Cranks does not start

Hello,

This could be a problem with your vehicle's Crankshaft Position Sensor (CKP). This sensor provides the Power-train Control Module (PCM) a signal with where the engine is in it's 4 stroke cycle. The PCM, or "computer", uses this signal to make the spark plugs spark, and make the fuel injectors work. In the diagrams down below I have not only given you the factory guide for troubleshooting the CKP, but instructions for the removal and installation of the CKP as well, in case the tests show the CKP to be bad. Please go through these guides and get back to us with what you are able to find out.

Thanks,

Hi there, did you receive my reply on this? the crankshaft position sensor read 1176 ohms. still no spark.

Hello again,

Okay, the resistance is in specs, so the sensor itself looks good. Let's look at the delivery system. In the diagrams down below I have include the wiring diagrams of the CKP circuit for your vehicle, as well as instructions for how to inspect electrical connectors and how to test for unwanted resistance in an electrical circuit using the voltage drop method, which is the preferred method for doing this. Please inspect the two CKP wires and the connectors at the CKP sensor and the ECM connector as well and get back to us with what you are able to find out.

Thanks,

ok heres what i found, no power at the connector to ckp. does the key have to be on?

Hello,

In order to test for voltage you will need a helper to be cranking the engine. The CKP on your vehicle is an inductive CKP and does not require an outside power source, instead it produces it's own electricity in the form of AC current. So set your DMM to AC not DC Voltage and have a helper crank the engine. If your CKP is working it should produce between 1-3V AC at startup. I have also included a few more factory diagnostic tests to see if your CKP is working in the diagrams down below as well. Please go through the guide and get back to us with what you are able to find out.

Thanks,

i have voltage at connector, got spark at the plugs,took the fuel filter off cranked engine, and bunch of fuel came out. it starts for a second but cuts off real fast.

Hello again,

Okay, so it sounds like you might have a plugged fuel filter or a crushed fuel line or some kind of restriction going to the fuel rail. Replace the fuel filter and if that doesn't work then check the fuel line from the fuel filter to the fuel rail for any type of restriction. If none is found, then the PCM is probably going to be bad. Please check these and get back to us with what you are able to find out.

Thanks,

i forgot to mention that i tried starting fluid also. it did not start either..

Okay,

So an engine only needs three things and it has no choice but to start. They are in no particular order fuel, spark(delivered at the right time), and compression. So if you have spark at the spark plugs, and tried starting it with starting fluid, then the only thing left is compression. Here are a few links down below on compression and how to do a compression test on your vehicle:
