ummm...how do I check fuel pressure while 'accelerating' and what do u mean by 'condition of the main tank'?

You'd need to plumb up a fuel pressure guage. As for the condition of the main tank, I was referring to how much pressure or vacuum it is under.

 

check the fuel filter too!!

my bro bought a 91 caddy and the previous owner took my bro's $1700 offer because the previous owner said that there was probs in the fuel system. It was just a clogged filter. If theres impurities[sp?] around the fuel filter, the fuel filter will become saturated and clogged. Then the engine stops, and the impurities settle.

 

I have changed the Fuel Filter within the last six months...could still be bad?

i doubt its the fuel filter b/c releasing pressure in the fuel tank shouldn't help it start...change the pump and the filter adn it should work fine

 

Is it safe to buy a used pump?...because a new pump is outrageously expensive...but..if I buy a used pump am I just wasting my money. I looked around a while back and found a used one for $150 CAN...where as the new one was $450 CAN.

Any thoughts?

the fuel pump is an important part of a car and i wouldn't buy it used

one thing i do is when i'm not 100% positive of what is wrong i bring it to the dealer and tell them my symptons...they will diagnose the problem for free and you can then get a more professional opinion of what the problem is...it's likely that they know exactly what it is before they even do tests

 

A dealer will do something for free!? Really!?
Somehow never thought that possible...

I've asked everywhere...I've been told to check the following...

Fuel Pump
Fuel Pressure
Vapour Lock
Main Relay
Fuel Filter
Plugs Wires
Misc.

Anything else I should add to the list?

my dad also said that about my civic hatch (89). Relase the gas pressure by removing the gas cap and the replacing it. I have tons and tons of hissing when i open mine...But i've been told it's the main relay...i haven't replaced mine, don't really care...my car runs fine some days and ****ty others...

 

Maybe the gas cap thing is an "old Dad's tale" (Like an old wives tale just pertains to mechanical stuff). But hey it's worked for me a couple of times and I have no idea why? If anyone can explain why...please do!?
Anyone got any ideas of things I should add to my list above that could be causing this??
