Randomly will not start

2001 Ford Taurus has starting issues. Just replaced starter a few months back. When that was going on it wouldn't make any sounds just a clicking. This time around everything sounds right but its not turning over. Sounds like it is trying but can't complete. Doesn't happen all the time. Most of the time its fine. I have noticed each time the heater has been on. Not sure if that has anything to do with it but figured I'd point out. I usually always have heater on anyways since we live in colder weather. Car has 133k miles on it. I've owned it for the last 20k or so. I've kept regular maintainance on it. I'm a bit stumped as to what's going on any advice is great. Thanks!

Security light? The red letters that say theft is solid. According to another response on a page I can't seem to find now it said to listen for fuel pump turning on. I have been doing so and everytime I hear something engage that I assume is the pump when I turn the key to the on position. It just happened again and now I could not get it to start even after waiting a while. Also when I place key in on position I'm not hearing the sound I assume is the pump. It turned on for a second then died and could not restart. Could that be a fuel pump symptom? Is it a fuse? Relay? How can I tell? I appreciate any help. Thanks!

The reason it wont start is because the theft light is on. What is the 8Th digit of your vin?

I considered this being an issue as I've encountered something like that before due to other keys on my key ring. Now I have it on it's own. I thought though it had to be flashing if that was the cause. Honestly this car seems to be too high tech for me, lol. The 8th digit is a letter You. If it were the anti theft system would that cause a. Intermittent problem not consistent and b. To start up and then die within a second?

The 8th digit of the vin tells me what engine incase I need to know that. The first step is see what codes you have that way we will have a trouble tree to start with. The codes were looking for start with the letter B followed by a four digit number.

I have checked codes like check engine light. All I've gotten is EGR valve but that's been there for a little while. Don't think it's the cause though I could be wrong. As far as I know those are the only codes I can read. Now weird thing I read about rolling it for a bit and it can reset the system somehow. I don't know but I've tried it all 3 times and it has worked. This last time I paid more attention and heard a click like the wheels or something then tried and car turned on. Now this could be unrelated. Just thought I'd include any info that could pertain. Now just to rule out pump itself: if that was bad then wouldn't car also be susceptible to shutting down while driving? Which it doesn't do. Ok thank you

The egr valve has nothing to do with the theft light on and a no start. Also if the theft light is on there is no need to check the fuel pump because the car has been disabled we know this because the theft light is on. So you have relearned the theft in the past and that has gotten the car to start in the past?

Yes I read a post from someone somewhere and like I said it mentioned rolling. So I put car in nuetral and roll back then forward. It could be a simple coincidence, but the 3 times this has happened in the last couple weeks it has worked. After rolling I try again and voila car turns on. Today I will be testing fuses to see if theres a bad one somewhere. Other than that I don't know where to look. Wires somewhere? I've read you can't disable the PAS II. I've also noticed that when car is off and locked and security system set it will at random let out a few beeps. Though no one or anything is toouching the vehicle. Could that be related. I feel like there's a short somewhere. It's my assumption the system is connected to the vehicles battery so I don't see it being a low battery unless there is another one somewhere I don't know about. I haven't had battery checked recently but 2 months ago had Les Schwab check it and they said it was good. Getting really lost on where to go from here. With as much as I drive this is a huge inconvenience and loss of assurance.

It cranks and everything sounds like it should, but won't start. I also do not hear the fuel pump turn on when I put key in on position like I normally can when it does start. This not engaging is why it doesn't start I'm assuming. When I do hear it turn on car starts no problem. So essentially I'm trying to figure out what could be causing it to not engage all the time. So far it's happened 3 times about once every 5 days. Aside from those times it works just fine.
