The engine of my 86 ramcharger ( 318 ) rotates but does not start. We have replaced the Voltage regulator, start relay, horn relay, pick-up, and rotor. But still wont start
have the same problem?

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
If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing

There is no spark, so I think im going to get the coil's checked. Its a carb'ed engine and a mechanical fuel pump. Its not a fuel problem because we have poured gas in the carb and starting fluid. And no fire what so ever.
