ANOTHER no fuel issue

[TD or Not TD]

Well basically here is a list of things i have checked/ tried:1) made sure the fuel lines arent backwards2) i have spark3) pooring gas down a vacuum line makes it run fine then die after the fuel is gone.4) no codes(only 55)5) tried 2 ecu's6) used a multimeter on the injectors, getting some crazy readings while cranking7) fuel pump is working8) double checked the injector connectors9) grounds are bolted down tight

Things i think it could possibly be:

1) a really weak pump, even tho it seems to put out some good pressurea bad/missing resistor. i sent someone a pic of it and they told me it was the resistor, but i have went to a local shop and they had a ca swap there with something that looked like a resistor but less than half the size of the one i have. it seems as if there is supposed to be 2 boxes one resistor box and one other one which i am not sure what it does( and i dont have it)

2) one 2 wire connector off the fuse box doesnt plug into anything. i can take pics of anything if it helps at all.

3) all 4 injectors are stuck

you also have to remember this is in an 86 corolla GTS.

Goes back to the wiring job, dude. Something obviously isn't right and I just don't think it's a hardware issue.

whats what im thinking. what kind of signal am i supposed to get to the injectors... like 5v or 12v i dont remember what its supposed to be so i can properly test it.

The connector shows 12 volts.

Well i just double checked. i put the black prick on each side of the injector connector and the red prick of the multimeter to power and it started at like 9.xx and slowly dropped the longer i held it on there the more it dropped.

after that i put power to one side and ground to the other side of the injector and it clicked... so do i have a grounding issue? do i need to run a wire direct from each injector to ground?

or could it possibly be a bad resistor. im soo close to getting this thing running.

Besides your battery being a bit low on power, you don't have a major problem. What injector resistor are you using? I'm 690% sure you have a wiring issue and albeit a small one, it's an issue that needs to be addressed. Something is not hooked-up correctly and that is what's preventing your car from starting. This where familiarity with nissan wiring is a must when wiring a nissan eccs into another name brand car or else you'll have these little silly issues.

deffinately, i did more testing to try to help figure out the problem.

i ran power to the stripped wire on the injector and it fired on that cylinder. so i assume theres something that isnt right where the injector isnt getting power.

as for the resistor if its about 3-4'' lo silver and has 5 wires off of it(sorry im a nub at nissans) than its hooked up that i know of. but the person who did the wiring has it retaped so i didnt know if he messed with anything there.

is it possible to have a bad resistor? and is there a way to test it?

[TD or Not TD]

alright if someone can tell me where the resistor wire goes to... the line going in had no power. i ran a jumper wire to it and boom. fired right up..... what do i have to do it wire it properly.

im very excited now!

[TD or Not TD]

anyone? do i just have to wire it into the fuse box?

[Liquid_Neon]

you have a resistor box?

doesn't it have 4 in and four out?

When i put the low impedance i made my own resistors. see if u can get any continuity through that box.

i got the car running. i ran a power wire to the resistor box. it has 1 power wire and then one for each injector. the resistor wasnt getting any power so i am just wondering if there is a specific place i had to run the power wire too.

Congrats on getting the car to run! In order for this to be without power, something is still not hooked-up correctly. Make sure your wiringis done correctly before you go taking it for a test drive or else you'll be towing the car back to your spot with more issues.
