I just picked up a 1989 gtus with jdm turbo II swap, the swap was only done 500 miles ago and almost everything on the car is brand new, According to the previous owner it ran fine before just a little rich he said. We tried to start it and it cranks but wont turn over. He said it may just need fresh gas and some plugs...Im new to rotary's and wanted to get your advice on what the issue may be. ive included a list of the mods below, Please let me know your opinions. Thanks!

Is this a car you are buying just for something to mess around with and you DON'T need to actually get around with? Is this something you can chip away at while you daily drive something else?

Honestly, run away. It could be a simple issue, it could be 10 different things. "If I knew then what I knew now..."

 

Try putting a teaspoon of oil in each rotor chamber via the sparkplug hole. See if that helps creat compression.

Could be a number of things though....Does it have spark? What about fuel delivery?

 

I have a daily driver, but my plan is to eventually phase that out and rive this for a while, I mean the engine is basically new so how serious could this be?

 

+1

usually engines that have sat for a period of time have sticky seals.

 

What do you mean by sticky seals?? I havent had a chance to investigate if it has spark or fuel but its almost turns over, its like it wants to but somethings just holding it back. Im off thursday so I plan on trying whatever advice I get here.

 

What Karack means is the seals won't create enough compression to start. Esp after its been sitting awhile. If you was flooded the last time it was started or that fact that your cranking it now means theres fuel in the chambers. Lubing the internals with a teaspoon of oil will do no harm and also lube the internals.

 

well, it does cause a smokescreen and possible fire dept. called.

 

TRUE. OP take caution if you live in an area where this is a no no.

 

I will do this, do u think putting fresh gas would be a good idea? Or should I just try this first?

 

drain the tank and put in new gas and plugs. put some oil in the plug holes and spin it over a few times then try and start it.

pray you have compression.

 

UPDATE!! I got it started, It started rough then smoothed out and ran great, I even took it a drive...Man this thing hauls. I have a 2004 clk55 amg and it felt faster than that. I got back turned it off and tried to start it 15 min later it it wouldnt start...Granted ive done nothing not even changed th gas thats 1 year old. I plan on doing some stuff tomorrow, Whaty do you think the reason would be for it not wanting to restart??

 

congrats!!!

it most likely flooded on you. it will do that for awhile untill the seals break back in. do you know how to de-flood? full the fuel inj. fuse by the battery then start the car with the gas pedal down for 10 sec then another 10 sec then put the fuse back in and she should fire up.

yeah 500 miles on the rebuild? def needs a good break in. you need to put a lot of miles on it before it will stop flooding. at least another 500

 

Thanks, Im super happy! Its actually not a rebuild, Its a JDM motor that had 30000 miles when it was swapped in, and the previous owner said he probably only put about 500 miles since the swap....but from what ive read on here even swaps need time to build compression. I figure the old gas and oil could be contributing too, so I will change that as well. when you say another 10 sec, do you mean with the pedal up?

great site loads of info

 

change the gas before beating on it again, octane rating deteriorates over time. you could have in fact blown up the motor by driving the **** out of it with 1+ year old fuel which could be why it is not restarting.

this should be a no brainer for any force inducted car owner.

 

So I got as much of the bad gas out as I could and put some fresh gas, also topped off the coolant and checked the oil, everything looked good, Tried to get the plugs out but need a bigger socket, going later.....So I try to crank it over a couple times and its not starting so I stop.Then I look under the car and see a small puddle and investigate it, smells like fuel and water but hard to say..now Im lost and a little worried. It ran fine yesterday and was only on for about 10 minutes. Any Ideas? did I over flood it, or is that even possible??

 

you'll simply have to trace it back to the source and figure out where the leak is coming from, hoping it's just a simple fuel leak.

 

Check pulsation dampner. Although s5's are all metal yours may have the plastic end.

So you never put oil in the engine through the sparkplug holes? How decent are the plugs?

 

if you want to drain all the bad fuel out you can pull the feed line off on the drivers side of the firewall, jump the pump and pump it into a jug etc.

Was this just an S5 thing? Or s4 thing?

 

[QUOTE=rx7_FREAKKK;10819124]s4 has the pulsation dampner with a plastic end. May become brittle and break or loosen up and leak fuel.

s5 is all metal and is a better design not to leak.
