Hi everyone. I was having an issue with the Explorer SOHC 4.0 not wanting to restart when it was warm. Was cranking fine cold (other than needing new intake seals-thats next) and most times it took 2-3 tries to restart it when warm. Then suddenly one day it didn't want to start at all. I kept trying and started cycling the key on and off and it eventually started. I replaced the temp sensor and it seemed to have corrected the problem. Now 2 or 3 days later I went out and it won't start at all. I tried cycling it from off to on up to 10 times but no. I've never been able to hear the fuel pump prime up in the past so I got someone to turn the key on while I was at the fuel door, put a transmission funnel in it, put my ear to that and heard zero when it was turned to on. I also swapped the relays so that's not the problem.
That really make me think it is the fuel pump ( I already have as a just in case thing) but don't want to pull the tank unless I know for sure that's the problem. Any other test I can try. I searched the Forum but can't seem to find the right answer. Thanks for any advise you can provide.
OK FORGET MOST OF THE ABOVE UPDATE UPDATE UPDATE
I did pull codes on this a couple of days ago and saw a code that said PATS had disabled the engine. I was confused because it the same key I have always used with no problem so I ignored it as a fluke. On a hunch I went out with my spare key and it started almost immediately. Tried my usual key again, did start after a couple of seconds. Tried spare key again, immediate start. Tried original key again. Delayed but it did start. Could something funky be going on here? Any ideas would be greatly appreciated.
