shift Posted November 9, 2006 Share Posted November 9, 2006 ok my car is toast here are the symptoms: blew up my alternator, and shorted out a wiring harness, also drained my battery. i took care of replacing my battery new alternator and new wiring harness. and now for the weird s h i t : after wiring all of it back up and making sure everything was good to go, i started my car and it took a few cranks t get it on, and it only was running for like 15 seconds. THEN i thought it was just trying to warm up, so i took it down the street and it sputtered and died when i stomped on the gas and tried to give it a run for the money. and it spuddered again and died. but it will start back up every time i start it. wtf is my problem? i have another carb that im thinking about putting in my car just to make sure its not the carb. i was also told to make sure when my car is running, the battery is clocked in @ about 14 volts and 12 when off. what about the alternator? what is it when running and not running?

Subaru_Mechanic Posted November 9, 2006 Share Posted November 9, 2006 what year and modle? did you check ur fuel lines? (filter and pump) Quote Link to comment Share on other sites More sharing options...
DerFahrer Posted November 9, 2006 Share Posted November 9, 2006 It sounds like you have the same problem I have. What's your system voltage? I'll bet that in all the electrical horror, you screwed your voltage regulator. Quote Link to comment Share on other sites More sharing options...
Subaru_Mechanic Posted November 9, 2006 Share Posted November 9, 2006 if it starts and you can rev it up good then i say its a timing or fuel problem, but if it starts and it wont rev right then yea subyluvr2212 advice should help:) Quote Link to comment Share on other sites More sharing options...
NoahDL88 Posted November 9, 2006 Share Posted November 9, 2006 I'd say 98% that its something that you changed/fixed, unless you recently messed with the carb, its probably not that. Make sure that all your new harness connections are soldered, not just spun and tapped together. The battery should be at 12.7 or higher resting, and over 14 with the alternator running. Which harness did it short out? are there shorts to grounds in the harness? Year/Model could just be out of gas. There are 2 syles of EA-81 Alternators, one has an internal voltage regulator, and the older style has an external, if your car takes the newer one, and you have the older one, you don't have a voltage regulator, which could cause harness fires and all that fun stuff.

DerFahrer Posted November 10, 2006 Share Posted November 10, 2006 The reason I said voltage regulator (the external ones anyway) is because they contain the fuel pump relay. If that voltage regulator is b0rk3d, then the fuel pump won't get juice. Shift, hotwire your fuel pump directly to the battery and see if that allows your car to run continuously.

shift Posted November 28, 2006 Author Share Posted November 28, 2006 yes i finally got my car running!! woo hoo! it hauls rump roast just like it did before too. my problems were: 1. alternator went out had to replace it 4 times, untill i found out the spark plug wire was dbl grounding aginst this metal that held the ac compressor in place and hit the alternator and fried it. 2. then i got everything working and then i blew my fuel pump while running my car @ 16 volts lol. 3. bought a new fuel pump and voltage regulator and hooked everything back up, cranked the car for like 5 1 seconds and she sparked and ran! tested everthing, battery alternator and voltage reguator and all semed to be in good grounds. 4.battery was @ like 13.65 volts when running, and then the alternator was @ 13.25 and regulator was @ 12.25 i believe. but i am stil having this problem with my carb. ill be 3/4 of the way through my gas pedal and when i go to stopm on it, it wl spit and then lunge foward with force and i will take off. what could that be? dirty jets? or dirty carb?

DerFahrer Posted November 29, 2006 Share Posted November 29, 2006 Wow, a GenI owner that says his car hauls rump roast. That's encouraging . I'm still a carburetor n00b, but I would think if you stomp on the pedal and the car stumbles, that there isn't enough fuel coming in to meet the new volume of air coming in. I won't say anything definitive though, the veterans can tell you. Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted November 29, 2006 Share Posted November 29, 2006 sounds like you need to replace the accelerator pump inside the carb. Quote Link to comment Share on other sites More sharing options...
