I just had a motor professionally rebuilt.Ｉnoticed that the front housing spark plugs are clean as a whistle while the rear are. burnt. I am getting spark and fuel but for some reason the car is running off the rear rotor. I have only let it run for about 5 mins because of some leaks I need to address. All seals were replaced,housings were resurfaced. It's an 86 na.

 

this should be pretty easy to troubleshoot if you were able to install the engine yourself..


check for spark, check for fuel, check for compression.

 

I did install the motor myself. I checked all the grounds. Im wondering if i let it run for a few hours on its will the seals set in

 

Housing can't be resurfaced only the plates. Some people have resurfaced housings but im positive the shop you went to didnt since it cost as much as new housings. Whats your compression numbers? What shop did the rebuild??

 

did you check for the 3 things i listed on each rotor?

find out why it's running on one rotor instead of running it and hoping it fixes itself.

 

Double check your injector wiring. If the plugs are totally clean like nothing is happening in that housing, then perhaps no fuel is getting in there.

 

yeah if plugs are clean then you have an issue with getting fuel in there more than likely

 

will do, thanks.
