Working on this as a crank and no start, pulled plug and grounded it, no spark, went to end of fuel rail and pushed in the shrader valve, some fuel came out and stopped, while pushing in shrader valve turned key on, no fuel, cranked, no fuel, looked at the fuses at the drivers side near battery and find no burned fuses, believe it to be the ignition coil pack and believe that has module combined in it. Could this component control spark and fuel? Thanks for any help.
No spark and maybe no fuel on 1999 Ford Escort

Check the fuses. You need to take a look at the fuel and ignition systems separately. There's a fuel pump relay but the ignition module doesn't control the fuel system. There's an inertial fuel cutoff switch to check. You could have a problem in the ECM too. You need to state which engine it's got to help me out, makes a difference in the electrical diagrams. You have a shop, don't you? Why not look in a manual and check this out?

Sorry, it is a 2.0 liter engine "P". The fuses looked good at the box next to battery. I did not check fuses under the dash. Dumb, huh? I thought about the inertia switch after I sent post. Can you tell me where the fuel pump relay is located.It isn't part of the CCRM, Constant Control Relay Module, that was so famous for failure, is it? It is a manual trans, also. I have a garage at my house but no licensed shop that I work out of. I have not turned wrenches in a long time for money except for just the neighborhood, so that is why some of my skills are rusty. If need be I will get repair manual at parts store and make the owner pay for it. Thanks for your help. I really appreciate it.

raiderron, If you have power at the inertia switch while cranking the vehicle, the fuel pump relay is fine. A fuel pressure gauge is necessary to check fuel pressure. I have seen many technicians burned by assuming that there is no pressure by pushing on the schader valve. I have seen coil pack failures once in a while also. i hope this helps.
Plug not firing replaced it, checked all fuel lines, bypassed fuel purge valve and fuel canister. No oil in water or water in oil so head not cracked. Could it be a burnt valve or the valve seat.
The car seemed to be running on 3cylinders and then the check engine light came on.
