A neighbor has an 86 Mazda RX7 (rotary) that will not start. Says it was running good. he parked it one night, and it hasn't started since. The fuel pump has good pressure, it has spark, and enough compression that it should run, 85 to 95 lbs. I haven't checked the fuel injectors, but It will not even fire, or backfire, when I put some gas or spray carb cleaner in the intake. I have never seen this before. They will usually at least backfire if the spark timing is off. I have very little experience with rotaries. Suggestions??

Did you check for spark on all plugs? Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Checked both rotors. It was about 3 weeks ago I worked on it---and now that I think about it, I may have only checked fire between the wire and plug. And I only checked at one primary plug. Also, i checked the fire before pulling all plugs to check the compression. Owner had put new plugs in it, and I assumed they were good. Now that I think about it, that was probably a mistake, and I may have just diagnoised my own problem. I remember being in a hurry when I worked on it.   Email This Post   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
