OkUm,,,, white firewall , " certified" digital speedo, ,,,,,, no Impala in that video
Sorry
It is not registering anything on the fuel pressure gauge at idle. I’m assuming that the lag when I hit the gas is connected to the fuel pressure issue.I wouldn't worry about the major lag until you get what used to be gasoline out of the tank.
What makes you say that the fuel pressure is still an issue? What is the fuel pressure at idle with the engine running?
I’ll do the fuel pump this weekend, I almost have the tank down to E. I put the brown gas in the video in case someone has the same symptoms, it can be a fix in lieu of draining a tank.arnoldsmind::
It's starting no problem. The Fuel pressure is still an issue.
I didn't go through the whole vid, but it's idling like ****. And about the Caprice vs. Impala SS thing, just look for the 'WX6' (or WX3 I really don't remember) trim I.D. on the trunk lid SPID. All Impala SSes are just basic Caprices, but with the upfit Impala SS trim level, just like you could get a stripper Biscayne or lil better Bel-Air various levels of options and chrome 60 years ago.
I recall you have past ptsd from a prior tank drop. Just get the car somewhere nobody can see your trepidation and finally finally just do it. Andwhy post a vid of brown gas? Just git that crud outta the tank already. And just change that MoFu fuel pump already. And finally git on wit the rest of it. It could be something else, but you already got the pump so just put it in already. And then throw more easier parts at it as called for.
Sorry it's 9 and past my bedtime. Keep checking in what's going on eh.
You need to fix your fuel pressure gauge/measurement/etc - it won't run without fuel pressure, since you've had the car running for multiple hours, it's getting at least 40(?) psi of fuel pressure - figure out the reason that it doesn't read on your fuel pressure gauge before changing the fuel pump. A new pump is not necessarily any better or will last any longer than the one that is in your car now.It is not registering anything on the fuel pressure gauge at idle.

I like this test.

The fuel pump may have been fine all along - By putting all the additives in the gas tank it might have made the liquid flammable enough to at least burn in the engine.
The lag could be fuel pressure related, but more likely due to the fact that the liquid that used to be gasoline is barely flammable.
Use your own judgement on the below from a safety standpoint...
Pour a small cup of the liquid from your gas tank on the driveway and light it (if it will light)
Now do the same with a small cup of fresh, known good gasoline
What has been the underlying issues?There are many many cases of guys with LT1s here that have fuel delivery issues and their cars were still running at pressures of 20 and below.
I second that statement. Impala's never came in white. Impala's did not have the green silicone hoses. Impala's did not have the yellow trunk release button on the left side of the steering column. Also the drivers door panel shown in that video is from a 1991-1993 Caprice and is NOT an Impala SS door panel. Clearly the vehicle is a 9C1 police vehicle which was partially updated with Impala parts but for 100% sure it is NOT an Impala SS! Sorry but 95wagon is correct on what he noticed.Um,,,, white firewall , " certified" digital speedo, ,,,,,, no Impala in that video

I don't think that was in question. I'm not disputing the model. I said that 2 videos ago. AI second that statement. Impala's never came in white. Impala's did not have the green silicone hoses.

10 years. Last registration is from 2012How long had this car been sitting before you started working on it?
I’m lazy bro, and the car is 40 miles away from where I live. It’s not exactly convenient.This thread is like a bad fever dream. My car idles line ****, has no fuel pressure and bogs down when I press the accelerator. Drop the tank, clean it out and replace the fuel pump. No one should ever dance around a problem for this long. Get it done.
You will be the 1st one I thank if the Fuel Pump solves the problem. And the 1st one I’ll ask for help if it doesn’t.This thread is like a bad fever dream.

This is not a weekend project. I want to get it started so it can be smogged and sold.10 years
Yeah, you might have lead with that .
I 'm changing my recommendation
Pull the tank, have it pressure washed or steam cleaned
Change the pump , sender, everything inside
Take the fuel rail off ,
Get the injectors cleaned and tested
Have the rails cleaned inside, change the schrader valve , change all the o rings.
If you skip this stuff, best is it will be problematic , worst the car may burn down
