I just bought a 91 Galant GSX and am unable to get it to start. I bought it in non-running condition. So I need some input here in case I'm overlooking something. I've been a DSMer for six years and have a lot of experience with the 4G63 but I'm stumped with this one. Here's what I've done:
- checked base timing. With the #1 piston at TDC, all the timing marks line up perfectly. Tension on the belt is correct and there is no slack anywhere
- checked for spark. I tested each wire separately for spark and every one checked out. I also put a set of known good plugs in
- checked for fuel. I pulled the line going into the rail and cranked the motor. There is definitely fuel feeding the rail
- checked the CAS. First I made sure that the cas wasn't inverted 180 degrees, then I removed the cas and put the key in the 'on' position. I cranked the cas by hand and could hear the injectors clicking. I was told this is how to diagnose a good cas /ubbthreads/images/graemlins/dunno.gif
- checked battery connections. I sanded every ground, battery posts, connectors, and positive connector. Everything is clean
- checked for air. All related sensors are plugged in, etc.
So, basically when I crank the motor it seems vastly underpowered. It seems to crank slowly instead of aggressively. At first I thought I wasn't getting any spark because it feels like the motor is turning under it's own power without any help from combustion. Since I did all the cleaning up of the connections, it cranks faster but still not strong. *I will point out that I had the battery hooked up to a running vehicle while I was testing this so there was no shortage of voltage at the battery.
In conclusion, if anyone has some suggestions, let me have 'em! Additionally, I would like to know if the starter can be swapped out for another (like from a Talon or Colt) and which model would fit appropriately.
Thanks.
