Hello All!
Hope everyone had a good holiday!
My brother has 2001 Ford Taurus with the 3.0 OHV Vulcan engine, and roughly 130k miles on the car.
Lately it has developed an intermittent no start condition, the car will crank but will not fire.
Initially we thought it was the battery(which I know is odd with a no start, cranking condition), but my reasoning behind this was: that the first time it happened I hooked jumpers from my car to his car, and it started fine, this happened twice, we had the battery tested at Advance Auto Parts, and it tested bad, thus we replaced it.
Everything was going fine for about a week, until I get a call, it's not starting again.
I go to rescue him, he shows that when he tries to start it, it will act like it wants to start, putters a bit, then shuts back off. It still has a good strong crank. I get in the car, give it a little gas, try to start it, and it fires right up...
Needless to say.. this has me a little confused about the direction to take..
The things I have considered are:
-Fuel pump going bad
-Fuel pump relay/fuse (I am doubting it is the fuel pump/relay/fuse since the car started with a little throttle added in tonight.)
-IAC stuck/bad (This would make since if it was stuck and the engine couldn't start because it was getting no air, thus when I opened the throttle it got air and started right up, but I would also think this would be causing rough running/stalling conditions)
-Crank sensor
-Cam sensor
-Clogged fuel filter
-Anti-theft system being triggered (Not sure how to verify it would be the anti-theft however..)
-Coolant temp sensor (PCM getting bad temp info?)
-Something PCM related
Let me know what your thoughts are on what could be causing this, thanks!
