so i have a 90' hf with an ls vtec engine i built, forged internals if it matters, so my issue is i cant seem to figure out how to get it running, after building engine it was turbo and ran fine on a base map with id 1000ccs, didnt drive on street with it but around shop and in the yard, ran into money problem and sold all turbo accessorys and swap back to factory injectors. now it wont run unless i unplug the tps and it will start and run fine till it warms up then barley have any power to move. ive tested tps checks out good, 5vs going in .46 at idle and 4.6 at wot, any ideas anyone? only code it throughs is the tps code after i unplug it

 

Needs a tune. You could try using a stock ecu, that should at least start it.

 

o ya forgot to say im trying to run it off a stock p28, also have a chiped p28 with a stock b16 tune on it nethier will run it

 

Are you using stock OBD-0 crx injectors? If so, are you using an injector resistor box?

 

im using obd1 injectors, with no resistor

 

How sure are you that they are obd1? Did you use a multimeter to check their resistance?

 

not 100% the way i have it wired i can un plug the resistor and plug into a jumper i made that the grounds the wires, so i can go back and forth between injectors, ive tried both with the resistor and without, runs without resistor

 

tried swapping injectors with known good high impedance, ran with out resistor, made no difference. will not run at all with map pluged in, un plug map and it will start but dies after a few seconds unless u unplug tps as well, will stay running with both unpluged and but not running right
