2001 Mercury Grand Marquis Question: Engine cranks but car won't start

I changed my heater core on my car......put everythin back and now the car doesnt want to start. I also changed the fuel filter and pump but that didn't solve the problem either. -
Answer 1
Changing the heater core should not really impact a starting issue. However, since you have to pull the dash, if you did not reconnect something around the ignition area, it's possible something may be causing the problem here. I would recommend retracing your steps in how you removed and installed it, and check every connection. -
Comment 1
I have retraced my steps 3x I havent seen anything that I have missed. I didnt remove any wires from the ignition area. -
Comment 2
Next step would be to see what's missing - fuel, spark... -
Comment 3
Spark plugs were changed almost a year ago. Could they go out again that fast or woukd one with no spark cause it to not crank also -
Comment 4
Spark plug "failure" could not cause a no crank. Also, even if one plug did not spark, the other 7 would allow the engine to start. It's not the plugs causing your issue. Your question initially says "engine cranks but car won't start". Your last post was asking if plugs would cause it not to crank. I'm confused - is your vehicle cranking or not? -
Comment 5
Yes its cranking but not starting....i was just askin because people r given me different senirios -
Comment 6
What does your "THEFT" light in the instrument cluster do when it cranks? Stay on solid? Flash? -
Comment 7
I found out the problem. The wire was bad that ran to the fuel pump....... Now my fuel gauge is showing full but its only 4 gallons of gas in my tank -
Comment 8
Nice... If the gauge is "full" it means that the wire is probably open somewhere. Good luck. -

The engine cranks fine but will not start. Could this be a fuel pump failure? The car is clean and well maintained. It has 120K miles.

So recently I bought a used car from a dealership outright. When I first bought it, there were some problems and they thought it was due to a dead battery which would have made a ton of sense. Abou...
