99 Mercury Tracer won't start?

Won't start is it cranking over and will not start or hard to start but runs-

Jumped time?

Did you replace the belt?

There is no way a timing belt is going to jump time without some other severe problem causing it and the belt should NEVER be re-used.

What is the fuel pressure? You're dealing with 2-experts here and you're still not agreeing with us-Do below and whatever you do don't comeback without any testing results-we need this information in order to continue

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if okay-check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

BTW don't teach us something that we have allready know for many years-teach us something that we don't know about compression, fuel and spark- problems were just trying to help you out-
