Right after I made a left hand turn, the engine stalled. I coasted for a second and stopped. Fuel was low but not empty. I tried to start the engine, but it would not start as if out of gas. The van sat for about than forty minutes while I got fuel. Put a gallon in, the engine started, but stalled in about ten seconds. I tried the engine again and it would not start. I let it sit for about fifteen minutes. The engine started but stalled in 7 seconds. ? I am stumped. Lol

I have checked the coolant level, I have cleaned electrical fuel connections. I will be using an OBDII next. Any suggestions before I do this. What might be a quick and inexpensive fix for this problem. I am at my wits end because the tester may not read it.

Thank you for any help and have a great day.

Check fuel pump fuse !

Also check? SECURITY Indicator Illuminated and Engine Does Not Start
The theft deterrent control module (VTD) or the PCM has detected a problem with the theft deterrent system. The VTD module is unable to measure the ignition key transponder value. The System is in Learn Mode, refer to Programming Theft Deterrent System Components

Was driving and the engine shut off. Now only four of the rocker arms move when I turn it over. Could it be the oil pump?

If only forward rockers are moving, then you may have broken a camshaft. The root cause could still be a bad oil pump. With that many miles, anything is possible. You need to look into it further.

I replaced a bad intake manifold gasket. The van started but ran a little rough. I changed out the original plugs and it ran great even took it for quick ride, no issues. The next morning I started it and went to back it out of the garage when it suddenly stalled and would no longer start.

I am getting no reading from the cam sensor and was told that its failure should not prevent the van from starting. During removal of the power steering pump I may have inadvertently crushed the sensor when trying the pry the pump off.

Given that the van was running at one point could the bad sensor be the cause of its failure to start?

There are some variations between models and engines over which sensor(s) can stall the engine, but in general, crankshaft position sensors and camshaft position sensors tell the engine computer when to fire an injector or ignition coil. With a missing signal, there will be no spark and/or no injector pulses. Usually the fuel pump will also be turned off.

These senors often do not set a diagnostic fault code in the little time they have as a stalled engine coasts to a stop. When you do get a fault code, it only indicates the circuit that needs further diagnosis. They never say to replace a part or that one is bad. In this case you have the luxury of knowing physical damage is the likely suspect. I'd look for a crushed connector plug first. If the sensor is actually cracked, it could have still worked for a while until an internal wire or connection broke. Also, some GM engines will not start with a failed sensor, but if that failure occurs while the engine is already running, it will continue to run until it is stopped, but then it will not restart.

I changed out the cam sensor and ran a continuity test on the wires. The wires checked out, so then I replaced the ignition control module but still have no spark. Not sure if I should replace the coils next.

Thoughts?

BTW it's a 3.4, I see that I've listed it as 3.1, sorry

We rarely approve of throwing random parts at a problem. If you have a coil pack with three ignition coils, you know all three didn't fail at the same time. Also, that would cause a crank / no-start due to loss of spark only. You'd smell the unburned gas at the tail pipe. If you don't smell that, you aren't getting injector pulses or spark. That would point to the cam and crank sensors. If there is no fault code related to either of their circuits, you'll need a scanner to see if their signals are showing up at the Engine Computer.

As I mentioned earlier I did replace the cam sensor and checked the wiring. Replacing the crank sensor did the trick. Thanks so much for all your help I couldn't have done it without you.

BTW Do you know anything about '84 Chevettes?

When I start my engine it races maybe at 1500 rpm and if I try hit the accelerator peddle it races at a even higher rpm. I talk to someone at the parts store I asked them if I should replace the throttle position sensor. They said I should replace the throttle idler solenoid and I did it really did not improve. I notice that after engine runs for1 or 2 minutes if I shut off engine and restart it runs at normal idle speed. What can be done?

Symptom Definition
Engine runs unevenly at idle. If bad enough, vehicle will shake. Idle RPM may vary. Engine idles at incorrect RPM.
Check the following items:
Check TP sensor for sticking and binding. Check for correct TP sensor voltage. See FUEL SYSTEMS in appropriate SERVICE & ADJUSTMENT SPECIFICATIONS article.
Check to see if condition is caused by engine running either rich or lean.
Check Park Neutral Position (PNP) switch circuit. Ensure PNP switch is properly adjusted.
Check for poor quality or alcohol contaminated fuel.
Check in-line fuel filter. Replace if dirty or clogged.
Check intake and exhaust manifold passages for casting flash.
Check fuel system for incorrect fuel pressure. See BASIC FUEL SYSTEM CHECKS in appropriate BASIC DIAGNOSTIC PROCEDURES article.
Check fuel injectors. Perform injector balance test. See FUEL INJECTOR BALANCE TEST under FUEL SYSTEMS in appropriate SYSTEM & COMPONENT TESTING article.
Check exhaust system for restrictions, such as a damaged or collapsed pipe, muffler or catalytic converter. See EXHAUST SYSTEM BACKPRESSURE under MECHANICAL INSPECTION in appropriate BASIC DIAGNOSTIC PROCEDURES article.
Check for fuel in pressure regulator vacuum hose. If fuel is present, replace regulator.
Check injector harness locations. Ensure injectors are connected to correct injector/cylinder according to firing order.
If rough idle occurs only when engine is hot, check PCV valve for proper operation. Check evaporative emission control system.
Check PCV system for proper operation.
Check engine compression. Check for incorrect valve timing, bent push rods, broken valve springs or worn camshaft lobes.
Remove spark plugs and check for wet plugs, cracks, improper gap, burned electrodes or heavy carbon deposits. Also, check condition of spark plug wires. Spray spark plug wires with a fine mist of water to check for shorts.
Ensure initial ignition timing is properly set.
Check Knock Sensor (KS) system for excessive retard.
Check engine idle speed (both base and PCM idle).
Check Idle Air Control (IAC) system. Check for foreign material in IAC bore.
Check EGR system for proper operation.
Check Power Steering Pressure (PSP) switch circuit.

We had an '84 "Vette" donated to my Automotive program. I'm an expert on the charging system because I built a lot of bugs into it for my students to find.

First have this checked with a manual oil pressure gauge. Then replace the oil filter iwth a new or good one as well as an oil. If this is a 3800 you shouldh avhave packed thpump with a little vaseline so it would prime. You culd also have bearing wear causing this.

Enter your question.2001 Chevy Venture Van, am Driving and engine just stops. Wait a while and restarts? Changed fuel filter, but still just stops running. This last time tried to restart but battery went dead, now charging. Seemed to starve for gas, but not sure. If problem is fuel pump wouldn't it not run anymore at all. So running some for a while would eliminat pump right? Short in computer wire? Etc, I just don't know> Help, puzzled colt

Do below and get back with some testing results:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing
belt/chain.

Fuel pump is working, it seems to loose spark off then on then off again, car seems to have some electrical problems in the dash, such as gas gage reading a false reading,
I was told to replace module, what should I do?

Try resetting your security system first then if still thee scan for codes and check fuel pressure with a gauge auto parts rent it.
