My car suddenly won't start. I have power, air and fuel. It cranks but won't catch. Is it possible it could me the fuel filter? I hear the pump go on but the car won't start. Any suggestions? Also, if you think it could be the filter, where is that located?
Is the security light on? If the security light is on sometimes it won't allow you to turn your car on. That is what my Pontiac did. I had to turn my key to the on position but not all the way. I had to leave it there for 10 minutes. Then turn the key back to the off position then start it. The security setting will then allow the car to start.

This sounds strange to happen after a service is done on another area of the vehicle. I would look at damage done by the hoist mechanism.
The hoists have lifting arms which meet the frame of your car. You have wires for the O2 sensors which can hang low. The fuel lines follow the frame and possibly could be crushed.
Vibrations. Air wrenches make vibrations which theoretically could shatter delicate electronic components. If you have sediment in the tank, this is also a concern, Some Ford products use a tank filter which can disinegrate and clog the fuel pump.
Get a pressure reading from the test port of the fuel rail. It will tell you if the problem is there.
You basically had a intermittent problem,If anything it probably was not the fuel pump, In order for the fuel pump to turn on the ECM, needs to see a crank value, of 250 RPM or the fuel pump will not turn on, what gives this it is the crank sensor,The crank sensor does age and when it goes out you can be driving down the freeway and all of a sudden the car stalls,and it doesnt start up,
It can take several minutes' worth of cranking to get the air out of the system before the pressure builds to the pojnt that the car will start. I assume that the engine's cranking, but it just won't catch and run; you can bleed the air out of the lines faster if you take the dust cap off of the fuel pressure test connector (it's right behind the power steering fluid reservoir) and GENTLY push down on the valve. I wouldn't do this while cranking the engine, as you can get a huge spray of fuel in your face and create a really serious fire hazard that way, but several cycles of briefly turning the ignition on and off to run the pump a little and then letting the air out will generally get the system to the point where you can start the car.
Well then if no pressure at fuel rail then go to pump and in line filter as the in line filter might be the main problem but the pump pressure can also be faulty if filter is bad so check it out and let me know how you get on. Ron
yep i seen it in happen .i was at a gas station a guy drove car to the gas station on empty.he fill his tank up .could not get it to crank .some cars you have to restart fuel pump when run out of gas. like chrysler.you use a scanner. but chervrolet you run low over heat damage the pump.it has to stay submerge gas to keep it cool. check fuel pump pressure.it should be 41 - 47 psi.
