2005 Pontiac sunfire
Car turns over nice, got spark and gas but doesn’t fire. Changed spark
plugs,starter,relays for crank,ignition and crank sensor
The only way you can have spark and fuel in the cylinder and have no ignition is to have the spark when the cylinder is empty of fuel. That's not a plug, relay, or sensor problem: it's most likely a timing problem. A way-off timing problem. You might have a broken timing belt/chain, or the distributor is in backwards (around 180 degrees off).
By gas do you mean it has injection pulse? Like gas is actually entering the cylinders?
This is the 2.2 liter with the ignition coil interconnect and the module that sits on top... the cam signal is created by the module from the ignition coils kv voltage to know which cylinder is on compression and which is on exhaust.. if you have no injection pulse it could be due to a faulty module or timing issue... btw this doesnt have distributor obviously
Have good fuel pressure changed out coil module still doesn’t fire when turning over serpentine belt turns but still not firing
