Car shut off while driving, has not started since?

Hi,

If the tachometer isn't moving, you may have gotten a faulty crankshaft position sensor. Do me a favor. See if the engine will start if you use starting fluid. If it does and then stalls, we know its fuel related. If there is no change, it's likely an ignition issue (CKP). In this case, check to see if there is spark to the plugs.

Here is a link that explains how it's done:

Let me know. Also, let me know if you used a factory crankshaft position sensor.

Take care,

Joe

Steve,

If there is no movement in the tachometer when cranking the engine, that is usually the result of a faulty crankshaft position sensor. If you have a live data scanner, see if there is an RPM signal when cranking the engine. If there isn't we need to go back to the CKP.

As far as the coils are concerned, I would think all would fail at the same time. If there was no change when you used starting fluid, none of them were getting spark.

Here is what I recommend: Before even checking the CKP, let's first determine if there is power to the coils. At each coil, there are 4 wires. Each connector will have a black wire with a white tracer. With the key on, check to see if they have power. If they do, we need to check the ground.

The ground for each coil is a common ground. They all use the same one. So, at each coil, locate the white wire with a black tracer. With the key off, check if there is continuity to ground. If we have both power and ground, either the CKP is bad, or the ECM has failed. I will explain how to check that once we get past this issue.

Additionally, we have relays to contend with. If there is no power to the coils, check the fuses I highlighted in the attached pic. (pic 2). If the fuses are good and we have no power at the coils, we need to check the relays and the relay circuits.

Here is a link that shows how that is done:

I attached two pics below. In pic 2, the fuse box is under the hood except for the IG2 fuse (10 amp). It is in the driver's side interior fuse box behind the dash.

When you check the fuses (especially the one in the vehicle) even if the fuse is good, confirm there is power to it. The key will need to be in the run position for that fuse to have power.

Let me know what you find.

Take care,

Joe
