Ive been on here for months testing and switching parts and it still does the same thing...it turns over and all four injectors fire once then nothing...


Its a D16a6 basicly stock now besides exhaust, fuel pump is good, 35lbs to the rail, all the injectors are firing but only once, no codes, brand new distributor not a reman.,tried 3 different ecu's, the timing is dead on, both injector resistor boxes I got tested good, both main relays I have tested good also, Ive gone through the dpfi to mpfi wiring like ten times everything goes to the pins theyre supposed to on the ecu.

( I know people like to rip posts apart so when I say "both" I dont mean I have two on the car it means I have spares and duplicates of almost all my parts)

when you turn the key to "ON", does the Check Engine Light come on for 2 seconds and then go off? do you have the ground wires connected at the thermostat housing?

also try your water temp sensor and your air intake temp sensor those manage injector pulse timing (as far as i know) the temp sensor went out on me and it sounds like your having teh same problem... new sensor problem solved (for me)

that was my next stop was the iat / ta sensor is there anyway to clean em or just replace it? but the weird thing is I had a JRSC on the car and then switched back to the stock intake to see if something on the charger was bad.they both had sensors on em I hope they arent both bad..thanks... yeah the thermostat ground is hooked and yeah the check engine light goes on then off...thats why Im goin nuts everything should be workin hahaha

how would I test the intake air temp sensor??? and has anyone else heard that about the water temp sensor?
