Make sure that your fuel presure is up to at least 60 psi if not that could be your problem. If not, make sure you are getting spark, if not could be your Crank sensor or ingniton module ECM. Usually if your Engine control module wouldn't be bad because of your fuel pump is working, but may not be putting out the proper pressure for the fuel system. Fuel Pumps are a Problem with that year..

SOURCE: hard start
Its your fuel pump.I had the same plomblem not too long ago.I was spraying either in to start it.I have a 97 chevy truck witch requires 65 psi to start and 55 to run properly.You need to find out much psi you need to start it.You can probaly look in your manual or just make a few calls.My truck had 55 psi and it ran fine i just had to get it running first.Good luck.I wonder if that fuel pressure regulator was a waste of time like it was for me.

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

SOURCE: 97 Cavailer won't crank HELP!!
my next step is to MANUALLY attempt to see if this engine will turn. Disconnect battery, remove starter completely which will expose the flywheel. With a HEAVY flat blade screwdriver partially inserted by a tooth in the flywheel, exert pressure in a pivot movement trying to move the flywheel . If it doesn't move the engine is seized.

You can run down to your local auto parts store and buy a serp belt tool. Or you can take a 3/8 drive ratchet, locate the 3/8 square hole in your tensioner and put the ratchet in the hole. For more leverage I put a deep socket over the ratchet handle and put a long 3/8 extention in the deep socket. This will provide ample leverage and will save buying more tools you do not need. Simply move the tensioner to the direction that takes pressure off of the belt.
