i have an 87 rx7, the problem is that im not getting any spark, however, ive checked the coils and even switched them with another set from an 87 t 2.....and still nothing. the motors spinning, its just not starting. does anyone know of any other methods i should go about using?

 

um...........so it's not the coils.........is it making ANY noise? can you post a vid of very DETAILED description?

 

Set the key to IGN and remove the CAS. Leave it plugged into the harness. Spin it with your finger. Do you get spark?

 

IF your tach makes small bumps up/down when you spin the starter, then you have spark.

No tach needle bumps? Is the ENGINE FUSE in the interior good or bad? Bad? Replace same.

Good fuse? Then make sure the fuses in the engine bay are good. The ones called EGI Comp and EGI Inj (series four).

Real sure you have no spark? How sure? Pull a sparkplug wire off and hold it in your bare hands. Other hand touching the bare metal of the chassis or engine. Spin the starter. What were the results?

I wish somebody that has a heart pacemaker would do that. I'm curious if it would effect the pacemaker or recipient of the pacemaker.

Personally, if the fuses were good, I'd do what Cake said above.

 

sigh NO GO no spark and no bounce on the tach...BUT the CAS im testing out worked on another car.....im flabberghasted! lol thanks for the help if anyone else can give me a pointer please chime in!

 

Check the ignition coils for 12V with the key set to IGN. Check on the black/yellow wire.

 

the airflow meter could be a problem. i tried for a month before i figured this one out on my old 86 gxl.

like an idiot i removed it via the screws and yanked that innerds out. remarkably i still drove it to school. only to die on me. no spark nothing. i got fuel and whatnot, yet erverything was completly in spec.

try unhooking the airflow meter and try starting up the car.

 

ROGER! we shall give that a shot ill be checking for volage at coils as well...ill be back with the status of the situation!

 

check you Fuses inside the engine bay....i blew my EGI comp fuse and i was getting no spark either....

 

or time for a new ecu i had this promblem in my s4 damn ecu
