Injector pulse problem

Featured Replies

Don't have a manual around for this beast yet (probably get one this afternoon) and am having to use a different dist. for it.

Am working on a 87 turbo wagon using a 87 carbed dist.

Am not getting any pulse to the injectors. Is the pulse coming off of the dist??

Original dist. has four wires and the one I'm using only has two. Figured that the other two were for the knock computer and was just bypassing the computer for the moment.

Anyone know if the injector pulse comes from the dist (directly or indirectly)??

 

Hush

Can't tell you absolutely, but I think you are SOL with the carb dist. The MPFI/turbo dist has a crank angle sensor that tells the ECU when to pulse, and the carb dist doesn't have this sensor.

did the old disty have the vac advance, and is the map sensor a flapper or a hotwire?

if its a flapper, then the negative side of the coil gives the computer the injector pulse signal.

any ea82 carb disty will readily swap in to the flapper maf systems.

 

if you have a hotwire system, you need a newer style disty.
