I Have A 1993 Volvo 850 Turbo I'm Working On In Automotive Tech Class, I Swaped A New Engine In And Connected Everything And Tried To Start It But it Just Turns Over It has no spark or injector pulse, I checked and the fuel pump I Checked The Crank Position Sensor with a multi meter and it works got a new camshaft position sensor still does the same thing and doesn't start I made sure and everything is working I used the A/B box and scanned for codes but A2 Fuel System and A6 Ignition System Doesn't Want To Work It Doesn't Want Blink At All It Just lightly Glow And I Know It's Supposed To Blink 111 if I doesn't work at all so I don't know what could be wrong do you guys think it could be the computer or something?

 

Anybody?

 

Could be the ECU (computer), but it could be lots of different things. You won't see injector pulses unless you have spark, so go after that issue first.

BTW: you will get much more in the way of response if you post in the 850 section..

Also; hopefully this is not your car? the '93 was the first MY of the 850 and had lots of odd issues which were resolved with the 94 MY and later.. i.e. I would not invest much $$ in it..
