I recently purchased a 2001 Volvo S80. It has had a hard start from the second I purchased it, but being as though I am pretty savvy with cars I assumed a good tune would fix it. Well before I could even get to performing a tune up, the car decided it no longer wants to start. Since then I have checked codes and got a p0717 "Transmission related code" I pulled the etm out and cleaned it. within the etm itself was a mess of motor oil which I cleaned out, not sure how oil ended up inside of it? The etm has a yellow sticker from 2005. I replaced spark plugs and checked spark which checked out good. Fuel pressure jumps to a little over 50 psi when priming. I replaced the battery which was still under warranty. I have checked every relay with a external 12v battery and can hear each one click. Starter works well and cranks hard. I have checked all grounds and fuses. Timing belt looks good. Now for the weird part, when I go to put the car in the ON position immediately the etm will start clicking constantly and the fuel injectors also start to spray as well as a clicking sound from fuel pump relay. Also the tach jumps up and down with the key switched to the on position. If I crank the car for over 6 seconds I will always get a backfire from the intake. This car has me so confused and all the shops I call do not want to work on Volvos. The car only has 101,000 miles on it and everything looks in great condition. Thank you so much for your help
