Its a 1987 mazda rx7 gs auto wit bout 150k and has sat for a year..... did a full tune up, plugs & wires, air filter wit a shot of starter fluid, new fuel pump and filter, oil change, new battery and alternator tested, gas ... i sphyned it out and replaced wit new gas 3/4 tank with a bottle of heat included.......... ne idea's ???? its so close i can feel it ...........

 

You didn't really say what the problem is...

 

you gotta explain more, is it cranking?

 

I'm gonna assume it's not starting... Do a compression test- i got my tII and went through all of those same exact things- then i found out i had 0psi in the rear rotor ...

 

i try to start it and it turns over but doesnt catch, or start....like the engine turns over but wont stay started after turnin the key ...... i also replaced the starter

 

like the fuel pressure ????

 

Do you have:
1. compression
2. spark
3. fuel
4. air flow
5. EVERYTHING hooked up

 

i know the pumps good cause i got hosed down wit gas cause i forgot to take the fuse out for the fuel pump,

 

start with #1, check for compression

 

Try again with the starter fluid, and see if it starts momentarily. You didn't say anything about your injectors, but they could be gummed up.

 

if it sat that long you might want to put some oil in the chambers to help seal the apex seals

 

make sure everything is hooked up, especially your mass air flow sensor, and everything else on the intake...

 

unflood?

 

most likely its flooded

 

Look at the front of your dynamic chamber. See the three *vacuum* lines one above the other????

The large one leads straight to the oil injectors air feed. If you inject oil into that line, all four oil injectors will feed oil to their respective areas i.e. the rotor housings and the manifold.

The idea is to get oil into the rotor area and this seems to be a good way to do it. This is not an original idea. It's been done before. So get a squirt can and inject oil into that large hose and spin the engine over while you do it....with the starter. How much? Got me. I'd say three or four ounces or so.

With a little ingenuity you could rig container with an hose in it to that large hose I talk about and it should siphon in the rotor housings as you crank the engine.

The idea is that your rotors/housings have had all the oil wiped off and you need to add some oil to get the compression back up so it'll start.

Just in case: It's the HOSE that you want to put oil into NOT the large nipple on the dynamic chamber. The HOSE is the one that SUCKS.

 

Mine did that I replaced the fual pump and vroom vroom. Good luck.

 

its Iceblue all over again.........

youreallyneedtocheckthecompresionbeforeyouputmuchi ntothecar.

 

im sure it's flooded.

this is a SAVIOR.

try that im more than sure it will start if u build ur compression with the ATF.

 

just take out the two trailing plugas and kill the power to the fuel pump, ty starting over and listen for all sides of the rotor, it'll be loud (if its good) and have a steady rythm.... worth the time, and did i mention its free? best way ive found to see if there is ANY compression.

 

so take out the bottom plugs and pull the fuse, then turn over to see if there is compression........ i unflodded the engine with no problem, but when i turn it over it started for about 2-4 seconds and died out.......... but when i pulled the fuse for the fuel pump and turn the key to aux. b4 turn the rest of the way, i heard the rythm sound to talk of, does that mean there is compression or not ????
