I can't get my 1992 Chev S10 2.5 liter to fire. What could be the problem?
It could be alot of things but I would try one thing at a time starting with the coil wire, then the cap and rotor. It could be the coil itself. If you havent worked on it before it happened then it is probably the ignition module inside the cap. It has a spark control and a knock sensor among other things that have alot to do with the spark. Theres a pick-up coil in the distributer that sometimes shorts out. But vary rarely. If you have a multi meter and some time there are tests to check out everything. You need to go in a line backwards so that you can run the problem down. Pull a plug and plug it in to the wire and set the bottom of the plug on something metal on the engine, spin the engine over and look for it to spark against the metal. Just be super careful because a spark needs a drop of gas , to BOOM you get to learn how to stop a fire. That kinda tells you if the plug is good. Then pull the plug off and stick a nail in the wire and ground the nail and spin it and see if you get a spark if not then move up to the coil wire. And so on and so on until you find a spark. If you have a test light check to see if you get power to the distributer , if you do and it wont spark then its most likely the ignition modual.
