serious car won't start porbs
My car has been down over 3mo. And I’m lost as to what could be wrong. Here’s what happened.
Picked my car up after work drove home as normal, parked in the garage and turned off the ign and let the turbo timer turn off the car. Came back about 30 mins later to go to the store and the car would crank but not start.
first thing to find out if it’s a no fuel or no spark situation. Plenty of fuel no spark.
Things I’ve done
1. check plugs, ok but replaced anyway
2. swap dizzy with known go dizzy
3. replaced cap and rotor
4. replaced blaster ss coil
5. check msd for spark per their instructions, check out good but decided to remove msd to get ign system as close to stock as possible.
6. Pulled timing covers verified timing and checked crank angle sensor, measured resistance whick checked out good and cleaned sensor and pullies.
7. Measure resistance back at the ecu for crank angle sensor and that was good
8. Measured the resistance on msd wires good
9. I’’m running an aem ems so I ‘m able to change coil drivers which didn’t do it
10. Gave my buddy my ecu and it started his care so ecu is good
11. Ign switch was never replaced on a recall so replaced that.
I think that’s it. If anyone can figure out anything that I haven’t covered please chime in .
Thanks.

Re: serious car won't start porbs
Well umm pop one of ur plugs out connect it to ur spark plug wire. Then ground it to the vc. Crank ur car and if no spark then go from there forget about sensors. If no spark check ur fuses first I'm not sure if u did but there is a couple fuses I think for spark. If those are good tjen check ur ignitor and coil. If those check good check the voltage going into the dizzy if no voltage there then keep tracing back till u get voltage to ur dizzy
If u don't got a helms then search for the wiring diagrams here on ht

No blown fuse and power to dizzy.
I did feel that the turbo timer might be causing a prob so I uninstalled it all together.
