Mazda RX7 GXL 1990 starting/stalling problem
Hi. I am new to this site and registered years ago now finally need help from a knowledgable user with the same year and make car I have. I am the only owner and rarely have driven the car after the first few years that I put on a few 10ks each year, but always warmed it up through the year and took a mile or two drive. I know have 33k miles on it. It was regularly services during the first 5 years by Mazda dealerships. Never had a single problem with the car. This past winter I did NOT warm it up enough and the last few times I started it up several months ago it put out a little white smoke and then it cleared up. It got to a point where when I drove it it wanted to stall out and finally got to a point where I had to rev it so hard to keep it from stalling. Then it got to a point where it would not turn over. Cranks like new but will not turn over. Gas was down to a few gallons thank God so I asked around what to do. I used some STP additive to take out any water and clean any corrosion etc. still cranked, but did not turn over. The I was told Seafoam may do the trick. I used 8 ounces in the few gallons left in the tank and that almost made it start but it did not. Then I changed the 4 spark plugs using the correct original plugs and that did not start it. Then I figured I would get someone to change the fuel filter and I got the OE and we did that, primed it, still cranked beautifully and did not start up. Now I am clueless and I need help from someone. I do NOT know my car well and cars in general that well so if you can speak to me like a layman that would help. WHAT DO I DO NEXT? I can do a lot so if you use layman terms I can do anything! I am great with my hands and had no problem changing spark plugs and the gas filter that a friend helped me with. I even found a link regarding the CPU and ran a line from the little green single outlet plugon ear the battery and grounded it and looked for any codes and on my panel no codes ever came up so I am capable if someone is knowledgeable to help me troubleshoot. I read so much on the net but have no idea what to do next. I am David and you can always email me at Bartharlowi AT yahoo.com I feel that the fuel sitting is all that could have gone wrong, but why is it that with a new clean fuel filter it still is not starting. The person that helped put in the fuel filter confirmed he hears the fuel pump working. I put in another gallon of 93 octane V Power Shell gas yesetrday and it started! White smoke poured out that it was amazing for 5 minutes! BUT i had to keep it reved at like 4000 rpms to keep it from stalling. Then finally when i let it doen to 3000 rpms it stalled and I could not get it started again. I then got another gallon of Shell V Power 93 Octane gas the next day and put it in the tank! It started and so much white smoke I could no see! I kept it reved at around 4000 rpms until the smoke was cleared then the tach meter went down pretty fast and it stalled. Got it started again, took longer, and same stall out. Then when I continued to try to get it started again it just would not turn over and was straining to start and a hear a few grinds like metal on metal when it almost started and then I stopped. I noticed this time some smoke crom the gas filter and it smelled like burning oil! I had the same oil and filter in there for 6 years now and it still is clean because it was driven maybe 200 miles in the 6 years! What is wrong with my poor RX7? Someone help? Is it a sensor of some sort and if so what and where is it under the hood and what do I do to trouble shoot? Thanks for helping someone out there.
