So my car was running fine yesterday, park it in the garage, and today it wont start... engine turns... wtf?

 

nevermind, goit it started using egi trick,... is doing thatbad for the engine?

 

no

 

what is the egi trick?

 

Unflooding procedure. Pull the EGI fuse, crank the motor a couple times, put it back in basically.

 

EGI fuse is located where? I am having this same issue.

 

i prefer disconecting the fuel injectors via the resistor box on the passanger side

 

I am having the same problem, the engine is flooding.

It started fine this morning to move it, and then when i went to start it this afternoon it just cranked over. So i checked the spark plugs and changed em as they showed some carbon build up. That didn't solve the issue. So i pulled out the two EGI fuses located right in front of the driver wheel well ('86 GTU) in the black fuse box. Turned the engine over a few times. Put fuses back. It still won't start, and smells horribly of raw fuel.

I am going to go back out and test the plug wires for voltages and resistances.

anything else I should look at/check??

 

yea my car does the same thing, luckily i have a fuel cutoff switch. it works great, but i'd ultimately like to fix the problem. :\

any ideas to help our flooding?

 

I went back out, checked the plug wires, all ok. So i just unplugged the harness for the fuel injectors, and cranked the engine a few times. Plugged the fuel injector harness back in and then started cranking the engine. At first nothin, but I kept cranking, and it caught a few times. So i stopped, and started cranking again. It started catching more and more and finally started to run. I pumped the throttle to keep it running and it improved the longer it ran. And did it produce the biggest cloud of white smoke i've seen.

So what I concluded is that if you turn the engine over quite a few times trying to unflood it, it will buildup with extra oil. So you need to crank it longer.

Also, I learned that on the newer (95 and later) Fuel injected cars, if you hold down the throttle (100% open) when cranking the vehicle, that will signal the ECU to reduce fuel flow so it doesnt flood, which i tried on the rx7. It seemed to help.

So all in all, check your spark plugs, clean em if necessary to remove excess oil or buildup, change if necessary. Remove the EGI fuse and disconnect the fuel injector relay, crank the engine over (it may help at this point to leave the spark plugs out if you have them removed to inspect/clean them) to help remove the excess fuel. (reinstall spark plugs if you left them out) Reconnect plug wires making sure they have a solid connection (use dielectric grease to help conductivity and prevent dirt/water from getting inside the spark plug cap).

When trying to restart, hold the throttle down all the way and crank the engine, it may take a few tries of cranking before the engine will catch. BUt keep trying for a little bit as the excess oil needs to be burned off. And don't panic if you get a lot of white smoke once the vehicle starts. THis is just the excess oil. Its normal. After the engine does start you may need to pump/pulse the throttle to keep it running at first.

Any comments or corrections? I hope I have the info correct.
