Car starts fine, but stops in about three seconds. After starting about four times it will continue to run. Also, when ignition key is turned on, have to wait about four seconds while gas pump motor runs before trying to start. Please help. Thanks. Mike

My radiator cracked last week, leaked most of the coolant, and the car overheated and the engine died. I replaced the radiator and coolant, but now it won't start. It turns over, but won't start. Fuel pressure is good, no OBD codes, haven't figured out the best way to check the spark yet. Any thoughts?

Get it checked for compression. Chances are the head is warped.

I have since checked the compression, spark, and timing belt. Also, I replaced all of the spark plugs and wires. They are all good, but it still will not start. Any other ideas?

You have fuel, compression, and spark. It should start. In a perfect world anyways. Let me think on this one a little while, in the mean time, maybe someone else might have an idea on this.

Is there a way to test the crankshaft sensor without just replacing it?

Are you getting a pulse to the fuel injectors? I'm assuming you've already checked the fuel pressure at the fuel rail.

No I have not checked fuel pressure but when you take the plugs out they are soaked and I can get #3 cylieder to fire. Do not understand what fuel pulse is?

Pulse s the signal from the ECM that fires the injectors. You can check this with an ordinary incandescent test light between the 2 terminals of any injector connector while cranking. Are you sure your plugs aren't wet and fouled?

Spark plugs are brand new, they are clean except for gas and the #3 plug comes out black because it is actually firing. Would the fuel pressure pulse come up on the OBD? I was told that I need to replace the coil pack? Is there anyway to test that before I spend the money replacing a part I do not need?

Go ahead and check injector pulse. If you have pulse, then I have to say it's a problem with the coil pack. Let me know what you find.

Fighting with husband he was headed out I came out shortly after he was under my hood. I said what are you doing messing with it so I cannot go anywhere? He was like no I am just checking the oil. He put oil in it and then. I went inside like an idiot. Babysitter got dropped off I noticed my hood was open. So I closed it and sure enough car cranks but does not turn over. I know he knows how to get a car not to start a quick trick, but I do not know it. Please help

That is because there are multiple items that could be unplugged and cause it to not run.
I would look around for a disconnected wire, the fastest one would be the coil wire in the center of the distributor cap.

The picture should be the same engine with a Mazda valve cover. The items I marked are easy to pull and would stop it from running. The two on the right are the coil and distributor feeds. Those will make it crank and not run. The others are ones that will let it run but run like junk.

If you could take some pictures and load them here it might be better and faster.

Hello,

Please double check to make sure that all electrical connectors are plugged in. Specifically check the crankshaft and camshaft position sensor electrical connectors. In the diagrams down below I have included a list of all the engine management connectors for your vehicle. Please go through the guide and get back to us with what you are able to find out. We can go from there.

Thanks,
Alex
