Ok, I just got a 89 rx-7 vert that had been sitting for awhile. I changed all the fluids and charged the battery. It turns over fine but it will not fire. Can anyone help me out with this. I have own my 95 3000GT for 5 years now but I have no clue about the rx-7. I was just given it last week. It has about 90K on it right now. Anything will help! Thanks!

Gasoline can crystalize over time. Is it getting fuel?

thats true I will have to check to see if its getting fuel! I guess I should just emty the tank? Thanks!



JM

yes empty tank and refill with some good shite, check what condition spark plugs are in, if they are all old and crusty think about replacing them. but if they smell like gas, unplug the fuel pump in the back and crank with gas pedal to the floor until it unfloods. then plug in and try to start again.

I have an 86' GXL that sat for 3 years until it was junked and I recovered it, so I feel your pain.



Check the basics air, fuel, and spark first.



Drain the gas, and run Marvels Mystery Oil in your new gasoline very heavy, 1.5 ounces to a gallon. You will smoke a little but it will help. Also you may need to have another battery charging and waiting becasue I went through a couple trying to start mine. Have some one listen or you listen to the engine while your trying to start it. Rattling and clunking = bad of course. If it sounds like it is turning over too fast like there is no resistance, you may have little or no compression. Try the Automatic Transmission Fluid trick. If it gets to that point we can walk you through it. Good luck...

NO! **** the atf! atf is teh whack.

plugs, wires, gas, battery, coolant, oil. do all these things before you even try and start the car.

OK. i was in the sam spot. you have to put new gas in it. then put about a tbs of oil in the rotor housing and let it sit for a day or two. if that does not work do the same with atf. but with the atf you WILL need new plugs. also try a tune up some times that will fix it.

see your car is not starting because no iol has gottin to the seils in a long time so you are not getting the compretion you need.

but you want to check for fuil spark and all that.

also look at eveythink to see if it all looks too be good and where it all should be if you see somethink that looks funky then right back and somone will help you.

One of the most frequently over looked simple maintence items when starting a car that has sat for an extended period is the fuel filter. Sure it make sense to drain old gooey gas from the tank. But the same crud has caked the fuel filter and will block or at least slow gas flow. Go to Mazda and get an OEM filter and replace before you start her up.

Thanks guys for all of the reply's!! I finally had a day off so I got the chance to work on my cars. Everything you guys said helped me out! I had to drain the fuel tank and then put some back in. Then I changed out the fuel filter. It still would not fire! So I thought I would pull the fuel pump out and check if it was working right, which it was not. I got a new one for $99 at NAPA. I replaced it and tried it again. It finally started to fire a little! So I charged the battery up again and waited till tonight to try it again. It started right up!



The idle was very high around 1500-2000 then it droped down. It was running good for about 5-10 mins then it started to lower in idle and started to die.



Now what might not be good, white smoke started to come out of the exhaust. It had a strang smell also. What could this be? Seals?



Anyways when it started to do that I thought I should turn it off and tell you guys.



I know it has sat for like 2 years but it was running fine and then came the smoke.



The engine was running very smoth and quiet at first.



thanks

OK, sorry I just saw a post that said it could be a coolant problem. Is this true and if so what do I need to do to fix it? Thanks!



JM

If a coolant seal is bad, the only way I have heard to fix it is to tear down the motor and replace the orings. If it isnt too bad it may still be driveable. I have been driving mine with a small leak for 6 months though I am planning on rebuilding the motor this summer.

get a coolant pressure system tester, if it holds pressure then you are all good, if not then it's your water seal or a leak somewhere. it's really the only way to see if your seals are working properly. otherwise you could have different problems going on.

I had 2 shops pressure test my engine and tell me it was fine. They however couldnt explain why I kept boiling over coolant. A rotary specialist shop finally chemically tested the coolant and told me im forcing combustion gasses into the coolant. Is there anything special you have to do when pressure testing a rotary?
