Engine not starting

Suspect starter.
Check and make sure all terminals clean and tight and if still have to tap on it to get the engine to crank you need to have it replaced.

Will not start. Put a different battery in, no change, not even lights or radio. I have been told it is not the alternator or starter if different battery made no difference. Is that correct? Please help! Thank you.

Check battery terminals.
If new battery and still no power and no light check fuses and battery terminals.

Initial symptom was the car would not start. No clicking at the starter was heard. Swapped several relays, still nothing. Found the battery positive cable disconnected at the starter. Connected and still did not start and would often not even turn over. Replaced ten year old battery, still same result but after a few more tries blew the 40 amp fuse (F1.07 Starter Relay/Ignition). Upon replacing fuse, still blows after two or three attempts to start. I have looked at a few wiring diagrams but still cannot determine what is in that path. Could it be the positive battery cable shorting or is it some place else.

I bought my car used, and ever since I have had it, it has intermittent problems with starting. Since I have had it the starter has been replaced twice, the relay was replaced, spark plugs replaced, wires replaced, and it has been checked for oil leaks (which it does not have problems with). Despite all of this it continues to have problems starting. Every three or four months the problem starts small. I will go to start the car and the dash board lights will turn on, but the engine will not turn over. It does not make any noises like it is trying to turn over, just the lights turn on and that is it. I will turn the key multiple times and it will finally start. In the beginning it will only take a couple of tries to start it but the longer I let the problem go the longer it takes to start and can end up taking hours to start. Like I said it has been in the shop multiple times for this and a grab bag of things have been changed. The strange thing is (and mind you I do not know anything about cars) I feel like it may be electrical because I have had issues with parking brake lights coming on for no reason, the interior dash lights not working for a couple of hours, the power windows not working some times. All of those problems will however correct themselves within a few hours to a couple of days. Please if you have any advice I would really appreciate it.

Remove battery terminals clean and tighten.
Also, should have the ignition switch inspected and or checked.

Two wheel drive.

I have been having a problem starting my car. It cranks fine but does not fire up. After a period of trying it eventually does start like there is nothing wrong.

I have a feeling it has something to do with the chip in my key. I started to use my spare set and so far I am no longer experiencing this problem.

Does the chip activate facites such as fuel pump etc.

I do not seem to be able to find much that is written on this subject.
Thanks for any information you can give me.

Principles of operation:
The PATS uses a specially encoded ignition key. This key is not compatible with previous vehicles or any current model year vehicles. Each PATS key contains a permanently installed electronic device called a transponder. Each transponder contains a unique encrypted identification code out of over 18 billion, billion combinations.
Each PATS key must be programmed into the powertrain control module (PCM) before it can be used to start the engine. There are special diagnostic repair procedures described must be carried out if a new PATS key is necessary.
This system contains a new feature named Unlimited Key Mode. This feature allows a customer to program more than eight keys to their vehicle if they request it. Each vehicle in Unlimited Key Mode is set up with a special Unlimited Transponder Security Key. This allows all the customer vehicles to share the same keys, but no other keys from outside can be used to operate the vehicles. For an individual customer, any randomly selected Security Key is acceptable. Refer to KEY PROGRAMMING-UNLIMITED KEY MODE.
The PATS transceiver module communicates with the PATS key. The module is located behind the steering wheel column shroud and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the PATS key identification code and sends data to the PCM.
The control functions are contained in the PCM. This module carries out all of the PATS functions, such as receiving the identification code from the PATS key and controlling the engine enable. The PCM initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
All elements of the PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
The PATS uses a visual theft indicator. The indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. The PATS system also flashes the theft indicator every two seconds at ignition OFF to act as a visual deterrent.
The PATS will be activated and will disable the vehicle from starting if there is:
incorrectly encoded ignition key (example Taurus/Sable key).
Damaged PATS key.
Unprogrammed key.
Non-encoded key (key has no electronics).
Damaged wiring.
Damaged transceiver.
Damaged PCM.

We have had problems starting this car when it has set for a few days. So we pluged a plug charger into the battery after every use and this seemed to work. We drove the car on Friday and when we came back to the embassy turned off the car at the check point and it would not start back up. I think the alternator maybe causing this problem but not sure. The car will not start at all now.

I got a call from our son the other day, "my car was sputtering and the idle was going up and down and then it shut off, now it will not re start". So I went and looked it over, trunk fuel switch not set, check, all fuses good, check. No spark on any of the three yellow wires at coil while turning over. Must be crank sensor, nope. Cam sensor changed, nope even put a new coil pack on, still nothing. The CEL is on when the ignition is on but will go off while cranking telling me the computer is picking up the crank and cam sensors. The initial scan result was "no EGR activity" forgot number but it was like p0401, but do not quote me on that. Any body have any ideas? Thanks, Gunner

Check fuses under hood and try resetting security system if no manual look online.

Would not start in moderately warm weather. After sitting for Three hours, it started okay but service engine light came on. Drove to mechanic (literally forty seconds down the road). Turned car off at garage and it would not start again after trying. Any ideas what the problem could be? Car has 99,000 miles on it. Thanks!

Check engine light on.

Have the computer scanned for code/s you have a problem within the engine management system that caused the CEL to turn on. This is your starting point of diagnosis, finding out what is going on.

Okay, diagnosis was vacuum hose from code. Eventually need a fuel pump. Sound right to you?

Fuel pump to confirm it, it needs fuel pressure testing with a gauge to rule it out. Do not be throwing parts at it. Get it troubleshoot to determine the caused and the defective item/component.

I just bought this SE model, 120,000 miles, but it was well taken care of, regular oil changes, etc.

In the past few days, I have had a problem with it starting at times. It always cranks, but sometimes it grinds for a minute before it will start. Do not think it is a battery, but might be the start of a starter or solenoid issue.

Not that this has anything to do with it, but it started just after going to a car wash. Grasping at straws here. It just started happening all of a sudden.

Any help or suggestions would be great!

You need to replace the starter, the starter overrunning clutch is slipping or bad drive pinion.

Before you replace it inspect the flywheel/flexplate ring gear for damages.

When I went to start my car after work, it did the grinding thing again and I did not think it would start. It did finally turn over and a small puff of white smoke came from under the hood. When I checked it out, it smelled of burnt plastic. The smoke came from the drivers side up near where the transmission fluid and brake fluid is added near where the ignition is, I would guess.

I took it to the shop to see what is wrong. The smoke was a little unexpected.
