Engine stalls out while driving?

I have a 2001 chevy venture. Today I noticed a puddle under my van that wasn't there yesterday. Then as I was driving today and turned into a parking stall there was some grinding. A couple hours when I left, there was a puddle where the car was. Just a couple weeks ago we were in an accident resulting in wheel barings and axels needing to be replaced.

Driving van on high way got off on an exit started to stall punched gas to make it in to parking lot van died tried restart sounded like it was out of gas replaced fuel pump old one sounded intermitin and fuel presseure not high enough motor starts runs like crap for a few secounds then dies then sounds like its cranking againts compression struggling get a back fire though intake once in a while then it will fire and stop the motor from cranking tried a new cam sensor still same allso getting a strong smell of gas in oil thought about changing crank sensor but still get the hard cranking I think this motor has the nylon timing gear but not for sure could it have jumped timeing please help any ideas will be used Oh and allso new plugs and wires and o2 sensores less then 1000 miles ago and water pump and fuel fillter and fuel pressure regulator ****help*** junk yard is next for it

OPEN REAR SLIDING DOOR RIGHT AT
THE DOOR REMOVE PLASTIC STEP PLATE PULL UP CARPET YOU WILL SEE THE REAR WIRING HARNESS THE
PLUG MAY BE CORRODED OR SEVERED TRY THIS IT MIGHT HELP YOU WITH YOUR PROBLEM.

GOOD LUCK,

My venture Stalls when I let off of the gas only when outside air temp is below 38 degrees (or around there). I took it to a garage and they had the code for MAF sensor. I chnaged the MAF and it still stalled. Took back to garage and same code MAF sensor. I changed it 2 more times and still stalls. I also changed the IAC valve and the van still stalls. When the air temp is above 38 degrees it runs like a top, it runs smooth no miss no stall. I also checked and replaced the Air intake tempeture sensor and it still stalls. I am lost and loosing my mind, can someone please help me?

Thank You for the quick response. I checked the temp sensor and I had a reading of 3.42 ohms when engine is cold and 0.56 ohms when engine is warm.

I took the wrong reading on the ohms meter. I will check it again when the engine cools down and get back to you. It was about 122 degrees when I went back out to check it which would be slightly warm.

Racefan966, I really couldn't test the temp sensor on the van that well so I took it out. I get different readings saying it's 95 degrees to 112 degrees. The sensor is cold. The readings won't stay on, they flash for a second then I have to make contact again to get another reading. Does this mean the sensor is bad? Or am I doing something wrong. Hope to hear from you soon. Thanks again

The OHMS reading was around 1800 when it was cold. It was only 12 bucks so I replaced it. Any other suggestions. Seeing that it is temp. Related and with everything I've replaced, do you think it might be the EGR valve? Also I forgot to mention before, the garage where I took the van to said they checked the wiring for the MAF sensor and they said they checked out ok.

Yes the service engine soon light came on today. I have a friend at work who is bringing in a code reader and I will post the codes tomorrow. Thank You again for your help.

Racefan966 Thanks again for your help. Here is the code the scanner gave me: P0101 MAF or VAF A CKT Range/Perf 1 of 2 codes 2nd code pending. I also have a question. If the code was never cleared after replacing the MAF and the other sensors I replaced, would this cause the computer to try and make adjustments to the engine if it is reading this code. Thanks again hope to hear from you soon.

Racefan966, I unplugged the MAF sensor and the engine idled fine for about 2 min. Then it started idling erratically ( slightly up and down). Other than that it seemed to idle fine.
