now the car starts then dies immidately. only CEL im getting is injectors and ive changed them already and same thing still..anyone?

Steve

 

it doesnt even really start now...kinda starts but still dies none the less, has plenty of fuel, injectors possibly arnt spraying...wouldnt know why though. anyone?..heeeellp

 

do you have a resistor box hooked up?

DEF

 

nope this motor came out of a friends car and its a dpfi on a hf (yes i know, wtf) so i have no need for the box.

main relay.... swap it out for a friends one and put your in there the symptoms should be fixed and your friends car will have your problem

 

swapped them out a long time ago its still good its just like its not burning the fuel / runnin too rich, / injectors not spraying at all or somthing gettin enough spark to kill someone so cant be that....need to check ingitor which one is it on dpfi?

 

Walk through the whole motor install.

You needed to change out the ECU
You should be using the DPFI distributor.
The injectors are different from the MPFI one's AFAIK.
You also needed to do the DPFI to MPFI conversion, but the exact opposite.

 

did it all, it actually started one time and ran on its own and since then i havnt got it to start back up has to do with the injectors though i think, see i sprayed carb cleaner in it, and it started ...sorda, but i used real 'starter fuel" and it wouldnt even try to start so not sure on that part

 

Ignition switch

Yeah - have to open the butterfly in the TB when doing that.
It needs air to go in with the carb/starter stuff when you try to fire it that way.
Holding down the gas pedal should open the butterfly.


Have you pulled the plugs to see if they were wet after a few tries?

You could also pull the injectors, set them in a jar or something, and then try starting the car like that. You should see gas spit out. Actually, you would only need to pull the primary injector to test like that. I believe it's the lower of the two injectors. The secondary injector only works in higher RPM ranges or when the engine is under a load (basically only works when needed).

If the fuel is working, then you need to make sure you have good compression, spark, and air.

 

plugs are a little wet now, ima do some things when it cools down outside, its like 105 outside -_-;

 

thought u doing it in ur garage? anyway my car giving me problem too

 

haha what you do to your car this time

 

feeding it with too much fuel

 

alright its no longer a fuel problem (if it every was) it doesnt even try to start while spraying carb choke / ether...only error code im getting is injectors, but only after i try to start the car, otherwise its errorless..

to date:
spark plugs are fine (checked, all of them spark)
vacuum lines seem fine
compression : unknown

everything looks fine sept the injector error code, and ive swapped them out a few times to see if it was that and i take it, its not.

 

narrowed it down, when main relay is pluged in it doesnt try to start, when main relay is unplugged it tries / does for a sec or 2. and its not a bad main relay (already checked) so...anyone? (thinkin of a wiring thing ya know)

edit: followed the wire to the ignition switch, where would the ignition switch go to the ecu?
