I give up...

Maybe if it is blocked by something, like if the cat broke up and is clogged.

Something very similar to this happened to my dads 95 suburban, I believe the issue was something not being balanced on his engine. He isn't home from work yet or I would call him. He would have to floor it just to make it up a very small incline.

It is like the engine wants to stall. It starts sputtering and back fireing and surging every time I hit the gas. It is getting to the point where even if i floor it, nothing happens. It is really hard to explain. The rpms go up, but the engine gets no louder and it just pops and crackles and i stay about 15-20 mph. Especially after a stop sign or light because I have to hit the gas. If I have it in park, it all goes away. Would a transmission problem cause this?

[Duck Vader]

Once it warms up though, it seems to go away for some reason.

Also, where the muffler connect to the pipe between the muffler and cat, there is a build up of this white chalk like substance.

[Duck Vader]

They said its the fuel pump.

[Duck Vader]

The pressure kept going up and down. I am going to put in a new pump/filter and see if that solves it. What do you think?

[Duck Vader]

Also, should I get a fuel pressure regulator too?

[JagdStealth]

the car should have an FPR on it already

[Duck Vader]

i meant should i replace it?

I'd try one thing at a time..go with the fuel pump..see if it helps, if not go with the FPR as well.
Unless swapping the FPR is a huge pain? Then do 'em at the same time

You know many of us feel you on the car problems dude.
I just spent an extra 8 hours maybe the past 2 days COMPLETELY grinding away a lug nut/stud on my Conquest right front wheel to get the wheel off finally. (lugnut had come off 1/2" and then the wheel stud would just spin not attached from behind anymore, couldn't pull to re-tighten it up)
8 EXTRA hours just to ship someone their new rims.
let alone the dead Conquest

[Duck Vader]

Would an EXTREMELY bad exhaust cause fuel pressure problems or not? My downpipe is barely hanging onto my manifold.

[TajMan]

No it can't cause fuel PRESSURE problems.

I drove a VW Corrado I had once to a repair shop to pull broken stud WITH NO EXHAUST MANIFOLD ON THE HEAD AT ALL!

Sorry to hear that. I am glad I have not had to do something like that yet. I have been lucky enough to avoid such heartache as that.

OK, thanks, Just making sure. I am going to drop the tank this weekend and see what I can do.

I am also going to buy a fuel pump relay while I am at it.

[Duck Vader]

Would you guys trust a fuel pump assembly from autozone? I can get one for $230 that offers everything I think I need.

[Superjfly]

Don't see why not. I've had fairly good success with them on domestic vehicles.
Make sure you compare warranties also (Advance Auto, Napa, etc)

[Duck Vader]

I wont go to advance...i have had nothing but bad experiences with them. I know autozone is 1 year...and i have no idea about napa

[TajMan]

With a new part from them sure should be fine. Only once in a blue moon did I get a new part there that was bad new in the box. Then just take it back and swap it again. And you're always covered as long as their warranty lasts.
