Hey guys. Just curious about something. I've had this 92 Nissan Sentra on my property for two years. I've just about gave up on. Mainly because it was not my car. Long story.
The engine will run on starter fluid if I spray it into the brake booster hose and plug it off at the throttle body and will idle for three second then die.
Best I can remember from two years ago:
1) Engine ~ 90# to 100# of compression (220,000 miles on the motor)
2) Has spark
3) Has 40 lbs of fuel pressure
I cannot get the OBD I to flash any codes using the paper clip/check engine light method nor can I find any LED on the side of the ECU in order to start looking.
I initially thought perhaps the injectors were not firing (since it will run on starter fluid) but what's weird is if I remember, even after excessive cranking, the plugs were wet. So if it's getting fire and it's getting fuel then why won't it start? 90 lbs of compression too low?
My question is can a spark plug be too "fouled" to run on gasoline but will run on starting fluid (ether)?
I'm wondering if a petrol engine running off ether is like a diesel effect. Because ether is so volatile. Meaning it's the compression of the engine that ignites the ether and not the spark plugs themselves.
The reason I wonder sometimes I'll wet the plugs on my 2 stroker Trabant. Especially if I get overzealous with the manual choke or it's really cold outside. Hopefully the new battery cables will fix that this winter. If I give it a shot of ether, the car will start. So I'm thinking the same theory applies to carbon fouled plugs on this Nissan.
Maybe the first thing I should have done was changed the plugs. Or bead blasted the carbon off of them.
Of course once I get the engine running, now I have to figure out why the plugs fouled but since this car appears to have not had much maintenance, they could be just old plugs.
