93 850 Wont Start


850Stud

Recommended Posts

Over the winter I started having problems with the car starting which I guess lead up to this. I'd turn the key and the car wouldn't crank, turn it again and it would crank kinda rough then start up.

I'm really stumped right now and this thread is my last resort before i just bring it to a shop. Ive searched other threads but to no avail :( .

The car cranks but wont start up . Fuel is getting to engine. Changed the plugs,cap/rotor and wires. Swapped out the fuel injection relay. I also replaced the camshaft sensor a week ago with a used one from a C70 and the car actually started up, but died a mile later and started up twice but the engine turned off a min later each time just enough to get me home.

Any help would be greatly appreciated. :)

Thanks!

I just had the same problem a few weeks ago, out of no where my car wouldnt start, tried it again a few minutes later and roughly it got going. I then went to Advance Auto to have my battery checked...voltage/alt. OK. I then went home, next morning I found it wouldnt start at all. AAA came out and I had 68 cold cranking amps out of 600...might wanna check your CCA's. I'm no master mechanic...just thought I'd share that.

Good luck. :)

ps you can have proper voltage and insufficient CCA's as I did

I agree. Have the battery load tested. Also check with a battery hydrometer and make sure the cells are good.

What about spark? Are you getting a good spark? Is there a white chalky film around the coil? More like along the aluminum bracket directly along the coil. You could be having a strong intermittent ignition failure from the coil.

Starter load test wouldn't be bad either.

Check and make sure the crank sensor is good to but I would do the other things first.

The coil is fine i swapped it out and tried it on my other car and it started up fine. The positive connector of my battery though gets that weird whitish/blue fuzz though when I put it in that car.

Also idk if this will help, but the little red wire that goes with the larger positive battery wire once wasn't connected the other day when i tried starting it but once connected it started up. The other times though it didn't help.....
