have an 89 crx si 90ls block 94 gsr head have 94 gsr dizzy have obd0-obd1 jumper for ecu n dizzy has 450 injecters si harness with resistor box has skunk 2 intake manifold n68 ml throttle body with the electronic map sensor gettin no fuel or spark using p28 obd1 ecu

 

Ground on theremostat housing?

 

could be a ton of things.. fuel pump turning on at all? Most likely a bad ground.

btw.. 450 injectors? boosted??

 

was boooosted. some one told me need to take resister box off? all the grounds are good.

 

If you have OBD1 or OBD2 injectors then you don't need the resistor box

 

are they dsm 450's then u need the resistor box. if they are saturated take it off. sounds like a bad ground. cheak the thermostat and all the other grounds like valvecover,and tranny.

 

i checked the grounds fuel pump is not coming n n no spark

 

thanx for the replys wasnt gettin power to the ecu new jumper haness nplug pins werent seating right had to push them all in with a test light ...... but thanx everyone
