New start-up help
« on: November 02 2017, 01:30:44 PM »

So after years of putting it off, I'm struggling to get this motor to run right. At least while its still on blocks in the back of the garage. I'm trying to get it to start and idle. Will only start with the throttle partly open. Struggles to start without the throttle open some. (25-40%?) Then its a struggle to keep it running. Anything below 1000 rpms and it stalls. Forget trying to get it to 500 as the IAC setting direction say. Resetting the IAC hasn't seemed to do anything but run down my battery from starting it multiple times. Does the motor really need to be warm for this to work? Also I don't have a check valve in the fuel system yet. I don't see how its really needed for this.

Chip I'm using is a street 009 I got with the injectors. (too many years ago) so I don't know the specs. Translator set at all "0" Fuel @ 42.
UPDATE! Just went out to look at the plugs again. Changed them out yesterday.
This plug is no more then 20 minutes old. They all look like this. Which is why the long I ran the engine the harder it was to keep running I guess. Is it possible that all the injectors are bad? Its not blowing smoke. Something else?

Time to hook up a scanner and see what the pcm is doing. It could be one of many things.

What are your coolant temps reading?  Could be a variety of things.  A bad temp sensor would tell it too dump more fuel.  A bad ground.  Or an electronic problem.

The temp never got much above 100. I was trying to set IAC. Start and stopping the engine.The first time I had it running I did have the temp up to 150. Was running crappy is why I checked/changed the plugs the 1st time. They looked the same. But with that run, I started seeing plums of smoke (suddenly) I had that happen once before on my T-type and it turned out to be an injector. This time I had a bad vac leak at the IAC and the PCV was stuck closed so I thought it had something to do with that. All so had the original chip in and the Translator not set right. This time with that all fixed I had no smoke. Still fouled the plugs.

What is the brand of the chip? Is it burned for those injectors? What is the fuel pressure for that chip...line off.

Can you take a pic of the chip on both sides and post it. With the car sitting for so long I'm wondering if the injectors are gummed up.

Do you have Direct Scan? I know you said the next thing to purchase was Powerlogger. If you have a Scanmaster, is it throwing any codes?

Maybe exercise the translator switches then set them back to where they should be.

No codes and no DS.
Plugs!? All I had on hand were 42s. Didn't think it would make a difference for just a start up.
 MAF#25168491 Do they go bad just sitting?
Oh..SM did throw a code the 1st time I tried starting the engine. 45- Ox sensor rich. I cleared it and it never came back.

Delphi LS1 comes up as the part number. That's an Extender chip? Thot Bob would have marked it better.

The car is obviously running extremely rich from the look of the plugs

Typically, I would think bad maf.  If the car has a translator, then it could be the translator set up.  Or, it could be a chip set up problem if that is an Extender chip but for some reason, that does not look like an extender chip to me but I have not seen many.

Or, if the chip is thought to be an extender chip but is not, it might be the translator is set for extender but it's not an extender and the ecm is seeing the wrong maf numbers as a result.

Without data, it's all a guess.

Yup my bad!

Doesn’t look like and extender Bob uses a code by injectors, octane, boost and rev limit
