Crank will not start

Thanks for your quick answer. I will check and let you know.

Some good and some not so good news. The sensors were replaced. The battery leaked. It was replaced along with wires below it that the corrosion ate up. The computer was replaced with another used one. It worked. For a week. Now we have similar problems - again. I haven't figured-out what led to the following situation - but now I can start the car, it turns on, but as soon as I let go of the gas pedal (that is, let it idle) the engine dies.
I know you are not supposed to press on the gas pedal when starting it. I do press on the gas pedal as soon as the engine starts, else it will die. When I let go of the gas pedal, the engine dies. I can smell fumes as if it had been flooded. Any thought as to what I should test or observe?
Thanks

After letting the car sit overnight, I tried to start it again and this is what happened. I started the engine, gave it a little gas for several seconds, let go and it idled ok. Smelled like rich fuel. An hour later, started the engine without giving gas and it ran nicely. An hour later started again without gas, and it would not start. Tried again with a little gas and it stayed running.
So, if it doesn't start the first time without giving it gas, then it seems to start the second time with giving a little gas. Naiive as I am, something is not regulating the flow of gas. Yes/no?

The harness has been replaced, so I was told. I'd better check how much of it was truly replaced.
I don't have the equipment to determine the codes. I'll have to ask the technician.

My timing belt was broken so we replaced it and the water pump. We were told that the valves and head gasket were fine. But it still wont start? Whats the problem what do I need to replace?

He did a compression test and said theres no compressin in bottom of the motor.
And he took them out and checked the valves

He checked them and said there not bent

Makes a weird sound when trying to start the car. I can hear the starter going but the engine won't turn over. Tried spraying starter fluid in air filter line and still could not get combustion. I heard that it could be the fuel pump, fuel filter, or even the timing. Any clues?

My car recently stalled after I stopped at a store and didnt want to start back up for a while. When I finally got it started it had an egg smell for a few seconds and then ran like garbage. I was able to get it to my house which was thankfully just up the road. It sat in the cold for about 2 weeks while I asked around to see if anyone could think of what it was. I was asked if the service engine light was blinking and if it was then it was likely that a cylinder was misfiring and maybe some oil got into the spark plugs. I opened up the hood and checked the spark plugs and saw that there was some oil in them. I soaked up as much as I could and then replaced the plugs and the plug tubes. Now the car wont start or even get jumped. It has power to the radio and the lights and does try to turn over but it just doesnt seem to be able to turn. Any ideas what it is?

Alright, ill take a look at that. I also just read online that it might even be the coolant temp sensor. This raised my eyebrows cause just before it died the temp was kind of hi and I checked the antifreeze and the reserve tank was pretty much empty. Think this could be part of the problem?

Drove the car at lunch Monday with no problem, no recent problems with starting or anything else. After work (approximately 4 hours later) I got in the car and nothing, no noises, no clicks, no lights, no hazards (didn't check to see if brake lights are working).

I walked home (I live/work in a small town and regularly walk into work; so most of my mileage is very short), came back the next day, Tuesday, and tried to jump the car after work. Still nothing. Cannot swear 100% that I had everything set up right for the jump, but I'm fairly certain I didn't botch even this simple thing. Don't remember if lights worked, but certainly no dashboard lights etc.

Wednesday, I notice that the clock is working (but showing wrong time) when I try to start at lunch. Coming back fifteen minutes later, the clock is off. I cannot say exactly what happened between those two events.

Took a quick look at the fuse box. Swapped the IGN 3(30) maxi fuse with another fuse and the EIN(10) mini fuse with a another fuse. Still nothing. (I know next to nothing about cars, but this seemed worth a shot).

I replaced the battery (it was due) approximately two months ago (late November 2009). At that time I successfully jumped the car and got it home and then successfully replaced the battery with little drama. Hope I didn't mess something up.
