Stops and may or may not start right away. Turns over, no fuel. Sometimes brief interruption at highway speeds but continues to run
Water in Fuel and Service Throttle Soon lights come on. Changed fuel filter on back of block. Seemed better at first. Now is worse.
Changed alternator just before this started.

That
red wire is only for the fuel heater.will not cause a no start.try pumping
the primer pump on top of the fuel flter hsg. but first open the bleed
screw,which is black plastic also located on the top.this will eliminate any
trapped air that might have entered the fuel intake system.if the pump does
not get firmer and harder to push, then you have a leak in the fuel supply
lines or the ck valves in the fuel filter hsg or stuck open. Still no start
have it scanned to ck fuel pressure while cranking.it should be close to 5000

Similar to above. Loosen the screw holding the dash panel and insert a paper clip or screwdriver to lift needle over rest bar.

It does seem to be a fuel problem, If your engine is fuel injected the fuel pump is in the gas tank. As far as the ground it is grounded through its harness and mounting.. First thing I would do is put a fuel gauge on the fuel rail fitting and check fuel pressures. Pump wil run for a few seconds when the key is turn ON., and then stop ( assuming its working ) A lack of pressure willindicate an inop pump, or even possibly a clog in the fuel filter. Let me know.

By looking at the schematics, I would have to point towards the module if both seats have at the same time. If you can't see the wiring diagrams, email me at [email protected]
