Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name isCustomerand I can assist you with your question. The Crank sensor is located Lower Front RH Corner Of Engine by the ignition coil packs and module. You have to gain access to it from underneath. However, if the engine has spark, the crank sensor should be good. Does the engine run on starting fluid?
If the ignition and valve timing are both in time, then the engine should start and run on starting fluid. If not, and your SURE that the engine has spark, then the engine is out of time. I would then start by checking engine compression and the timing chain marks to ensure they are lined up properly.
However, if the engine does run on starting fluid, it is possible that you have low/no fuel pressure, bad gas or no injector pulse. You can check injector pulse using a noid light. Here is a link to a noid light set for only 10 bucks.
I am going to get some sleep. Please run these tests/checks and let me know. I will be on line tomorrow. Talk to you then.
Sorry, the noid light set is 20 bucks. Still a very good deal!! Talk to you in the morning.
