car won't start/stalling while driving

long story short…

  1. car wouldnt start all of a sudden
    • car was running fine with no mechanical problems before
    • just drove the car the night before, but now it won’t start
  2. waited a few hours (bout 8hrs), then car started
    • once it started, the RPM was dropping really fast, so i gased it (about 2k) to keep the car from stalling
    • LOTS of blue smoke coming out
    • car idled fine after
    • shutoff car, started it again to make sure, started fine
  3. next morning getting ready to take car to shop
    • car wouldnt start again (after repeated attempts)
    • made call to shop to let them know i couldnt make it down 2day, then i heard a REALLY LOUD HISS from the engine
  4. gut feeling told me to try starting it again
    • it started
    • again, it idled funny for about a minute, but no blue smoke
  5. shop took a look at it
    • of course, the car had no problems starting/idleing while in the shop
    • they did a compression test - passed
    • checked valve seals - passed
    • head gasket - passed
    • checked Distributor - needed cleaning, so they cleaned it
  6. took car home, no problems
  7. next day, the car stalled while driving…again, this was out of nowhere (it was running fine, til it stalled again)
  8. now i’m stuck…what else could it be??

i’m basically taking the car back again, i wanna make a list of things they should check (it’s all free, cuz they are doing this as a workmanship warranty when they rebuilt my motor)

couple things u guyz should know first:

  1. the car is not driven hard at all!
  2. the car was not driven hard for about 7 days prior to troubles
  3. mechanic believes its an electrical/sensor problem
  4. already going to get ignitor checked out

this is what i have done:
MSD 6A
MSD blaster coil
MSD distributor cap
MSD 8.5mm magnacore wires
1 yr old distributor (recently replaced)
AEM CAI
header
exhaust
crower 403 cams
crower titanium valve springs
crower titanium retainers
minor p&p
thinner head gasket
chipped & tuned ECU (8K redline)
high flow cat
umm…i think thats it…i forgot what else there is…lol
everything else is cosmetic…

thnx for reading this LONG post

and thnx in advance for any help…

longshot but maybe the fule pump or filter

You know what, might even be ur ecu. My friend, his car would die while driving. He would then proceed to take out the ecu, slap it a couple times, and then the car would start again.

I had those same problems when my main relay went out. I would get a helms and check the main relay. It definately is something electric.
