The car will not start. there is no problems with cranking or firing. I believe it to be a fuel issue, but the fuel pump is running fine and building good pressure. I have cleaned the carburetor and throttle body along with the fuel injector. It seems to be be getting enough gas, but will not crank which leads me to believe it may be a sensor problem.

In the column to the right of your question, are a couple of titles for, not starting, and engine will not start, a lot of good information, also repairs guides link at the top of page.

Engine cranking, did you visually check for spark at the spark plugs? I know your talking about fuel, but, could be more than one issue. Did you use a gauge and check proper fuel pressure? Can you check voltage and ground for fuel injector? If more than one issue, I want to check for rpm signal, comes from crank sensor through the ignition module to ECM. The info I looked at was for 2.5L engine, didn't see 2.3L. On the 2.5L engine, the crank sensor shows to located under the ignition module which is under the coil pack.
At the moment, I cannot be positive what is wrong?
Are there any applicable trouble codes? Your obd1, you should be able to check some codes, yourself, if there are any.
