Car will not start

Thank you very much.

I have tried to see about getting this car running, it has been sitting a little over a year under a open carport. It is not firing. I have replaced the coil pack. I am not sure what to do next.

I recently had an issue when my car wouldnt start. When I took it into the shop they told me I had a parisidic draw on my battery. They unplugged it and the next day it read I had no draw on my battery. Now the car is starting to act up again. The mechanic told me I might have to get a new battery however it turns over I just have to hold the key in the starting position for nearly 3 times longer then I usually have to. Im curious if a new battery is neaded or if it could be an issue with my fuel injecters, air intake or my fuel pump. I just had a used engine put into the car and the battery is about 2 years old.

Any suggestions would be apreciated.

I had it tested and it passed or exceeded the tests. Walmart said it was a perfectly fine battery. However the test was done prior to taking it to the mechanic

About three months ago I began to have problems with my Taurus failing to restart after a recent shut down and I'm also beginning to get sudden stalls or near stalls. If the engine stalls, it fails to restart.

I have found that if I let the car sit at least 15 mins w/o an attempt to start, then it will usually fire right up w/o an issue. If it does fire w/n the first 15 mins then it just chugs at about 300-500 rpm for a few seconds and then dies.

Starting with the first occurrence, I had shut off the engine and tried to start again about ten mins later. It ran very rough, almost like when you pull the fuel pump fuse, except it ran longer, and then died. I tried to restart several more times (good crank but no fire) and then called for a tow. When the tow showed up the car started w/o an issue. A few days later a got an engine code. I don't recall the code but it went out on its own. Due to the mileage on the car I went ahead and replaced the plugs, wires, coil, PCV and cleaned the MAF sensor. A week later I got the same code; I'm thinking it was P1151, but it had something to do with possible fuel pressure issues. I was also getting some rough idling (around 700-800 rpm). The code has not reoccurred since replacing the fuel pressure regulator (I was getting minimum pressure readings). I also cleaned the IAC.

In total its failed to restart about ten times. I've also noticed some rough idling when at a stop. It will sometimes drop to about 700 rpm. A few days ago my son said the car almost stalled and the engine lost power (no response to the throttle) while he was driving. Then yesterday, it stalled on me at a light and again failed to restart, except for one short rough idle start. I let it set for an hour and it fired right up.

I've not had any engine codes other than the one related to fuel pressure and that last occurred two months ago. Yet, its failed to start after a short shut off at least four times and has stalled w/o a restart once since the last code.

I've read several comments about similar engine issues and about the MAF and IAC and how the PCV valve can cause issues with the IAC, but I think all is ok with these systems. I also cannot find any vacuum leaks. Last year, after a similar stall, I had a code that eventually lead to the EGR sensor and I found a hole in the crank case ventilation line as well.

I've read where some folks have experienced the anti-theft light when their Taurus' have died indicating a possible issue with the anti-theft system shutting off spark and fuel. I've not noticed this but I'm begining to wonder if it might be an issue. Unfortunately, we lost the other key 13 years ago and I do not have a second key to play with to see if the anti-theft might have an issue with the key.

The pressure tested on the low end two months ago so I replaced the fuel pressure regulator, the pressure was fine after that.

Its an easy test so i'll try and find atest kit with a ford adapter - the last three I've rented were missing the schrader valve part

Hi the proublem i'm having with my car is it will not start when I turn the key it makes no clicking noise or anything and my directionals dont work but if I run a wire from my fuse box under the hood to the fuse box in the car I can then go back under the hood and start it through the starter relay I hope you can understand what i'm saying and thank you for your time

I have a 1999 ford taurus se when I turn the key it wont start the heater won't come on the turn signals don't work but the radio works I checked the wires did find anything wrong with them fuses are all good I thought it might be the computer that sits in the right side firewall might be bad but it's not was hoping you could give me a clue sorry to bother you again i'm just not sure what else to look for so if you could please help me out I would grateful thank you very much.

Thank you very much. I was wondering if you could help me out on another question I have a 95 rodeo when I go down the road in it. It spits and sputters I changed 3 feul injectors and I changed the map censor twice the reason I changed it twice I thought I might have got a defective one the first time. When you go down the road it just looses power. If you could give me a clue on that I would greatly app. It thank you.
