Car not firing
Nov 7, 2019 (2 months ago)
Car turning over on key, no indication any of the cylinders are firing. Could this be a case of "total" breakdown of coil pack! No codes are showing on OBD test. Thanks.

You will have to isolate if it's a fuel or spark problem first .Amongst other possible causes could be the crank sensor .

Would like to ask, would there not be any codes relating to the failing of a crank or cam sensor present! Just purchased an OBD11 reader for this problem but, there"s no codes detected. I have a new coil pack coming hope it fixes the problem, if not, then at least i can eliminate that area. Thanks

Should normally trigger a code as should a faulty coil pack .

That"s what i would expect (a code) I have read that if even the ECM has gone down it would throw up a code and possibly go into limp mode. Will update if i get it going. Thanks

New timing belt kit was recently done 500miles or so. Hope it"s not ECU as last zafira had one go bad but, the symptoms are not the same. Could at least run engine (although would not rev up) This time car not starting. Thanks.

As suggested earlier , have you checked you are getting spark , fuel and compression ?

I have spark and 5v going to sensors on the temp sensor/cam and air flow. (Fitted new crank sensor.) Fuel pump purges and delivers. Still no start just cranks. Thanks

Just a thought, Relating to the air flow sensor and temp sensor, all being 2 wire. Should there be voltage on both wires with ignition on? Or does ECM collect the info when engine is running? Can"t help feeling it"s the ECM gone caput!!!
