most informative post ever.
i dont know what type of motor you have, who did the wiring, if you have spark, if you have fuel, if its timed correctly.

how can i help you if you arent helping yourself. search brobeans. or get on that flame suit.

[norcals13]

My bad I got spark and fuel did the wires my self im running a blacktop s13 I'm using a 400cca battery is that enough?

[eli-s13]

check the fuel line to make sure they are rite I just spent all night checking everything to finally figure out they were backwards. The line with the fuel filter goes to the lower and the return line goes to the fpr.

[norcals13]

Yea fpr goea to the one to the tank and filter to the one that is by the intake manifold rite

[eli-s13]

Yeah sounds like you got it rite well i guess check for spark on every cylinder and check each injector. You can ground out the black wire of each injector and listen for a click to see if it working. Other than that check the cas.

[norcals13]

Ok thanx I would try that can I just pull the fuel rail with injectors and crank it see if I have gas in all?

[slider2828]

Did you mess with the timing at all? Did you pull out the CAS? Check for spark.... Fuel you can check by just putting removing the rail and crank, but you can pull the plugs and just smell it....

[norcals13]

Got spark I only check on one plug tho I change the spark plugs before I put it in didn't mess with the timing or the cas

[norcals13]

Another thing I remember I crank it a couple of times and my lights got dime

[norcals13]

The l lil ground wire that comes with the alternator bunch bolts on the alternator casing rite?

[slider2828]

Say that last sentence again?

[norcals13]

There's a cable by the positive on the alternator it grounds on the same alternator rite

[slider2828]

If I remember there was a plug, and 2 wires... One positive one negative. I think the negative had 2 wires onto one screw.

[norcals13]

Mine has power and one ground that bolts to the case

[slider2828]

There is also something that plugs into the alternator..... Its not just 2 wires.

[norcals13]

Mine has power and one ground that bolts to the case

[slider2828]

Take a picture of the back of the alternator

[norcals13]

Yea is the harness for the alternator the positive and a lil wire that I believe bolt to the alternator case

[norcals13]

I don't know how to put pics on here

[norcals13]

U from sf my car is in hayward working on it in my cousins house, bad thing is ill be there till wednesday:(

[wangan_cruiser]

I didnt get what u were saying all along

[norcals13]

Need help car not starting check spark and fuel is there

[norcals13]

Crannk the car twice and the battery got low and battery light came on

[wangan_cruiser]

Crannk the car twice and the battery got low and battery light came on

the more you crank the battery the more it loses the charge. you need to have a full charge battery to make it start.

but if you have spark and fuel there then most likely it is your timing.

if it still dont start just report back. i could probably help you

[norcals13]

Ok kool thanx ill be on hayward Wednesday working on it ill let u know if u could help me that would be really good I can hook u up with cheep double dins the thing is I'm trying to get it running before april cuz ill be leaving to the military thanx

[wangan_cruiser]

I meant help you over the net lol mah bad

[slider2828]

Check for ECU Codes... Man how did we forget about this.... make sure you are clear....

[norcals13]

U check for codes the same as the regular 240 ecu rite?

[norcals13]

And yea any help would be really appreciated

[slider2828]

yup.............................

[wangan_cruiser]

yea its the same except when you turn on the ign switch then you turn the screw clockwise hold it for 2 secs i believe then turn it back.

here some codes for you.


CU fault codes

Long Flash - 0.6 seconds on (the first digit)
Short Flash - 0.3 seconds on (the second digit)
Long Gap - 2.1 seconds off (used between codes)
Short Gap - 0.9 seconds off (used between digits)

There are two digits in each code. Count the long flashes, then the short flashes (only count how many times the light is ON) and you'll have a 2 digit code. These codes are covered in the service manual.

Code Meaning
11 - Camshaft Position Sensor
12 - Air Flow Meter
13 - Coolant Temperature Sensor
14 - Vehicle Speed Sensor
21 - Ignition Signal
25 - IACV - AAC Valve
26 - Boost Pressure Sensor
31 - ECM Fault
32 - Exhaust Gas Recirculation System
33 - Front EGO Sensor (O2-1 Sensor)
34 - Knock Sensor
35 - EGR Temperature Sensor
36 - EGR BPT Valve
37 - Closed Loop System
41 - Intake Air Temperature Sensor
43 - Throttle Position Sensor
54 - Signal from Auto Transmission
55 - Other Malfunction. CONSULT Terminal Required
63 - Cylinder 6 Misfire (?)
64 - Cylinder 5 Misfire (?)
65 - Cylinder 4 Misfire
66 - Cylinder 3 Misfire
67 - Cylinder 2 Misfire
68 - Cylinder 1 Misfire
71 - Random Misfire
72 - TW Catalyst System
76 - Fuel Injection System
77 - Rear EGO Sensor (O2-2)
82 - Crank Position Sensor
84 - Automatic Transmission Diagnostic Comms Line
95 - Crank Position Cog
98 - Coolant Temperature Sensor
103 - Park/Neutral Switch
105 - EGR Solenoid
111 - Inhibitor Switch
112 - Automatic Transmission Speed Sensor
113 - Automatic Transmission 1st Signal
114 - Automatic Transmission 2nd Signal
115 - Automatic Transmission 3rd Signal
116 - Automatic Transmission 4th Signal
118 - Automatic Transmission Shift Solenoid Valve A
121 - Automatic Transmission Shift Solenoid Valve B

Kool so turn the ign on first turn the screw clockwise all the way hold it for 2 sec then turn it back to the original position and the light would flash the code rite

[norcals13]

Quick ? Does the ecu have to be bolted to the chassi to be grounded could that be the problem cuz somebody told me that???

[slider2828]

No......................
