1987 Mazda RX7 Car Cranks but wont start has fuel injection
1987 Mazda RX7 4 cyl Two Wheel Drive Manual 147000 miles
Hi I have a 87 mazda Rx7 it was running but now will crank but wont start any help would be appreciated thank you.
Cranks but no start condition: Rotary Engine
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, 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.
