Engine stalls while driving?

That could be from the vacuum leak from the hose.

How does it sound other than rough idle. Does it accelerate?

Was thinking of capping line and regulator to see it that would work.

That is where I was heading.

It seems for some reason the regulator will not allow the proper pressure to build.

Put it together and see how it runs.

Vacuum line and regulator both plugged. Running at a constant 32 psi. Started off idling high. Now its dropped down on idle. But not real smooth. Can hear it pulsing, up and down and sounding like any minute it will stop and die suddenly

Was running at a constant 32 psi for about 8 -10 minutes and just shut off. Pressure dropped to 28 psi and holding. This is with the regulator and vacuum line plugged.

Okay, when it shuts off, does it start right back up? Do you think the spark may be dropping out?

See if the tachometer drops out when it stalls.

Will start right back, but ran shorter time before it shut off and unless I hook up the obd2 to it. It don't have a tachometer or rpm readout.

Okay, I am beginning to think it is a spark issue.

We have gone over so much, did you replace the crank sensor?

Roy

DESCRIPTION AND OPERATION
All functions of the ignition control module are contained in the power-train control module. The Ignition Control Module (ICM) receives the Crankshaft Position Sensor (CKP) signal from the CKP sensor. It processes the CKP signal into Profile Ignition Pickup (PIP) information and transmits it to the Power-train Control Module (PCM). The PCM processes the PIP signal along with signals received from the Throttle Position (TP) sensor, Mass Airflow (MAF) sensor, Heated Oxygen Sensor (HO2S), Engine Coolant Temperature (ECT) sensor, Octane Adjust (OCT ADJ), barometric pressure sensor, Vehicle Speed Sensor (VSS), and Brake On-Off (BOO) switch according to a spark advance map programmed into the PCM. The PCM produces a Spark Output (SPOUT) signal which it sends back to the ICM. Using the SPOUT and CKP information, the ICM switches primary current to the ignition coils among the three ignition coils and provides the optimum amount of spark advance and dwell. The ICM module also sends back to the PCM an Ignition Diagnostic Monitor (IDM) signal which the PCM uses to indicate a failure mode and which is also used to provide an RPM signal to the instrument panel tachometer.

Does this model have a fuel pump driver module or is it built in to the ECM?

The cam sensor will bot cause it to dies out like that. Even if it fails while the engine is running, it will stay running until you shut it off.

Then it will not restart.

No, it does not have a driver module at all. The ECM is a switch to turn it on and off.

1995 was way too early for that kind of electronics.
