Engine wont start!

This sounds like the crankshaft angle sensor needs to be replaced but to be sure here is a guide we can use to pinpoint the problem.

Please run down this guide and report back.

I checked the fuel pressure with the gauge. The gauge read 40-45 psi. It couldn't be the fuel pump if the sparkplugs aren't firing.

Are you saying that you do not have fire?

No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it

Just picked up a 1999 Grand prix GT. It wont start, was told by previous owner that starter was bad, I had the starter checked, was told it was good, I was also told the Ignition switch/lock cylinder was bad and replaced it, when I try to start the car the dash lights work, but every thing else does not, no head lights. Ect. The starter just clicks, and no power any where. Any help would be great.

Check to make sure the battery is good. If you only get one click from the starter, it does sound bad. I would remove it and have it bench tested, but not until the battery and all connections are checked.

Thanks The battery is new and was also tested, and the starter clicks 4 to 5 times, I am thinking maybe the netural safty switch or elec, switch in steering column. Would a obii scan test indicate if these switchs are working

It sounds like either a bad starter or a weak connection. The clicking usually indicates a weak battery. Since it is new, I would be looking for bad connections or corrosion. Even a loose battery terminal can cause it. How was the starter tested?

IT was bench tested at an autozone. Battery is about two weeks old. We also ck and cleaned battery terminals and all connections at the starter, and cleaned mounting surfaces of block and starter to make sure there was a good ground.

That is interesting. If you are getting clicking, then the starter is getting power. Do me a favor. Have a helper turn the key to the start position while you check for voltage to the smaller wire at the starter. You should have 12v. If you do, try running a new ground directly to the battery. If that doesn't help, replace the starter.

Thanks I will try that and post the results in a day or so. Thanks again.

I drove my car the night before and got up the next morning and now it won't start. I changed the fuel pump and all the fuses and relays and it still wont start. I also found some burned wires under my battery and replaced them and still no start. The engine tries to start but will not turnover. I have already spent $300 on this problem and I am becoming desperate for an answer. I have changed the fuel pressure regulator and the mass airflow sensor and I have no fuel pressure. If anyone could help I would greatly appreciate it.

Do you hear the fuel pump when key at run position?

You replaced the fuel pump and there's no pressure-check the fuel pressure to rule out the pump and also check for injection pulses.

Let me know

No, I don't hear the fuel pump when I turn the key. I'll check injection pulses. Thanks for tip.

Check the fuel pump fuse and relay

Belt broke, replaced belt, now wont start

Maybe the belt hit something when it broke? Do you have a crank sensor around the harmonic balancer? Have a helper crank it while you visually check for spark at the plugs. If that checks out, use a gage and check fuel pressure. Do you have compression, although my info shows that belt to be accessory belt, not valve timing.

Checked fuses, has no spark. Still has fuel pressure

Some fuel pressure may not mean much, if that is the initial prime? Post the vin, please. I'm not sure of engine litre size?
