my car has been in storage for almost a year, i took it out a little while ago and the fuel pump died on me. i tryed running an external electric pump without a fuel pressure regulator and ended up with gas pouring out of the carb all over the engine. the good thing is it sort of kick started my siezed in-tank fuel pump, but the bad thing is ive had a really bad bogging upon acceleraction ever since that day. the last time i drove it home it was running like total garbage and i got a loud POP sound comeing from the engine bay and that was when i decided to take it off the road again. is it possible that the flooding i caused before, might have messed up the float setting? the engine is only a couple years old and has mabey 10,000km's on it tops, so theres no way its anything serious.

 

If you dont treat your gas when its stored that long I bet your fuel is nasty and you will need to drop the tank and flush out the old and put some fresh stuff in.The popping sound you heard is the engine not liking the fuel.. its not combustable anymore.The stuff I use is called stablizer,it keeps the fuel from gummin up.Hope you didnt plug up a jet in the carb as you might to rebuild it.

 

i dont think its bad fuel, because i was driveing it around for a few weeks before the fuel pump died. i also rebuilt the carb after and the only thing i forgot to check was the float level. are you 100% sure its bad gas from the symptoms? i drove it for quite a while even after this problem and it never got any better even when i filled it with 94 and put some gas treatment in a few times

 

Its hard to diagnose a vehicle without being there in person so I can say,Yes,I am not 100% sure its bad gas.if you installed a external pump and fuel poured out of the carb then I would say you blew out the needle/seat in the carb and would look into the carb again.if you rebuilt the carb after the external pump thing then you might want to recheck the float cause the level of fuel is very important to how it runs.If its too low you will get a lean mixture/to high and you can load up the plugs.

 

this weekend im probly going to tear the carb appart again and measure the float level this time. im also wondering if mabey the gas melted some of the RTV around the intake manifold on the front or back, i know gas does nasty things to RTV. i also noticed my last ignition coil melted for some reason, my new one might have got fried too, but i havent pulled the cap off yet. is it possible to test if my coil is putting out a steady 40,000 volts with a digital multimeter? or is that gona fry the hell out of it?

If the RTV was dry before fuel hit it,then I wouldnt be to worried about it unless you see oil leaking out of the area of where the fuel hit.Second,you have an HEI type distributor.(High Energy Ignition).The coil if I am correct is located in the distributor cap.The only way to check those outputs is by locating a KV tool it basically connects to the end of a plug wire where the plug connects.You can increase the gap that the spark jumps and maybe measure it.Check Matco/Snap-on etc.The only other thing is to make sure you have the correct voltage going to the distributor.Too much voltage will create problems.Also the coil sits on a rubber disk that usually comes with heat sink grease,and a new carbon button make sure those are in good shape.Dont use the multi-meter unless you want to by a new one.
