SOURCE: 99 gmc safari van,wont start,no fuel pressure to the filter

Do you hear pump cycle (hum) when you turn key to on position?
Take air intake hose of front of throttle body & spray WD-40 inside throttle body with plate open for a couple of seconds, then see if it will start & run for a second or 2. If it fires up for a short time, it is fuel related problem. Perhaps autoparts store lends or rents fuel pressure gauges, which will confirm if pump is working or not.

SOURCE: 97 safari won't start when wet

Had same exact problem, it was a bad coil. I could not duplicate "no start" problem with water bottle. Replaced coil and problem gone.
Note: There was a noticeable engine misfire at highway speeds on humid days. This accompanied the no start problem.

SOURCE: My 1997 GMC Safari Van will not start when cold

Check for a bad temperature sensor. To check it, remove it first. Using an ohmmeter measure its resistance, which should decrease when dipped in hot water. If the the resistance remain high and doesnt change then you know it is bad, and you don't end up wasting money on buying one when it is still good.

I have a 99 safari sle i have a problem, i will be running fine then i all of the sudden get a sputter and stall wont start for 15 min

If it only does that while under demand, that is going up a hill or accelerating, fuel filter or pump intake is getting plugged. If it is happening on hotter days or when in the sun, a relay is heating up, separating bad solder connections. Many other possibilities include weak spark coils, contaminated fuel, dirty sensor connections. Is your Check Engine Light on? Go to a parts store and borrow their code reader. Some Auto Zones and others allow this.

99' GMC van "sputters" or stalls around 2k RPM

Usually the failure of the regulator results in a fuel leak either externally where it would be seen or internally where the engine wouldn't run. If the filter hasn't been changed in a while it should be changed. Also, the spark might be bouncing around the wires or cap. I've even seen it bounce out of the coil. That would sound like a clicking noise.

The fuel pressure regulator on that Vortec engine is under the upper intake plenum, on the back side of the central fuel injector. It is held on with a slide clip.

I have a 1999 GMC Safari. Van will drive fine for

see when you say you step on it, and the vehicle stalls, it sounds as if it bein starved of fuel...you step on it, and therefore the demand is there, but not the supply. to prevent itself from over heating, the fuel pump shuts off...after a moment of cooling off, it fires right back up...get it checked at your mechanic...do the strainer on the bottom of the pump, and fuel filter as well...is it time for a tune up yet?
