No fire to plugs.
Has been driving fine just a little miss at low rpm.
But now can not get no fire to plugs,checked the
control modual and is fine. Put new plugs and plug
wires are bout year old. Checked all the fuses,What
step should I take next? I'm on a very low budget
Your car has a distributorless ignition system, therefore there are sensors in the engine that detect crankshaft and camshaft positions. The crank sensor tells the computer where top dead center is, and thus what cylinder is next to fire through the coil pack. The cam sensor accordingly helps the computer run the fuel injectors. In short, a diagnostic test through a GM Tech II type device should be considered to confirm or rule out sensor failure.
