Hey all GM enthusiasts!
Have a problem: Starter engages and cranks (not starter), fuel pump runs (not any pump or fuel relay), Aleternator and battery tested OK. So what is it? Again, the starter cranks and will continue to turn over very powerfully until the battery drains! Started off slowly, couple seconds to turn over, then a little longer, and a little longer, and now it won't (or it's intermittent). Have no idea and need my 99 TA back ASAP! Please, any input will be appreciated!

Do you have:
Fuel pressure to injector rail?
Spark?
Signal to injectors?

did you change to an aftermarket pump? if so, a line could be crimped or something. are you getting spark? pull a plug and see. look at night nad see if theres any arcing on the wires.

I understand you're concerned, but four copies of the same thread really isn't necessary Makes it harder for people to help when they aren't seeing the ideas everyone else posted, too.

Choose one forum and we'll consolidate this there...

Edit, 5-15-05: okay, since it's been more than a week now with no sign of this guy (and he last logged on a day after I made this post, so he certainly could've seen it), I'm just going to merge them with the one in External Engine since it has the most replies.

have you tried ignition relay switch

May be a clogged fuel filter if it's not the ignition. Or maybe the pump isn't getting fuel from the tank?

Check your ignition relay. It is next to the starter relay. Swap them and see if it makes a difference. I am assuming that you checked the fuel injector fuse.

I think juju is on the right track... I'm still learning about the LS1 style motor because it is going to be big part of my future.... but until then I defer to the experts. I would suggest sending a personal to "Nogo", he knows just about everything when it comes to the LS1... by the way his name is Kevin and he drives a pro-charged WS6.

I just diagnosed the same problem on my neighbor's SS. It was the ignition relay.

Sounds similar to what mine is doing right now. I can turn the key on and off several times (letting the fuel pump run until it kicks off each time) and then it will start, so I assume mine is the pump. Try it maybe that is what yours is also.

My 02 Ram Air Did That To Me Once What I Did Was Reset My Computer By Unhooking The Battery Plugged That Back In. Then I Locked The Car With The Remote Then Unlocked And It Started Sounds Weird But It Worked...?????

I had the same problem after I pulled my engine and did a heads and cam swap. Two days later after trying everything we found the crank sensor wires melted together. We repaird the wires and it started right up.

Thanks to everyone who gave me advice- but just to let everyone know.... it was the relay after all. I went down and got the ignition switch.. relaized I had to pull the sterring wheel... isnce it was about 10:00 at night and I had no puller, I decided to dink around anyway- so I switched some relays around and boom! started right up. Thanks to everyone who posted.. i really appreciate it!

Also, I decided to give this a try before I ordered a fuel pump, it has been over a week now and no problems yet. Hopefully the relay swap fixed it. Thanks for the info guys.

I am having the same type of problem...anyone no where these relays are on a 04 Vette. Are they under the hood or behind the kickpanel? I am going back to dink around with the car again today, but it is 100 miles away and I am trying to figure out everything I can before I go. Thanks all
