kenz240z Posted March 25, 2011 Share #13 Posted March 25, 2011 If you still have the electric pump that is mounted back by the fuel tank, open it up and check the filter inside it. I'll bet it is getting clogged with debris from the tank. Ask me how I know... Link to comment Share on other sites More sharing options...
xplosiveg06 Posted March 25, 2011 Author Share #14 Posted March 25, 2011 i never had the chance to drive it before the fuel pump was removed. electric fuel pump in the rear is completely removed. only filter is the one under the hood before the mechanical pump Link to comment Share on other sites More sharing options...
Darrel Posted March 25, 2011 Share #15 Posted March 25, 2011 Time to start to diagnose this checking easy things first without throwing any money into it.Kenny and I have been through this.Replace the filter up front.Bring a floor jack and tools to unhook the fuel line by the tank, along with an air tank and blow nozzle if you have one. Go out for a spirited drive so that the car will die out. Pull over, raise the car up enough that you can blow through the fuel hose(TAKE THE GAS CAP OFF FIRST). This will clear any debris away from the fuel pick up line inside the tank.Put it back together then go for a drive again. Then see how long it takes to bog down again. If it bogs down again, repeat. This will tell you what is going on before having to drop the tank.This is that I did on my '73 with round tops that had sat for 14 yrs before I bought it. I put a 2.8 engine in, kept the electric pump, put a filter before the electric pump until I get the hoses for the tank and drop it to clean it out properly. My tank had a lot of varnish inside from sitting 14 yrs. While on the road course, it would constantly clog the fuel pick up after sloshing around and loosening up the debris. I still use the electric pump, especially at the track as the mechanical pump isn't enough for track driving with a 2.8. Link to comment Share on other sites More sharing options...
xplosiveg06 Posted April 4, 2011 Author Share #16 Posted April 4, 2011 it got to the point where it wouldnt start anymore. i changed the fuel filter up front and it starts and idles but now with off idle hesitation. the car seems to run smooth after you get it above a certain rpm. i pulled the plugs today and i will be replacing them. they looks pretty carbon fouled.

xplosiveg06 Posted April 5, 2011 Author Share #18 Posted April 5, 2011 (edited) just changed the plugs to brand new ngk g-force gs. car sounds like it runs a little smoother, but it still has a off idle hesitation. EDIT: hesitation was caused by the distributor cap being unaligned haha. looks like the complete cause of my problem is alot of debris coming from my gas tank. looks like im going to need to carry a few extra fuel filters with me when im driving around until all the debris empties from the tank . thanks for the help everyone Edited April 5, 2011 by xplosiveg06 Link to comment Share on other sites More sharing options...
5thhorsemann Posted April 5, 2011 Share #19 Posted April 5, 2011 Why not drain the tank, that will get rid of the bulk of the trash inside. Link to comment Share on other sites More sharing options...
