Still lots of things to check here. Fuel pressure, spark, are losing contact at the ignition switch? Lot's of areas to poke into first.

also sounds like the Starter or Starter Relay failing.

Start the troubleshooting by cleaning all the electrical wiring contacts, like the two electrical Junctions at the firewall on either side of the engine, also clean the contacts at the cylinder head on the passenger side of the top and rear of the engine. There are two ground straps there that need to be shiny clean and tight. Use a brass brush to clean all connectors and surfaces.

Using heavy duty jacks and extra supporttowork under the car, (these cars are very heavy and if it falls on you you're dead for life),get under the passenger's sidewhere the engine joins the transmission, and look for a large body-to-engine Ground Strap. Remove it and clean it too, especially the contact surfaces on the body and transmission and the strap itself. also the bolts.

Also clean the two Thermal Sensor contacts/wires on top of the engine, and the battery cables. Keep the battery fully charged. Walmart sells a cheap Black & Decker Battery Maintainer, i've had great service out of it.

After all this is done, you will notice the car becomes "alive" and "peppier" electrically speaking.


If the engine dies after starting, (a very fast shut-off, as if it loses all electrical energy), then I wouldcheck the Ignition Switch as Ken said. These can be carefully disassembled and cleaned for like-new service.

Here's the servicing instructions for the Ignition Switch:
