All fuses - relays are good.

OK: Where is that component (CKP) located in the engine compartment so I can check it? Brad

I think I found the wiring harness plug in the schematic of the engine compartment. Isn't the actual sensor just above the oil filter. I had to order it and won't be here till Tues. due to holiday. Thought I would check the fuel pump relay im between and can not find info on which unmarked relay it is. Not listed in owners manual or by Autozone as per location in under hood box. One more favor. Which one is it and do I check on a four pin relay for voltage or for continuity. Relay is $75.00 and I would have to order what I can't find? Thank you so much for all of your help. Enjoy your weekend.
