99 si won't turn over
Hey fellas, my brother has a problem getting the engine to turn over. When I crank it, it seems like it'll run but just dies. We've checked the tps sensor with an ohm tester and it checked out just fine ranging from .8 to 4.45 with the throttle eased open and closed . We thought it was a spark problem so we changed the plugs and cleaned out the distributor cap. We've also changed out the fuel filter thinking it was dirty or something. The fuel pump checks out just fine too. We're out of ideas. Anybody have any clue as to what could be the problem?
Have you confirmed spark with a spark tester? You can get a tester from any auto parts store. If you are not getting any spark, then check your ignition coil and igniter. These are both located inside your distributor and are a known failure point.
Get an extra spark plug w/ either the proper gap or a little bigger, insert it into a plug wire, hold the wire (w/ plug firmly inside the boot) with the plug touching the valve cover or another ground. Have someone turn it over a few times and look for spark. It may be difficult to see during the day, especially if it's a weak spark.
