hey guys, I'm just pulled the following codes and am wondering what is causing them:

556 - fuel pump relay primary circuit fault
(maybe cuz of running gas tank too low?)

212 - ignition tach signal erratic or SPOUT circuit fault
(no clue on this one)

332 - EGR no response
(egr may have been deleted, not sure)

thanks in advance.

 

Anybody???

 

Well, the description of the codes is pretty much telling you what part malfunction is causing the code.

 

I guess maybe it's time for an MSD ignition coil and maybe a new distributor cap and rotor lol

 

A tune up is never a bad idea but I'm not sure how an MSD coil (the stock TFI is totally adequate) would solve the code throwing problems.

 

I dunno, figured if the ignition circuit is having an issue, maybe replace ignition circuit components?
