mrlilguy fuel pump

[Speed3Rookie]

Guys, if you are gonna mod your 3 get the internals or pump for insurance. Either of these are cheaper than the cost of an engine. Why chance it?

So could inadequate fuel delivery cause engine failure?

So as some of you may have read I had my engine replaced at 30K miles due to low compression in the #3 cylinder. I have occasionally had fuel cut symptoms, and what I swear was detonation sounds both before and after the engine replacement. Since mine is an early 07 model, I was concerned that the TSB concerning the weak high pressure fuel pump might apply to me, and that this might have caused my compression problem. I am still concerned about it because they replaced the engine, but not the fuel pump. If this could have caused the problem, then I'm at risk of destroying another engine. What do you guys think - should I press harder to get the fuel pump replaced if I verify that it's one of the weak ones built before March 26, 2007? Or should I not be concerned about it?

is the bulletin something that everyone should get checked out? i would assume its worth the time to just swing it by to get all the things in the past year checked out huh.....

 

[speed3driver]

really? I haven't noticed any issues with my car yet. I figured my mild mods are not a big deal. Dashhawk logs haven't shown a lack of fuel yet.

I have intake, catted dp, and ap beta. Future mods are FMIC. I'll be done with it then as far as power goes.

My car struggled without the pump and ran like a champ with it. My car has a few more mods than yours though.. I still recommend it, but i guess if all is well no need.

Hell yes. Make the dealer check your pump. It doesnt go by the cars production date either. It depends on when the pump was made. There are numbees that can be seen on the pump once removed. It is in the TSB what number range is bad. If my engine blew thats the first hing i would make them check!

im not even under warranty anymore....if the problem is directly linked to the....lets say broken or faulty fuel pump tsb....does this mean the problem should be covered? or is it only covered under mandatory recalls?

Are there any other advantages to the CP-E pump as opposed to the PG kit besides easiness of the install?

Not that i know of..

the most obvious advantage is if you order it, you'll get it in a respectable time frame.

but, as far as technical differences, yes, there are many.

that is one reason why it's so much money. is it overbuilt? probably! but it's certainly the best pump available.

i suggest you email cp-e about details.

we have pumps and pump internals sitting on the shelf right now. i'm not going to squat on orders, so i'd say i can commit to a 'respectable' time frame. our pump consistently puts out more pressure than the cp-e pump. i am not trashing the pump anyone else makes, but this is a proven bit of information by several of our customers who data log our pumps VS others. reliability wise, our pump is very good and has been since we moved to the newest version of the parts used. we have another kit in the works that is going to be, bar none, the best we or anyone else in my opinion has ever sold.

oh, the only reason i said that is because i've seen people on another mazdaspeedforum complaining about unreasonable wait times, that's all. no offense ; )

if i happen to see that type of thing pop up, like sanch's thread on the other forum, i'll let them know you guys are stocked.

oh yeah, don't get me wrong, we've had long lead times on them before. i can't believe the demand on them. they fly off the shelves faster than we can get new batches made! i am sure the current stock will be gone by friday in fact.

So the only options right now are fully build CP-E pump or the PG internals kit, right?
The install of the internals looks pretty straight forward, but there's no piece of mind in form of the lifetime warranty, right?
And what are the chances something might go wrong and what could go wrong during the install of the internals?

 

[Speed3Rookie]

^ ...you are taking chances just like any other performance part. If you think cp-e or pg for that matter will replace your engine IF the pump/internals cause engine failure you are sadly mistaken.
Use either at YOUR own risk.

i stopped building pumps in house. i don't like sitting on expensive cores and its simple enough with good tools, patience and mechanical understanding that the job can be done by ones self. if you install the internals wrong, worst case scenario is that the pump will seize and fail. this will NOT cause engine failure. i have been there, done that with some failed pumps or pumps not put together right. the car will go into "limp mode" via the computer and simply run poorly until the pump is replaced. i have never seen a motor blow from a bad pump install, bad pump assembly, etc. when you look at how the system works, you will see that the likelihood of that happening is pretty much nil.

Just ordered the internals. Thank you, Ken.

I have the pg internals...you'll love it.

check your email, you'll find a USPS delivery confirmation number within

 

[fructus]

Got it. Thank you.

 

[fructus]

Got the package in the mail. Thanks, Ken. Now to the hard part - the install. I'm a bit concerned about the fuel spillage. Does starting the car cold, removing the "blue circuit relay", and waiting until the car "dies" prevent it completely?
