Starting issues, help please!

New to the forums, but I have already found valuable info here(damn cabin air filter), so thanks!

My new problem is on my 2000 Taurus. About 3-4 times now, the car will turnover and crank good, but it will not start. I recently replace the battery, connections to battery, and the starter(2 years ago). When you turn it over there is no clicking or grinding, it feels like normal, it just won't start. I have considered fuel pump, but don't have the tools to test it. Everytime so far, I hook up the jumper cables to the car and 2-3 minutes later it starts. But is this coincidence? Also a mechanic I know told me there is a little motor in the fuel pump, so the jump could be powering it just enough to work.

My mechanic friend of mine suggested this next time it happens...open the intake(butterfly is what he called it) and spray ether in there. If it starts, it's most likely the fuel pump. If not, then it's probably something else.

Any ideas, tricks, hints would be helpful. I'm not overly auto savy, but my dad is good and we can fix most things together.

Read the no-start sticky at the top maintenance/repair forum.

When you turn the key to on (not to start) see if you can hear the fuel pump prime. You may need a helper open the gas cap and listen. You will hear a mechanical pump noise. Do this 5 times in a row waiting 2 seconds between cycles. It should prime (and you will hear the noise) EVERY time you turn the key from off to on.

So if I don't hear this noise every time, then that means my fuel pump is going out?

From the symptoms, any other things it could be?

Yes!

Starting after a jump could indicate a battery problem, but it might just be a coincidence that the fuel pump is starting on the second try as you said.

Also, after priming even a weak pump five times, there should be enough pressure to start the engine. I've narrowed down starting problems a few times this way. Not very scientific, but it works.

Somehow, people since 2005 have "issues."

I love helping people with problems. Biggest problem many people have is, trying to change the English language. "Issues" are NOT problems.

So, I tested the fuel pump in this mannor, and every single time you can hear it engaging. So I wonder if it could still be a sporadic fuel pump problem, or what direction to start looking in next.

Also, something to add into the fray. I've noticed over the last week or 2 of driving the car, that when I pull into the driveway/parking spot, and put the car in Park from Drive, the radio cuts off while shifting, and then starts up again when the car is in park. Do you think these 2 issues could be related in any way?

The radio thing sounds like it might be the transmission range sensor (TRS) that detects what gear you're in. It will mute the radio when it detects you are in reverse. May or may not be normal.

I guess I would be focusing on the battery since jumpstarting was helping it. Get the battery load tested somewhere (preferably besides AutoZone).

I just replaced the battery less than 2 weeks ago, and it has happened once since replacing the battery, so I don't think it's that(would mean 2 bad batteries causing same issue)

As for the TRS, it's doing it in every gear and not just reverse, so I'm wondering if there is something wrong with that. I know they aren't too expensive, and not very hard to change.

I just wondered if there was any way those 2 issues could be related. I really don't feel like spending 100 bucks to have someone hook it up and see if the computer gives out any codes from the last time it wouldn't start, but I might be at that point. Local shop near me told me 90 to hook up and then diagnose.

Sure sounds like the TRS failing.

It could be a sticking Idle Control Air Valve. Next time it won't start, slightly press the gass pedal to open the throttle plate. If it starts and if it dies when you fit the foot off the pedal it is most likely the ICA Valve.
