Ignition issues

[bskills]

Hi guys, Need some help here.
One morning I started my car and first thing is realized was that my RPM meter wasn't working. After driving for a few miles, my car started to run on 2 cylinders. Further checks revealed that #2 & #3 wasn't getting any spark. So far, I checked my ECU, injectors, Plugs and Wires, even changed my fuel filter and all are ok. Any input will be greatly appreciated.

Coil Pack. Or CAS

having the same problem

power transistor

Power transistor or Coils would be on the top of my list.

on a 91+ the power transistor would be the only thing to drop your tach signal. even if it is firing a bad coil you'll get the correct tach signal.

The manuals show the tach gate on the output side of the transistor and I assumed it needed to see the pulsing 12v from the coils to trigger its signal. I guess it would be easy to test by just disconnecting the coil pack and see if you still get a tach reading on the gauge to prove one way or another if the transistor is the only thing that could drop you tach signal. I don't believe it is but I'm interested to learn otherwise.

 

[ramsack]

yes that makes sense especially as the manual says when code 44 is present that it could either be the power transistor or coil.

Thanks for all the feedback. I have a mechanic who is coming by today to take a look. I will let you all know what was the final finding

It was the power translator. I played around with it and the car would catch a few times. Swapped mine with an Evo 3 and it worked like a charm. I also ordered an extra one for a back up.

Power transistor?

 

[bskills]

power transistor. No coordination with my head and fingers. Sometimes, its the little things that causing the biggest issues

 

[steve]

Did it really take a year to swap it or are you just getting around to posting an update?

 

[bskills]

I Just decided to post an update. In case anyone who sees this tread, they know that I was successful. I have been doing some upgrades to the car, but so far, everything is working good. About to get it tuned with ecmlink v3. Looking to for 400HP.
