Attention: Since my "sizeable" contribution earlier, Luke is no longer accepting sperm donations. Just US Dollars, he says.

On a no-homo note, sounds like a good idea - your time is definitely valuable, and I'm sure it's worth it to the people you help.

I retract my previous statement. It's leaking out of the rail, right where you can see the visible part of the injector top. It's not really gushing, not dribbling either though. O-rings? It's happening on 3/4 the injectors.

Sounds like the injector to rail o rings. They should always be replaced whenever an injector is removed.

Battery tested - Good
Starter tested at Kragen - Good
Ignition Switch - Looks fine, I was able to replicate the issue using a screw driver, so it's not getting worn down or anything like that.

You told me to check the cold start wire....well heres the thing...the car was running fine for like a month before this issue started. Could the starter still be bad even if it checks out okay at kragen.

yes starters can check out good even if they are bad. alot of times there is a internal short around the motor windings. i have had a few bad ones on KA's there is a wire in the end cap i think it is that the insulation on it can rub through and cause a short and keep it from cranking over. It has been years and years since this last happened to me so i forget exactly where the wire was rubbing, but i fixed it myself and never had the problem again.
I have also had more then one brand new starter from parts stores go into cars start once or twice and then not start again, then take it for testing and it works.

That's true, but not most of the time - check the connections and condition of the huge black/red wire coming off your starter going to the battery + terminal. If it's good, get the starter rebuilt.

Luke,

Got a problem for you. The engine seems to stall on me randomly. When I'm driving the engine just cuts out. This happens randomly like waiting at a light and driving on the freeway. I've noticed it happen at different RPMs, all gears, any temperature. It's weird because since it's random I can't find the condition that makes this happen. After it happens I pull over and try to restart the car. The engine won't always start up right away but it will always crank. As soon as it starts I can drive away no problem. I've checked for loose cables (etc) but no luck. If you know a quick fix for this I would be most grateful.

Also, I'd rather pay for your time so if I could make an appointment at Manji for diagnostic/repairs please PM me so i can get in touch with you. I'm pretty much free the next 2 weeks.

Thanks

I have a no start issue. My engine seems to randomly decide when it will crank. I know I am getting power and have no blown fuses. It can be push started as well. What do you think?

That's what I was thinking but it was a very sudden problem. It never has been a week starter, always starts on like the first or second turn over.
