Engine will not start, cranks, have fuel pressure 52 psi, have good spark, replaced distributor. I believe it is a security problem. Horn and lights go off last few months for no reason (have tried all resets I can find from web) or think maybe crank sensor? Help please.
Do you
have the same problem?

Welcome to 2CarPros.

If you have spark and fuel, the crank sensor is good and the security isn't turning it off. Have you checked for an injector pulse? Follow this link:

I don't know if you need it, but here are a few links you may find helpful when checking wiring, electrical, and other ignition related issues:

If you can, see if it starts for a couple seconds using starting fluid and let me know the results. If it does, then it's fuel related. If it still won't fire, then it's ignition related.

Let me know.

Hello Joe: Thanks for the reply, sorry for wait, have a few things going on here. Anyway my bad I think, the car did start in the parking lot, (where it had failed), and at that time I checked spark, and had a yellow looking, but strong spark, and the car did restart and run about ten seconds, towed it home, later checked fuel press. Had 52 psi at rail, (i then thought it was either a cam sensor or crank sensor, so replaced distributor, and after your note, I sprayed starting fluid (and I knew it was going to run, but nothing. I sprayed again, nothing, so checked spark, nothing. PS. Checked all fuses, and all types reset for security system, etc, nothing, this is my daughters car, I am 77 had a brain stroke, (so kind of slow), but have always repaired my stuff my self (if possible) could it be the crank sensor keeping no spark? Or the security system. Thanks for any information and help. P/S I don't have a noid light set, could not find for this car, also working alone, but know how to use a vom, well. Also can't I jump the relay to start car at the engine.

Welcome back:

Interesting, I just came home from Cleveland for my wife. She has a brain tumor. Some days I question why I wake up, but God keeps us around for something.

As far as the no spark, if it won't start with starting fluid, the crank sensor is my first guess. No need for a node light.

Here are directions for testing the sensor. Basically, you are just checking for resistance. Also, I bet if you pull a plug, it will be wet.

CRANKSHAFT POSITION SENSOR
COMPONENT INSPECTION
1. Disconnect crankshaft position sensor (OBD) harness connector.
2. Loosen the fixing bolt of the sensor.
3. Remove the sensor.

Picture 1

4. Visually check the sensor for chipping.

Picture 2

5. Check resistance as shown in the figure.

Resistance: Approximately 432 - 528 Ohms [at 25 C (77 F)]

If NG, replace crankshaft position sensor (OBD).

Also, pictures 3 and 4 are for location of the sensor.

Let me know what you find.

Joe
