nooob help
 

Okay here's the deal I jst got a 87 rx7 with 180k miles that been parked for about a yr the guy told me it started to smoke and he jst parked it. My problem is now I'm trying to get it started I'm getting spark but no gas the fuel pump when out I'm using starter fuild jst to get it started but its not happening I'm getting compression .......any ideas?? Oh yea its a 13b na

Get a new fuel pump... Stop with the ether.

Ether (starting fluid) blows up... gasoline burns. Take a lighter and hold it infront of the can of ether and give it a squirt... That giant flame ball you shoot out thats what your putting in your engine. So stop it; your apex seals will thank you later. lol

Your injectors are positioned by Mazda R&D to start the car and deliver fuel properly when the fuel pump is working. Hence new fuel pump = running car.

Alrite lol I guess ima get a new fuel pump and try that

Great time to upgrade to a nice walbro 255 fuel pump :egrin:

For reals 100 buxs down the street

anyone gonna tell this guy to change his fuel filter?..fresh gas?..clean the fuel pump sock?
By the way,you are getting gas to the Pump.It sits in gas..it just isn't getting to the engine.!!

I supose I am assuming too much. There could be a rats nest in the gas tank, or he could be out of gas. :-P

Lol when I buy a fuel pump I plane on cleaning the tank and freash fuel filter ....

Make sure you do the rats nest delete mod... although thats more of an FB modification :lol:

Lol those damm rats....

Update......new fuel pump got the car started smokes like a bitch blows white smoke from the exhaust....any help?

Well at least she's running now 8-)

Sounds like an exhaust leak or a hella lean condition. Have you run a can of seafoam through the machine yet?

No not yet I jst got done running it for awhile not smoking as much jst idles around 2grand

Like you just named the symptoms that the bottle of seafoam reads it cures :-P

"clears up smoke... smooths rough idle" - Seafoam :nod:

Compression test it and stop spending money on extra things. at 180k, sitting around for a year or more, and tons of smoke whenever you start it, a compression test is the first thing i would do just to get it out of the way.

The first thing I would suspect is oil control ring seals. If nothing else clears the smoke that is what it is and it means the engine needs to be split apart. At 180K miles compression could still be high enough to make it run but a split O ring in an oil control ring spells doom. If you do split the engine expect 50% of the parts to be junk.

If you do decide to try a rebuild get a couple engines to tear apart first. Pick through the parts you have and find the best stuff, measure, measure, measure. Then yank the engine out of the car. If done on a budget you can throw one together for well under a grand.

yea i might try that my other buddy of mine told me to do that as well

i wanted to compression test my motor but i read somewhere that u need one jst for rotarys that its different from others

hmm well i wanna rebuild my motor if its bad but im having trouble finding parts or a rebuild kit ....... i was also thinking about buying a swap from a website but i dnt know any

You can use a basic piston tester and remove the schrader(sp?) valve, but you need a friend to crank the engine over and hold down the gas and you need to watch each bump, each rotor has 3 different compression readings.

I kind of jumped the gun saying compression test, it for sure is a good test to do, but may not diagnose your exact engine problems. Pressure testing the cooling system and testing it for exhaust gasses would be good things to test first.

Seafoam is a gift to any motor. I sell parts for a living and that is what I tell people getting a new to them vehicle, it will help a lot.

You guys are like super quick to say a motor needs rebuilding.

How does white smoke mean the engine needs rebuilding or has a loss of compression? Maybe if there was a hint of coolent in the exhaust... :scratch:

Coolant leaking into exhaust would also warrant a rebuild, so its not entirely THAT far of a jump to assume rebuild.

To OP- Atkins rotary, pineapple racing, rotary aviation all have, or should have, rebuild kits for purchase. If you crack the engine open, at the very least you will need a full soft seal kit. AT 180k it would be wise to replace apex seals as well. If you are on a budget, it might be cheaper to buy a running n/a engine off someone thays doing a swap or something.

If nothing else clears the smoke(try seafoam) then oil or coolant is getting into the combustion chamber. The smoke I spoke of is from the O rings inside the oil control rings on the side of the rotor(2 on each side of each rotor). We got a group of bad O rings a few years back. They lasted about 30 minutes of break in time before the engine started to smoke. We pulled the engine apart and it looked like the O rings had been perfectly cut with a razorblade in a couple places.

In an older engine the O rings can get hard and lose their sealing capacity, particularly if the engine has been sitting or if it has been run hot.

Anyone know any good az shops
