Went through 4 fuel pumps now!
 
This last weekend replaced the fourth one, fuel filter, and flushing the tank thinking that would fix any issues I was having with the no start. Wrong! Still no fuel.
 
On a whim I replaced the fuel relay and cleaned the contacts in the fuse block that it plugs into. Started right off. The old relay tested good but when plugged back in, it failed to let the pump run.
 
So don't forget to clean all your electrical connections while diagnosing your fuel problem. I went so far as to clean and put electric greese on all the plugs under the van that went to the fuel system too.
 
I'm crossing my fingers that that will solve all my fuel problems.

IT WAS NEVER MY FUEL PUMP LIKE WE THOUGHT IT WAS. DONT KNOW REALLY WHAT IT WAS. ONE DAY MY 15 YR OLD SON WENT OUT THERE AND CHECK UNDERNEATH AND FOUND A WIRE NOT CONNECTED PLUGGED IT IN AND CHECK ALL THE FLUIDS, TOUCHED THE GAS THROTTLE AND A PLUG THING WHERE THE FUSE BOX IS IN THE ENGINE AND AMAZINGLY THE STUPID THING STARTED RIGHT UP. HAVENT HAD A PROBLEM SINCE. THIS IS WHAT I THINK, EVERYTIME I FILL MY TANK FULL AT QUIK TRIP I HAVE HAD PROBLEMS WIT MY CARS. THIS IS THE 3RD CAR THIS HAS HAPPENED TO. SO I DONT FILL UP AT QUIK TRIP ANYMORE. I SAT HERE FOR 2 WEEKS WITHOUT MY VAN AND ALL IT TOOK WAS A 15 YR OLD TO GET IT RUNNING AGAIN. FUNNY HUH? WELL GOOD LUCK ON YOURS..

After all the work done a couple of week ago.
 
Well my van died again the other day going down the road. Same simptoms as before: crack but no start, just not getting any fuel.
Had it towed home and started metering from the ignition to the fuel relay then to the wire harness under the van going to the fuel pump. I was tracing the flow of power.
When I got under the van and pulled the harness to get some slack and expose the wires to meter I asked the wife to turn on the ignition to give me power. Low and behold the fuel pump kicked on. The only things that moved under the van was the harness going to the fuel pump and the main harness plug going into the van just behind the drivers seat.
When I unplugged the water tight plug one of the terminals was scorched black(its a white plastic 8 pin plug). That terminal is the 12v going to the fuel pump. My guess is it is arching and looses contact.
Makes me sick to think that I have paid for 4 fuel pumps to be replaced and it might have been this all along. Just so happens that when you drop the tank that wire gets moved around and corrects the contact fooling you into thinking that the fuel pump was the problem.

My 98 Venture by djmike

I am new here. I am having a problem with my 98 Venture. The thing won't start. If I ether up the throttle boddy it will start until it burns the ether out but fuel is not getting into the engine. I have had the fuel pump replaced, and the switch checked. I have not yet had the fuel filter replaced. I'm at my wit's end because I took this thing down to Chevy and they didn't even hook it up to their machine. told me it was the camshaft and didn't even hook it up. One garage I went to told me it was the fuel pump and it was not. Then the Chevy dealer wasted my time and I should have charged him for wasting my time. I don't think it's the camshaft, I'm ticked and am going to take it to the Pontiac dealer to see if he would help me.
  When I got the Venture it needed fuel filter and it broke almost caught the van on fire and almost blew up. Gas was everywhere. So from reading these posts, it says to check the wiring harnesses? I'm going to replace the fuel filter besides it was due. If anyone has any suggestions for me before I take my auto motives down to the Chamber of Commerce to discuss mechanic quackery. Please let me know. I just want to get my van fixed.

The gas guage on my '01 Venture is not working right. Fll then straight to empty at +/- 350 miles. Understand it's the fuel level sending unit on the fuel pump. How do I drop the tank to get to it? Something I can do in the driveway?

yes...it is pretty easy...it is a plastic tank, so it is light. empty gas as much as possible and then depressurize the lines (simply remove the fuel pump relay from the fuse box while the engine is running, and that will do it!), turn off engine, disconnect negative battery terminal, disconnect the two fuel lines and the electrical connections and remove 3 bolts that hold the three straps up. then unscrew the huge lid on the tank, but be careful as you then have to tip the unit as you take it out, since the sending unit goes horizontal in the tank. Just do it slow, and you'll realize what I mean. Hope this helps...

I am havinghte exact same problem! I climb under the van and wiggle the plugs and the van fires right up, but then dies in the middle of driving, have replaced the plug but now think I need to replace the actual module that it plugs into behind the drivers seat. Need to find the part but don't know what it's called? any idea?

Hi,
Which exact problem are you having? These threads don't seem to run correctly. Anyway, I ran 12v directly to my 2000 Chevy Venture fuel pump, bypassing the "module" that is to supply that 12 volts. I think it is called the ECM (electronic control module) or something like that. I would like to replace mine as well, so I can get rid of that direct 12v (fused, and only on when ignition is on) wire! By saying it is behind the drivers seat, you mean INSIDE the care, on under the car and behind the seat, right? Just curious.... I have no idea where that module is...
Jim
