Heavy D508

hey guys, bought the car off a buddy, not sure if this is any help but i have a GSR harness on my Z6, car cranks but wont start, im getting no spark and fuel pump does not turn on, i have a 255 lph fuel pump, and thing is loud, it worked before, until we took the motor back out, but it did had a z6 harness until my buddy gave it to me, i have tried 2 ecu, has a brand new main relay, but still tried with another and still nothing, didnt try a straight 12 volts to the pump, new to the honda electrical, im more of a toyota guy, but the del sol is fully built with eagle H rods, and big turbo, the car did ran and all that, tomorrow im getting another dizzy to check too, but was wondering what u guys thing, the car is also a 5spd not sure if that helps, and with both p28 ecu, pump still wont turn on

Does the starter crank the engine with the key in ON(III)?

Is the important G101 ground wire attached to the thermostat housing?

Heavy D508

yes starter cranks the motor, and i made sure all grounds are connected, a buddy of mine that knows about civics said the the relay vibrates when we have it on the on position, i think he said ur suppose to hear 2 clicks, but it does the first click, and then the second doesnt, and then it just vibrates, im also gonna change the harness to just make sure its that or not, and gonna get a 3rd ecu also, sucky thing is tho, car is not next to me and dont have a battery to test voltages, till tomorrow, i do have a DMM to test out things, and i will try to pull codes.

try replacing the relay if its not engaging.. thats waaay cheaper then trying to get another ecu, harness etc. main relays are common issue.

Is either 15A hood fuse 31 or 15A dash fuse 24 blown?

Heavy D508

which one is 24? last one i see is 32, i checked all the fuses, and they are fine, and i checked all the 15A and under the hood fuses too, im just waiting for my buddy to swing by with his battery, my other batteries are too big for this car

Former User

You'll find fuse box diagrams in the FAQs sticky. Many people miss dash fuse 24 because it's set off from the main group. It's also an SRS fuse.

Heavy D508

ok i just checked them and they are all fine, sorry for being late back to you with that, just been having problems, but i checked for codes and i got code 11

another thing, not sure if i mentioned i dont have spark either.

Heavy D508

ok, i got the fuel pump to work, but now im still getting no spark, found out the wire in the engine bay was spliced up and wasnt put back on right, so now it primes and works when cranking, but getting no spark.

i changed another dizzy with a working D16z6 that pulled into my drive way and drove off, and still no spark, i even used a ecu that works on another car that is being driven too, i get power to the dizzy, from the 2 cables that connects to the dizzy from the engine harness, but didnt check the harness that has over 5 wires for voltages, but if any one can help will greatly appreciated, now that my other project car which is my supra ended up having problems i need this car kinda asap

Any CEL codes?

Do the igniter input tests detailed in the service manual. You'll find a diagram in the FAQs sticky.

howmany lights turn on ,, when key is passed... u might have friend the harness if the car does now do the complete bulb check tred swapping harness yet?

I have a 93 del sol si D16Z6 auto which wouldn't start and it was the fuel pump 3 times in the past year. I think the first time it was the original pump the other 2 were replacement Autozone pumps. I was going to start a thread on it. I don't know if it was the workmanship (Airtex brand), ethanol gas, sea foam application, moisture in gas, rust in gas tank, electrical? I'm now good at checking main relays and grounds. In the del sol it's easy to change out the pump (seems easy now at least). I replaced the strainer and fuel filter the first time and Autozone replaces the pumps under warranty with no hassle. Makes me wonder if they know something is wrong with them. Maybe their cost basis is $10 and they sell them for $86. They can afford a few swap outs?

Heavy D508

after getting the fuel pump running theres no codes, i did get a code 11 which i posted up earlier, i will have to go to where the car is at since i towed it out of my place yesterday to a buddys house, but like i said i even changed a whole dizzy and nothing still but, im gonna check for ohms and voltages

Former User

Reread the CEL codes because code 11 is not a valid code. Did you do the input tests?

Heavy D508

i seen that 11 is a code 0 lol, i dont have the car here with me but ill have my buddy do it in a few

Former User

Code 11 in not a valid code for your car.

Heavy D508

well my friend said that the del sol has the same voltages as my others friend z6 with a p28 ecu in it just like mine, but only thing is i have a GSR harness, which i been told plenty of times that its all the same thing. he said he tested the wiring from the motor to the ecu starting from the DIZZY, and he said that he gets the same results when testing my other friend civic, already tried a z6 DIZZY that works and even a b18 dizzy and still nothing, just to see if it shoots spark but nothing, we also have about 5-6ecu to test and still nothing, checked pretty much all the fuses and they are fine, fuel pump works also.

last time when i there, i noticed that the relay clicks when starting, idk if thats normal

Heavy D508

would any one know the voltages for all the wires? i mainly need it for the dizzy, and ohms, i need to get this car running asap

Heavy D508

bump, any one know what are my voltages for the ecu are for all the pins? i want to see what im suppose to have for voltages, my dizzy is not shooting any sparks, i tested it with another z6 2 b18s dizzys and still nothing, any one knows why on the ecu pin B13 im only getting 8 volts, while my buddy 91 civic hatch is getting a full 12 volts, my battery is charged and still seems weird to be low, and the 91 hatch has a b18.

my buddy was testing the wires while cranking the motor and he said all the voltages goes to 0 when cranking, and this is for the dizzy, is this normal?

Click the Check Spark link in my signature.

Heavy D508

i did check, i used about 4 dizzy, and if all 4 aint sparking and about 5 ecu all work, some else is wrong. i checked for codes, and theres no codes, timing belt spints because i see the timing belt clearly cause theres no timing cover, ground is connected because im getting 12V from it, resistors are with-in spec even tho the dizzy looks like ****, and all other dizzys are in working order because they turned on other cars.

gonna try the 30 seconds starter to see what codes come up.

Former User

Also test for voltage getting to the distributor and the Yel/Grn wire for a short or open.

Heavy D508

i just wrote what the voltages were, im only getting 3 from the harness and 8 from the ecu, my friend is getting 12v on his b18 91 hatch.

also if i plug the B connector back to the ecu and test the ecu while the B connector is plugged in, i get back to 3 volts. about around 3.5

Heavy D508

also not sure if you read my post that i mentioned above, i took my whole dash apart, and lots of wires are spliced and cut, and i read that my ignition can be also a problem, what voltages should i be getting from the ignition, next time ill go back ill take pics

Former User

The ECU does not supply ANY voltage to the distributor, so I have no idea what you are testing there.

3V from the harness? What harness? What wire? How are you doing the measurement?
