Well, it was late, but i got my charged battery back from my friend's house, and tried to fire up my car, wouldn't even turn over. So I pull up my dad's Subaru, we hook up the jumper cables, and I crank it, still goes slowly, even after a charged battery and redone grounds. My dad looks skeptical. I try to start the car again, this time, I give it some throttle, keep cranking, give it full throttle and the car fires!!!! In this wonderful moment, I get scared, because this is a new thing to me, and I let off the gas, and the car dies, only able to show it's glory for about 3 seconds. I try again, and my brain still can't control my muscles, I let off the gas again. Being 10PM my dad says to call it a night, and to try some more during daylight hours. Anyways, I'm very happy that my car fired, but on the other hand still wondering why the car is turning over slowly. Maybe the starter isn't broken in? I cleaned off all grounds, checked all connections, even put on some new terminals, maybe the starter isn't broken in, or too tight? I'm open to ideas, anyways, I'm calling it a night, I think I'm too excited to sleep though.

When I was first fixing up mine, it didn't crank at all. Then I got a rebuilt starter in it, and it cranked REALLY slowly. After taking the starter back out, I noticed it was missing a bushing on the end of the main shaft. So, I took it back and got another replacement, and now it cranks just fine. But now that I think about it, the odds of that same thing happening to you must be very low.

Did you replace the actual wiring to the started. Some of the wires might just be complete crap by now. I have never messed with the started but would it be easy to measure the voltage at the starter? You could also test the starter wires themselves for resistence possibly.

Have you thrown away that dead battery yet??? Remove the cable from the battery and run it directly, solely, off of your Dad's car.

The battery's probably sucking so much current it's stalling the car through the alternator.

that doesnt always work , jumper cable clamps dont make good enough contact to drawn the high amps needed to start a car . BTDT. you need a good battery in the car .

[924RACR]

Well, if they don't make a good enough contact, that's not much of a jump, now, is it? Fix the contact, get it clean. I still vote that the battery's gotta go.

Okay, well it idles today, i looked over the engine compartment and noticed the intake boot came off of the fuel distributor....silly me. Car started, but i had to keep it floored for a bit, and it stayed at about 1000rpm despite the full throttle. When I release the throttle, it actually stays alive, but the it idles really low. I'll replace the battery first thing, and my gas is old, so I'll add some STP and play with timing, mixture, etc. Thank you once again for all the help this board has given me. It doesn't rev up, but it runs, and hey, that's good enough for me right now.

I had the same problem with my car on initial startup. It would only start with the pedal to the metal and idled very low. These symptoms suggested a timing problem to me. I set the crank and cam to their TDC positions and pulled the distributor cap to check if the rotor was pointing to the number 1 spark plug position. It was not. The Haynes says to line up a mark on the rotor with the line on the distributor body. I couldn't find a mark on the rotor so went with the centre of the rotor lined up with the line on the distributor body. This involved removing and re-positioning the distributor body. I was careful this time to ensure perfect alignment.

This manuver got the car starting much easier but still not running right so I then adjusted the idle speed as best I could and hooked up the timing light in order to set the timing to spec. Now the car starts on the first revolution of the starter and runs at a steady 950 rpm. Put the new battery in and carefully check for proper ignition timing. I was amazed at how far out the timing was and that the car would start at all.

I did the same thing, Pulled the whole distributor and made it line up with the no.1 cylinder plug, it should be withing 2 or 3 degrees of TDC, I'll get a timing light and fool around with it later this week. Right now I need to replace my fuel filter and redo my valve clearances.
