I have a 1993 chevy Z71 1/2 ton ext. cab 4x4. It started dying on me about 2 months ago in traffic. It started right back up, and didnt die on me again for about a week. It has started dying on me almost everyday since then, now is wont start at all. I have replaced the fuel filter,M.A.P. sensor, Injectors, Air cleaner just last week.I thought I fixed it, it ran great. It died twice today. Its in my drive way and wont start at all. I replace the fuel pump about 2 years ago also.
This is my everyday driver, what should I do now?
Thanks for any help.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, 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- Note: If it doesn't apply disregard it
