i have a 95 240 se. i put a turbonetics turbo kit and after installing the car wont start. it just try to start and when i put a little gas it will die.i have spark, the timing is right. i check the injectors and their good. what else is there to check? i did the auto to manual swap also but i didn't change the ecu. is it posible the car wont start cause i have an auto ecu?any feedback will be greatly appreciated.

Auto and manual TPS's are different too. Make sure you've swapped those sensors. I'm pretty sure you need a manual ECU though. Someone back me up on this

people swap manual ecu for auto all the time for it not having a speed limiter and having a slightly higher revlimit.and im pretty sure thoes guys dont have to swap tps.so that shouldnt be an issue.

TPS's have to be swapped, that's a fact. They are different. Although, I always thought the speed limiter was a sensor located on the transmission? You sure of this?

yeah, im sure that auto ecu eliminates the speed cut. do a search if you want to know for sure.hmm i coulda sworn ive read that its a straight swap, meaning just replace the ecu's and be done with it. but i guess im wrong about that.

the car started today for about 5 minutes then it died. i don't know if there is a relation this but every time i try starting the car i get so much pressure on my gas tank. i have to wait for a couple of hours before it will start again and it will only stay on for a couple of minutes.

You may have put your maf on backwards or not hooked it back up.

is the gas cap working? is the carbon canister hooked up? the hardline that runs from the fuel tank to the front of the engine bay capped off?

what you say the plugs go bad do you mean they become gas fouled and are destroyed...or do you mean that they become sooted up????

Just too clear things up, you don't need to swap anything electrical when it comes to the auto to 5 spd swap. But if you did happen to do a 5 spd shop make sure that the jumper for the neutral safety switch is hooked up.

Exact symptoms of bad timing. Red hot exhaust, fouling plugs from running rich, and bad ideling. Is it a rough idle or just really low one?

EDIT: Nevermind. It runs fine now?

rough idle. i was messing with the distributor on the idling but the car will stay on only if you turn the distributor clockwise all the way. i checked my timing chain and it's all in the right marks.

You may be one tooth off with your distributor, I am not sure if you pulled it at all. also do you have any boost leaks, you can check by pressurising the system with an air pump.

i redone the distributor, the car has a little rough idle but it doesn't die and the exhaust doesn't get red hot. but the car smokes a lot. i checked my compression i get 180, 185,185,183. why is the car smoking a lot???

what color is the smoke? if it's blue, expect your seals at the turbo to have gone south.

black and sometimes white. the turbo is brand new. i have the turbonetics turbo kit. the engine is newly rebuilt from top to bottom. new seals on everything. i am using stock injectors cause everytime i use their injectors the car gets flooded, i think it is stuck open. i have to return it to turbonetics. and i use new o-rings everytime i put the injectors.

Black smoke means you're running pretty rich. Whiteish blue smoke means you're burning oil, and straight white smoke is coolant.

Did you happen to install a walbro fuel pump with the kit? It is possible that your fpr may have crapped out. Some people experience this with the high pressure walbro pumps.

If you can try driving alittle bit...that would help in this process. If there is white smoke caused by coolant you could smell it. If ecu has been powered down for a while it needs to relearn how to operate, but don't make it do something its not wanting to do!
