Car will not start. Please help!!!!!

[spook302]

Ok lets try this again. I woke up thursday and my 91 gsx would not start.
Here are all the things I have checked........

Spark- I have spark to all the plugs, plugs are dry when I pull them out after trying to start.

Fuel- I have plenty of fuel pressure..... I just checked it ten minutes ago....

Injectors- just put a noid light on them and they are indeed firing....

Timing belt- Is brand new along with everything else on the car since this summer... It is in time.

grounds- all look good and are tight and non coroded.

Compression- is good on the car.... pretty fresh engine.

I have the three major things needed to run the car...... so why wont it start?

All fuses are good. Relays all good. I can spray starting fluid in it and it will start. That is ecxacly why I thought fuel issue.

Now here is were it gets dumb. I was able to start the car last night. I had been attempting to spray starting fluid into the intake to see if it would start. It would fire up kinda but That is because I wasnt getting enough into the intake for it to fully run. So I say to myself there is a fuel issue. The pump in the tank is only 7000 miles old. It does cycle and Like I said I have plenty of fuel pressure at the rail. Right now I have capped the return line off. I know this will create a rich condition. I cranked the car over for ten seconds, pulled the plugs and they are @#$%ing dry!!!! So I check the injector pulse and there it is still. I am running circles with diagnistics right now and finding not a single problem in any system but still no start. I am ready to blow my car to pieces. Soooooo pissed off right now I can explain it in words. I am a mechanic. I diagnosis no start everysingle week. I always find the problem..... I just dont know where to look anymore... Please remember that the car did start and run last night..... so whatever this problem is it is intermittent.

Also some ahole stole my pda out of the car. Didnt take the charger the pen or anything. So icannot check the ecu for stored codes at the moment. Can I use the software through my laptop? Can I plug my laptop into the car to check for codes without the pda? I need to get one again but I am not buying any extras for the car till the damn thingstops being a pain in my ass

Coolant temp sensor can cause a no start or hard to start issuses, I just had this problem and found one of the wires going to this sensor was broke off(dry rot)so I spliced new end clips on and poof she started right up. Other problems could be the cam angle sensor as it works as the crank sensor too. Let us know what you find.

Dude. I just found my broken was digging around in my harness for a wrench I dropped. After I got the wrench is when I clamped the return line shut to see about the regulator when it started. The next day that trick would not work. So I was think about the wires I had moved around in there and that I must have moved something by accident that contacted eachother and let the car start. I am looking for my connectors and going outside. I will post in the next couple minutes what happens.

Ok it took me a bit to find my electrical connectors. I found them. Put them on. IT RUNS! I cant believe it was so simple compared to what may have been wrong. I looked in all the wrong places first. But I checked everything I would on any car. Fuel, spark, leaks, pressure etc....... I didnt think that no reading from the coolant temp sensor would not let the car start at all. Not even a puff of smoke or attempt to start. Just nothing. These cars are really touchy. But I am back on the road. That wire must have been hanging from a strand because the ar has never started up that well especially after sitting for 5 days. It starts great idles high for a second then drops down where it should be. I am soooooooo happy I finally found this stupid problem.
