I changed the fuel filter, oil, and transmission fluid. After putting everything back together the car will not start. It cranks and cranks and sometimes will sputter, but it will not start. I have kept on the starter for close to 30 seconds and all I get is a sputter.

Things I have checked or performed:
- The OVP 10 amp fuse is intact.
- There is spark at the spark plug end of the plug wires.
- Cleaned the spark plugs because they were fouled.
- Opened the fuel pressure regulator in and out lines and gas leaked out.
- Battery is fully charged.
- The transmission cable is connected.

I am out of ideas. Please help before my wife forces me to tow it to a shop.

Thanks, Bob.
