So I bought a turboed 420A RS. Its been fine for months. Now all of a sudden it starts when its cold, then once it warms up it dies. I left it in the garage over night and it won't even start, push it out and let it cool and it starts then dies after 5 min.

-when it dies it doesn't misfire or stumble, dies as if key was shut off

-fuel pump and ASD relays click and turn back on after it dies, sometimes restarts, but if so it will die again in a couple minutes and then not at all

-after it dies finally, fuel and ASD do not click at all when cranking

-I have no spark out of coil.

I have checked continuity for both signal wires from ECU to fuel and ASD relays as well as to crank and cam sensors. I took the computer and put it outside and left the car inside and even with a cold computer it still doesn't start. tried the same with the cam and crank sensors and it didn't start.

Please help
 
Check connections and battery? Does it loose charge, or if you let it cool will it start like nothings wrong again?
 
Once it cools it starts like its brand new. And when it dies its instantaneous, no sputtering or anything. I haven't had a voltmeter on the battery when it happens. I'll test that out in the morning and report back. I tested the coil connector with a test light and I'm not getting a pulse when cranking either. Even if I manually jump and activate both fuel pump and ASD relays, I still get no spark.
 
Ok, so I've been trying for days, but now it won't start at all, just cranks with no spark and fuel/asd relays not energized. Anyone run into this before.
