just installed SR NOT RUNNING!!!!! HELP

[707]

ok guys im having the same problem as a bunch of other people but here goes... I just installed my motor, its turning over, has spark, has fuel, has MAF power but still not starting. could this be the CAS??? the plug is a little messed up because the car that had it was crashed. how can i test it?

sorry if this was already posted, no time to search thanks in advance

Is the ECU throwing any error codes?

[707]

i havent checked.. ill look

[707]

yes, its throwing 5 long blinks and 5 short ones. whats that mean? its a redtop also

[SpeedRacer1]

Well thats good or bad depending on how you want to look at it, 55 is an all good code.

Is fuel reaching the pistons? Does the spark plug tip smell like gas? Was the CAS ever removed?

[707]

the cas was never removed, and yes the spark plugs smelled like gas so i cleaned them

[SpeedRacer1]

Well if the plugs are firing then the CAS is working. Could you have just flooded the engine?

[707]

i dont know, that would make it not start???? what should i do?

[SpeedRacer1]

Sometimes when an engine hasnt been started in awhile the fuel will dump into the cylinders flooding the plugs. Too much fuel causes the plugs to not be able to fire for awhile. A few ways to remedy this are 1)Burn the electrodes clean of gas and other buildup, 2) Try to dry the plugs with something (air, towel), 3) Let the gas evaporate off the plugs inside the engine, can take a few minutes.

This has happened to me before a few times, but chances are this is not your problem because it is uncommon.

Is the engine catching at all or just cranking?

[707]

its just cranking... i cleaned the plugs and it sat for a while, ive been trying to get it started all day

[SpeedRacer1]

How did you confirm it had spark and that the injectors were firing?

[707]

i pulled out the plug, left it in the wire, grounded it and turned over the motor and it sparked. and i put my ear next to the injectors while someone cranked it. they were ticking

[SpeedRacer1]

Is there a possibility timing is off? Good battery?

[707]

battery seems to be good, the motor was just running fine a couple weeks ago out of my roommates car that was crashed so i dont think the timing would be off

[SpeedRacer1]

Wiring on the SR is good? Is compression still good? Plugs fouled?

[707]

is it possible my fuel filter is clogged??? should i try my stock one intead of the 300zx one my roommate gave me?

[707]

the car just ran very recently with good compression. wouldnt the plugs not spark if they were fouled?

[SpeedRacer1]

Fuel filter is not likely, usually fuel lines get crossed on accident, but you can switch back if you would like. Plugs will fire when they are not in good shape, but the condition of the electrodes and tips can have an effect on how the engine runs. Did the ECU, wiring, and all the other componants come with the engine?

[707]

everything came with the motor... there is a couple sensors on the transmission i had to splice and havent hooked up yet but that wouldnt make it not start right???

[SpeedRacer1]

None of those sensors affect the engine running.

[707]

is there anything else it could be??????

[SpeedRacer1]

Its tough to try and diagnose over the internet. If you have fuel, spark, proper timing, plugs that havent been flooded, and a good battery the car should at least catch. Coolant temp sensor can sometimes cause the ECU to give the wrong amount of fuel thinking the car is cold starting or warm starting.

Is it S13 SR into S13? No wiring was modified since it last ran? You can hear the fuel pump running in with the key in the on position?

The off the wall stuff would be next, things like crossed fuel lines, major vacuum leaks, things blocking the intercooler pipes (like a sock, I have seen it), some messed up wiring somewhere.

[707]

hahaha a sock. to tell u the truth there is alot of plugs not hooked up but nowhere for them to go as far as ive seen in the past 3 days ive been working on this. i dont think there are any lines crossed but i will definately double check. if u have any other advice thatd be great. thanks alot for the help

[707]

SO I REALIZED, IM NOT GETTING FUEL!!!! THERES PRESSURE FROM THE PUMP, THE INJECTORS ARE WORKING BUT IM STILL NOT GETTING FUEL. what could this be???? what kind of wiring issues might i have? i think its electrical because the motor ran fine

[SpeedRacer1]

Try reversing the fuel lines up at the engine.

Did you check if you had fuel??

cuz if you dont.....
