Car won't start after replacing spark plugs!

Hi everyone,

I have 1999 Volvo S70 T5.

Yesterday, I decided to replace the spark plugs on my car with new OEM plugs. When I was all finished, I tried to start the car. The car cranks but doesn't start. I made sure all the connections were ok and correct. Today I checked to see if there is spark, and there was none. What else could I check?

I'm getting really frustrated! I took out the Camshaft position sensor wire, but I'm not sure if it's bad. Is there a way to test it?

Any help would be greatly appreciated!!!

If the car ran fine before you did the plugs, then there is something up with the install. I would first make sure you have spark at the coil and work your way to the plugs. If you don't have spark at the coil, then I will look into sensors and the like.

There's apparently an incorrect diagram about which distributor terminals go to which plugs in a Haynes manual...

I'm pretty sure there is no spark. I attached one ignition coil to a spark plug and ground it while my friend attempted to start the car and did not see a spark. I also sprayed started fluid, and the car only cranked. This led me to believe that there is no spark. I put the old plugs back in and tried to start; no luck. I did one plug at a time and never disconnected an ignition coil, so there's no way I mixed those up. BTW, all ignition coils are less than 2 months old, so the chance of them going bad is slim to none. I am pulling two codes right now, p1113 and p0013. One of them is camshaft related which made me think that it might be the cam position sensor . . .

1999 has no cap/rotor.
1999 uses coil pack.

Check the wirings.

Will I find the coil pack by tracing the wire up from an ignition coil?

There is no "ignition coil" on a 99.

I'm gonna cut and paste something I've written before, so it's a little repetitive, but gives you the values you need to look for from the sensors:

The crankshaft sensor is located just above the transmission housing; the camshaft position sensor is in a housing just behind the distributor cap on the engine block. You should see >200 ohms on the crankshaft position sensor, and often times the cam sensor will set a code. Pin 1 to 3 of the camshaft sensor should read 12.5 V, 1 to 2 should read <5 V, and pin 1 should ohm out 0 resistance to ground.

I'm a 100% positive that there are ignition coil. Here is a link for what I bought and installed:

I am going outside to check the camshaft now. I'm assuming the ignition should be on. Is that correct?

Yes, ignition on. Sorry for the confusion, I meant they don't have a "single" coil like models like mine do, yours has an individual coil/"coil pack" for each cylinders. It still has to make a spark somehow, this way is just more efficient

This info from 2001 V70 T5 may help you:

Is battery fully charged?
