    99 Tahoe no start, got fuel and spark

    New pump was DOA. Only put out 20 psi. Returning and buying an entire assembly.

    99 Tahoe no start, got fuel and spark

    Okay, I got the tank out, tested pressure again at the pump, still only 4-5 pounds. Noticed the return line was not snapped on the pump from when the tank was installed a few weeks ago, odd. Anyway, I've got the hanger apart and I have the pump out but I can't seem to get the fuel feed line off...

    99 Tahoe no start, got fuel and spark

    well I finally got to get back under it and check the fuel pressure between the filter and the pump, and it shouldn't be any surprise but the pump is shot, its only putting out 4 pounds of pressure even after I prime it 10 times. so I'm gonna drain the fuel out and drop the tank. time to put a...

    99 Tahoe no start, got fuel and spark

    No, just bought it. It's been sitting for a year or so. I have already doubled checked the cap and etc.

    99 Tahoe no start, got fuel and spark

    I only had about 30 minutes to mess with it the other night, I did not have the right fitting I rigged up something, it leaked but I did see more than 10 psi before It leaked down, so when I get a chance to get under it with a better jerry rigged gauge I will look again. its def. getting some...

    99 Tahoe no start, got fuel and spark

    thanks or the reply, no my gauge does not have negative pressure and it has a peg. I only asked that because I've head it drain in the tank when the pump cycles on when I turn the key off. it doesn't do it all the time though. and the filter doesn't have an arrow but IIRC outlet was marked...

    99 Tahoe no start, got fuel and spark

    Tested fuel pressure, not getting any at all. Double checked I'm getting fuel to the gauge and tested another obs to make sure the gauge is working right. I'm getting fuel to the gauge, but not even managing to build even 1 psi. Pump is really loud too. I'm going to test pressure at the filter...

    rough idle, p0300 after FPR replacement 96 5.0 vortec

    Okay, I tested his fuel pressure, its all over the place. First few times it would only build 30 ish psi and drop down to 20 after the pump stopped running. After that it would jump to 55 every time but as soon as the pump primes to 55 it drops to either 50 or 42 and then slowly drops over 20...

    rough idle, p0300 after FPR replacement 96 5.0 vortec

    Just an update, he got the "new" spider in and all put back together and now his truck won't fire at all. It tries, but wont start. He's rebuilding the old spider soon or replacing it with the upgraded one, we found a deal. I have a fuel pressure gauge coming in and I'll check his pressure for...

    99 Tahoe no start, got fuel and spark

    Been a busy couple days, thought I'd update, verified that the regulator is fine. Don't have a pressure gauge yet, hopefully will arrive tomorrow. But o was monkeying around with trying to make one and whole I was connecting it, I noticed after sitting 3 days the truck has pretty strong pressure...

    99 Tahoe no start, got fuel and spark

    The only problem is it doesn't fire and then die, it doesn't try to fire at all. I figured if it was a passlock issue it would fire and then die instantly. EDIT: I forgot to add that all I know about this truck before I got it was she drove it home from work one day and the next day it wouldn't...

    99 Tahoe no start, got fuel and spark

    Yeah, mine is pretty much that loud. I'm also wondering back to a passlock issue. Someone told me in a group that theirs did the same thing, and the security light didn't flash on theirs either, but he had to do a relearn on his to get it to start. I may try that tomorrow. Don't have much else I...

    99 Tahoe no start, got fuel and spark

    Looks like you're right, so I need to apologize. I was frustrated. Plugs were great, timing is perfect, spark getting to plugs well. Finally said EFF it, and poured more than a tiny bit of gas in the TB and it busted right off 3 times. It's not getting any fuel. The filter is new. The pump is...

    99 Tahoe no start, got fuel and spark

    Verified that the coolant sensor is not the issue, and the security light is not flashing so it's not passlock. I'm gonna pull the plugs shortly and the dizzy cap. I've already checked the the cap is tight and not moving. It still sounds like it's not turning over fast enough. I put a magnetic...

    99 Tahoe no start, got fuel and spark

    I'm about to go work on the Tahoe. Will also be checking for a passlock problem. I delt with it once in my cousins 02 Chevy pickup. His would attempt to start though or start and then immediately die.

    99 Tahoe no start, got fuel and spark

    If fuel pressure was my problem it would at least pop or try to start when i use start fluid. Don't have a fuel pressure gauge til later this week but It doesn't do anything, it acts just like s no spark issue, and believe it or not, I have seen an engine run without a rotor. It was a Ford v6 in...

    99 Tahoe no start, got fuel and spark

    I should add that my scanner shows that it hasn't run the coolant sensor test yet, so idk. In fact it shows 48 codes not ran since codes cleared, and no codes current.

    99 Tahoe no start, got fuel and spark

    I checked on 3 plugs, 2 on passenger side and #1. I'm going to try unplugging the coolant sensor as well, I've read here that it can cause a no start situation, worth a shot.

    99 Tahoe no start, got fuel and spark

    I haven't pulled any plugs yet, got caught by the rain, but I pulled plug wires and they got excellent spark on the plug side. I saw a thread earlier where someone had such bad plugs they wouldn't fire at all, it's on the list of things to check. Any other ideas?

    99 Tahoe no start, got fuel and spark

    Trying to get my new Tahoe started. It's getting fuel pressure and excellent spark. I've tried a little start fluid in the TB but it still doesn't try to bust off, just spins. I swapped the ignition module and coil off a running truck and still getting good spark, but still no pop. The tech...

    rough idle, p0300 after FPR replacement 96 5.0 vortec

    Got the tires mounted on the Tahoe so it's sitting on its own weight. And now once I go get a starter hopefully it'll fire and run. To my knowledge nothing is wrong with it other than it needs a full tube up. Thanks for the advice on my dad's truck guys, I've relayed it all to him.

    rough idle, p0300 after FPR replacement 96 5.0 vortec

    To answer your question, I don't think it's a leaking poppet because it seems to be all four cylinders on the passenger side misfiring randomly. The main reason he's so stubborn about it is because he has access to nearly unlimited free parts from a junk yard, and he makes fairly good money so...

    rough idle, p0300 after FPR replacement 96 5.0 vortec

    It's my dad's truck, I've asked these questions for him. He's stubborn and doesn't believe it's a fuel problem. Please understand I have tools, like a fuel pressure gauge, but it only fits my f150. I've not been wrenching on trucks in a couple years due to circumstances I'm not going to explain...

    rough idle, p0300 after FPR replacement 96 5.0 vortec

    Well I fried the 351 in my f150, so from here on out he's gonna have to worry about his truck, I have to turn my attention to the new (to me) Tahoe. F150 getting parked til I can tear into it and rebuild. I'm bummed but still excited to be back in a Chevy. Can't wait to start turning wrenches on...

    I agree, but it's not my call.
