1995 Chevrolet Caprice Q&A
1995 Chevrolet Caprice Question: Ignition just stopped
At a light and car just shuts off. Discovered I've got no spark. Replaced distributor, coil, control module, and wires. Still no change. I noticed that a fuse is burning out so I replaced that too. Once replaced, turned over the engine, it blew again. What should I check next. Please reply before I pull all my hair out. - RACERX_1
You need a wiring diagram to trace down all the circuits for that fuse, and then you need to check each device and circuit until you find the short or over load which is blowing the fuse. It is not easy but this is the way you approach a fuse blowing that in some way controls how/if the engine runs. which fuse is it? Can you determine that. It should say somewhere on the panel. The most reliable place for a quality schematic is www.alldatadiy.com Good work! I would check the Ignition switch and circuits. If the PCM ( engine computer) were ruined, I doubt that the car would ever start. I have seen wires that were chafed and touching metal in the ignition circuits. Wires that even go to the distributor etc. If you can disconnect parts of the Ignition circuits, that may help. Even some of the lighting circuits can be energized by the Ignition circuits, so a broken bulb, can , in some cases, cause fuses to blow. The most reliable place for a quality schematic is www.alldatadiy.com You have to pay a fee for the info, but Alldata is a professional level data system ( I use it and Mitchell every day) for repairing cars. Be sure to print all or even more than you need once you pay the fee. Print out all the schematics if you can and parts location info for any thing electrical or engine power train related ( i.e. fuel njection, ignition etc ) Good Luck, let me know how you make out. - dandd
Finally got a chance to change the ignition switch which I thought might do the trick. It was a no go. Where can I acquire a electrical schematic for this type of car? - RACERX_1
On cold starts, the car is fine in the idleing, or park position, but when I drive it before letting it heat up there is a knocking/grinding noise coming from the rear of the car. The more I drive ...
