Good AFternoon TYF family,

I just wanted to update this thread and state that since the spider injection had been replaced, the truck lasted roughly 5 days before doing its intermittent crank but no start... Yikes!

Truck was diagnosed again for another bad fuel pump. Went ahead and warrantied out the ACDelco pump for another one. Free of charge on the pump and installation. No harm, no foul. The day after getting the new pump in, guess what happened.. BINGO!!! Intermittent no start.. Double yikes!

Was able to get it started the next morning and brought right back to the mechanic. Very nice down-to-earth older gentleman who is close to a family member, so I can't be too upset at him. I just wanted to trust my truck again to no longer decide when it wants to start or not.

Mechanic took his time this time and had it for 6 days. I told him no rush AT ALL. He finally found spliced wires along the fuel rail that were causing a short to the pump, not allowing it to prime on those random no starts. No charge. I would like to shout out east302 and exp500 for their knowledgeable takes. Very sharp members, who seemed to be suspecting an electric short to the pump all along. Thank you both for your very knowledgeable information and diagrams on this thread.

While it sucks to be out on money for the spider, fuel pump, and labor. It is only inevitable that these parts would need replaced down the road. No intentions on selling the truck.

It sure feels damn good to turn the key and hear the pump prime and love my truck again.

I apologize to anyone who may have had similar problems that read this thread and lead them to wrong ideas.

Long Live The GMT400

Glad it's finally resolved; that's gotta be a good feeling!

Hey TYF family,

I've got my first thread to post on a problem that I am having with my 1999 Chevy Tahoe 5.7L Vortec 173K miles. No check engine light, no codes, no misfires, and no loss of power.

Recently, (past 6 months) the truck has had a full tune-up, along with a fuel pump and fuel filter replacement. The problem started with a random no start 6 months ago. When I say random, it felt like the truck would give me no problems for 4-5 starts then after that 4th or 5th start it would just crank like there was no fuel. If I would let it sit for a few minutes, it would start hassle free and begin the whole process over again it felt like. I was recommended by a family friend to check the battery terminals (no issues there), replace the fuel pump and give it a tune-up. Did the tune-up first and that worked for a few months. Truck went 4-5 months without any issues, before it started to give me trouble starting again..

So, I moved on to the fuel pump and filter. Did the fuel pump about 3 weeks ago. ACDelco fuel pump and fuel filter done. The truck started for about 2 straight weeks with absolutely no issues again but, last weekend (Saturday) stalled in the driveway after running for about 3 minutes while I was helping my son fill up the tire on his bike. Got back in the truck and it fired right back up and I went about my way and did my errands for the day, no issues. The very next day (Sunday), I took it up to the corner gas station. Was hesitant to shut it off but I did. Came out of the gas station and it fired right up. As I was waiting to pull onto the main road out of the parking lot, the truck stalled again. I panicked, but the truck started right back up and made it back home with no issues.

That night I invested in a fuel pressure gauge (a little late, I know lol) and I was getting 60+ psi to the fuel rail when turning the key and 52-54 psi once it started and idled. All this week it has not stalled, but it has started its 4-5 starts then not want to start again unless you let it sit for a few minutes. I began to notice that when it would not start, I would have 0 psi and it would just crank. If I let it sit and swung the key from off to auxiliary on, the gauge may read 0 psi for a few swings, then would shoot up to 60 psi and I would be able to go full swing and have the truck fire right up!

Last night, the truck wouldn't start. I tried for an hour swinging the key off and on.. Nothing. The entire hour the gas pressure gauge never budged from 0 psi so, it feels like whatever the culprit is finally gave out. Also tried this morning when leaving for work and had the same ongoing issue as last night. It is sort of a sense of relief knowing that whatever this ongoing problem is, could finally show itself.

I am now being advised to look into the spider injection and fuel pressure regulator. Would anyone know how to diagnose the injector? I am so deep into this ongoing issue; I would just hate to replace those, and it be a band-aid fix like the other repairs have felt like.

Any past experience and 2 cents are extremely welcome, please.

I love this truck and just want to put my trust back in it.

Where do you find spare parts for your Tahoe. I have a 1999 GMC Yukon and have a difficult time finding both mechanical and Interior/body parts. Thanks

Good Morning,

I try to mostly buy new OEM parts for the truck, whether it be online or through a local ACDelco dealer. RockAuto.com is a great source for anything on the truck. You may even source interior parts or anything cosmetic for that matter, through your local junk yard. These trucks are becoming more scarce through the junk yards, but you should still find a few to source from.

Good luck on your finds and long live your GMT400!
