I don't really understand too much from the way you worded it. but try this n lmk...

Turn the key all the way to the on position without cranking it over like 3 times to pump fuel. Then try n start it and see if it starts right up. My ek does the same thing but i didn't try n figure it out yet cuz im lazy lol

I'd recommend changing your fuel filter. And see if that does it.

yaa my bad its alil confusin to me too lol wen i start it up it turns on and turns off every mornin the only way to keep it on is to push the gas to about 2 or 3 rpms and keep it there for bout 10 to 15 mins until i can let off the gas and it wuld stay on

[LS/Vtec]

try priming it like i said n see if that works. I'd do a tune up. Should fix it.

[lsvic69]

ya ya i tryed that also it has no prob startin up jus stayin on but im def gonna get that tune up prolly next week hopefully that wuld fix the problem culd it b the ecu cuz its not producin the rite amount of fuel it need or mayb the fuel pump to small cuz it the stock one for a single cam vtec?!

lol nigga i aint the only one

your problem is the ecu, the ect compensation table. get a P75 ecu, your problem will be fix and you will get more power. don't know why you running an ls on a 1.6 vtec ecu. The ect compensation table is a scale the ecu uses to enrich the fuel while the coolant temperature is low, meaning the ecu will keep the mixture rich so the car could idle while the coolant temperature is low, ones it gets to operation temperature it will bring it down. just like the choke on carbs

[lsvic69]

ya i baught a p75 that was chipped but that didnt work out n then i tryed to make its stock but that also didnt work out lol so i just stayed wit my p28 but will def invest in a p75 thanks dude but on ore quest i plan on getin a tune n a chip put in it wuld it b better and get more power out of a chiped p28 or a chipped p75 for an ls motor?!

[panch]

well you need someone to adjust the ect tables. that's a 30 sec process

That is a good question and now is the right time to bring that myth to and end. ECUs don't make power, they are all the same, some have vtec, some don't, some are automatic some are manual, that is the only difference... you could get an automatic P75 and put IAB control for GSR motors, add vtec control, and also make it manual. So in reality they are all the same.they just have different functions but you can add all that your self

[lsvic69]

Ohhhhh ok dude thanks a lot for all the help. I suld b getin da tune next week appreciate da help
