Cranks but does not start?

Hi,

In most cases, this is the result of either a fuel issue or an ignition issue. Let's start with that to narrow things down.

Here is what I need you to try. See if the engine starts for a couple of seconds using starting fluid. If it does and then stalls, we'll know its fuel related. If there is no change, then we need to check for an ignition spark to the plugs.

Here is a link that explains how to test for spark:

Try this and let me know the results. Also, if you have a scan tool, see if there are any diagnostic trouble codes stored that may point us in the right direction.

Take care,

Joe

I checked and don't see a spark between the plug wire and a wire attached to the battery ground.

Hi Danny, the first suspect when a no spark condition is present is the crankshaft position sensor. Replacement requires the timing belt cover to be removed, so we need to check a bit more to confirm.

The easiest thing to do is check for an RPM signal using a live data scan tool. I don't know if you have one or access to one. If you do, try that and let me know the result.

If you don't have a scan tool, check the tachometer to see if it moves a little when cranking.

Take a look at this link. You may find it of interest. Also, I attached a pic below showing the crankshaft position sensor's location.

Also, if you can record it cranking and upload it for me to hear, that may be very helpful. We could even have a broken timing belt.

Let me know.

The tachometer needle doesn't move when the engine cranks. I tried to upload an MP3 sound file, but the site doesn't allow that file format. When I try a video, it keeps stopping during upload. I think it's too big.

Looks like it finally uploaded.

Hi,

I listened to the recording, and the timing sounds good. If the tachometer isn't moving, my first suspect is the crankshaft position sensor. Take a look at this link. It explains symptoms and causes related to sensor issues.

If you look below, I attached the directions specific to this vehicle for replacement. I suspect this is the cause, but I can't be 100% sure. If you feel the same after reviewing the article, I would replace it.

Let me know your thoughts or if you have other questions.

Take care,

Joe

I tried another test. I removed the air filter and bought some carb spray. The car started and ran for a few seconds so it seems to be related to the fuel delivery system.

What would you suggest I look for on that path?

FYI, it seemed to run smoothly when it did start. No misfire or rough running.

Hi,

I agree. Its fuel related. What I would do is first check to see if there is any fuel pressure at the fuel rail.

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

If there is no pressure, we need to check if there is power to the fuel pump along with a ground.

If you look below, I attached the directions to check for power and ground. It requires a little work on the carpet (cutting it). Do not cut it out completely. Only make it into a flap that you can open and close. Use a new blade in a utility knife. Also, there is wiring under the carpet, so you need to be really careful not to cut into them.

Let me know what you find.
