Sorry for the non Nova question but this is the only place I can get a straight answer. Some times on startup the truck will lurch forward slightly. It has been doing this for a while but lately its been getting worse. Its like the starter is having trouble starting it in gear. 350/ 4l60e

Any ideas would be much appreciated

sounds as though the converter isn't unlocking, call a GM dealership

thanks do you think this is something computer related?

I'm not sure I understand what's happening. When you start the truck in park, it lurches forward? If that's the case, then the shift linkage and/or the neutral safety switch isn't adjusted properly.
If it starts fine in Neutral but not in park it may be the lockup is not releasing.
If so, there may be a TSB outlining the problem and how to fix.

On a side note, I also own a '96 Chevy pickup. One problem you will run into sooner or later is insufficient fuel pressure causing a hard to start/no start condition. The shop manual says the Central EFI system requires a minimum of 57 psi to open the poppets. It really needs 62 psi to start properly especially when cold. Factory Delco (delphi) pumps eventually lose pressure even though they still work. This fools anyone trying to diagnose the problem because the pump is running and there is fuel pressure in the rail, so they assume it's "not the pump". Put a pressure gauge on it. If it's not at least 58-60, replace the pump.
Some brand new generic pumps from the parts store may not have the pressure needed. I went with the Bosch pump and it has 62 psi.

I have the same problem with my 2000 GMC Sierra with 5.3/auto. Mine only does it when it is cold though. Took it to the dealer a few years ago and they just told me to live with it because they know I wouldn't want to pay for the diagnostic charges. They did not find any service bulletins either. Just one of the many, many complains I have about this truck...should have kept my K5 Blazer. If it makes you feel any better, the condition has not gotten any worse since I noticed it a few years ago. Should be nice enough soon so that I can drive the Nova daily and forget about the truck for a few months.

Thanks guys, I will try to start it in neutral instead of park and see if anything changes. Also this truck is on its 4th fuel pump, 2nd transmission, and 2nd engine 120,00 miles. I didn't own the truck then but the trans and torque converter were fried at 30,000. Somebody slap me because I am temped to go buy a Honda so I don't have to worry about it.
Also Paul, has the factory paint peeled of your truck yet?

(No offense to Honda owners I'm just jealous of your peace of mind and good gas milage)

If the transmission is bad, you can get a GM replacement with a 3yr 100k warranty. And it is built specific to your trucks application. Not a generic rebuild!

Also that is low miles for your problems. Lot of people (A LOT) have well over 200k registered on these trucks with original engine and trans.


A common problem on many General Motors transmissions is the Torque Converter Clutch fails to release and causes the car to stall when it comes to a stop. Most of the time it is a stuck Torque Converter Clutch (TCC) solenoid, this is the most common problem, not the converter, the TTC Solenoid itself, a part that is rarly changed in aftermarket rebuilds. General Motors has issued a few Technical Service Bulletins (TSBs) relating to this problem. There is also a specific diagnostic procedure to determine the exact cause of the TCC problem. I have no idea what that procedure is.

Good luck,

Al

My last three Hondas were frequent guests of tow trucks. Blown engines, failed transmissions and bad ignitions. Dealer service is pitiful. My 2000 Accord got to 3500 miles before it needed a rebuilt tansmission. the replacement transmission and suspension system were so dangerous, I wouldn't let my daughter drive it. The 2002 RSX made it to 20K miles on before the engine blew. The transmission was going when when we sold it. My 98 Civic actually went 3 years for it developed ignition problems that required three trips on the tow truck. We sold it too.

I told the Honda dealer all wanted was for my new Accord to work as well as my 10 year old Dodge minivan and I was being serious.

I hate to sound sarcastic but so what if it lurches foreward. Its in park right? where is it gonna go? Ever tried using the parking brake and see if the problem goes away?
