Engine Mechanical problem
1995 Mazda MX3 4 cyl

So my friend has been working on my poor car for a month now but he still hasent fixed it. He changed the Head Gaskets, The timing belt, The water pump, and something else that I cant remember the name :p But the car still wouldnt start. So he replaced the cap and the rotor but it still wont start. Any ideas of what it might be?

Pick your symptoms below check it and get back with some testing results.

**Cranks but no start condition:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 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 so, 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, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.

**No crank at all/nothing/nada when key is engage to starting position.

Could be a blown fusible link, the starter, starter relay, clutch switch/park and neutral switch/transmission position switch and ignition switch assuming the battery and connections are good. Note:If it doesn't apply disregard.
