problem with vl turbo

[Sik_Cordz]

hey guys i went to start my car yesterday and its not firing. it turns over but no go. checked spark witch seems a bit weak. its got a brand new msd ignition system. 6al and ss coil.check for fuel. got plenty coming out the rail. now i did a ecu code check and its pulling up error 21 witch is ignition signal circuit . now prior to this the car had a ems ecu installed witch to run it needed the dizzy rotor arm modified to change the phasing angle. now ive put back the rotor button to the standard position .now i believe maybe its got a problem with the power transistor witch from what ive read has something to do with the coil. what are you thoughts. i will hopefully put another dizzy in the next week or so

Interesting Al the power transistor aids in switching the coil to ground for the spark cycle

ok that could explain why i have such a weak spark perhaps. im borrowing another dizzy to try and ill give all the plugs a spray with wd40

The transistor is probably fine but if you have a spare lying around swap it in for good measure. How's your battery charge? Yeah let us know after you throw the new dizzy in, I'm about to throw a spare on in myself to try to get mine running again lol

well car is running again. had a problem with the crank angle sensor plug and timing wasnt set quite right. but all running now
