Builds boost but no power

[britdog]

Okay my profile is up to date on what's installed on my car and this problem has been happening before I installed my gm maf when I would start to move forward clutch pedal not all the way out the stock boosy gauge would be around 1-3 psi and my after market one still in vac. Then the stock one will raise to 7+ depending on how fast I accelerate. But the aftermarketgsuge is still not in boost yet. The car has no power. In order for any boost at all I have to floor it and the stock gauge hits like max and I only see like +/-4 psi I've looked around all my piping to the front mount and sprayed it down with soapy water and haven't found anything the car also had been running rich but this was before I installed the gm maf

Have you actually done a boost leak test? Like actually bought/made a boost leak tester and pressurized the system with an air compressor?

I'm making one right now to check it

That'll be the best thing to do. Do one and report back.

And the stock boost gauge isnt accurate at all. Its an eletronic estimate reading from the ECU.

Have you checked your spark plugs ?? I had an issue of not making power it was due to a coil on plug set up. I rebuilt and replaced everything boost leak tested it for days. No spark no boost.

i dont think i should have a problem with the that i had just replaced with ngk wires and bpr7 plugs

okay im letting my tester dry cause i glued it just in case it pops off if pressure does get built up. but while its drying i plulled the plugs and wires everything looks good theres not many miles on wither the plugs or wires, i have them 4123 which i believe is correct

If spark plug wire order was wrong I've never had the car crank. So don't think that's your issue for sure .

If it did it would sound like a suby .

That too!

I think he was also saying it could be an ignition COIL issue?
But I agree if it was an ignition problem you'd hear it for sure.

Is it running smoothly, just no power?

He spoke about spark plug wire order so I thought it was save to assume that's what he was asking. But you have a point. Bad ignition coil and you'll notice it.

Okay so it started to run really bad and I decided to pull the wires to see what happens and I pulled the fuel injector clips an number 3 isn't firing

so injector 3 is not firing, that's the only one. Check the connection, if not possible bad injector. Can you plug any other injector plug onto it? If you do that and it works then it's the connection, if it doesn't then it's the injector.

 

[britdog]

Thanks didn't even think about that ill try here in a bit and see what happens

Right on with the no spark no boost everything was caused by the number 3 plug, thing was bad replaced it with a spare from the tool box and it ran perfect and it's boosting alot better thanks for all the help guys
