My engine cranks but wont start?

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?

Getting back to you regarding our dialog of Feb 16th-just pushed it back in- will check spark at coil output and forward results

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

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!

Took my car to car wash and I pressure washed under the hood at the car wash. Drove car home ran great. Next day go to start car cranks over but does not start. The fuel switch in the back trunk has been reset. You can hear fuel pump kick on still won’t start. I’ve checked all fuses no issues looked for access water on all components all good. Please I am needing some help.

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 had this problem and had to replace the sensor fired right up cost me $56.00 for the sensor.

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

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?

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?

So I got a computer it says error can not communicate I one bye one upluged every single connection and ran the scan still can't communicate. Any ideas?
