As im driving the van shuts off. When I go to turn it on I have to have the gas peddle pressed and the van in neutral. It will start jumping and make a pumping noise. It usually takes 5-10 minutes for it to go away and will eventually come back.

Hi
My 1999 Venture van has been off the road for 11/2 years. Now I am trying to get it back on the road, it was running fine before being layed-up
It starts OK and runs for approx 5 minutes then starts to splutterand stop/or just quits and will not start again until it has cooled approx 5min
Regards
Mike

Is there engine light?
When last time you did tune up?
Have you ever changed the fuel filter< since it got 22000 miles/?

Thanks for your response
Check engine light is only on sometimes.
Used diagnostic tool shows codes PO117 coolant input low and P0118 coolant input high.
Fuel filter/air filter and front spark plugs changed, vehicle still runs the same stopping after it warms up and is then hard to start and runs rough.
Oil changed and was not milky, no water dripping from exhaust. Exhaust only a little white.
Trying to change the rear plugs, rotated engine forward but finding it very difficult to get to rear bolts of coil pack mounting bracket, passenger side one has plastic plug on top of it.
Regards
Mike

The performance problem is related to the codes.
The coolant sensor may be faulty.
Short to ground circuit between ECT terminal A and PCM connector terminal 4p
ECT signal and ground circuit circuit short each other.
Here is what you need to do.
- Inspect if ECT sensor terminal is bent.
Turn the key to off
Disconnect ECT sensor connector
Check for bent ECT sensor terminals A and B
- Determine is ECT sensor malfunction or hasness malfunction.
Mesure resistance between ECT sensor terminal A and B
the resistance should be within 2.27-2.74 kilohms(20*c 68*F
- inspect ECT siagnal circuit for short to ground.

Turn ignitiion key off
Disconnect pcm connector
check continuity between ECT sensor terminal A and body GND
check continuity between A and B harness side.

Report what you have find.

ECT sensor terminals not bent
Resistance between terminals A and B 50 kilohms at 5*C
Continuity between sensor terminal A and body 800hms
Continuity between A and B harness side 1400hms
(did not disconnect pcm connector)?

Replace the coolant sensor.
Clear the code
start the engine.
Is the DTC present?

Recently changed crank sensor on van because it would not start just kept on rolling. Was so happy once I installed it because car started up each time afterward. Later on that day, while driving van just died as I was slowing down. Pulled on the side of the road and restarted van which it did but it kept dieing about a second later. I have been told that some air flow might be the cause. Any suggestions?

Coolant sensor replaced P0177/0118 codes cleared.
Engine now misfiring dtc code
P1374 crankshaft position sensor 3X reference circuit.
I have Haynes repair manual and it only refers to 7X and 24X. Why does the code only refer to 3X?
Tasks completed
Change fuel filter, coolant sensor, PCV valve, spark plugs and wires, air filter.
Thanks for your continued support.

Try resetting security system and cleaning throttle plate on both sides with choke cleaner and iac hole. Then scan for codes and check fuelpressure with a gauge autoparts rent it.

The 3X reference signal is produced by the ignition control module. The ICM calculates the 3X reference signal by dividing the crankshaft position (CKP) sensor 18X pulses by 3 when the engine is running and when CKP sync pulses are also being received. The PCM uses the 3X reference signal in order to calculate engine RPM and the crankshaft position at engine speeds above 1200RPM. The PCM also uses the pulses on this circuit in order to initiate the injector pulses. The PCM constantly monitors the number of pulses on the 3X reference circuit, and compares the number of 3X reference pulses to the number of 18X reference pulses and CAM signal pulses being received. If the PCM receives an incorrect number of pulses on the 3X reference circuit, the PCM will use the 18X reference signal circuit for fuel and ignition control. The engine will continue to start and run using the 18X reference and camshaft position PCM input signals only. DTC P1374 will set.

Conditions for Setting the DTC
The ratio of 18X reference pulses to CAM signal pulses received by the PCM equals 36:1.

The ratio of 18X reference pulses to 3X reference pulses received by the PCM does not equal 6:1.

Test for the following conditions:

A malfunctioning ignition coil--Remove the ignition coils and inspect the ignition control module and the coils for cracks, carbon tracking, or for other signs that indicate that the coil secondary circuit is arcing to the ICM or to the ICM wiring harness. Refer to Ignition Coil(s) Replacement and ask you needed.

The secondary ignition wires arcing to wiring harness--Inspect the secondary ignition wires for carbon tracking or for other signs of damage.

Iac hole? WHat is that?

Also is there any chance that by installing crank sensor while battery terminals were connected might have something to do with it or the fact that the car started and ran shoud rule that out?

Removed coil pack and coils from ICM,
No cracks or visual signs of arcing or carbon on coils or ICM only signs of oxidization (white powder)
Not sure what you mean secondary wires, if you mean the electrical plugs that connect to the module they are fine no signs of arcing.
While checking wires noticed the plastic air tube that connects from the air intake duct (next to the intake air temperature sensor) to the back of the engine block was pulled out of the block and is a very loose fit when pushed back in, please comment
Thanks

Iac hole is an oblong hole in throttle body so the idle air control motor can let it idle all you are doing is cleaning the carbon out. Battery on with crank sensor doesn 't mean anything. Once again scan for codes and check fuel pressure with a gauge like I said in last reply. Anything other than that you are trying to guess what is wrong with it. Should have 60-66 psi fuel pressure

Add info to last reply
Resistance across each set of terminals of the coils is between 5000-6000 hms and btween each set of terminals on ICM 4500, 8000 and 5000 hms

Hi was able to get a scanner on the vehicle and its returning P0107. It seems as if thts the MAP sensor. Do u recommend I replace immediately or should I check something else or run test?

2 likely causes are
the ignition control module, or the computer(pcm). But there could also be a wiring problem
between the two. Sometimes the wiring harnesses of the ignition control module
rub on the module, coils, or plug wires and give false signals
The plastic air tube that connects from the air intake duct (next to the intake air temperature sensor) to the back of the engine block is part of cranckcase ventilation.

Replace it because a lot of cars won't start with that bein bad. Of course it cold be bad wiring or connection or even a vacuum leak around sensor but you have to start someplace.

Electrical problem
1999 Chevy Venture 6 cyl Front Wheel Drive Automatic

I have a 1999 Chevy Venture. I have had the alternater replaced and the battery, within the last week, but I am still lossing power then my engine is shutting off. I could be going down the road when this happens, or just sitting in my driveway.

This is exactly what happens:

The radio and dash lights go off, I step on the gas and it will only go 10 MPH with it eventually catching up (after about 2-3 mins). Then once it gets to the proper speed, the engine shuts off and I can't restart it for over 2 hours.

I've checked all the wires, nothing is loose. Any ideas?
