120319, Starting problem.
Posted by 96NTeclipse, Dec-20-06 04:37 PM
Alright.. lets see if anyone else has had this problem before. Sometimes the eclipse will start perfectly fine, but other times it take it about 5 seconds of cranking to get it started. When it really wants to be a bitch, it will take a couple of 5 sec tries to get it started. When the car starts it runs fine. It does not stall, miss, or give any other kind of problem.

As far as the basics. The plugs are brand new and the wires are fairly new (10000 mi old). I have an MSD coil on it that was put on the car the same time the wires which so happens to be when the new motor was fired up.

The fuel pressure guage reads between 55-60 lbs while cranking which is where it is while it is running. So there is definitely not a fuel problem in any way. In fact it is still running a tad lean with the SAFC set in the + range (can't remember exactly where at each interval). It's not too lean though.. it has a little brown on the porclean but the arch of the plugs are still a little chalky white. I need to get it somewhere that can help me get the mixture nailed before I can even use the nitrous.

I found the numbers to check the resistance on the ignition coil and I'm about to go check it as soon as I post this. Is there any way to test the cam and crank position sensors? I can't seem to find any numbers at which they should be. Chiltons doesn't have the numbers and I have scanned through the online shop manuals on this site and couldn't find any there either.

BTW this damn thing throws so many damn codes that I pulled the check engine light bulb. This is due partially to my car being swapped from a auto to a manual and the ECU was swapped too. So the codes were all from the cruise not being hooked up and other small things like that. So in other words.. I dont' have any codes. But I have all day tomorrow to check the sensors if I can just get what ranges they should be in.

Tested coil last night. It is right between all upper and lower tolerances. So the ignition coil should be fine.

Coolant temp sensor, or idle air control valve?

I didnt' think about the coolant temp sensor because the hard starting does not discriminate between the engine being hot or cold. I will check it though.

I might add that the problem did start all at once. I just got in one morning at the damn thing didnt' want to start as quick as it always did. Before that it started up fine. Now it cycles between being hard to start and starting right up.

Mine had the same problem a few months back and it turned out to be the coolant temp sensor. The guy at autozone said they could test them, now if they really can I am unsure. But if they do and its fine it will save you about $25.

Alight.. I'll check it. Thanks for the input!

Cam Angle sensor, crank sensor. Starter relay on the firewall.

I'm sure it's one of those.

EDIT: and those codes mean something. don't just, not don anything about them. Put that bulb back. :P

I would have fixed it where the light would not come on but I would have to install a complete cruise control system or put another ECU on my car. That's a lot of work when I never use the cruise anyway.

I just started having this same problem about a week ago. Did you figure it out yet?
