It was the fuel pump or sending unit. He opted to buy the entire assembly. We tested the fuel pressure and it was zilch. Got the new assembly in and she fired right up.

Update.....we changed the fuel filter, and it starts now, but dies rather quickly. Won't take any throttle at all. Unplugged the MAF and the same thing. Seemed to actually start better with MAF...

It doesn't bog, but the valves ping bad at hard throttle.

175XXX, and we've changed the plugs a few times. I have had one coil pack go bad. I'm wondering if they all could be going bad. They are all original except for the one i had to change out. It's...

Generic and/or multiple misfire code. Not cylinder specific. Where to even start. lol 01 GMLS

Sorry just noticed the terrible spelling in the header.

Going to change the fuel filter this weekend. Haven't been able to get to it yet. Thanks and I'll keep you updated.

Thanks guys I will try all those. You can hear the pump when you turn the key on....so gonna start with the filter.

Jay we can hear the fuel pump when we turn the key on..which is weird because I have an 01 as well but can't hear it. I think the previous owners replaced this pump so it's aftermarket.

2001 GM..Brothers car. He stoped and got gas today and then maybe 10 minutes later he stopped at a stop sign and when he accelerated she started to shudder and then totally died. Now she will turn...

Ill try premium for sure. And at least a compression test. Thanks guys

01 MGM. 170xxx Some slight pinging at decent throttle. Extreme pinging and tons of blue smoke on WOT. I've read around, and haven't done a compression test yet. Just getting some ideas. And if it is...

It was the smaller wheels causing it. Come to find out, one wheel on the rear is a 15" and the other a 16". My fault for not checking more closely when I bought the car. Found that out when they went...

So if I turn the TC in the morning it should be good until I get to the shop?

I was thinking that. No sign of anything until we put them on. Getting two 16'' rears tomorrow.

This just started today. Now I have temporarily put 15'' wheels on the rear until tomorrow when I can get 2 new tires. Could that be causing it? Heard someone say the ABS sensor could be...

Gonna be my next stop. It's nothing that seems to be a problem other than the drop in revs when in reverse.

Well it's already on springs. Not sure if I want to go back to it. Why would you chose to have it IYO?

My GM is used..and someone removed the AS.....just wondering if it's possible to stop the warning from coming on.

Cleaned the MAF and it hasn't stalled since. Idle still drops pretty low but it hasn't shut off.

I see them for with and w/o handling package. And IYO should I change the complete assembly or just the bushings and the ball joints?

She's been idling very low when I put her in reverse and today she stalled completely.

Well...ordered a service manual cd from ebay..this thing is awesome so far and i just dove into it. Here is what it says about coolant for my 01.

When adding engine coolant, use a 50/50 mixture...

I'm not confident enough in my skills for a jmod....maybe I can find someone nearby that I trust to work on it.

Tonight she wanted to slip a bit with cruise control on and in OD. So fluid change next week. Hopefully that's all she needs.

i dont brake two footed. i havent checked the flickering....i will scope that out
