Okay I dont know if anyone has seen any of my previous post but heres my current problem. I have a 1991 Na Rx7 that died a while ago. My problem, no spark. This is what happened one day I was driving and shut it off..went to start it...nothing. Anyways waited 40 min. and it started up again. However on way home it died. Got it towed and won't start since. So figured out its no spark. This is what I have checked so far..and yes I have either just tried new ones or am 100% I checked it properly. I tried new coils, new ecu, distributor or Crank Angle Sensor um I have checked all the grounds over and over. Obviously my fuses and igntion wires. SO now I am really stuck and frustrated. If anyone has an idea of what it might be or can give me a list to check that would be great. I would also appreciate it so much as I miss my Rx7 very much

 

Really would like some help here please

 

You need a meter to fix that car. You need to turn the key to ON, then pull apart the small, white, two socket plug at the LEAD coil assy. You put the meter on the black/yellow wire and see if you have batt voltage. Leave the other wire alone in that plug. Write back as to what happened. That's step one. Basic first step. NO test lights allowed.

 

Did that..trust me I am way past that step and I am using meter.

 

Pull the boost sensor plug off and key ON see how much voltage you have on its brown/white wire.

 

Voltage good..

 

Could it be boost/pressure sensor itself???
