The other day I went to go to work, running late, started my 89 74k mile vert. I realized that I had moved my license plates around and didn't have time to put them on, so I shut it off and jumped into my new Evo (woohoo!, but another story).



So, I go to start the RX today...no go. It turns over, but won't start.



Do you think its possible that I have blown the motor on a carbon desposit. Seems like it turns over a little too quickly. Does the carbon deposit problem typically lock the engine up, or have you guys seen it blow the seals and keep free?



Any help is appreciated...thanks!

i blew a seal on the rear rotor and the car would start with a lot of gas just run real rough.

it sounds like your car is flooded.

if you do a cold start and it runs for just a few seconds it can flood out before all the extra fuel gets burnt off.

look up the flooding thread in the F.A.Q section.

happened to me a couple times

IF its flooded:



when you go home go buy new spark plugs....then unplug the EGI fuse...take out the leading spark plugs.....crank the engine for 10 seconds.....let it sit for a few...then once more for 10 seconds



install egi fuse, install new plugs....start car

FrestyleFC3S.....



Why do you suggest the new plugs and taking out the leading plugs to unflood?



Up until my rebuild, I had a lot of flooding problems and I would take out the EGI fuse, crank it over, re-install and it would start right up. No plug removal or nothing. This was with both clean and dirty plugs. Mine is an 87 GXL (S4).



I also thought that an 89 could be unflooded just by flooring the accelerator. I guess I am wrong.
