I have spark at the coil going to the distrubater,but no spark at the plugs. and no power at the injectors


CKP. Cam Position Sensor. Needs crank and cam sensor signal to work. Need codes pulled at diagnostic port on front fender.

Google 'Volvo Code pulling'' or similar, for sites explaining how to pull codes without a scanner.

The sensor in the bell housing goes bad too.

Check your fuel pressure to ensure proper pressure to the block, also did you replace the fuel filter.

On a side note: 3 things a automobile needs to run

AIR-make sure you have a clean air filter and your MAF (mass air flow sensor is plugged in) if you pulled your breather to innspect anything, there is a possibility that it came unplugged or you unpluged it and forgot to hook it back up, a car wont start without it being plugged in if equiped

SPARK-Make sure your car has juice to the plugs, if the plug doesnt fire the car wont run, if you have to pull each plug and ground them to the engine block to see if they arch. If not trace the problem down (if you changed the fuel pump you have some mechanical skill and should be able to troubleshoot a spark issue)

FUEL-Check for proper pressure, dirty fuel filter(s) and if your system has a return line, make sure your hoses didnt get crossed cause this will damage the engine and regulator.

Hope this helps Thanks for using Fixya.com

No fire from ingition coil


are you saying that you have 12 volts to the coil but no spark out/if this is the case first make sure the cam is turning by looking in the oil cap hole,next yes the cam sensor is a common failed part and can cause the problem, you also have the crank sensor just below that and it would not hurt to replace also
