#96 of 206 Fuel Pressure Regulator - 2004 Chevy Suburban
Jan 01, 2010 (1:05 pm)
I have a 5.3 chevy suburban and when I try and turn if over it seems to crank, but won't fire right away. Once I get it started, it runs out fine...I noticed also if I just turn the key to the run position and not start it right away and then turn it to the start position it pops right away.
I had it in the shop getting the tires replaced and asked the mechanic and he said probably a fuel pressure regulator. he popped the cover off manifold and was trying to locate it, but after a few minutes he gave up. Does anyone know where the fuel pressure regulator would be located for a 2004 chevy suburban with a 5.3 ltr V8?

check fuel pump or clogged filter, many issues w/pumps.
#98 of 206 '03 5.3L Suburban Misfiring codes,poor mpg

Hello, my burb just started acting up on Sat. morning here in MN. very cold -30 temp. It was running rough and I was 200 miles from home. Brought to a small shop and he put on scanner and said #2,4,6,and 8 cylinders misfiring but didn't have time to go any further. I made it home but was getting less than 8 mpg instead of 16. Any ideas of what would cause this condition. Thank you.

That's all of the cylinders on one bank/head of the 'V'.
I'd suspect head gasket, intake manifold gasket, or maybe something messed with the sparkplug wires on that side of the engine.

I drove it today after being park in heated shop and still the same. A service manager at a local GM dealer said it might be the intake gasket. Another guy I know works at a Ford dealership said it would be best to put it on a GM scanner to monitor all the functions, which I gather is more than just getting error code readings. Hopefully, I'll find out more in the next couple of days. If it is the intake manifold gasket, I have read in other posts that there are different qualities of gaskets(one said the orange was is the better)? I know I am getting ahead of my self but, are there other things that should be done at the same time if that is my next step. BTW, it has 130K. Thanks.

One thing that hasn't been brought up on these misfire codes ( the dreaded p300 especially) is a faulty egr valve. I've had 3 different gm's and every time the rough idle was either the maf sensor or the egr valve.

I just replaced intake manifold gaskets and got the rough idle thing going on too. I pulled the connector out of the egr valve and nothing happened!. Is that a good sign that it is not working? Sounds like it to me. I'm also going to check the new wires for shorting paths also. That would be bad. The car ran well before I replaced the Intake manifold gaskets. I must have screwed something up. When you make a change and something is different, that is valid data and it should not be ignored. Lesson learned. I'll post my findings when I learn what went wrong.

HI. did you ever find out what was wrong with 2009 Sub? I have 2009 Tahoe and it has stalled on me 5 different times. Once at a stop sign and the rest driving down the road. No engine lights come on. I have been able to start it back up each time. Of course I brought it to the dealership and they do not know what is wrong. Since they hooked it up to the computer and it showed nothing wrong they cannot fix it. Please let me know any info. Thanks!

I have a 95 burb with the 5.7L. It tends to bog and want to stall when I try to accelerate from a stop. If it is already moving, it usually accelerates just fine. I have replaced the ignition control module, ignition coil, oxygen sensor, and fuel filter. The plugs and wires were replaced about 30k miles ago. I figure it could be the fuel pressure regulator, fuel pump relay, or possibly the intake manifold gasket. Any advice or experience with diagnosing this issue? I do have oil on and around the intake manifold and valve covers. I know the oil could easily just be from bad valve cover gaskets and is an easy enough replacement. Could the manifold absolute pressue sensor contribute to this rough running/acceleration issue? I don't know much about MAP sensors, so I do not know how much they affect fuel/air mixture and delivery. Any insight would be much appreciated. The model I own has TBI, so it looks like the fuel pressure regulator is located within the throttle body assembly, from the way the part looks. Has anyone with an older, TBI model replaced their FPR?
