Just what it says. Ran fine all day. Stop by my work and then try to crank it. No go. Used diode tester on injector clips. No fire. Obf1 convertion.

 

is there no voltage, or there no ground through the ecu?

Injectors have a constant 12v with key on. Ecu grounds the circuit to fire injector.

What resistance injector did you use and with or without resistor box?

 

IM USING 850's. With a 2 bar map. Its only when the engine is hot when its cold it'll fire right up. If I unplug the resistor box for 10 min then crank it it'll fire up but die then ill hook it back up and it runs fine. The only code I'm gettin is 6 but other than that the car runs fine.

 

sounds liek your resistor box is going bad or the underhood fuse blew.

try some inline resistors from radio shack and take out the resistor box and see if that helps.

 

I figured that was it. Its the only thing I can come up with. My alternator fuse blew one day after I filled up with gas.

 

if its not your injector resistor, check the main relay. It supplies the power to the resistor/injectors

 

well today as im driving down the road i can her a click noise and every time it does it the car sputters and ---- and doesnt hold steady rpm it sounds from the main relay



i figured my MAP sensor is going bad...cause you have to keep hittin the gas to keep it running...when its cold...
but when its warm it idles smooth but still sputters when i hear that click noise

 

consult your service manual on how to test your main relay.

 

fp relay?

 

the fp relay is built into the main relay. the main relay is actually two relays in one.
I just did that to mine cause it's doin the same thing, but mine tested out just perfect. I'm still not conviced it's good though.

It does sound main relay though
