Tachometer problem.

[clss240]

tach kinda bounced around a bit and then went to zero while on the freeway. now every once and a while it will bounce around some then remain at zero. Mostly it stays at zero. also possibly related? my odometer hasnt worked in while probably 3 or 4 months before the tach stopped. anyone know why and what i might do to fix it?

i think you have a bad cluster. the tach and odometor are unrelated, unless you have an ecu problem. try replacing the cluster and you should be alright.

cool, thank you, also this is in a 89 s13 sohc

im having the same problem with mine too, but my aftermarket tach is doing the same exact thing, i just got a new ecu and its still doing the same thing. and my odo works fine

sounds like you have a problem with the coil. i belive the s13 gets the signal from the coil, s14 from the dizzy (internal coil). try changing out, prob will fix your problem.

Stock Tach gets its signal from the ECU. Most aftermarket tachs just tie into the coil.

sounds like cluster problem to me.

his aftermarket tach is doing the same..he stated that. it has nothing to do with the cluster if the stock tach and aftermarket tach (which im assuming is wired correctly into the coil) both have the same symptoms.

the only way i could figure out to do the tach was to connect it to the ecu, which is how its been hooked up for 2 months with no problems. i think the coil might be the problem though since thats where the signal comes from because i replaced it becuase i was having ignition problems, but it didnt fix it so i took it back, but the coil was pretty ugly, im not going back to auto zone and paying 170 bucks for a coil though, i know my rpms

You are confusing two differant posters.xru5tyx said his aftermarket tach was doing the same thing.clss240 (the original poster) made no mention of an aftermarket tach.

If an aftermarket tach is taped into the coil and cuts out but the car is still running then you have a power or ground problem with the tach instal. Or posibly the pickup wire is not connected solidly.

If a STOCK tach is not reading correctly but the car is still running, then it could be a ground issue or a bad cluster or posably a bad ECU.

are you high or something...lol i already ANSWERED the first poster a few months ago and answered his question, then another one asked a similar question which i then gave a different answer for a different problem. damn man read before you type s***.
