I just don't know, drove my 850 turbo getting food, went back home, then woke up for work and the car won't start. I've changed the cam sensor, crank position sensor, all the injectors are working, I have spark in all the plugs but it just won't start.

The only codes I had were throttle position sensor, wastegate valve "low"

I don't know how those are related. I don't know what else I can do. I know for sure I didn't touch timing

 

Had a similar issue recently on my 1993 850...Distributor Cap "scored" with carbon tracks inside, 2nd time it has happened. Once Cap is "scored" the spark will try to follow the tracks causing rough idle or won't start. For some reason there was moisture in the Cap so replaced it & started right up. Also, it had the original Ignition Coil so decided to replace it too.

 

how did you test for spark? did you measure fuel pressure? you should have about 40 PSI at the rail. Not uncommon for a fuel pump that is drawing too much current (something to measure) to take out the FPR on these cars, so you can jumper the relay to build pressure at the rail to give it a go. When you say the injectors are working - how so? If you are getting squirt and as you stated you have spark, it should fire up at least to a sputter. Did you pull a plug to see if its wet or oily?

So after messing around I disconnected the cam sensor and then reconnected it, it actually fired up, but a new problem arose now and now the car won't pass 2000 Rpm. I would say it's a limp mode, and with the code of p0245 which is still the engine wastewater valve low. Would that be a cause of the limp mode?

 

P0245 is the TCV (turbo control valve) signal too low.
