#110 of 131 2000 Chevy Venture Heat and Idle Issues by tjh87

Jul 05, 2011 (10:29 pm)

Back around January I was driving our Venture (right after a snow storm, clear and cold) and it said the coolant was hot, gauge was as far as it cold go to the right. Nothing noticeable that shown any overheating, nor did any noise go off, although I don't know if this happens when the car overheats. A few months back after the car drove about 30-40 miles, and was turned off for a few, it would start then stop, and it sounded like it was idling low and misfiring. Tried a few times, gave it a rest, and about 15 minutes later, it ran fine. Nothing happened for the rest of the night about another 40-50 miles. My father said it happened a few weeks later.
 
Recently the heat gauge has been going from about half way between the middle and Hot to the middle and Cold (middle being the vertical line in the center for clarification) in a matter of second, and seemed a bit unreliable. Now on Saturday it reached H with the hot coolant in the display and no noise about 4-5 times, usually while it was stopped (same drive as the one before when it start and stall), started up fine after we reached our destination (car said hot coolant both on the gauge and the display, car was off for about 5 minutes), and was fine the rest of the day, about another 80 miles. Now again today, driving home, it reached H and all, and after I got home, I tried starting it, and it would start and stop. 15 minutes later and some gas, ran fine except for a little vibrating which happens all the time. When it started and stopped, it sounded like it was trying to hold idle, then it would drop, reach idle again, drop in idle, and then it would either stall, or reach idle, drop idle, then stall. We believe it could be the computer, but no real clue. Another idea would be the engine protection that kicks in when the engine overheats, but that doesn't happen while driving (car felt like it always does). Any ideas?
 
Also, when the car overheats, does it make a sound or an alarm (I hear none although the display says engine coolant hot and gauge says the same)? Or is the display and the gauge tied together, and the display is not triggered by the comp but the gauge?

OK. We finaly solved the problem for my Chevy Venture engine racing. We removed the throttle body to make sure that the gasket was not leaking and to make sure the idle sensor was sitting right. What we discovered was that the TPS (Throttle Postioning Sensor) needed to be replaced. We replaced the gasket and TPS and the car runs fine.
Thanks to all of you for your input.

#112 of 131 Venture starts intermittently by wdf73

I have a 2002 Venture. A month or so ago, it died while my wife was using it. After a lot of messing around, I discovered the plug that goes through the floor behind the driver's seat was bad. I replaced it, and all went well for a while. Then it died again, (Thankfully in the yard this time). Both times the fuel pump was not kicking on. I went through all the connectors, tried hot wiring the fuel pump, and finally dropped the tank. When I unplugged the wiring connector from the pump, I noticed some corrosion, so I cleaned it up and everything seemed to work. Now I have had fail to start twice. Both times it runs well until it is shut off (both times on a hot day), then will not start. One time a friend was helping me and removed the tubing from the fuel pressure regulator and the pump started working, and the next time I disconnected the plug from the bottom of the van and hot wired the pump to test it. It started up and then worked fine when I hooked the plug back up.
If I understand the wiring diagram right, it appears that if the fuel pump relay closes, it provides power directly to the pump. Do I have a pump that is going bad and has a 'dead spot' in it, or could the relay be going bad?
Thanks for the help!

So sorry for the late late reply. Had to change the water pump anyway so I took apart other stuff to get to the camshaft position sensor. But for the life of me, just couldn't easily remove the power steering pump without disconnecting hoses.. Did not want to disconnect the p.s. hoses for a relatively minor problem. No codes are ever set. It just takes a second start sometimes if the engine has been off between 10 - 60 minutes. Strange that before and after that range it starts fine. Thankfully the starter is relatively new so it can take a beating and still keep cranking!

#115 of 131 Engine runs for a minute or too then stalls by benson75

Nov 14, 2011 (3:51 pm)

I have a 2003 Chevy Venture. Recently it started stalling on me. I changed the fuel filter, and air filter. I got codes that led me to change the coil packs and module. When I went to start it up gas shot out of the fuel pressure regulator. I replaced it. Now I have no codes, and when it starts it will Idle for a minute or 2 and then stall. If I try to give it gas it begins to shake and stutter. I have no Idea what it could be since there are no codes. As far as I can tell I am not getting any vacuum leaks anywhere. All of the wiring seems good and connectors are good, and tight. I also replaced the plugs and wires. It is still having the same problems. Does anyone have any ideas of what the problem could be? Any advice would be extremely helpful. Thanks.

I have just started having the same problem with my 2000 venture it also happens when i will be driving and the start to stutter some times it stalls I just had my fuel pump replaced and as soon as I left the mechanics it did it again. Did you have any luck finding out what it could be?

I had this exact problem on my 1997 Chevy Venture. Stalling, no codes, no other apparent problems. I solved the problem by replacing the Camshaft Position Sensor. The sensor is located on the passenger side of the engine near the top. You have to remove a lot of stuff to get to this simple sensor, but it worked. Now I have no more stalling, failing to start or other related anomalies.
 
I also changed the Crankshaft Position Sensor just because . . .

Thought I would share this. A few days ago, our Venture after pulling it into the garage and shutting it off for 5 min it would not start up. Acting like an ignition problem, I ran tests and replaced a few parts. The Ignition switch and relay and checked all related fuses. Having my wife try to start the van while I checked the circuits and tapped the starter I noticed the starter start smoking at the purple ignition wire on the starter solenoid. Around a month ago the Venture had a oil leak from a sensor right above the starter. I replaced the sensor and it ran great. The oil is now causing the starting problems. I plan to replace the starter and clean all leads. It should take care of it. Hope this helps. I was on the right track with the ignition curcuit.

I am currently having the same exact issue with my 2003 Venture...Did you ever come up with a solution for your problem? I really need help figuring this out cause the shop that my van is at wants a $1000 to replace the computer in the van but they are not sure that is what is causing the problem...I am NOT willing to give that kind of money without a positive answer for problem to be fixed.
