I think you should check the fuel pressure. If you can hear fuel gurgling, the pump is probably trying to prime, but may not have adequate pressure.
First, try to go to a repair facility and get an OBD code reading to see if any error codes come up.
If not, performa a manual pressure test with a fuel pressure test gauge. Most Advance or chain auto stores have ones you can borrow with a deposit. There is a test port that I beleive is on the fuel rail. Also, double check th econnection of the fuel pulsator. This should be located where the fuel injector lines culminate.
Also, the oil pressure switch acts as a back up circuit and will cause problems. It can be tested by disconnecting the fuel pump relay and trying to start the van. If it starts it is okay, if not it needs replacement.
To test the fuel pump relay, do the opposite and connect the oil pressure switch and disconnect the pump realy. The engine will not even get that gurgling sound as it will not even try to prime the system. It can still be failing and not be providing 12 volts to the pump. To test his there is a red wire coming out of the pump relay. Apply battery voltage with jump wires. The hot wire or positive is the gren and white wire coming out of the relay and the ground is black and white. Check for continuity with an ohmeter. If the resitance is infinate, not continutiy, the pump realy is bad.
The fuel pump test connector is next to the fuel pump relay on the drivers side of the firewall.
The fuel pressure with the key in the on position should be, 60-66psi.
There is an in-line fuel filter. I am trying to find the location. That could be clogged.
See how this goes and get back to me.
