new to the gn world with a missing problem

[ajohn302]

i recently bought a 86 gn that has been sitting since 2000 . it started up fine but is missing on the number 3 and six plugs. i put new plugs and wires also coil pack... no change no fire to those plugs any ideas no experience with gns thanks john

If the coil is not firing on those 2 it may be the module located under the coil
Welcome,Were are you located?

shreveport la i think its why it got parked it had an extra wire on it with the stock one still attached in the looms. thanks , thats the module that the coil screws down to? John

 

[Otto J]

yep.
Are you positive its missing spark on those 2 cylinders?
After sitting that long,Its possible the injectors could be clogged with
bad fuel.

Wow, just got it and already slapping on parts to solve issues, welcome to the club.

IF it is missing spark ( pull plug and ground to metal to see ) then clogged injectors or an injector related issue like Otto stated would have been my next guess since you replaced a lot of parts already. The injector harness could be the culprit, Caspers Electronics has those new.

LUCKY!!! I wish my GN was missing some of it's problems!

Assuming you're missing spark and the coils are good I would check the module or maybe try a different ECM.

thanks,,, 3and 6 are not firing for sure all plugs are out and grounded before and after coil,plugs and wires changed, no change with old parts and new. gas tank was dropped and fuel changed. they are across from each other on the coil on the end does this mean anything? maybe i should stick to what i know... ha ha i had one other turbo , a 86 turbo t but it never gave any trouble. i bought this car pretty cheap so i couldnt resist but it needs lots of tlc... thanks john

Same Freakin Problem I Have

Hello People

I have the same problem as "ajohn302" had, i bought the car after sitting for 8 years and has a miss and slight ticking sound from top of engine. I did all the plugs, wires, oils, filters to specs, still has the same problem, runs like crap, bought a scan master, i t shows no real problems, no errors ( i think), it struggles to drive.
I had someone check it, they changed the coil pack still did it, same missing on the 3 and 6 cylinder (dead cylinder). they put the tester device to the injector harness, it shows it firing to injectors, but who knows if enjectors are bad/clogged...right
Mechanic said to try changing the injectors first (they have 60lbs in them), if its not that then he thinks it can be the cam is bad, and might need a refresh.
what do you guys think.
the previous owner changed the tank, i put new fresh gas in it..
I really need some good advice, i dont want to do a refresh if i dont have it..especially in this econy...jeez
