2. look over the engine while running listen for hiss to find vac leak and look for sparks around plugs and distributor
3. turn off
4. plug vac back in and check both ends of the plug wires so there snug

Hope this helps Mike

It should be located on the drivers side left of the steering column as sitting in the vehicle. It is normally attached to a spring clip.

Use a ratchet with the correct socket. You will probably also need an extension to reach the bolt.

Could be clogged fuel filter or bad fuel pump.

The voltage for fuel injectors go hot with the key on. The computer switches the ground on and off, check voltage and ground. If the computer doesn't ground the fuel injectors, you'll have voltage on both legs. If computer doesn't see rpm signal, it won't ground the fuel injectors. If no rpm signal check the crank sensor and ignition module, plus wiring circuits. Don't replace anything unless your testing points in that direction.
