Engine cranks excessivly before starting in cold weather. Starts good in warm climate. No trouble codes detected. This has happened for 3 years straight. Doesnt start in Winter but fine for the rest of the year. I live in Atlanta so its only 3 months of below 40 degree temp outside.
Do you
have the same problem?

Check the coolant temperature sensor, clean the idle air control valve and MAF sensor -also do a fuel pressure test. This guide will help us fix it

Cranks, will not start. Checked fuel pressure-48PSI; power to all COP's and injectors; Checked all fuses-ok!Sometimes it sounds like it wants to start. Originally, while running, it was misfiring and Check Engine Light was on; Pulled Code p0301 (misfire on #1); cleared code. Started vehicle again and ran fine; next day went to start vehicle- cranked but wouldn't start (no trouble codes set in memory). Checked power to Fuel pump-ok! Checked power at Crankshaft Position Sensor- could not get power (may have been ground I was using). Tried starting with Starting Fluid- would not kick in the least) I don't think this is a mechanical problem. Where do I start, and what diagnostic procedure should I use to ascertain problem?

This sounds like the crankshaft angle sensor has gone out, but t be sure let go over this guide

https://www.2carpros.com/articles/car-cranks-but-wont-start

Please run down this guide and report back. Ok I need you to check to see if there is any spark to the spark plugs. Pull a spark plug wire and put a screw driver in the end of it and rest it near metal (like valve cover) and crank it and see if there is any spark.

If not then we need to test the crank and or cam sensor. Get back to me with what you find and what you would like to do.

Checked spark at coil-no spark; where do I check for voltages at the crankshaft/camshaft sensor sensor? I have both a digital multimeter and just purchased POWER PROBE II - LEAD SET COMBO KIT

Ok I would like to test the coil or coils first then go to the cam and crank sensors. So I need to know if you have a coil pack that all the plug wires go to or if you have an individual coil for each cylinder. Get back to me and we will go from there.

Racefan966:
Coils are COP
I attached a remote start to starter and turned the key on; I lifted the vehicle and was about to test imput/output voltage at the Crankshaft Positioning Sensor. The wires were protected in corrugated tubing, so I unplugged the connector from the CPS, exposed some of each of the two wires, and plugged back in. I hit the remote starter, and the vehicle started. I shut the vehicle off, unplugged the connector, applied dielectric grease, and plugged the connector back in- turned the key, and it started right up. I believe that our locale (salt air environment-Cape Cod, MA) and the fact that the vehicle is a limo and has 189,000 miles) led to pigtail connector corrosion, as the sensor is located in the front bottom of engine.
Thanks for your help!

Hello,

This could be a problem with your vehicle's Crankshaft Position Sensor[CKP]. In the diagrams down below I have included the Power-train Management wiring diagrams for your vehicle with the CKP wires high lighted for you, the location of the CKP, and the Original Equipment Manufacturer[OEM] part number of the CKP for reference as well. Here is a generic guide explaining how to replace a CKP below:

https://www.2carpros.com/articles/crankshaft-angle-sensor-replacement

Please replace the CKP and report back with how everything turns out.

Thanks,
Alex

I have a 2002 Town Car that will not start. The engine cranks like normal, battery power is strong, fuel gauge shows full, it just keeps turning over but does not start. There are no warning lights or other symptoms. There has not been any recent maintenance to the battery or anything else. The car was running fine the day before.

I have tried another ignition key which did not help. It doesn t seem like it is getting fuel so I checked the fuel pump reset switch which was okay. I also checked the fuel pump fuse. Can I get some suggestions on what this could be? If this sounds like a bad fuel pump is there a way for me to test that?

I thought gas line might be frozen, because it did not have a full tank of gas, put heater under it for hours moving from front to back, nothing. It has been running perfect, tried several times, strong crank so battery is good just will not start. Please help

We have a lot of these problems in the winter time and it is usually the engine coolant temperature sensor which can be off. This condition will not trigger a check engine light.

Here is a guide to help you see what you are in for when doing the job:

Here is what it will be like for your car (below).

Please let us know what happens.

Changed cam and crank sensors, checked connections everywhere including starter ground and transmission wires. Sprayed starter fluid in still crank no start and it didn't sputter like the starter fluid made no difference. Thought it might be a bad ground so I ran jumper cables from the negative terminal to the alternator, still cranking but won't start. Any ideas?

Have you done a computer scan to see if there are any codes stored? Here is a link to help you scan for codes if you have an OBD2 reader.

Here is another link you can review for not running:

https://www.2carpros.com/articles/car-cranks-but-wont-start

I also think you need to be checking to see if you have spark? But the computer scan should be the first thing you do to see if any codes are stored that will give a hint to what is going.

Thanks for responding so quickly. I haven't ran a scan because I don't have a reader. The car is in my driveway and the closest auto store that will scan is five miles away. Do you think the ignition control module ( in the steering column) would cause a crank no start?
