Very rough idle and fuel leak on rail

[jdog]

What plugs did you install, where did you get your injectors?

[Jesse J]

Injectors numbers 0 280 155 710 Bosch I got of eBay 

 

ngk v power just what the dude at Napa gave me when I asked for copper core

[cruiser54]

710s are not the correct injectors. And, are ALL plugs wet, or just certain ones? 

[Jesse J]

ok. I didn’t check all of the plugs last time but I just did and all are dry except for 3 . In checking them I messed up 1 maybe two spark plug wires. I can take some off my xj but the xj is down at my moms house rn so it will be a day until I can get those on

[Jesse J]

What should I do?

[cruiser54]

Have you replaced plug wires, cap, and rotor?

Look real closely where the injector harness passes from the firewall to the back of the valve cover. Any wires rubbed?

 

You could also reinstall the original injectors.

You need the 746 injectors.

[Jesse J]

Thanks fiat. 

Have not replaced cap or rotor. No rubbing of wiring. I put my old injectors back in until I can get the right ones. 

[cruiser54]

And????

[Jesse J]

havent even attempted starting it missing 2 wires

[Jesse J]

I got it to start except for a huge fuel leak at injectors 4 and 5 where they attach to the fuel rail

[Jesse J]

I can't think of a reason that the old injectors would leak so bad. O rings hopefully?

Sounds like bad o rings on the injectors.  One might have gotten torn during removal/reinstall.....

Lube the new injector seals with clean engine oil when installing.

Lube

A general series of rules for life: Research a little and find the correct type of lube for your application. Add what you think is plenty of lube for the job . . . at hand. Then add some more. Finally, lube is useful even when you think its not needed and almost never hurts to use anyways.

 

I recommend sil-glyde for lubing orings, including those for your injectors. 

[Jesse J]

So took my o rings off the wrong injectors onto the stock ones and so no fuel leak anymore and it fired up a i I took it for a drive and it went for about 4 minutes and died and doesn’t want to start

Check the cps connector/wiring didn't melt on the exhaust
