Hi, I have changed the crankshaft sensor, but it is still the same problem. The engine check light is not coming on.

Hi,

When this happens, it is usually either a loss of ignition spark that is lost or fuel. Do me a favor. See if the engine starts for a couple of seconds using starting fluid. If it does and then stalls, we will know its fuel related. If there is no change, then I need you to check for ignition spark to the plugs.

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

Let me know what you find. Also, is the mileage you listed the actual mileage on the engine?

Take care,

Joe

I have tested the coils they are not sparking all four of them, and I have changed the crankshaft sensor.

Hi,

Next, at each ignition coil connector, there will be a yellow wire. Check each one for power with the key in the run position. If each one shows power, check the white wire with a black tracer for continuity to ground.

If there is no power, I need you to check three fuses and a relay. If you look at pics 3 and 4, I highlighted the ones to check. Pic 3 is under the hood and pic 4 is in the vehicle.

When you check these fuses, it's important to make sure there is power to them as well as confirm the fuse is good. Here is a link that you may find helpful:

As far as the relay is concerned, switch it with a different one in the box that has the same part number. If there isn't one, here is a link that explains how to test the relay:

Let me know what you find.

Take care,
