Thank you for asking your question on Just Answer.
From your discription this sounds like a drop in fuel pressure. I would start with replacing the fuel filter if you havnt already done so.
There is an access hole under your rear seat.
Run this test for a no spark condiation,
Check to make sure the two wire connector for the distributor is not swapped with the 2 wire connector for the Crankshaft Position (CKP) sensor (usually occurs after engine work has been performed). The CKP sensor wire colors are White and Black. The two wire distributor connector wire colors should be Black/Red (or Black/White) and Green (or Blue). Verify battery voltage on both wires in the two wire distributor connector with it plugged in and back probing and check for a pulse on coil negative (Green or Blue wire) while cranking. . Check the voltage on the White/Black signal wire to the base of the power transistor on the end of the 6 wire distributor connector - look for 0.1 volt or less key on and about 0.4 - 0.6 volts cranking - no scope available. . Verify the power transistor ground is good on the Black wire in the 6 wire distributor connector next to the White/Black wire - look for 0.05 volts or less key on and cranking.
The coil is built into the dist see the picture Im sending.
Verify battery voltage on the two Red wires at the Canister Purge Volume Control Valve (CPVCV).
With the CPVCV unplugged, check resistance of the windings in the valve, from the center terminal in each row, to the outside terminals in each row. It should be approximately 30 ohms.
. Check continuity of the wires between the ECM and the CPVCV. Also check the wires for a short to ground.
Check the Evaporative Emission (EVAP) System Pressure Sensor voltage on the White wire. Specification is 3.3 to 3.4 volts key on engine off.
Then run the engine and see if the pressure sensor voltage drops, indicating there is purge flow occurring in the system.
. Check for a leaking CPVCV.
