just bought a 86 with a 13b from a friend. he sold it to me not runin and said there was water in the gas so i went out bought a new fuel pump cleaned the tank (and there was maybe a 1/8 inch of gas in the tank but was rusty lookin .
so cleaned the tank repleced the pump and turned it over well it sounds like it wants to start and seems like its trying but just not turnin over. oh and he did say it was sittin for about 3 mounths.. maybe injectors bad?? did flush em out and was some white gas that came out lol ..

any advice would be appreciated ...

wait, so it'll turn when ignition is applied, but it's not starting, right? replace spark plugs would be my first suggestion, then test the rotors for compression

HopSinga

well previous owner replced plugs wires and the terms. it has spark already checked for that and i can hear that it gots some compression fromt he exhaust but im not sure how else to check iif the rotors have compression?

BklynRX7

definitely try a compression test here:

will most defintly try that ill let ya know what happens is there anything else i should look out for? and also need a little help finding the timing lol only looked for it once yesterday but it was at night and only for a second is it on the bottom of the housing? or up top?

whoops, missed step 10: hook up a timing light to the L-1 high tension lead.

it's probably flooded

i let it sit for a day and still didnt want to start and were do i get a timing light??

HopSinga

also is there anyone that can send a pic or illist. of were timing is located ive checked and it its the right one i dont have and colored marks lol engine bay is clean to no grim to hide anything??...

Thats what I'm thinking also. Try to unflood the engine before you do anything else. Basically, you pull the EGI fuse, crank the engine for a bit with the pedal floored, then replace the EGI fuse to try to start it. Repeat of necessary. Also remove the leading plus and dry them off if they are wet with gas. As a last ditch effort you can put some ATF in the spark plug holes to try to build compression. Since its been sitting a while, you might need to do that.

i know im a noob lol with these but im glade i decided to get an fc for a started car but sorry to ask wich if the egi fuse? i got 3 fuses under there that are 75s? one of them of is it a round fuse or somethin? never had to change one or pull one out lol thnks. =)

It's the EGI IGN fuse, in the fuse box under the hood, on the driver's side, all the way on top (easy to see). The fuse cover should have the name of each fuse on it. If you don't have the fuse cover, then it's the 2nd one from the top, 40A. If it doesn't clear the first time, try again 2-3 more times. But give the starter some time to cool down between attempts.

You can get the timing light at any auto store. Download the FSM from the forum FAQ or get a Haynes manual to see which spark plug wire to clamp the timing light around. I forget which one it is. Plus either manual will give the whole procedure. The spark plug wires are the 4 wires going to the spark plugs in the engine block from the coil packs near the driver's side fender. I'd get the Haynes manual anyway to handle all kinds of maintenance items. For diagnosis & repairs I find the forum is often a better source of info.

yea i mean i got a good bit of knowledge with piston engines but first rotary and first time workin on em and im kinda new with wiring and some technical . and i ordered a haynes manual yester (5-7) days and i think i agree so far i get almost any question asked awnsered on this forum glade i found it lol.. thnx btw.

Ok well unless you pull apart the engine most everything is the same.

Common RX-7 specific problems (do a forum search): OEM thermostat, fuel pulsation dampener, DTSS, oil cooler lines, logicon, wiper switch, 5th and 6th ports aka auxillary ports (if upgrading/removing the catalytic converter), 3800 rpm hesitation and/or grounding (see www.aaroncake.net for a guide) and flooding, heh. Also rotaries are extra sensitive to overheats or running with an empty oil sump. Pull over in less than a minute if the temp needle gets to 7/8 (though 1/4 is ideal) or if oil pressure drops to zero. Naturally this is all on top of basic maintenance, especially for the cooling and oil systems.

lol well i went out and bought some started fluid tried that and still didnt fire. um i mean the sound from the engine just sounds like the starter is spinning and not grabbing anything but the engine is turning over i can feel it from the exhaust but its hard to discrib one of those things kinda gata be there for i could make a vid on cell and post that but im not sure wat to do..

well when i first got the car i drained some oil out to see if there was water in the oil to see if it got in the engine but oil was good havnt replaced the oil yet but theres still at least 2quarts..
