you can write it out and I can answer what i can and he can review if you want. not sure how long it will take didn't expect such a quick response. thanks
Expert:  AMEDEE replied 6 months ago.

NO problem.

Have spark and fuel been checked?

Customer: replied 6 months ago.
Spark plugs were checked and they suggest we replace coils but they do not think that is it. As for fuel no we did not but he has filled up since it started
Expert:  AMEDEE replied 6 months ago.

Ok, it could simply just be a bad fuel pump. This is very common. I would check fuel pressure next.

Or another thing you can do is check to see if the engine runs on starting fluid. If so, you know it has spark and compression.

Customer: replied 6 months ago.
ok i will tell him is there anything else possibly? Does the Theft light mean anything? Even though it is off now
Customer: replied 6 months ago.
we replaced fuel filter not pump
Expert:  AMEDEE replied 6 months ago.

YES, if the anti theft light is on or flashing, this could be a bad PATS transiever or a faulty ignition key.

Another possible cause would be a faulty PCM, blown fuse, wiring issue or even crankshaft position sensor.

would the Theft light go out
Expert:  AMEDEE replied 6 months ago.

If the problem is related to the theft system, the light will be flashing..

Customer: replied 6 months ago.
the theft light flashed after we replace fuel filter than when out and has not come back on
Expert:  AMEDEE replied 6 months ago.

Ok, then no, the no start condition is NOT related to the theft system.

Customer: replied 6 months ago.
ok well we will look again. Thanks for your help and I will pass to my husband
