ECMlink New injectors wont start

[gst-turbo]

Hi the car has been a daily for a few years now and finaly got another daily so I decided to install new pte 1000cc injectors. The car won't start I played with the global fuel and deadtime but no luck. Car ran 100% before the injectors and my profile is up to date. Any help and advise would be appreciated. Don't have much experience with ecmlink only been using it as a diagnosis tool.

Post a log so we can get a better idea of what’s going on. Are you running SD or Stock maf? Do you re install and reset fuel to see it’ll fire up? Make sure clips are seated on injectors?

 

[gst-turbo]

I can't even get the car to idle. I tried today to reset the fuel to stock but still just cranks no start and I swap back to stock and car started right up no problem. I'm running stock maf been playing with the global and dead time but won't start at all any ideas or something I can try next

Can you tell us anything else?

What are your settings?
Does it smell like fuel?
Are the plugs wet?
Does it refuse to run at all?

 

[gst-turbo]

-55 for global and 420-500 for deadtime been playing around. I just when out side and pull the plugs and yeah they are black and there is a small bit of gas in two cylinders but the other two don't have any fuel. The car refused to start at all just cranks.

Did you check to ensure you have spark?
Post a log with you attempting to crank?

 

[Vegas Smith]

Make sure you plugged your coil and ptu back in.

Have you tried swapping back in the old injectors to know they are in fact the issue?

 

[gst-turbo]

I have not try to check for spark will do that tomorrow and I will also post a log too. I pulled all the plugs out and inside of the cylinder there is a fuel puddle. Its almost dried up now but my oil smells like fuel too. Plugs are supper black but drying soon I hope

Here is the log of it cranking.

Were you able to swap back to old injectors and see if it fired and ran?

I think the above quote says he did try that, or am I missing something?

 

[d1prospect]

what caused you adjust timing and fuel via da table? are current settings in link what you've been adjusting around to get the car to fire? did other injectors fire with these settings?

I had this same issue. I built my engine around 2006. installed fic 950cc. I have not driven the car in years being I was overseas for a while. had the fuel injectors cleaned in 2013. 2 months ago I was back to running on 3 cylinders again. took them in to get cleaned again, and the guy told me it would be better to just get new injectors. I guess with 10% ethanol in fuel now, a car sitting for a while with today's gas is not good. So I ordered brand new fic 950cc injectors. no start? i have a aem ems. It sucks but I have no idea how to tune. So after a few youtube videos with the aem. I figured out how to adjust the new injectors to just idle and run, still runs like crap on 1st start up, then after it reaches a certain coolant temp it runs 14.7 at idle. I need to go to a dyno and have it tuned again with the new injectors.

I guess what I am getting at, is that every injector is different. I noticed that the ohm resistance was different from the old injectors and the new ones. not much, but enough to throw the tune out of wack. I called up UMS tuning who originally tuned the engine, and he confirmed that, yes they are the same size injectors but they need to get tuned again. So I guess later this year back to the dyno, and finally get a classic rod plate to finally drive the car again.

So in the log there is two parts too it the first one is it cranking on the settings were I adjusted them to the new 1000cc injectors. Second part is how the car usto run with 450cc. Two cylinders keep filling up with gas the other two are dry. I'm open to any suggestions

 

[wrencher]

You changed global deadtime AND InjBatteryAdjust in direct access?

 

[gst-turbo]

No I did not I changed it in direct access I changed it in the fuel tab

 

[wrencher]

In your log they are adjusted up from stock?

Revert InjBat back to stock or zero out the global.
Then dry it up get it fired & tune the idle/part throttle fuel trims.

 

[gst-turbo]

Yes they are adjustable up from stock and im give that a shot tomorrow and report back

 

[AWD-Tony]

What's your base fuel pressure?

 

[gst-turbo]

My fuel pressure is 42.6 stock and just when out and gave it a try again and changed global to zero and it just cranked no start. Pulled the plugs out and again two of the 4 cylinders are full of fuel again. I might be ready to just throw the stock injectors back in because I tried everything. I'm not sure why the same two cylinders are filling up with fuel ever time. I dry them up with the compressor. Could it be I have two bad injector? I going to try to swap the injectors to different locations to see if it fill up a different cylinder

your injectors actually have a flow rate of 940cc. Your global should be -51.2 and your deadtime should be 450. You need to change the injectorbatteryAdj in DA back to stock, you can simply load the direct access table below, I put them back for you.

You'r battery during crank is at about ~10.6V which means that you are adding almost 500usec to the deadtime due to the modified DA table. You are trying to start the car with -55 global and 950 deadtime; when it should be -51.2 and 450cc deadtime.

Also, if you've been cranking the crap out of it then you will need to dry out the cylinders and dry of the plugs before it will fire with the correct settings. You also might want to try opening the throttle a little to give it some air during crank. Your ICS is wide open. Also, Can you post a picture of your engine with the spark plug well cover off? Are you positive that you put the plug wires back on in the correct firing order.....

I know your profile says stock, but I also have to ask if you are using a 95 cam sensor still.

I tried the above and loaded the tables on to my car. Been trying get it started for a week now with no luck yet I'm on the stock 95 cam sensor. I checked for spark and they all have spark everything is dried up. When I had all the spark plugs out of car I cranked it and two cylinders were getting full with fuel bad. Could it be bad injector? Is there a way to turn down the fuel to just one injector so it don't fill the cylinder with fuel. My battery keep draining so I have a battery charger on it ever time I try to start the car I know that changes my injector dead time how would I adjust it according to voltage? Might go and buy different injectors because the pte have been sitting for a long time

Sometimes when you get an engine flooded they can be pretty difficult to get it cleared.

I'm guessing with a full charge on that battery you've also cranked it over with the gas pedal fully depressed as in clear flood/no fuel delivery mode?
You could also disconnect the injector resistor & try to get it going.....

If its being so difficult you may need to swap back clear the flood out get it running.
Then maybe swap back after to start fresh.
It seems like you had an issue but all these attempts are compounding the no start with a$$ tons of fuel washing your rings down.

As for bad injectors sure it can happen but its not too common .
