Post PCV replacement problem - electrical issues

Hi,

I recently bought a 850 t5r (love it) with smoke coming out the dipstick, suspecting a clogged pcv system. I have no prior experience with servicing cars, but I decided this would be good time getting some, as I found a lot of support on internet on this topic. I have changed the pcv system and cleaned the ptc and today I managed to put everything back together. When I hooked up the battery, I tried to start the engine but nothing happened. Symptoms are

- Warning lights do not go on
- There is no info from the computer on the dash
- I did not hear the gas pump working
- The starting engine didn't start

Other electrics do works: the clock is working on the dash, headlights turn on, interior lamps work, radio works. So it seems it's specific to the engine bay, I figure.

I checked whether I connected the connections I disconnected during the service (on the ptc, the idle valve, and the other one underneath that one) and they seem fine. What could be the problem? Could use any suggestion, as I have only little experience..

Check all your fuses first. Make sure the terminals are correct on the battery hookup (+/-) If all of that is good, the battery could just need a jump if it sat a while.

Well done for tackling this as it can be a tricky and frustrating!

splattj has already suggested the obvious, check the battery is not flat.

If it is good or has more then 10V you should at least have the warning lights on the dash with the key in POS II. If nothing, then ensure the battery is hooked up correctly. -ve (blue or black cable) should be closest to the LH inner fender and +ve (red cable) at the radiator end. Car may not start with this low a voltage but should at least light up the warning lights.

Remove the -ve cable and make sure the cable clamp and battery post is clean. With this still removed, do the same for the +ve side.

Did you disconnect any of the cables to the starter or alternator? Make sure they are re-fitted correctly if you did. The starter one should have the cable(s) exiting straight down.

Neil.

I would suggest retracing all of your steps as took it apart and put it back together. I usually make a list for just such a purpose.
