I won a 2000 Mazda B2500 truck and sometimes it will not start. I replaced coil packs, camshaft sensor, etc and still the problem appears every few days. When it happens I can often wait an hour and then it will start. I have noticed that when it happens I do NOT hear the fuel pump power up. How do I know if it s a fuel pump or some sort of sensor. Before I change fuel pump ( hard !) I want to eliminate other possible problems.
See allot of references to this problem Mazda/Ford Rangers on-line but NEVER a solution. Please help ! Thanks

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 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,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
