Trans tech stated crankshaft position sensor need changing(he changed solenoids in trans). Crank for a week. Then no start. Changed out the sensor. Started twice. Back to cranks/no start. Plenty fuel. No spark out of coil. Dkgrn/or wire to coil-no power. Switched asd relays w/other good relays. Had power to coil. Cranked twice then no crank. Repeated this process several times. For whatever reason asd works, then don't. Is this only one(asd) supplies power to coil? Thx.

Any applicable trouble codes? The computer has to see both the cam and crank sensor signal or it won't ground the asd relay. You might try unplugging the 02 sensors, see if it helps anything? When the problem is ongoing, did you try checking voltage and ground at the coil side of asd relay?

No codes. Asd clicks. What do you mean checking voltage& ground side of asd relay: remove relay check socket it came out of?

I'd fix it correctly. If something wrong with 02 sensor or wiring circuit, fix it.
