We have been troubleshooting an intermittent no start condition on our car and have determined that the issue is we have no injector pulse (we have injector power as well as spark plug spark). We are at the stage where we would like to check the crankcase position sensor, but this is where we need some clarification on this year/make vehicle. When we look up this part (or if we have an auto parts store look it up) we get the part shown in the attached picture who's location should be the same as in the picture of the 1997 Accord (attached). When we get under the car and look for the wiring harness that should be coming from the crank case cover, we see none. If we consult the Haynes manual and the wiring diagrams it says "Not possible to include all wiring diagrams for all years. These are the typical and most common." and then shows that this model "should" have three sensors (CKP, TDC, and CYP) in the distributor (and does not address the crankshaft). An inspection of the distributor shows that these three sensors are present, and they each ohm out at 800 ohms, which is in the acceptable range. My questions are: 1) Since I have the three sensors in the distributor, does that mean that there is no additional crankshaft sensor in this car, like in the attached pictures? 2) If it turns out that this car does have the additional crankshaft sensor, how can we locate the wiring harness to test it without having to pull the front cover? 3) Once we test the sensors in the distributor for proper output (and crankshaft sensor if it exists), if they are good where would you suggest we look next?
