Ok i bought a 1988 Rx - 7 vert from a lady, no problem with this car. But she has another one a red one with 65,000 miles same year, all stock.

She drove it to the gas station and then back home less than 1/2 mile. Ran perfect no problems, when she got up in the morning, it wouldnt start. So she calls me, I go over there and look at it, and sounds like its not getting any compression. You know the sound it makes (like its turning but there no puffing sound?/if that doesnt sound too weird)...

Well I check the spark plug wires with a timing light wire cranking shes firing. And I smell gas so its getting fuel...Smells like its flooded. So i pull the EGI fuse and crank it over several seconds to clear out the fuel a little, then retry with the fuse in. Didnt help.

Think shes carbon locked? I had a 1985 and an 80 that did that **** all the time... Think drop a little ATF or oil in the leading plug holes and try it? What you guys think?

Just something to try....

Disconnect the fuel pump relay while someone tries to start it, when it sounds like its going to start plug her back in and have that person hold the pedal to the floor the whole time.

let me know if it works.

Were is that plug at in a vert, in the trunk?

Why cant I just pull the relay under the dash? I know where it is...

anyone?

if she drove it less than a half of a mile, she's probably flooded. try push starting the car and dropping the clutch. that's what I always do when mine floods

works like a charm.

Try this (I'm not sure if it works with NAs, I assume so):

1) Pull EGI INJ fuse in engine bay, near the battery

2) Try starting (should sound strong, but not fire)

3) Replug EGI INJ fuse and try starting like normal.....

Should start right up

take out relay, remove spark plugs, hold pedal to the floor while cranking the engine until there is no more fuel vapor coming out the spark plug holes, clean and dry spark plugs and put them back in. it should start.

Well she just towed the car over here to my garage tonite, so Im gonna tear into it tommorow. But its just the way it sounds when it cranks. If anyone has ever heard a rotary with no compression crank you'll know what I mean. My 85 and my 80 both used to do that **** all the time in a severe temperature change (its been like 70 or so and then 30 or so at nite and then cold as hell in the day and then cold at nite plus really rainy/our weather is TOTALLY screwed)

First thing im gonna do is pull the leading plugs, one at a time, and crank her over and see if it has compression. If not Im gonna add a few little squirts of ATF or Oil on each side of the rotor, clean the plugs and crank her again. Usually it gives it enough compression to start and then breaks the apexes loose. After that its gonna get a real good driving, I know she probally shifts this thing less than 3k each time

Just thought maybe someone here had seen this happen all the time. I know it was quite a regular thing with a 12A, but seems like 13B and the EFI like to flood really bad... Thanx guys...

Mike,

Before going to all that trouble, why dont you either push/pull start her(tow around the block) or use my method of atf injection which is alot quicker. ON top/front of the manifold are 3 vacuum hoses. Remove the top, largest hose, and use a hand oil pump to shoot atf down this hose. This leads directly to each rotor housing. Helluva lot quicker and easier than fooling with plugs. Even if its BADLY flooded, this will start her right up. Let it sit for a minute then try to crank it. Id just roll it down a big hill if it were me.

as with any seal if there is too much lubrication (like oil or oil/gas) the seal can actually ride on top of the lubricating material (oil/ gas mixture) just like a car hydroplanes on top of water. that is why in piston engines they have what is known as an oil control ring that removes excess oil from the cylinder walls before the piston rings come down. the rotary can sound like it does not have compression because of the excess gas and oil which is causing the apex seal to hydroplane and not seal well. it (low compression) can also be caused by a stuck apex seal due to carbon build-up which can be somewhat remedied by the use of atf. good luck. i have experienced this problem in my 1st gen. rx-7s.
