i used all the original harness and im using a PG7 ecu. turn the key, fuel pump works and it does get spark.

in fact it starts... just shuts right off immediately, i took off the fuel rail, held the injectors and tried to start and the injectors only spray ONCE. if i turn the car off completely and try again it will spray again only ONCE.

what could be causing my injectors to only spray once? ive checked all the grounds that i can think of ( VC, tranny, thermostat ) and nothing.

 

maybe timing is off?

 

change the ecu

 

could that possibly be the problem?

 

Ya it's probably the ecu. I would use the PR4 ecu.

 

it should still start but just wont run the same as the pr4,Only one injector is firing?

 

All four fire, but only once.

 

swap a pr4 in there man

 

might be your injectors,no code 43,or injector code?

 

try the injectors! my friend went through the same and he did many things to it but never changed the injectors...... when we change the injectors it started right away!! also check all your grounds!! specially the one on the termo housin!!!!

 

up!! still need help. i dont have much time to ponder around and look to find the problem.. just need things to go straight for lol



no codes, checked all grounds, redid dizzy wiring. only thing i havent done is try a new set of injectors.... but could it really be injectors? even though it sprays once

 

injectors might be the problem i had same problem cuz i bought obd2 injectors when i needed obd0 injectors because of the resister box try the injectors the right ones

 

changed injectors same issue.... eh wtf is wrong with this thing

 

today i changed injectors to another set. changed the ecu to a pr4. replaced the main relay, DOUBLE checked all the grounds, and redid the OBDo to OBD1 dizzy plug conversion and still the same problem...


when it starts for its few seconds its sounds ALOT better than before, but it still shuts off after starting...

 

are you running OBD0? what distributor is on it? OBD0 ECU requires the use of OBD0 distributor - OBD1 distributor will not work
