it's having a starting issue that's pissing me off.. it cranks just fine.. so it's not the starter..
it feels like it's not getting enough fuel on start up ( this is bone stock btw)

I replaced :

plugs
wires
injectors
pump
filter (air and fuel)
cleaned maf/aic
replaced pcv..

still I have to give it a quick tap of gas at start up or it dies.. yes all my fittings are secure and no I don't have any vac leaks.. I checked about 12 times...

any ideas?

check voltage?
what kind of injection does it have. does it have an idle circuit?

once you get it running, does it stay running? any problems with it idling?

HMUSN · 04-18-2008, 09:29 PM

no idle issues at all.. once it starts it's just fine.. it's just that if I don't tap the gas (it's fuel injected) it wants to die at start up..(jumps around to 300-500 rpms then catches after a second) I mean just a little tap.. like a 1500 rpm rev on a stang.

try this.. before you start it, just turn the switch on for a few seconds before you try to crank it.. see if that does anything

the fuel pump is fine.. I can hear the buzz

someone on MM suggested the regulator so I'll have to check that

i say check voltage at the pump while cranking.

The regulator is a very good possiblity...

Can you get a cheap adjustable somewhere...Those work on the 3.8's right?

HMUSN · 04-18-2008, 09:44 PM

I think so.. I'll just get an OE replacement more than likely..
