hard starts once warmed??
when my car is cold, it starts very easy BUT once its warm i have to hold the key for like 5 sec, it turns over for a sec then stops then slowly cranks twice THEN starts :-\ i cleaned the rotor & cap, battery terminals but no luck...the battery is relocated in the trunk (red top optima) but the positive cable has about 3 1/2 feet of slack :-X also there is this lame push start button that was installed on my car when i got it. what should i do?
BTW my car isnt boosted anymore |

check your coolant temp sensor?

Re: hard starts once warmed??
wtf really? mine has been screwed up for as long as i can remember :( how would that effect startup?

Re: hard starts once warmed??
If the ecu thinks that the car is still cold, its gonna add fuel to the point where somtimes they can flood and foul your plugs. Thats no good on a hot motor.

Re: hard starts once warmed??
hmm...i have a lil temp gauge becuase the oem one is off, so what would the ecu think if i disconnect the signal wire?

Re: hard starts once warmed??
well is there any other way i can stop it besided buying a new sensor? i really want to put my car up for sale already :) you know how some people can be when shopping for a car, espesically when there not too handy with cars and get scared off pretty easily :-\

try checking your main relay. i noticed that when its cold i will herar the relay click and i wll get fuel presurre but after a while of driving if i shut it off to go into the store or something the relay will not click and it will be hella hot. afiter it cools down for a sec it will start up fine.

I just fixed my main relay yesterday as I was having the exact same problem. Take it out and re-heat all of the solder connections, should work fine. (you're supposed to de-solder and re-solder the connections, but reheating them so they flow again works just fine.)
If you don't know how to solder, bring it to radioshack and ask nicely, they'll usually do it. (I did when I worked there) |

My fix is just jumper the fuel pump wire from one of the key on sources that goes to the relay. I did it to both my EF's, otherwise a new main relay is about 28 bucks. Jeff |
