So i did a turbo install on my 94 civic hatch SOHC about 10000 ago every things great other than some time it wont start on a hill unless i crank it for 5 min and some time after i drive it for a while, stop then try to start it again it takes 5 min for it to start again.

sounds like its not getting fuel, now i put bigger injectors, should i get a better fuel pump to make up for that? could that be my problem?

What do you think? You upgraded injectors but not the pump? Are you using any kind of engine management?

slipyoke

yeah we tuned it on chrome. witch is why i didnt think it could be fuel pump this whole time.

When was the last tune up?

Any CEL codes?

When it won't start, does the fuel pump prime? Is there bright white spark at the plugs?

slipyoke

tune up was 10,000 ago pulled the cap and rotor it all checks out, spark plugs are firing hot.

no codes

i did pull the idle air control valve because it had a weird idle an cleaned it up, helped the idle but not sure yet if it had anything to do with the won't start problem.

^When it won't start, right?

Pump prime?

Does the CEL work?

slipyoke

hmmm will look into that

i have a HUNGRY as hell d16 that if i just try to start it. takes up to 5 min of cranking unless i have it at WOT befor i try to start it.

i dodn't know if honda uses a different Injector pules pattern for starting but if it does you may be over fueling at startup

if it starts out at a kind of bog/underload sound when it fire it's too much fuel.
if it starts up and the motor races (say alot higher then times when it starts right up with No problems) i would say it's lean.

also When was the last time you put in a fuel filter. and when/if you do a fuel filter remember to dump out the fuel into a CLEAN clear glass containor (pour from the inlet side A.K.A the line from the pump) so you can see if you have a ton of crap in there.
when i got my last car i did this and found out i had a TON of rust in the tank.

slipyoke

Yeah when it starts it rpms high, so it must be running lean.

i was going to change the filter but it shows no signs of a bad filter (should do it anyway though)

Solster

if you don't have a fuel pressure gauge on your fuel system get one.
it's a big help.

also the fuel filter can cuase a lean condition as it will restrict the flow of fuel to the injectors.
the bad news is sence you didn't upgrade the fuelpump when you tuned it there is a good chance if the fuel pump is going out the tune will be WAY off when you get a better pump

Oh thats awesome.... thanks for the info

That shouldn't be an issue if you were the tuner.
