strange issues and sad mistakes


Recommended Posts

so first off i should just say im new to both this forum and the subie world. ive only had the constellation on my grill for a few frustrating weeks and im already drooling over rallying videos and gold rims. of course my vehicle, a 1989 subaru RX, is from before all that and that is ok by me. 

anyways on to the real talk. i dont really know too much about working with cars or specifically with electronics. ive done some work on motorcycles and enjoyed it so im trying to do all the work i can by myself on my new subie. now there have been several mistakes made that have brought me to the point im at now, the first of which being i bought it out of an impound lot for $500. it was running fine and had had a recent engine rebuild and i only planned on having it for a month or two to learn stick and tool around in during the winter. i drove it back the first day and it did great until the battery died at a gas station. alternator was working fine and the battery was very old so i bought a new one and asked my brother to put it in while i went to work. this was my second mistake. he put it in backwards and four hours later i came home to a gallon of gas under my car. turns out the fuel pump relay was stuck open and the running fuel pump flooded the crankcase spilling onto the ground. i got a new relay changed the oil and, still not realizing the battery was backwards, tried to start the car. obviously nothing happened so i took the battery out to be charged. when i got it back i realized my brothers mistake and put it in the right way only to have the same thing happen to me when i turned the key. nothing. no lights or dash or starter. nada. so i swept through the fuses, finding nothing and eventually wound my way down to the fusible links. sure enough the black one was toast so one trip down to the junk yard later and i had a new black fusible link and lights on in my car.

i apologize for the massive block of text but i just want to give as much background as possible because this is where my current problems start. even when i had lights all i got from the starter was one click. so i checked the battery. full charge. pulled the starter thinking it might be the solenoid, it passed all of the tests at o'reillys. the terminals are fine and everythings plugged in and i just dont know what to check next. thanks for reading through my whole life story. any advice will be greatly appreciated.

Pull all the sparkplugs and crank it over to clear the gas out of the cylinders. If your lucky it may start after that, but you may have cooked important electrical parts.

 

If you junk the car, save the rear differential. Its worth $300 if it has LSD written on its sticker.

like said above pull the plugs and clean out the fluid.  if that doesn't change you might try hooking up a remote starter.  you don't have to use a remote start, you can manually jump the starter and see if it spins but its rough on parts and pretty dangerous so I recommend the remote starter.  its only $20 or so and its a very useful tool anyways.

 

anyways jumping  or remote starting will bypass the ignition and electrical system and let you run the starter on its own.  

 

I think you will find that draining the fluid from the cylinder will help though.

thanks for all the great advice guys. id never heard of hydro-lock before. ill definitely get out and try and to clear the engine once this shitty weather clears up. no use getting the gas out of the engine if it just gets replaced with water. just making sure, you guys think that its gas from when the engine flooded that's hydrolocking the engine? it would make sense giving the engines history but im just curious, cant gasoline be compressed? if so wouldn't it just compress to the point of ignition and cause knock but then go back to normal after the excess gas was used? or is it just that the starter cant compress it to that level all by itself? not really crucial questions im just interested.

thanks again guys

I just put 2 and 2 together from what has been posted here in the past. The car was owned by a fellow member johnw.

 

He is from the Portland area and had an add up needing to sell it to pay lot fees.

 

I wouldn't have guessed it If you didnt say you bought it off an impound lot,Its not the most common car to be hanging out in an impound

 

Good luck

The guy who owned this lives in Sandy and traded his 86 rx sedan for it from a teen not knowing how to get it running. So a long story short on how it got impounded he got pulled over for a loud exhaust and he didn't have insurance on it. Hopefully he pays me back when he has a chance for the rear part of the drive line on this and a grill but that's another story. Hope you get this going again it ran really good and strong when it was at my house about a month and a half ago. This does have the LSD under it along with the dual range awd trans.

Also if the pump pushed gas out the injectors into the cylinder that means that at least one injector is leaking.

 

And the other thing that deosn't make sense.

 

IF the battery was backwards, how would the fuel pump run the correct way and pump gas?  Or was it running in reverse and pushing gas back into the tank sucking from the return? Could have filled the charcoal canister and leaked gas from there?

yeah this is definitely the same subaru! thanks again for the sentiments guys!

anyways i watched some videos of people dealing with hydrolock and they all just pulled the plugs and turned the key. i just pulled the plugs and tried to do the same but my starter still wouldn't budge. just one click per turn of the key coming from the solenoid. is there something im doing wrong? shouldnt the starter be able to turn over the motor if the plugs are out? wouldnt it just push out the gas as it turned over?

and gloyale i dont think it was leaking from the charcoal canister although i could be wrong as i dont know exactly where its located. the gas was dripping off the oil pan coming somewhere from the engine.

hi,

 since you have the plugs out,  put a  socket /W  ratchet ( 21-22 mm i think) on the crankshaft pulley center bolt and turn it by hand, at least see if it will turn,  this will determine if the motor is truly locked up,  or if you now have a starter problem as well as the fuel issue to deal with.  if the battery has been hooked up a while since all this,  it may be drained , because there is no way yet to tell if electrical problems were caused by the battery backwards episode.   it might have toasted something that now causes the battery to draw down , bad diodes in the alternator come to mind after something like this.

so i finally found a half inch driver to fit into my 22mm socket and the engine spun over freely. i also tried jump starting it to see if it was the battery and it made no difference in the starter movement. still just one click. any more ideas guys? thanks for all your help so far!

Try jump starting it w/a screwdriver at the starter.

Short the solenoid to the big positive w/the screwdriver.

If it starts now,problem is too much resistance in the solenoid circuit.

Since the starter solenoid has such low resistance,a small amount of extra resistance will drop the available voltage excessively.(you can measure it at the solenoid)

Usual culprits are bad ignition switch contacts,melted ignition switch connectors neutral safety switches and bad harness connections.

(you can measure the voltage drop across any of them while operating the starter to find the trouble spot(s))

 

A common work around is to install a relay to bypass the heavy current around the ignition switch etc.

 

If it did not start w/the screwdriver and battery and connections are good,then it is bad contacts inside the solenoid.

They can be replaced for about $5.

Bad contacts may be an aggravating factor in the first scenario as well.

so earlier today i found a good deal on another starter and bought it and put it in. a new starter didn't change anything so i tried chopping off the old melted connector and put a new one on. no luck. im almost positive it isnt anything in the starter now as the chances of two starters having the same problem are slim. could it still be the starter contacts? i havent had a chance to have someone bang on it yet.
